# Question
Title: How to log app run time
Long story short, I need to log these things some apps: The starting time of the app, total running time and the end time of the app.

**Edit: I would want to run this a whole week, to see how much time these apps are using** .

# Answer
Here is a workaround you could use.

Objective: Create a Task make an application runtime log.

**Profile**

Application \>\> Select target application e.g Facebook app (Tap back to exit out of this profile.

Long press the first context and select Add \>\> Day \>\> Select number of days e.g 7 days

**Tasks**

**Task 1 (entrance) You can name it Facebook login time or anything.**

1. A1 Variables\>\> Variable Set \[Name: %Logintime to %DATE %TIME (leave everythin as is)\]

Tap back to perform second action.

2. File \>\> Write File \>\> \[File (give any name e.g sd\_card/Facebook logtime.csv) Text (Start, %Logintime) Tick Append, Tick Add New line\]

Save and exit this Task

Create another task

**Task 2 (exit) You can name it Facebook logout time or anything.**

1. A1 Variables\>\> Variable Set \[Name: %Logouttime to %DATE %TIME (leave everythin as is)\]

Tap back to perform second action.

2. File \>\> Write File \>\> \[File (give any name e.g sd\_card/Facebook logtime.csv) Text (Start, %Logouttime) Tick Append, Tick Add New line\]

Save and exit this Task

*Explanation: When the Facebook application is opened, the log file (that .csv file you created) is written the start time, and when you exit it writes again the end time, such that after a week it shows time you used the facebook app, hence you can calculate the time.*

Please note, to perform calculations within tasker is possible but is advanced so I just did it the simple way.

Happy logging!

# Question
Title: Can multiple androids be paired to work on the same task?
PlayStation 3 consoles were combined to make a super computer. Can the Android phones be modified in the same way? Could I use the processing power of 2 phones to play a movie that 1 would not.

https://www.engadget.com/2007/08/11/sonys-warhawk-server-farm-is-made-of-ps3s/

# Answer

It depends on the workload but you absolutely could use Android phones as a cluster in much the same way they did with the PS3's.

You'd probably need some sort of server-client setup. With a server setup to manage the clients, assign work and manage the overall process and the clients setup to complete the work.

This is an interesting idea, for sure!

# Question
Title: Reboot drops battery by 2% each time
I have installed custom ROM, Official Lineage OS 14.1 on my Redmi 1S. I used to reboot device sometimes. And, I noticed that each time after reboot, battery percentage reduced by 2%. I also, tested on my Redmi 3S, running stock ROM, But, there, it won't drop battery. Does the device really use 2% of battery to reboot?

# Answer
# Yes and no

It does take energy to reboot, but it isn't the phone rebooting that takes this energy. The energy is lost through hystersis which the battery algorithm is accounting for.

Krexington\_III, who worked for a summer as a fuel gauging engineer for a major cellphone manufacturer in northern Europe and says:

> Hysteresis is simply the fact that once we've got the battery discharging, if we stop discharging it (say, by turning the phone off), it will keep on discharging by itself for a short while.

(Paragraph 3)

https://www.reddit.com/r/explainlikeimfive/comments/1qrdc9/eli5how\_do\_digital\_devices\_know\_how\_much\_energy/

Phones need time to tell how much energy the battery has, and don't keep track of the battery while it is off. Your phone was programed to estimate that 2% was taken away while the phone was off due to Hystersis. Your other phone does not make this estimation (the user won't notice).

I suggest reading Krexington\_III's post for (a lot) more information on how phone batteries and their algorithms work.

# Question
Title: Widget to display Outlook calendar
I am coming to Android from Windows Phone and trying to replicate my old experience, which included showing my next appointment on the home screen. I understand there are things called widgets that can do this. My problem is that every widget I've tried shows my "Google Calendar" (which seems to consist in its entirety of public holidays) rather than the events in my Outlook calendar. I've installed Outlook on the phone and if I click the Calendar icon at the bottom, I see the events. But how do I get those to show up in the widgets?

# Answer
> 6 votes
I was never able to make any of the "top" calendar widgets, including those recommended here, show my Outlook calendar. They just showed my empty Gmail calendar or Google calendar or whatever.

**However** I eventually discovered, way down at the bottom of the widgets list, that there was already an Outlook widget installed and waiting for me:

Putting the Outlook Agenda on my "desktop" does exactly what I want:

# Answer
> 0 votes
There are tons of calendar widget apps you can download from the Google Play Store, and a lot of them you can choose which of your personal calendars to display. There are also plenty of apps that just show agenda content- like your next appointment in a nice text widget.

Personally, what I use is Kustom Widget, where you can make your own agenda widget.

Title: Will Netflix still function properly on my LG K7 if I root it?
I recently got a new phone (LG K7, MetroPCS) and there are some things that I wanted to do, which require root access.

I know how to root, and I know some apps won't work on a rooted device (Android Pay, Samsung Pay, etc.) But on howtogeek.com it also said that some paid TV/video streaming services will not work.

I would like to know if this applies to Netflix, if it does, I probably won't root it, as I would like to continue using Netflix. Thanks in advance!

I was using Netflix app on rooted device without problems, abouth month ago. So you probably won't have any problems.

# Answer
> 0 votes
You will still be able to view downloaded content, it only affects streaming (Netflix error 0013). Don't do those tricks you find on sites, it is useless to rename libs etc.

The only solution to get another build of Netflix - get them from Netflix, not other sites. You must permit installation of APKs from untrusted sources to do this. You will have to experiment with different builds, unless you find a page where someone with your exact phone type writes which build to get (from Netflix, nowhere else).

Title: S4 Wont turn on unless removing battery then turns off after 2 seconds
So, my Galaxy S4 turned off randomly today during charge. I attempted turning it back on via the power button but it would not respond.

Then I tried taking out the battery and replacing it, the device vibrates with the Galaxy S4 logo showing up for about a couple seconds, then the screen goes blank again.

I even tried placing a battery from a different S4 - still doesn't work.

Try booting into recovery mode and seeing if it turns of there

if it doesn't that means your software is corrupt and a factory reset/format cache from recovery mode might fix it

to access recovery mode hold power button+ volume up + home button at the same time while the device is off

I had the same problem. Most likely it's the power button problem, where it's always stucked inside, or depressed in. That makes your phone turns on then turns off by itself. I had the same problem. I found this great video on how to fixes it.

# Question
Title: Invalid sim card/no sim card inserted error
So I will do my best to explain what's been happening and what I have attempted to fix the issue. First off, I have a g3 us990 under US Cellular running octos marshmallow (custom ROM) along with TWRP and have been for well over a year.

Last week I noticed I had no signal in my phone and a message on the lock screen saying invalid card. I have been able to temporarily fix it anywhere from 30 mins to a day where it then would stop and show the message again and texting/calling would stop working. I have tried restarting it(random if it would fix it or not), reinserting the sim card(found sometimes the no sim card is inserted error would show up), factory resetting(same as restarting), restoring from a back up(still nothing), and I have even went out and got a new sim card and activated it to see if that was it.

My next plan of action is to restore back to stock using the LG flash tool. But I feel that won't work either. Another idea of mine was purchasing a new sim card reader off eBay and doing some soldering, but I want that to be a last resort.

So at this point I am thinking it is the sim card reader in some way, but I would figure that if it was the sim card reader, it wouldn't work at all. I'm hoping someone that has had experience with this before knows a fix or any other ideas on what to do because I am just about out of them.

# Question
Title: Trading clipboard contents between phone and computer
Is there a way to send information on my phone (for example, an SMS that I started to type, that got way too long, and that I decided I want on my computer to send as an email instead) through the clipboard? There are ways like sending myself emails, but they're not exactly great, on top of me finding absolutely no decent way of using email on my phone.

In an ideal world, on my phone, I would like to have a "right-click" (hold-the-tap) option, "Send to PC", and if Wi-Fi is enabled, I would just go to my PC, perhaps authorise the received clipboard (not sure that would be necessary or convenient), and then just Ctrl-V somewhere, and voilà, it pastes what came from my phone in my browser/Skype conversation/Word document/etc.

Also, I would very much like a similar option to go the other way. To send things typed from my computer to my Android device. In an ideal world, through a right-click option called "Send to Phone", or even a keyboard shortcut like ctrl-alt-shift-C. But this part, I'm not sure if it wouldn't belong on SuperUser more.

My PC uses Windows 8. My phone runs 2.3.6 Gingerbread.

My phone is a Samsung Galaxy Q (SGH-T589W).

For your information, this is almost the same phone as the Samsung Gravity Smart. Or literally the same phone. These dual names confuse me.

Samsung Kies does NOT work for me, so no use mentioning it (unless you can make it work unlike the Samsung support people I contacted, but this would belong in another question).

# Answer
If all you care about is the clipboard sharing, you might want to take a look at ClipSync. This app allows you to share your clipboard between multiple Android devices and your Windows PC: Copy on one device, and it appears in the clipboard of all others. At least that's what the app description says (all Windows I have are just for fresh air and light coming in, or to look out of them (not Out-look), so I cannot verify). A 4.5 star rating suggests it works -- and it's only 150kB "big".

If you want a bigger benefit, take Compro01's advice and have a look at Airdroid. It's a great app, and lets you maintain your Android device from any web browser in the same WiFi network really nice (edit your contacts, write SMS, browse pics...). An beside that, allows for clipboard sharing.

Title: Take bug report for specific application
I am starting Android development, and I am looking for a way to get a bug report from a user's phone.

I know about the `Settings / Developer options / Take bug report` system, but from what I have seen, it dumps *all* logs from all sorts of apps I don't really care about.

Is there a similar method which would generate a similar file, with just logs relevant to my app?

(I also know about `adb logcat`, which I can then filter on my computer during development, but it's not easy asking users to do that!)

Title: Preloading images over WiFi from New York Times app for Android?
I've set the NYTimes app to download over WiFi twice a day. But it just downloads the articles, not the pictures. So if I'm out and about, I either get no pictures or I burn cellular data.

How can I get this app to download the pictures over (free for me) WiFi?

# Answer
There's an option as of app version 6.10 to preload images.

However it only preloads some images, leaving you at risk of using a fairly substantial chunk of data simply by flipping though sections in the app. As of this writing, there seems no better option.

Title: Device Can't Power Down
I have an Android device which had a custom os..It was for educational purposes and I could not even open another app on it. After the end of the subscription period I thought of using the device. I tried opening it's recovery mode but instead opened some factory or diagnostic mode which was in Chinese. By mistake I pressed the power key to select an option ending with "emmc" and now It boots but shows a black screen with navigation buttons and time...Any keys pressed make no effect and I am unable to shut it down. When I press the power key for a few seconds it reboots but shows the same screen. I just want to shut it down somehow. Please Help!!

**Edit**: I found a way to shut my phone down. I connect it to my pc and then press the power button for 10 seconds then the screen goes off and the charging percentage shows up after a couple of seconds, I pull the usb cable out and the screen disappears and voila ! My phone is switched off.

Title: Prepare SD card for removal from Cyanogenmod 13 HTC Desire HD A9191
I installed CM on the above phone. I wanted to remove the SD card, but when it boots up again the phone says 'Encryption unsuccessful'. It works again if I put the card back in and reboot the phone.

I want to move the SD card to another phone, and have this one without an SD card. I know that it works without an SDcard, but how? Do I need to move the /data partition somehow? How do I do that?

Edit: It was the CM build I used, which was aceopt. The *opt* part means that it uses the SD card as internal storage. So I need another build if I want to take the card out. Unfortunately, there doesn't seem to be a non *opt* version of CM 13 for this device, so I'll have to go with 12.

Insert your SD card in your phone, reboot it, then go to Settings - Storage & USB, press "menu" button and choose "format as portable". You should be able to use your SD card on other devices after that.

# Question
Title: How to set a tethered Wi-Fi connection (tethered to another phone via Android personal hotspot) as "metered" connection
I have a number of apps set to "Download on Wi-Fi Only" on Android. But the moment I tether, the phone considers itself on Wi-Fi, even if the upstream device is a metered 3G/LTE connection.

Under Windows 10, I can declare a given Wi-Fi connection to be "Metered", and thus save data usage. Is there an equivalent on Android? Setting the tethered phone to "Data saver" is a partial solution only.

# Answer
There is a rather hidden feature, that will let you achieve this:

This option is found under Settings \> Data usage (Wireless and Networks).

* Tap on the three dots in the top right corner, and press "Mobile Hotspots." (In android 4.3) In later versions of android the similar option is "Network restrictions" \> Metered connections

Next you'll see a list of saved wireless networks, and you can check the ones which are mobile hotspots.

**Edit**

I have included the screenshots for Android 7, since interface and options are different from Android 4.3 above:

Such that the options are found under Settings \> Data usage (Wi-Fi) \> Network restrictions \> Metered connections

In this way Android applies the same data restrictions as it does with "Data connections" so no data hogging.

# Update

Other devices like Huawei have this setting hidden but can be also enable using :

After setting up adb, follow this proceedure to set a metered wi-fi network.

> * In a command prompt or terminal, execute the following command: `adb
>  shell`
> * Type the following command into the command prompt or terminal to get a list of all saved WiFi networks: `cmd netpolicy list
>  wifi-networks`
> * You’ll be given a list of saved WiFi networks with a true/false boolean value. True = metered & False = non-metered.
> * So from here, you can enter the following command in a command prompt or terminal to change the setting: `cmd netpolicy set
>  metered-network Wireless true` (In this case the SSID is “*Wireless*”)
> * You can always revert the setting to false if you want to switch it back to a non-metered network.

Hope this helps

# Question
Title: Full Backup of non-rooted device in 2017
My Galaxy S7 has developed a problem with it battery (where it is continually turning off / rebooting) and so I need to get it repaired/replaced by my insurer.

The only issue is that, for data protection, they wipe every device before repairing.

Although I have back ups of most of my apps, all my photos, contacts & sms messages I have a lot of settings, multiple non-web based email accounts etc. set up on the phone so having to start from stratch would be a real hassle.

I therefore want to back up the entire phone, like a drive image, onto my Macbook so that I can simply copy the backup onto my new/repaired device once the battery issue is sorted.

I thought I had found a solution in this thread: Full Backup of non-rooted devices

However that is nearly 5 years old and so the instructions do not match the current version of Android SDK, seemingly now called Android Studio (the previous instructions ask you to locate a folder called 'platform-tools' but this isn't created by the current version of the SDK).

Anyone know of any updated instructions on how to do this?

Thanks!

# Answer
Nothing really crucial changed since then. Android SDK is now installed together with Android Studio, however can be installed separately. Platform tools, which contain ADB, are now delivered separately from SDK. Here is the link:

https://developer.android.com/studio/releases/platform-tools.html

After the installation you will find adb binary in `platform-tools` directory. All other points from those answer are still true.

Consider also TWRP backup possibility, which though, requires TWRP.

Title: Disable Briefing Notifications on Galaxy S8
It seems once or twice a day, I get some Briefing notifications on my Galaxy S8. The icon for these notifications appears similar to Flipboard, though I don't have Flipboard installed as a standalone application.

I have the Bixby Home Screen turned off, and would probably even disable its dedicated hardware button if I could do it without rooting.

# Question
Title: Downgrade Android 6 Marshmallow version
Okay so in the first version of Marshmallow it was possible to move apps to the SD card without having to set it up as internal storage. Now they removed this feature, only allowing to move apps when you are using the SD card as internal storage. Does anyone if it is possible to downgrade to that first version of Marshmallow where it was possible to do this?

# Answer
It is possible by using TWRP or any other custom recovery of your choice but you must have desired firmware file as recovery flashable zip archive first. Unmounting adoptable storage and performing all available wipes from recovery before downgrading is also required. You can find detailed instructions on what custom recovery is and how to install it on specialized forums (I recommend XDA Developers one) as well, as desired firmware version for your downgrade (head to your device thread and seek there if you interested).

Title: Xperia Z5C can't receive SMS
I just followed Sony's tutorial to unlock and flash the ROM to AOSP. I also compiled manually the kernel in the process. I imported my `mmssms.db` as well to keep my messages.

The stock messaging app kept crashing when opening a conversation, so I tried to clear the `mmssms.db`, but then I simply can't get to the redaction screen. I can select contacts but that's it. I tried another app that can send SMSes successfully, however I don't receive anything.

That's probably a bit confuse but I'd like to know where the issue could be, where to look and/or what useful debug infos I could get & share.

I tried to put my sim in another phone: works I put another sim in my phone: can send, can't receive as well.

Flashing it with the same `bootimg` and `system` without importing the `mmssms.db` fixed it. To be sure, I imported it again and it did the same as before.

It therefore seems that the replacing the DB is a bad idea, there must be another way.

Title: Unbrick An AT&T Sony Xperia Ion
Yesterday I was looking for a CWM rom to flash and I found this: https://forum.xda-developers.com/showthread.php?t=2682782 . I had flashed this from my TWRP recovery that I got from here: https://forum.xda-developers.com/showthread.php?t=2634375 . While I was flashing the rom, the progress bar never moved but after about a minute or so it said that flashing the rom was successful. After I tapped Reboot System the screen just went black and wouldn't turn on. I wiped dalvik-cache, cache, and data prior to doing this. My bootloader is locked and flashtool does not work because of this. Any way I can unbrick my phone? My device is a LT28at.

Edit: After leaving it on the charger, I got a red light and after a few seconds, it turns green for the same amount of time then goes back to red. And if it matters, I have disconnected the built-in battery and plugged it in and it gave me a red blinking led.

# Answer
Calm down, your phone is not dead, you still can revive it simply by flashing a stock firmware using Flashtool. You should be carefully flashing Sony devices when having a locked bootloader.

* Download the firmware here
* Download the Flashtool here and install it.
* Go to the folder that contains the Flashtool (Usually C:/Flashtool) and launch it by clicking on either FlashTool.exe or FlashTool64.exe, whether on 32 bit machine or 64 bit)
* Return to the folder and open the Drivers folder, install the drivers.(C:/Flashtool/drivers).
* On Flashtool, click on the thunder icon, select Flash mode.
* Now you should open the firmware select Window. The source folder address should be `C:\User\your_name\.flashtool\firmware .` Copy the firmware you've previously downloaded to that folder. It should now appear on the selector window.
* Now click on flash button. Plug the USB cable while holding the volume down button or back button. Drivers should be installed and the flashing process started.
* Just wait until the end.
* Et voilà.

# Question
Title: How can I transfer a playlist straight to my PC?
The key is that my music files are all over the place in separate folder in my phone. It would be too time consuming to sift through every folder and pull out the individual song files that are in my playlist, not to mention some of the files are weirdly named so I'd end up missing some.

I'm trying to move just the songs that are in said playlist so I can burn them to a CD. The music app on my LGG4 let me export the playlist into an ".m4u" file but I'm not sure what this does or if it even helps. Any guidance? Thanks in advance.

# Answer
I solved this with the help of 2 free apps (with Android 4.1.2 on a Samsung S3 mini), because Android can't do this directly:

* Total Commander
* Playlist Backup

Install them from the Google Playstore, then continue as follows:

1. With Playlist Backup, export the Playlist as text file. Store it in a temp folder on your mobile.
2. To copy the MP3 files contained in the playlist, open the playlist in Android's built in player, then select "Send via" in the context menu. Select all files. Then, a list of apps is shown. Select Total Commander. In Total Commander, pick the local temporary folder (on your mobile) to copy the files into.
3. After Total Commander has copied the files, connect the mobile with your PC and copy the temporary folder to the PCs harddisk (containing the playlist text file and the MP3 files)

Finally edit the playlist file to adapt the paths in it so the MP3files are found by the PC player software (e.g. WinAmp or any other MP3 player which supports playlists).

A strange request I know... but I am quite keen to disable mobile data from my phone permanently (as opposed to just switching it off in the settings) so that I can only browse the internet when I'm connected to Wifi.

I've tried getting my network provider (O2) to do this with my account but they said it's not possible.

Is it possible to achieve this in Android instead? I'm basically just looking for a way to 'break' it... whether that's by installing some kind of app then that would be fine (perhaps if I could then return it back to normal with a factory reset)

I'm not fully sure wether you can permanently disable data or not but you can always create a dummy APN and select that as default. With this, even if you enable data accidentally via toggles, it would still not connect. The best and sureshot way to stop mobile data is to delete the APN's (Access point names).

Almost all options require root.

The setting which is of interest to us is `ro.build.version.release`.

> ro.build.id=JSS15J
> ro.build.display.id=JSS15J.I9505XXUEML1
> ro.build.version.incremental=I9505XXUEML1
> ro.build.version.sdk=18
> ro.build.version.codename=REL
> **ro.build.version.release=4.3**
> ro.build.date=Tue Dec 10 14:28:08 KST 2013
> ro.build.date.utc=1386653288
> ro.build.type=user ro.build.user=se.infra
> ro.build.host=R0210-09
> ro.build.tags=release-keys
> ro.product.model=GT-I9505
> ro.product.brand=samsung
> ro.product.name=jfltexx
> ro.product.device=jflte
> ro.product.board=MSM8960
> ro.product.cpu.abi=armeabi-v7a
> ro.product.cpu.abi2=armeabi
> ro.product.manufacturer=samsung

Just change it to 7.0 and Android will be fooled and think that you **already** on Nougat. For 100% fooling you can also change `ro.build.id`, `ro.build.display.id` and `ro.build.version.incremental` properties to `NRD90M`, `NRD90M.G955FXXU1AQDG` and `G955FXXU1AQDG` values correspondingly (aka Nougat values).

Reboot after the applying changes.

2. If you lack root, you still *can try* Titanium Backup. But this way can also require root though.

Your phone is a Mediatek device. So you need flash files with Scatter and SP Flashtool for flashing. You can get all here

Edit:

Steps below are for flashing Mediatek devices using SP Flashtool and a Windows computer:

**What you'll need**:

* Download your device ROM files. You can find it here
* Download SP Flashtool. Can be found here
* Download Mediatek drivers, or here (for Windows 10)

**How you'll do it**:

Downloaded files should be ziped (rar, zip or 7z format), unzip then proceed by installing the drivers and . Also unzip SP Flashtool and the ROM file to somewhere you can access quickly - say in the Desktop.

1. Go to the SP Flashtool folder and launch it. SP Flashtool opens on **Download** tab. On `Scatter-Loading` field, click on **Choose**. This will open a file selector dialog. Browse to the folder where ROM files are located. Select the scatter file. Flashtool should load all files now.
2. Click on the drop-down list and choose `Format All + Download`
3. Now power off the device. Click on `Download` then connect the device to the computer with a USB cable.

Flashing should start and simply wait for the software do its things.

The flashing ends when the green check mark pops up.

Note: *This can be also solved by flashing a custom recovery, such as TWRP and manually mount the partitions*.

Title: No Signal Sign on Samsung S3 GT-I9300 Possibly After Deactivating Mobile Tracker
I have a Samsung Galaxy S3 GT-I9300 since 2012. I've never rooted it. The last app I've installed was a few months ago. I'm running Android 4.3.

Yesterday, for the first time ever, I've got "Uninstall harmful app. 'Mobile tracker' can damage your device." notification, exactly the same as in the following thread: Uninstall harmful app. 'Mobile tracker' can damage your device.' At first, I discarded it but when it happens again and since it was from google, I said 'OK'. Later that day, I don't know if it is due to this or not but my phone started to show no signal sign and not recognizing my SIM card. I re-enabled this mobile tracker from Application Manager but still I get the same no signal sign.

When I put another SIM to my phone it works, when I put my SIM to another phone it also works. It only doesn't work when I put my SIM to my phone. I cannot understand how this can be possible, but it is the case unfortunately. Any help would be very much appreciated as I do not want to reset my phone.

# Answer
I too have a Samsung galaxy 3 that I brought in 2012. This morning the same error message and a warning triangle appeared on my phone for the first time. I contacted Samsung support - the rep hadn't heard of this issue before - but talked me through a factory reset. Did this and the triangle & message have gone. Would have liked to have found a solution that didn't involve a factory reset though. (She also advised me to delete my Google account first - bcos otherwise apparently it's a little difficult to reinstall afterwards..)

# Question
Title: Always On VPN on android does not reconnect
I live in UK and recenlty I felt the need of getting VPN. Everywhere.

There is an option in android 6.x: Always-on VPN, but there are two issues with it:

* It does not reconnect after lost connection. That usually means that whenever connection drops for some reason you have to Unlock phone -\> Go to Settings -\> More connection settings -\> VPN -\> More -\> Always-on VPN, change server you like to connect to, click OK and wait ~5s for it to recconect. Why wouldn't it reconnect automaticly (or maybe it doesn't do that only in certain situations)?
* In case server is not available I would like to be able to establish more than one VPN service, so phone tries first one, if it can't connect than go to second one, than third etc. Is it possible?

# Answer
I also have this problem and have found it particularly annoying. I'm using PIA and their app just sits there unless I bounce the connection. I've just raised a ticket with them about it.

However, I suspect that this is more of an Android problem as I also see this behaviour when using OpenVPN. Specifically, when I drop the wifi connection and the phone switch over to the mobile data connection the OpenVPN client logs "write udp : network unreachable".

Looks to me like the VPN clients are binding to the current primary network interface and when that changes (by whatever means) they are not detecting that and switching to the new one.

I don't have a solution at the moment but I'll report back here once PIA respond to my ticket.

# Answer
I suggest using OpenVPN with TCP to keep connection stable and more reliable. it also depends on the VPN service you are using. to understand why vpn fails you will need to take a look at the logs.

I don't think Android VPN natively offer always on feature, to get such functionality, you might have to use an automation service, like Tasker.

Title: Impossible to transfer mobile banking app data between factory resets
I have two banking apps installed on my device: https://play.google.com/store/apps/details?id=com.infinum.rba https://play.google.com/store/apps/details?id=hr.asseco.android.zaba

It is impossible to transfer the app data on the same device between factory resets in a way where it is not needed to reactivate the apps using the activation process of the given banks. I've tried backing up the apps and their data using ES File Explorer PRO and App Cloner Premium. I've also attempted to copy the app data and the apps manually between system to no avail.

Since the device is the same, the IMEI is the same, the operating system is the same, i see no reason that the app data couldn't be reapplied after a factory reset, resulting in a fully functional mobile banking app - however I've found no way to do so, nor have i found which mechanism the apps use that prevents doing so.

Help me out here.

# Answer
Assuming that the IT department of the bank has implemented some sort of check in their Android app to ensure that you can't restore its data between different installations (which also includes factory resets), they're probably using something along the lines of a unique ID such as ANDROID\_ID.

This answer (and specifically Seva Alekseyev's comment) explains what I suspect is causing your issues; this ID also changes on factory resets. This is purely a security measure and a very good one, because it would be terrible if I could log into your Google Play account on my phone and restore your banking app's data from the cloud, allowing me to access your bank account, right?
> 1 votes

# Answer
Im sure that it should be possible to get all important data with root and transfer it this way.

*However*...I cannot provide you with an exact solution how to do this. Additionally to this, some banking apps wont work / show a warning if you are using root because of security reasons.

Since i dont use this apps personally, rooting your phone might result in them not working anymore

Title: How To Fix: Data Recovery from Broken Screen without USB Debugging
I have the OnePlus Two phone whose screen was broken a while ago and i want to back up some of my pictures and videos which were stacked in its internal memory. Please note the below points for better understanding:

1. Screen can show content but the touch is not responsive.
2. I don't have an OTG Type C connector.
3. USB Debugging was not active before phone was damaged.

# Answer

Even if you did not activate `adb` it may be active when the recovery is booted. (At least for recent versions of TWRP it is.)

Depending on what you want to do this may be enough. If it is not you could try enabling the OS's `adb` from recovery `adb` (see here for an example of the relevant configuration files). After this is done adbcontrol is can be used to remote control your phone using a computer and `adb`. If you use an unlock pattern that includes a polygon of swipes this will not help (a pin would be fine).

In this case you would have to reset the unlock code, but I messed up something on my phone which may have happened while doing this, so I am not comfortable giving you advice on how to do it. In any case make backups (e.g. via `adb pull`) even of you configuration files before doing any modifications.

Title: How to access a video file that an app is hiding
There is this app that uploads some videos. You can watch the purchased ones only through the app! (free videos can be downloaded in pc with IDM)

So I purchased a video and downloaded it so I can watch it offline, and my phone's free space decreased by 1G. I want to copy and save that video on my laptop, but it's not accessible in the phone nor the laptop. Is there any way to find that file?

My phone is a *Galaxy Note 3*. I checked some programs ("Wondershare MobileGo for Android" and "YouWave Android") but they didn't work...

The app is V – Live Broadcasting App. For the other videos I need at least 7G free space!! I was thinking about moving the videos to my laptop so I can download the other 6 episodes :(

# Answer
> 1 votes
Most likely you can see it only from within that app: the file will be stored in the app's "private" directory where only itself has access to (unless you use "root powers"). See my answer here for details.

Even assumed you'd manage to extract the file (e.g. using root powers) and transfer it to your laptop, you most likely won't be able to watch it: those applications normally use DRM (see these questions for details), and their media files are encrypted.

Without knowing the identity of "this app", it's hard (or rather impossible) to say anything more specific.

title: TouchWiz What does it DO?

# Question
Title: TouchWiz What does it DO?
What does TouchWiz actually DO? In plain English. And if it's really necessary to have, why is it made an option?

# Answer
> 3 votes
TouchWiz is *not* just a launcher. As advertised time and again in various places, its full name is "**TouchWiz UX**", with UX standing for User eXperience.

Early on when TouchWiz was in its infancy (TouchWiz 3/4), it was indeed not much more than a launcher: functions added by Samsung are few and not tightly integrated with the OS, and the launcher itself was easily ported.

Then things changed drastically when Samsung introduced TouchWiz 5 (dubbed "Nature UX") on their Galaxy S III, massively overhauling the interface (again, *not* just the launcher - lockscreen, notification drawer, status bar layout, icons, etc.), plus integrating key functions such as S Voice and Smart Stay.

As Samsung pushed flagship phones by generation, they introduced more and more functions, most if not all of which are tightly integrated into the framework, to the extent that there are no longer ports to other devices (except ones that port the whole ROM over).

**TL;DR**: TouchWiz is your device's user interface and experience. It controls the way you see and interact with the device.

As for its necessity, you could easily replace the launcher since Samsung did give you an option for that, but the rest of the UX (yet again, *not* just the launcher) is locked in, to act as a differentiating factor for their devices on the market, and to keep customers inside their ecosystem (e.g. using their apps brings them revenue). Unless you decide to dive in the world of custom ROMs (voids warranty), it's not an option per se.

Reference: Wikipedia

# Answer
> 0 votes
TouchWiz is Samsung's "Launcher", essentially comparable to a computer's GUI, like Windows.

It allows you to manipulate your environment, launch apps, set options important to you like networking. It can manage Contacts, documents, and similar, as personal data.

It allows you to communicate to the world through its browser, phone, and media apps. It allows the launching of social apps, and much more.

It is optional, because its interface, and the buttons, shortcuts, and such, are a particular target for those who can "do better" or "different", and have created "Launchers" to compete with it, and hence replace it.

# Question
Title: Will a US tablet imported into the UK get OTA updates?
I would very much like a Samsung PM-580 (Tab A 10.1, with S Pen) but Samsung are either being slow to release it in the UK, or potentially might not at all. Via Amazon.com I can import one to the UK at what I consider to be a reasonable price, and I can see no technological problems with using it here.

However this tablet is getting an OTA update to Nougat very soon (if not already), and obviously I'd want this for mine. So:

> Will a US-serial number tablet still get its OTA updates in the UK?

It would seem odd to me for the answer to be "no", since this would involve Samsung insisting that you connected to a network in a particular location before giving you the OTA update. But it would be reassuring to know for definite before investing my cash, and perhaps others have had similar experience?

Title: Galaxy S5 Battery Drain
Galaxy S5 (unrooted)

My battery drain isn't dreadful yet, but it isn't getting better.

I can't narrow down what is causing it. I have tried keeping my sync turned off, keeping google location reporting services off, even keeping my data off. I can't narrow down at all what is causing this.

Anybody else have an idea or in a similar situation?

# Answer
Had the same situation, I rooted and installed some app management apps, and stopped autoruns of many apps like maps, games, etc. I also removed some stock apps that I don't use which runs in background like Samsung apps. I recommend "System Cleanup" app for this .

# Answer
In the system settings look at the apps that consume the most of resources. But it is not always possible or desirable to remove these apps.

I have universal advice. Just reboot the phone sometimes. It reboots quitely fast and after the rebooting about half an day it drains the battery less than the phone which is not rebooted in weeks.

# Question
Title: Remove Whatsapp backup from Google account that is no longer used
Last week I tried to move my Whatsapp account to a new phone. For some reason it didn't want to restore the backup, even if I moved the backup file manually. It turned out that the file was encrypted using another Google account.

This is an old work account. It's inactive, and I can still login. That made it possible to restore my backup, so I'm happy with that. But I don't work there anymore, and I don't want the backup to be in that account, even if it's encrypted. And even if it's encrypted, how does the new phone know the unlock code?

**Questions**

* How can I move the new backups to my normal account? Will deleting the old account suffice?
* How can I remove the old backups from the old account?
* Could someone else with access to the old account restore my entire Whatsapp history?

# Answer
> 1 votes
WhatsApp has a nice FAQ article about their Google Drive backup functionality, so I'll refer to that below.

## How can I move the new backups to my normal account? Will deleting the old account suffice?

No, you will need to configure WhatsApp to store backups in the new Google account you intend to use from now on. See the section called "*Change to which account you want to back up your chat history*".

## How can I remove the old backups from the old account?

Please view the section called "*Deleting your backup file from your Google account*". Aside from clicking "Delete hidden app data", I'd also advise clicking "Disconnect from Drive" afterwards so the link between WhatsApp and that Google account is also broken on Google's side.

## Could someone else with access to the old account restore my entire Whatsapp history?

Yes, provided that they also have access to the phone number associated with that WhatsApp backup. If they only have access to your Google account, then no, that's not enough: "*After verifying your number, you will be prompted to restore your messages and media from Google Drive.*"

# Question
Title: google play services constantly crashing
My sister's got cyangonmod 11 to have android kitkat on here sony Xperia P.

At first it was smooth but now she's facing constant crashing of google play services app.

I've seen these links before :
Google Play Services crashing constantly

Cyanogenmod: Google Play Services keeps crashing after update

Google Play Services and Play Store crashing

The error message I get in the logs is different from the first question, I tried to install google play services from apkmirror as suggested by the second answer, I tried to install versions 10.2.98 and 10.5.53, the version needs to be `030` as suggested by apkmirror and I'm sure about this.

Reinstalling google play services from apkmirror and clearing data does solve the problem at first but the next day or so it comes back.

The output of `adb logcat *:F` is this :

```
F/libc    (25812): Fatal signal 7 (SIGBUS) at 0x00000000 (code=128), thread 26060 (pool-48-thread-)

```

I'm sure those are the crashes because that's where I say the crash message.

I don't understand that `not same as in map : null` thing , could you tell what does it means ? and how do we solve this issue ?

My sister also tried the suggestion in this site : https://forums.oneplus.net/threads/found-a-fix-for-google-play-services-crashing-constantly.312830/ which didn't work.

If you need the full output of `adb logcat` or maybe `adb logcat *:E` I'll be happy to add them, the phone is also rooted and TWRP recovery is installed just so you know.

The problem solved, previously we had used System app remover to remove some system apps we thought we don't need, we removed google maps, as Izzy guessed google play services was looking for it without finding it ending in a constant crash.

When we restored back google maps app , cleared data no more crashes since then and the phone became faster and more responsive too :) .

# Question
Title: Is "high accuracy" mode in location setting, is what is known otherwise as A-GPS?
In high accuracy mode, the description says that WiFi/cellular network is used apart from GPS to determine location. How exactly are they used and what data does the cellular network provide?

# Answer
> 5 votes
Here are the basic technologies for location on an Android device:

* GPS (Global positioning system) - uses satellite signals to determine location without external request, high accuracy (~5 m), high power, high time to first fix.
* WiFi - uses WiFi scans and requests location from Google (possibly over cellular network), medium accuracy (~50 m), low power, low time to first fix
* Cellular - low accuracy (~500 m), low power; I am least sure how this works; there may be both versions where location is queried from Google as well as from the cellular provider.
* Bluetooth - uses Bluetooth scan and requests location from Google, high accuracy (~10 m), low power, low time to first fix, low coverage (doesn't work in many places)

A-GPS is assisted GPS. Without assistance, the Android device must listen for what satellites are currently overhead, which is slow and may require 10+ minutes to give a first fix. In A-GPS, the Android device uses its data connection (possibly cellular) to request which satellites are currently overhead. This reduces the time to first fix to ~30 seconds.

High accuracy mode will use A-GPS, but is not equivalent. In high accuracy mode, the Android device will first acquire a coarse location fix (say using WiFi) because this can be done in a few seconds, then it will improve this location fix with (A-)GPS when this becomes available. When this happens on Google Maps, for example, you will see the blue uncertainty area suddenly shrink in size because GPS is more accurate than WiFi or cellular positioning. High accuracy will provide a fix faster than A-GPS alone would.

GPS specifically refers to the US constellation of satellites, but people use this term to refer to the European (Galileo) and Russian (GLONASS) as well. Global navigation satellite system (GNSS) is the more appropriate generic term. The GNSS system used by your Android device depends upon its particular hardware. Your Android device's applications do not care which system is used.

In order to use Google's WiFi, cellular, or bluetooth location systems, you need to have an internet connection and be in an area with the corresponding technology covered and mapped. Your device scans for access points/towers/transmitters, and sends the results with signal strengths to Google, which estimates where you are. If the scan is empty, or in a place where that has not been mapped, your device location will be unknown. To be mapped, a sufficient number (as determined by Google) of people must have provided location information with scans for the area, like wardriving. It does not matter how you get your internet connection; you can use WiFi location with a mobile data connection because the results of a scan can still be sent.

# Question
Title: Turning on screen, flickering.. with logcats
Flickering is only noticeable in 10/255 and above brightness, in 255 brightness the flickering is extreme and it only occurs in the bottom part of screen(almost the size of keyboard)... So whenever I turn off the screen then touch the screen multiple times then turn the screen on again there will be flickering. It also happens sometimes if I plug the charger while screen is off.btw im rooted but this flickering was here since before i rooted. I tested lots of things like disabling almost all system apps and it was still there.

This live logcats are screenshotted right after turning on the screen so flickering occurs when it was created. I also noticed that flickering can only be seen when there is a layer of darkness created in the screen such as pulling the status bar, the home screen, and in the toast notification(just the whole bar of the toast notfcation)

So what exactly causes the flickering according to the logcats? amy clues on how to fix it?

The symptoms you describe sound much more likely to be a hardware problem than a software problem. You probably need to get the backlight of the screen replaced (or the whole screen, if it's an OLED screen).

You shouldn't have rooted your phone when it had an existing problem, if it was still under warranty. As things are, you'll need to pay to get your phone repaired. Take it to your local phone repair shop.

# Question
Title: Is it bad for Android phones to install and delete one app multiple times?
Can OS become slower by installing and uninstalling an app multiple times? Can this process make any harm to system, or is it safe to do it?

# Answer
No, it is totally fine. If you think your phone is slow clean the junk files or the cache using some good app like clean master and after cleaning everything uninstall it so that it doesn't run in background. Install it again when you think your phone has become slow and uninstall it again. Best way is keep a backup of the app so that you don't need to download it again and again.

Google has a weird mix of app settings, device settings, and a website to manage location permissions. I've found that the easiest way to access most of it is through *Settings → Personal content* in the Google Maps app:

As you can see I've gone through those one-by-one to disable all use of my location info by Google. You might also need to go to https://myaccount.google.com/activitycontrols/location.

Android Device Manager still works though even though my device is not actively sending things up. To remove your device from ADM entirely, you have to remove it from your Google account via https://myaccount.google.com/device-activity. This will naturally also sign you out of Gmail and the like on your device.

No, in "sideload mode" you can only apply updates via `adb sideload filename.zip`, no other ADB commands are available, except `adb devices` of course.

Just had a similar problem. Look at this: How-To Geek - How to Copy TWRP Android Backups to Your PC for Safe Keeping

In case you have TWRP installed or manage to somehow do so, then remember to take out the "Enable MTP" option in the "Mount" section of TWRP.

Title: Which app uses my GPS
I have discovered battery drain and it is caused by GPS but I don't understand how is that possible when my location is turned off and location permission is denied for every app installed and also any app I use don't need gps. I don't have any unfamous or pirated apps installed, and didn't get any new apps since 5 days, and problem started today. So is there any way to see which app is using gps since here is just blank name..?

Go to setting--\> Location

Then you will see list of recent apps who requested location. If you are still seeing apps there who is using location service then you can find which app is using your location service .

May be Google Play Services is the culprit here. It drains a battery a lot, infact it uses wifi scan in the background too!. So turning permissions off for it might help with the battery drain.

In the settings you can go to apps and there should be a menu where you can see which app has which permission, there you can click on location and you will see. Sincerely Rikvola

# Question
Title: How to recover my contacts
I accidentally deleted all my contacts from my phone. In my Google Contacts I was able to recover some of my contacts but how or where can I find the rest of my contacts?

# Answer
> 1 votes
If, you haven’t wiped your device completely, there is still a chance of recovering your lost or deleted contacts by checking if the old contacts database file is stored somewhere deep in your storage.

Depending on your manufacturer and Android version, you will find your database in different locations in your storage. For stock Android devices like the Nexus 5, the database file should be located here:

/data/data/android.providers.contacts/databases The key that your are looking for is providers.contacts/databases. To get to this folder straight from your device, install aSQLiteManager, which is able to get into your Android device’s database storage and open .db files.

If you can find this folder on your device and it’s empty, it means that your contacts are gone for good.

Well… Now it’s time to blast out a message to all your friends on Facebook, Twitter followers, business contacts and your family, asking them to send you their contact details. credit(Daniel) also check this link

# Question
Title: Copying files from PC to "external" SD card
I've got AirDroid and SSHDroid installed on a ZTE Axon 7 running 7.1.1. The phone has a micro SD card in it, and it can access (read from) that card successfully. What I *can't* do is copy files onto it. I can log in via ssh and see the file system, but I can't touch it.

I've had a Moto X Pure for the past year, and via SSHDroid and AirDroid I can readily copy files to the SD card.

Is this just a "security" (ie, "pay somebody") thing in the more-proprietary OS on the ZTE phone?

Obviously I can mount the micro SD card directly on the computer, but juggling those tiny cards is kind-of a pain. If there are other solutions, I'd be grateful.

*edit* — I've tried MTP with the Axon. I plug in the phone and tell it I want to connect as a "media device" with MTP. I then run `mtpfs` (I'm running Linux on the laptop; Ubuntu 16.04) and I get:

```
Listing raw device(s)
Device 0 (VID=19d2 and PID=0306) is a ZTE V790/Blade 3.
   Found 1 device(s):
   ZTE: V790/Blade 3 (19d2:0306) @ bus 2, dev 98
Attempting to connect device
Android device detected, assigning default bug flags

```

Then it just sits there. (I've never had much luck with MTP.)

*edit again* — ADB seems to work. I don't move files that much (mostly music and audiobooks) and while ADB is a pain it's easier than fiddling with the cards.

# Answer
If you're not insisting on a wireless transfer, using an USB cable would give you at least two options:

1. Using
2. Using

With MTP, on connecting the device to your computer you should usually get the option to open it in some file explorer (does so on Windows and on Linux at least). For ADB, you could use `adb push` to push files to your SD card – or, for your convenience, use an ADB GUI (some are listed here at my site.

For the latter, once connected via USB cable you could make it switch to TCP mode if you need it wireless. Without root, this must be repeated after each boot – with root, there are ways to initiate it without a cable.

Details can be found e.g. via the corresponding tag-wikis: adb and mtp.

# Answer
For those of you dealing with this problem on the **Mac**, install **Android File Transfer**.

This was by far the fastest and easiest way to get 30GB of data from my external SD card to my laptop. It can write to the card was well. This software is Mac only!

Title: What is the use case for the Google Wi-Fi Assistant?
The Google Wi-Fi assistant is available on the Pixel and Nexus devices running Android 5.1+, in some countries. The description at Settings-\>Google-\>Networking is

> Wi-Fi assistant: Automatically connect to Wi-Fi at select locations and other open networks determined to be high quality

Why would I want to use Wi-Fi assistant? I am not accessing anything on Google's network that requires authentication, and if an application requires secure data, it should already be using an SSL/TLS connection.

From a privacy point of view, this seems to trade the wireless network's ability to monitor all traffic with Google's ability to monitor all traffic through the VPN.

# Answer
The Google Wi-Fi Assistant is designed to provide a seamless always-connected experience using Wi-Fi. If, for example, you do not have a mobile data connection, the Wi-Fi Assistant will connect you to "high-quality" Wi-Fi whenever possible, and provide security through VPN.

Title: How do you securely delete android 6 phone?
Settings states that phone data is encrypted already, so do I just do a factory reset and that's it? Is this the same as a hard reset?

# Answer
> 0 votes
Yes, a factory reset of an encrypted device will wipe your device and delete the encryption key; it's a secure wipe (you can see some of the requirements here). If your SD card is not encrypted you might need to handle that separately — a full (non-quick) zeroing format from a PC should be sufficient if you don't want to reuse or destroy it.

A "hard reset" can either refer to a hard power off and reboot, or to a factory reset; obviously in this context it would be the latter.

What are the best 3D scanning mobile apps?

# Answer
In order to do true 3D scanning you'll need a phone or tablet with a depth scanning technology. Without it, the sizes and/or positions won't be correct.

Google Tango (was Project Tango) delivers 3D sensors in a mobile platform. You can see by this highlight reel Project Tango - Vision Summit 2016 what the technology is trying to accomplish: tracking in a room/indoors, geometry reconstruction, and various augmented reality overlays.

There are limitations like using infrared projector as part of the motion/depth sensing means that it works best indoors.

One phone, the Lenovo Phab 2 Pro is available, and another phone by Asus has been announced for a mid-2017 release.

Title: Google assistant custom commands
Is there anyway I can have custom commands for google assistant, which will show results how I want it to be?

# Answer
IFTTT now supports Google Assistant. You can create your own commands that interact with any of the IFTTT connected platforms. For an instance you can have a digest where you give notes to GOogle, and at a custom time every day you get those notes sent to you on email. Direct link to Google Assistant account with a lot of applets

As IFTTT interacts with all kinds of platforms, you have a large world of opportunities when it comes to creating your own commands. There are a lot of pre-made applets, including things like turning off lights, there is even one where you say "good morning" to the assistant, and it turns on a coffee machine

# Answer
From your updated description, you're referring to the 1st screen (sometimes called "splash"). It's encoded and built into a separate partition of the device (not `/system`), which can't be changed easily. Only on popular devices can devs bother to figure out the location and the format of the stored logo, thus making it accessible to us modders.

title: How to Disable Speed Dial?

text:
# Question
Title: How to Disable Speed Dial?
I have a Samsung phone, tracphone, with andriod 4.3.

talk back and explore by touch are both active.

When trying to use the phone, very short pauses are interpreted as a long pause, bringing up the speed dial dialog box. This makes it very difficult for a new smart phone user to make a phone call.

I did find the option to change the pause length on the device, but this is NOT a solution to the issue.

I have searched and am not able to find a way to disable or completely remove speed dial. It will never be used, so I am ok with completely removing it from the phone. Searching Google only returns results on how to delete or modify a speed dial number.

# Answer
> 1 votes
While this solution does not disable speed dial it does make the phone less sensitive to pauses, and makes dialing when talk back and explore by touch are both active much friendlier.

Suggestion by a family friend, worked great thank you.

Settings \> Language & Input \> Pointer Speed

Adjust the slide setting by touching the end of the slide (does not slide on our phone when talk back and explore by touch are both active.

On our phone, sliding to right (100%) significantly decreased the number of times the speed dial dialog box popped up.

title: What does "RF Cal" means?

text:
# Question
Title: What does "RF Cal" means?
I'm using Samsung Galaxy S5. When I entered in the dial `*#12580*369#`, it appeared some information about the phone. One of them is "RF Cal" (it is formatted like a date).

1. Does anyone knows what it is?
2. What does "RF Cal" stands for?
3. Where did this terminology come from? What organization/person coined it?
4. If "RF Cal" is the manufacturing date of the phone, then why not just call it the manufacturing date of MFD for example? Is it because there is a difference?

# Answer
"RF Cal" stands for "**R**adio **F**requency **Cal**ibration".

For smartphones, it means "time of first power up". After assembly, some parts of the phone (e.g. magnetometer & proximity sensor, radio chips, and antennae) must be calibrated before it's correctly functional. It is slightly different from "manufacture time" because hardware calibration is done after the device is fully assembled. You can simply think it's "time of the end of manufacture of this device".

I've been using one SIM card and one SD card for some months and now I need to use two SIM cards.

I need to stop using the SD card so I can use the slot for another SIM card.

My phone's memory can hold all data in the SD card as of today.

So apart from physical procedure to exchange them what I need to do with some apps data on it?

If you didn't used your card as internal storage using adoptable storage feature or apps like link2sd than you shouldn't worry about anything, you just pull out card. But if your photos, and some other files are on sd card and you need it on phone than you should transfer it to internal storage via some file manager. Only trouble you can get is that some apps requires sd card and they won't work I think that world of tanks is one of them..

Title: Change the actual kernel on my phone
After reading the "benefits" that I could have after changing the kernel of my phone I would change the actual one that my phone has. I've already flashed custom roms in the past and my question is if the procedure to change kernel is more less the same , so do I have just to flash it ?

# Answer
Yes the procedure is pretty much the same. Infact some custom roms already has the custom kernel inside them. Anyways if you want to flash a custom kernel, find one for your phone ( probably from xda-developers ).

If you found a kernel, if its already in a flashable zip, just flash it via recovery. Otherwise, put your phone in fastboot mode using button combination or via ADB by typing `adb reboot bootloader` and flash the kernel using this command `fastboot flash boot filename`

Note you need to have an unlocked bootloader for this to work and `adb` and `fastboot` working.

# Question
Title: Is it possible to simulate a gyroscope using the camera?
The title says it all. So, basically, I want to know if it would be possible to use the camera as a gyroscope, similar to how panorama mode works in most android devices. That's also the kind of quality I'd like. Not too impressive, and not completely horrible.

I'm not looking for alternatives. Don't suggest anything other than what I asked for.

Thanks for any help you offer.

# Answer
*Possibly*, but would likely require quite a work-around as the gyroscope is gravity-based and has more physical attributes. You would either need a sort of "reference point" for the app to use like a light source, but then you run into image recognition technology. I'm not much of a programmer, but if I was limited to just a camera, I would have the user calibrate the app first or at least the room they're currently in. It would go something like this:

```
Center your head, and keep it as stable and forwards as possible.

Now, look up when prompted on screen.

Now left,

Then right,

And down.

Now rotate your body 180° clockwise, or counter-clockwise.

Room calibration is now complete!

```

The issue you have with this however, would be that this would differ if the room changes, or if the user moves to another room. Something of this magnitude would be akin to taking a panoramic photo like you stated, but instead using the images as a reference for the app to know where the user is looking. This is quite a predicament. I would also take into account the *range* of quality in mobile cameras, as this will indefinitely have a substantial impact on performance. I also advise including a sort of disclaimer telling the user that their devices camera may not be up-to-par, or limit the apps availability to higher-end devices. Your best alternative would probably be an accelerometer, but it sounds like your aim is for a more common piece of hardware. Hope this is helps.

# Question
Title: Why is Google maps 48M on Android 4.4.4 and 125M on Android 5.1.1?
Why is Google maps only 48 Megabytes on Android 4.4.4, but is 125M on Android 5.1.1? The Android 5.1.1 phone seems to have a 32-bit processor and the 4.4.4 phone seems to have a 64-bit processor from devicespecifications.com. I would think the 64-bit phone would have the larger binary.

# Answer
If you have root access, you can browse `/data/app` and that's the difference.

```
# Sample for Android K 4.4
com.android.vending-1.apk
com.google.android.apps.maps-1.apk

# Sample for Android L 5.0/5.1
com.android.vending-1/
com.google.android.apps.maps-1/

```

And if you list the content of one of them, you'll see

```
com.google.android.apps.maps-1/:
base.apk (54MB)
lib/

com.google.android.apps.maps-1/lib/:
arm64/

com.google.android.apps.maps-1/lib/arm64/:
libcronet.59.0.3602.4.so    (4.9MB)
libgmm-jni.so    (9.4MB)

```

Also, Android 4.4 implements the old Dalvik VM, while on Android 5+, Google switched to a new VM called ART. The main difference is that Dalvik compiles apps Just-In-Time (JIT), while ART compiles Ahead-Of-Time (AOT), so more code is compiled in ART than in Dalvik. That's why this one is **really big**:

```
/data/dalvik-cache/arm64/data@app@com.google.android.apps.maps-1@base.apk@classes.dex    (109.5MB)
```

On Android 4.4 it's much smaller, you can find it out by yourself.

This seems to a problem with missing MTP drivers or which have not been installed properly.

Try this to resolve the problem:

* Press Windows key + X and go device manager ,
* Check if your device is visible
* Locate your android device, right click it and choose Update driver software .

Alternatively

* reboot PC
* enable USB debugging change from Camera mode to MTP then plug USB cable
* Now plug in USB cable, wait for MTP drivers to be installed (Don't cancel the windows which says "Device driver is installing, please wait...." )

* After successful install you can now access files in MTP mode

# Question
Title: How to confirm WiFi data is being used, not data plan?
How can I confirm that I am using data only on WiFi?

In other words, I am connected to WiFi at home and work, yet I get notices that I am close to hitting my data plan's max limit. Is there a way to somehow confirm that my data is being sent via WiFi when at home/work?

When connected to WiFi, even if the signal strength is say 1% of the WiFi connection, it's my understanding that my cell data plan will *not* be used until the phone disconnects from the WiFi, correct?

I know there's a way to see the amount of data sent over WiFi and the Data Plan, but I'm wondering if there's a way to somehow confirm that I'm on WiFi and the data is actually being sent via WiFi, and not using my data plan at all (*without* turning off the Data Plan in settings).

I'm just basically trying to confirm that my data is all going over WiFi, and not Data Plan, when connected to a WiFi Router (with any signal strength).

# Answer
I use a Galaxy S5 running Android 6 (Marshmallow) and my phone has different icons for wifi and data.

My phone also has little arrows that turn white if there are packets are being uploaded or download.

You can see data usage by app in the data usage setting.

And if you find that an application decides to use a lot of background without telling/asking you, you can click on it, and disable background data.

# Question
Title: Access windows shared folder via bluetooth
I have a specific requirement of being able to access a shared folder present on a windows 8 laptop. However, rather than doing this over the wireless connection, I want to be able to do this over bluetooth. So for example, if I have a shared folder on windows called Share and i drop a file in the folder called test.txt, I want to be able to see this file automatically updated on a folder called Share present on the android device, something like what dropbox does but just not over the wi fi. Any help will be greatly appreciated.

# Answer
I know this is an old as hell question, but I thought I would answer anyway.

Simply put, this is impossible with the way you'd want to implement it. Windows folder shares are SMB/CIFS, which is a NetBIOS/TCP/IP protocol. Bluetooth is, well, the Bluetooth protocol.

Technically speaking, you could use Internet Connection Sharing (ICS) on your Windows machine and connect to the broadcasting WiFi. You'd then be on your internal network, and you could access the share. But that would involve using your device's WiFi, not your Bluetooth connection.
> 1 votes

# Answer
I'm pretty sure it can be done although it is irrelevant for larger files. You just need File Transfer Profile (FTP), which comes with most Bluetooth suites. If its an older Bluetooth driver then you can find the Bluetooth FTP here: Bluetooth File Transfer (BlueFTP)

The received files are used store in Documents\Bluetooth
> 0 votes

# Answer
To add on to a more practical solution, this is a possible and can be achieved using this simple workaround:

You need a good file explorer for android capable of supporting network location folders.

In this illustration, I used ES Explorer. Also note your PC needs to support bluetooth browsing.

* First step, in the Bluetooth setting on PC allow bluetooth discoverability. See below:

* Secondly in your Android device be sure to switch on Bluetooth (pairing the two devices is preferred), open ES explorer, and go to Network \>\> Bluetooth, see below:

* Next tap on "Scan" and you should see your PC device like shown below.

* You will prompted by the PC to grant access to browse folders on PC and click "Allow", after that you can see the folders on your PC **through your phone** and file transfers are synced, and you just need to refresh to see the changes, (for example you can send a .txt to your Bluetooth exchange folder and see the changes in your phone)

Note: You can change your Bluetooth exchange folder in Bluetooth settings in your PC to any desired folder. I just used default

The post may be old but may assist those eho want to substitute ftp file transfers via bluetooth instead of Wi-Fi. Hope this helps

Google Play services and the Market (ie Play Store) should update themselves as long as you have a valid Google account on your device and there is sufficient space on the device. Try going here first to update Google Play Services manually and click Install/Installed button and select your device press Install. After it is successfully installed, reboot and open the Market app, it should open but don't do anything but close it, wait about 15 minutes and it should auto update to the Play Store and you are good to update/install apps.

# Question
Title: Android phone, recover photos or messages after factory reset, is it possible?
I recently bought an Android phone on a site similar to craigslist or ebay but more locally based. After buying it, I somehow got it into my head that the phone might be stolen goods. In hindsight, the price negotiation, periferals and seller history is what got me suspicious, though I must say I'm not a 100% sure.

The seller did a factory reset, obviously, it's what you do when you give the phone to a new owner, so that's not suspicious. But I was wondering, **is it possible to undo the factory reset** and recover any photos or messages, even is it's just partial, maybe this could give some clues to confirm my suspicions.

So I did a google search and there are many programs that claim to do this:

www.androidrecovery.com
www.recovery-android.com
www.tenorshare.com
7datarecovery.com
www.jihosoft.com
etc.

They all offer a program with a very similar GUI, the basic structure of them is all the same, so right off the bat that's a bit flaky and not very reliable. But I tried one anyway (jihosoft.com see here https://www.youtube.com/watch?v=5TdLzu\_Q2C4 ), which seems to install an Android app on the phone, does some more stuff, and in the end it just says "gallery(0), videos(0), audio(0)". So the program might actually work as advertised, but the previous owner erased the phone properly and thoroughly.

So my question is; Is there any way to (partially) recover photos or messages after a factory reset? Or maybe do some digital sleuthing using the IMEI nr?

Yes, you need root access for files other than pictures !

The particular method that doesn't require root access is only supported from Android 5.0.1+ ( i think )

You need to download Disk Digger ( photo recovery ) - rootless Disk Digger ( All file types, needs root ) I personally use Disk Digger Pro from Defiant Tech'

Google Store Link for Developer Defiant Technologies

Anyway i hope this helped.

Also,

• The Photo recovery doesn't need root access because it uses a new inbuilt photo recovery feature in Android 5.0.1+ devices

• The root access method will do an entire sector by sector scan on the internal storage, for the selected file types ... Several are supported.

Title: How to delete backups made using Clockworkmod?
Splitting this question from the comments to my answer to How to install ClockworkMOD Recovery on Sony Xperia Neo V (MT11a)?

> Erik, one last thing. I accidentally made an extra backup which didn't even complete because my SD is full, how do I delete that backup, or any other previously done backup using CWR?

Clockworkmod stores its backups in `/sdcard/clockworkmod/backup` (replace `/sdcard` with the path for your external card if you're looking for backups to external memory). With versions prior to 6.0, you can move off (or delete) the entire directory to clear space. The entire backup is self-contained.

If you're using a 6.0 or greater version of Clockworkmod, this is no longer the case. The information about the backup is still in `/sdcard/clockworkmod/backup`, but the actual data is now stored in `/sdcard/clockworkmod/blobs` and is deduplicated between backups. The upside is that this should save some space between multiple backups. The downside is you can't just move off or delete a backup directory. With 6.0+, you now have to delete that folder, and then run the "free space" option. Initiating a new backup will automatically free space.

If you are using a version newer than 6.0 I'd recommend you use the delete backup function in CWM.

It's in backup and restore -\> delete (and delete from external SD). Doing this will ensure that you don't delete a blob that is being used in another backup, as all backups now share the same blob directory.

After deleting from either place use the function recover free space from that same menú to delete the unused blobs

Clockworkmod stores Nandroid backups in `/clockworkmod/backup` on the SD card. Each subfolder contains one backup and is named with the date and time you created it. This is the same information that you see in CWM's restore menu. You can remove them from within Android with any file manager or from your PC while you have your phone attached via USB.

I had this idea: If you have CWM installed, you can delete (and make) the backup through the recovery mode. Go into recovery mode and select \- backup and restore \- delete from /sdcard then select the backup to delete done!

You also can do the backup through the recovery mode and ... there is an option backup to /storage/sdcard1 - I bet this will do the backup into the external SD Card. I haven't tried it, but i'm pretty sure it will do it.

you can't remove them with your pc -- they are write-protected. it only works if they're on the external SD.

# Question
Title: How do I send this explicit intent from Tasker?
This adb command from documentation causes a CAPTCHA to succeed in my favorite alarm clock app:

```
adb shell am start -n com.urbandroid.sleep/.alarmclock.AlarmAlertFullScreen --ez captcha_result_success true

```

I tested this command, and it has the expected result. However, I am having trouble achieving the same result from Tasker.

I use the "Send Intent" action with the following settings:

> Action -\> blank
> Extra -\> captcha\_result\_success:true
> Package -\> `com.urbandroid.sleep.alarmclock`
> Class -\> AlarmAlertFullScreen
> Target -\> Activity

Unfortunately, this doesn't do the same thing as the adb command above. The CAPTCHA screen opens, but it doesn't get dismissed. I'm not sure what is wrong. The Tasker documentation says that the colon syntax is how extra boolean variables are passed.

I've tried a couple of variations, but nothing has given the same result as the `adb` command.

The adb command is documented here: http://sleep.urbandroid.org/cs/documentation/developer-api/captcha-api/

# Answer
Here is how I fixed it.

> Package -\> `com.urbandroid.sleep`
>
> Class -\> `com.urbandroid.sleep.alarmclock.AlarmAlertFullScree`n

You must fully qualify the class and use the part of the package before the slash.

# Question
Title: Can I Flash Nexus Factory Image to any Tablet?
There are several different versions of Android ROMs on the Internet.

I found that no one is better than Nexus Android which is from Google.

There is a webpage on Google hosting every version of Nexus Android.

https://developers.google.com/android/nexus/images

Is it possible to flash Nexus images into other tablets like ASUS Transformer or Samsung Galaxy?

# Answer

No. ROMs are always device specific. Reasons are proprietary drivers for specific hardware components.

For more details, you might wish to follow up to the tag-wiki, tag-wiki, and the sites/pages linked from there, e.g. Is there an official Android “Google” ROM?

# Answer

The best answer for this question is you try flashing Nexus Roms on a old phone that you don't use.We cannot say that it cannot be possible without doing it practically.

IMPORTANT- please note that the old phone should be at least of 5.0 inch screen and the current Android running version should be Lollipop or above.

Please try it and reply me
