Title: Synchronizing phone numbers from android to gmail not working
I'm trying to sync phone numbers from my android (honor by Huawei) to my gmail account. I followed all the instructions, i.e. - I have my gmail account on the phone, I've gone to settings and enabled sync (including contact sync), it says that everything is synchronized but I can't see any of my phone contacts on my gmail (when I open it on my computer). Any ideas?

Google only syncs the contact which you save in google contact. The contacts saved in your mobile default contact library are not synced directly through the sync settings.

For synchronizing contacts in above stated case you need to use third party backup applications which provides services that include syncing of contacts to google servers and afterwards you can also get those contacts back to the device from google servers with the help of same application.

Such apps also provides the privilege to backup text messages, so they are worth trying.

First you need to copy all your contacts from **Phone Memory** to your **Google** account which you will want to sync your phone numbers to.

To do this,

> 1st =\> Go to **Contacts**
>
> 2nd =\> Click on **Menu**
>
> 3rd =\> Select **Settings**
>
> 4th =\> Under Advanced, select **Copy contacts**
>
> 5th =\> You should see a new pop-up window, (Copy contacts from), select **Phone**
>
> 6th =\> Select all the contacts you will want to copy to your Google account, if you want to copy all the contacts, you can simply click on the **Select all**

the moment you select the contacts you will want to copy, the **copy** option should be activated.

> 7th =\> click on the **copy**, after which it should prompt you where you'll want to copy to.
>
> 8th =\> You should find the Google account in the list of location to copy to. Select the Google account you will want to copy the contacts to, then you wait for a moment and all your contacts will be copied to the Google account.

To ensure that your contacts are in your Google account and they are sync, follow the steps bellow;

> 1st =\> Go to **Contacts**
>
> 2nd =\> Click on **Menu**
>
> 3rd =\> Select **Accounts**
>
> 4th =\> Select **Google**
>
> 5th =\> Select **Sync Contacts**. This should begin sync all your contacts, after you are sure that all your contacts are synchronized, you can now check your contacts on the https://contacts.google.com/ to find your contacts.

I hope this solves your problem.

# Question
Title: Encrypted SD card failed after S5 restart
As I can't get my Samsung S5 connected to my Debian 9.1 with KDE machine over MTP I had to use KDE Connect to copy over files.

I then had to move the files from my internal storage to the SD card.

I have both my internal storage as well as the SD card encrypted.

I copied over a lot of files which worked well. Then I ran KDE Connect for a bit longer to transfer a bit more files. I still have over 1 GB of free storage space on my internal disk. However my phone got stuck for quite a while: I could unlock it to see my wallpaper for a few seconds until it went back to the lockscreen (it had very slow reactions). I waited for a while and disabled the WLAN on my computer to stop any data transmissions which didn't help. I hence restarted my phone.

After restart I got greeted with the dialog to encrypt the SD card that said that SD card encryption has been activated and asking me to either enable it by proceeding or deactivating it. On the phone it shows no files on the SD card.

I connected it to my computer where I can see all the files which are unreadable (encrypted). I copied all the encrypted files over in case that helps me restore them and also wrote down the name under which the SD card was mounted.
I also deleted the "LOST.DIR" directory and a couple of files to free up some space in case that was the problem. I dismounted the SD card, reinserted it to my phone and restarted it.

The phone showed me that same dialog again. In searches I could only find questions where people had this problem after software updates or factory resets: but not after just a restart.

**Any ideas what might have caused this and how I could fix it?**

Note that it doesn't look like I can format the SD card. I could try pressing "deactivate" or proceed at that dialog. But wouldn't that change the decryption keys so that even if I copy my files back it won't be able to decrypt them?

# Answer
> 0 votes
**Solution**: Follow the steps outlined by Colbe here but format the SD card with GParted on the computer and then format it again on the Android. And leave out step 5.

**Likely cause**: a missing .MetaEcfsFile file.

Also GParted showed just the "boot" flag for the SD card partition: no "lba" flag.

# Question
Title: Using USB for transferring files (MTP or PTP) to phone or charging using USB
I had my Android phone power discharged fully. On fooling/trying to find the root cause saw the following as options in Android which I wasn't aware of before. This is in developer options though.

1. Transferring media files through MTP - This seems to be only one way from phone to PC and not the other way around :(
2. Transferring images or files through a PTP connection (guess it's a lower bandwidth connection)

Edit : Update - The target PC is running Debian Testing, not MS-Windows, sorry for not sharing that part.

3. Connecting MIDI devices
4. Charging.

What was surprising at least to me was you could choose only of the options and when one is chosen say charging the other options cannot be used.

Is there possibility of transferring media files through PTP from PC to phone or not anymore ?

Also were these options always part of android say 5.0 or it's a new development in 6.0 marshmallow ?

# Answer

Its a new development in android 6, mainly the location of these options. The USB configuration of Android 6.0 marshmallow is slightly different than other versions.

> In Android 6.0, the options seems to have disappeared. It has in fact moved and you can only access it if you’ve enabled developer options.

The first option is to have a “Charging” only option which can be used to connect to a USB port to charge the device without any notification to the computer. This will be the **default** option for the device and hence the device will not allow to access the files unless it is explicitly changed.

**MTP (Media Transfer Protocol)**

When Android uses this protocol, it appears to the computer as a “media device.” A standardized protocol for transferring audio files (and other media) to digital music players using Windows Media Player and similar applications.

You can transfer media files either way.

> Android can choose the files it presents to you, and hide system files so you can’t see or modify them. If you attempt to delete or edit a file that can’t be modified, the device will refuse the request and you’ll see an error message

**PTP Picture Transfer Protocol.**

When Android uses this protocol, it appears to the computer as a digital camera.

> MTP is actually based on PTP, but adds more features, or “extensions.” PTP works similarly to MTP, and is commonly used by digital cameras. Any software program that supports grabbing photos from a digital camera will support grabbing photos from an Android phone when you select the PTP mode. PTP was designed to be a standard protocol for communicating with digital cameras.

It is generally recommended on a modern Android devices, to use MTP rather than PTP unless you have software that only supports PTP.

*Note: It has been noted that you may need to physically remove the SD card after upgrading to Android 6, and putting it back in before you can view the files on your PC*

If you're having issues transferring media in your upgraded OS, try troubleshooting using these options:

1. Make sure you have installed appropriate drivers

* Connect your device to your PC and wait. If it doesn’t show up in file explorer, check to see if Windows is searching for drivers.

If it is, allow it to search and install any drivers it needs. This can happen even if you have connected your Android device to your PC under the same connection type. Do not disconnect the device and allow Windows to finish installing drivers.

2. Fix corruption issues on your external storage

* Use an sd card adapter and insert in the slot on your PC, right click on the external storage device and go to properties, tools then **check for errors**, fix if necessary the re insert it in your device and check if problem is resolved.

# Question
Title: Google Photos app stuck on "Getting ready to back up"
I've been using Google Photos backup and sync for years without problem until yesterday. It is stuck on "Getting ready to back up" for a day instead of "Backup complete". Any suggestions how to resolve? I can't tell which photo it's stuck trying to sync, I don't see the "circular arrows" on any of the photos.

I've already tried:

* Restarting the phone
* Force stop the app
* Clear app cache
* Clear app data
* Free up space (delete device photos that are already in the cloud)
* Remove active Google account from Google Photos and re-adding it.
* Verified that I am running latest version of Google Photos app.
* Verified that I still have 16 GB left in my Google storage.

I am using:

* Google Nexus 6P
* Android 7.1.2
* Google Photos v 3.4.0.167082928 (updated on Sep 1, 2017)
* Upload size: Original
* Wifi only (does not have SIM card)

# Answer
> 1 votes
First, try all of the steps listed in the original question. If that doesn't resolve the problem, then the issue could be that your device and cloud Google Photos are out of sync in an unrecoverable way, and you will essentially have to do a manual sync.

Confirm that your device is out of sync with cloud:

* In Android Google Photos, do `Free Up Space`. This will delete all the local photos on your device that have already been synced to cloud Google Photos.
* Now go to `Android Google Photos > Device Folders > Camera` to look at your local photos remaining. If Google Photos is synced, there should be no photos here. If you still see photos, that means it is out of sync.

If you have determined that your device is out of sync with cloud, then you need to manually sync your device's photos.

* Open cloud Google Photos on a desktop browser: https://photos.google.com/
* Compare the Android device's local photos with those on photos.google.com
* Connect your Android device to your computer via USB cable (you may need to enable MTP transfer mode)
* Copy the photos/videos from `DCIM/Camera` to your computer.
* On the computer, upload the photos/videos to photos.google.com
* Confirm that all the Android device photos show up in photos.google.com
* On Android device, delete all the photos in `Android Google Photos > Device Folders > Camera`

Now the Android device and cloud Google Photos should be synced up, and you should not see the "Getting ready to back up" message.

# Question
Title: Smart Lock unreliable/not working with NFC tag?
I’ve been trying to get Smart Lock to work on my Android device (OnePlus One on Cyanogen OS 13.1.2, i. e. Android 6.0.1/“Marshmallow”). I’ve configured an NFC tag as a trusted device and want to use this NFC tag to unlock my phone instead of having to type my long password every time.

The problem is that unlocking using the NFC tag is really unreliable. Most of the time, when I activate my NFC tag on the lock screen, nothing happens, even though the pulsing circle around the lock icon at the bottom of the screen is present (indicating that Smart Lock is active). Sometimes, however, the NFC tag is recognized and unlocks the phone without problems. I haven’t really figured out the circumstances under which it happens. For example, when I turn NFC off and then on again in the settings and lock the phone then, unlocking using the NFC tag once always works without problems, but the next time, it won’t work again.

What could be the issue here? Am I somehow using Smart Lock incorrectly? Does Android perhaps turn off NFC or the process responsible for Smart Lock after a while when the phone is locked (Doze mode)? If so, how do I prevent this?

---

*Note:* Also tried on someone else’s phone running Android 7 (“Nougat”), same thing: after setup, unlocking the phone using NFC works exactly *once*, but immediately locking the phone again and then trying to unlock doesn’t work.

This is a known issue, https://productforums.google.com/forum/#!topic/phone-by-google/DyxZwJpsOwY & https://issuetracker.google.com/issues/62268615.

In addition, the NFC Smart Lock feature has been removed from 7.1.2 (I think that was it) and is still gone in Android 8.0.0 Oreo.

# Question
Title: Why can't I hear callers after installing new upgrade?
I was notified on my phone that it had an upgrade so I selected it. Now no-one can hear me unless I put it on loudspeaker although I can hear them?

# Answer
There is no guarantee, but **hard reset** most time tends to fix this type of problems, try and observe your phone closely, you might have some apps that might be manipulating the speaker in your phone. Take time to troubleshoot the problem.

If there's no app causing the problem, then you can run a **Factory resetting** for your device by following the steps,

> 1. click on your **menu list**
> 2. **Settings**
> 3. **Backup and reset**
> 4. click **Factory data reset** which usually should be at the end.
> 5. **Reset phone** or **Reset device**.

Ensure you have adequate charge on your battery to handle the entire process and that battery is not mistakenly pulled off during the process, because if any happens, it can lead to corrupting of data.

# Question
Title: Android AVD not displaying appropriate scale
How do I fix the display on my android AVD? The UI is completely out of whack. I'm using the following command line options to launch the AVD, but nothing I do within the 'scale' and 'dpi-device' options helps fix the messed up display (see example screenshot). I'm running on Arch Linux with the latest Nvidia proprietary driver 346.35. Any help is greatly appreciated.

Command:

```
$ emulator -verbose -scale 0.9 -dpi-device 480 -noaudio -no-boot-anim -noskin -no-snapshot @lollipop -qemu -m 1536 -enable-kvm

```

Also, according to this StackOverflow post, I also did:

```
$ adb shell setprop qemu.sf.lcd_density 480
$ adb shell stop
$ adb shell start

```

Doing this has made no difference to the messed up display on my emulator.

Note that I have to use the `-noskin` option because it refuses to launch the emulator for me otherwise.

# Answer
I don't launch from the command line, but this question came up while I was trying to solve a similar problem.

I eventually solved it by replacing the `hw.lcd.density` value in the `.android/avd/<avd_name>.avd/config.ini` file with the value from this answer nearest to the value in the skin's `hardware.ini` file (in my case that's at `<android-studio-location>/plugins/android/lib/device-art-resources/<skin-name>/hardware.ini`).

In my case, I'm emulating a Samsung Galaxy S6, and the Samsung provided skin has an `hw.lcd.density` of `200`, but the dimensions they provide are `1440x2560` and the provided background images are small, so they make the screen fit into a much smaller space (`474x839`), so the `config.ini` file has a `hw.lcd.density` value of `640`. Decreasing it to `213` and restarting the emulator fixes the problem (but I guess it doesn't quite accurately emulate the screen appearance. I don't know whether it's better than just using a different screen resolution value).

# Question
Title: Battery draining extremely quickly Galaxy S7
My phones battery was draining extremely quickly a few moments ago, around 1% per 2 seconds. It's been doing this fairly often but when I go to **device management and clean everything** it usually stops draining.

This time though, the battery kept on being chugged and I couldn't find any explanation as to why it would get drained like that, everything was asleep or off. Even after **turning off and on my device**, the battery kept going down and the phone kept getting hotter and hotter.

Would any one know what else I could do? I feel as though I tried everything possible.

(in case this happens again since it randomly decided to stop chugging.)

Thanks,

to note:

* Device software is up to date.
* Device is 1 1/2 years old.

# Answer

This has being a common problem with S6 due to update to marshmallow, I believe this should also work for your S7.

Wipe your phone **cache** or **system partition** by following the steps below;

> Go to **Settings**
>
> **Storage and USB**
>
> **Cached Data**
>
> **OK**. This should wipe your system partition.

Or you can also do the same thing from recovery mode by following the steps bellow:

> * Turn off your Galaxy S7.
> * Press and hold Power
> * When ‘Samsung Galaxy S7’ appears, immediately release the Power key and then press and hold the Volume Down button to access **Fastboot**
> * Use the volume buttons to highlight Recovery and press Power to confirm.
> * If you see the Android robot, press Power, then Volume up briefly to access Recovery.
> * Scroll down to Wipe cache partition and hit Power to confirm.
> * Scroll down to Yes and hit Power to confirm.
> * Reboot

If the problem persists, you can also clear the app cache for your device and the last resort is to do a full backup and perform a factory reset. Wiping your device and restoring your apps and data is one of the simplest and best ways to avoid any weirdness battery drain and general system performance issues.

# Question
Title: Building LAN with android phone (Xiaomi Redmi 3s)
I am trying to build a LAN using my phone. Have connected the phone via USB to the pc and switched on WiFi hotspot (so i can connect laptop, printer etc to the Internet). But i cant get them together, as i know my public IP provided by IPS, i cant get the local IP for my PC, and other gadgets as well. And my phone is not connected to any WiFi hotspots, as i use it as a hotspot itself.

# Answer

If you have more information, I can help you. The APP ES file explorer provides a LAN function. If you want to route over the PC to a router or something do this.

1.)First, you need to enable routing.(Windows)

2.)You need an app that provides you with a terminal (terminal emulator etc.)

```
Example:
ifconfig usb0 192.168.0.2
route add default gw 192.168.0.1

```

Set your DNS server :

```
echo "nameserver 8.8.8.8" >> /etc/resolv.conf

```

or with BusyBox:

```
nano /etc/resolv.conf

```

3.)Under Windows you need to configure the path to your router.

```
route ADD 192.168.0.2 MASK 255.255.255.0 192.168.0.1

```

Title: How do you disable "add icon to home screen" on Android Oreo?
On Android Oreo, the option for "add icon to home screen" is no longer in the Play Store settings. How do you disable the option?

# Answer
> 47 votes
I've been looking all over the internet for an answer to this for a while. In hopes of alleviating other people's headache's, here's how to enable/disable automatically adding home screen icons of newly downloaded apps in the newly released Android Oreo.

You won't find the setting in the Play Store anymore, nor is it in the Google app settings, or the device Settings. Instead:

1. Hold on the home screen
2. Tap Settings
3. Toggle "Add icon to Home screen"
4. Rejoice in knowing you didn't search for this for over an hour

Note that this fix is confirmed for the default Android Oreo launcher, tested on the Pixel. Other launchers and devices may differ.

# Question
Title: How can I enable Wi-Fi calling only when I'm at home?
I have a phone running Android Nougat. I live in location with poor cell service, so I'd like to use Wi-Fi calling at home. But I want to use cell service for phone calls everywhere else, especially when I'm at work or connected to a public hotspot with questionable bandwidth. Is there a way to automate this?

In the Wi-Fi calling settings, I can tell the phone to prefer Wi-Fi or cellular, but it always uses the preferred service if it's available, even if the quality is terrible. So I'm hoping for a solution that automatically enables or disables Wi-Fi calling based on location or network name.

# Answer
This app does more or less exactly what you want.

You can create rules for entering and leaving an area. You could, for example, if you are at home simply switch off mobile data and connect Wlan.You can also connect the rule with your reception quality, try what works best.

Title: Any way to stream YouTube sound off of Nexus 7 to Yamaha amp over Airplay?
I have the following 3 devices:

1. a Nexus 7
2. an iPhone 4s
3. a Yamaha RX-473, which supports airplay

All are hooked up over my wifi. I've setup Airplay with the amp and the iPhone, allowing me to watch videos on my iPhone and hear the sound out of the Yamaha amplifier, but I'd love to use the Nexus 7's larger screen to watch youtube videos.

Is there any way to wirelessly stream youtube audio from my Nexus 7 to my Yamaha receiver, in the same way that I can using my iPhone?

No there's no way you can search into a specific channel on YouTube. Basically YouTube does not provide that privilege.

But if you are considering a specific channel and want to search videos related to the channel only than you can perform relative search which includes the basic search attribute with the channel name. By doing so your search results will be narrow downed and you will find easily what you wanted.

For example:- If you like Luis Fonsi vevo channel and want to search within his creation than try something like this:- x+Luis Fonsi vevo(where x=your basic search attribute.)

You can use the YouTube Channel Search (web app) to search videos within any specific channel that you are subscribed to. (Disclosure: I created this app)

# Question
Title: Turning off mobile data: method used to work but now doesn't
On my old phone I used to turn on mobile data when I wanted to check emails... but I would often forget to turn it off afterwards. To fix this problem I installed Macrodroid and programmed it to turn off mobile data every time the screen turned off. This was my perfect solution and was very happy with it for years.

Now I have a newer phone (Android 5.0.1) and was very sad to see that with this version of android it appears that Macrodroid can no longer turn off mobile data. This now means that when I occasionally forget to turn it off manually I can use up a ton of data. Now you might say "no worries, just set a mobile data limit" - but this does not solve the problem at all - it may mean that I won't go over my limit but that's of little comfort when it means that I have used up all my data and can not use it again till the next billing period.

Is there any other way to manage my forgetfulness?

By the way I know that macrodroid can control mobile data if the phone is rooted - but my banking app, which I use regularly, detects a rooted phone and refuses to run.

# Answer
It is possible to toggle mobile data **without root**, using Tasker and AutoInput plugin.

**Important**: This feature requires screen to be on. (Some users report that it only works if screen lock security is set to none or swipe.)

You need to perform two tasks as follows:

* A1: Go to new action \>\> Plugin \>\> AutoInput \>\> Unlock screen
* A2: Net \>\> Mobile data \>\> \[Set Off or toggle (whatever you wish)\]
* Exit to save Task

**Note**: AutoInput also emulates user swipes on the screen, which means that you can pull down the notification menu and then toggle whatever you want, including mobile data.

Create a condition/profile that suits your needs.

# Question
Title: how to save you tube videos from the library onto my computer
I have saved YouTube videos from my android phone into the YouTube library. I thought it was being saved onto my phone.

How do I save the videos from the YouTube library onto my android phone or computer?

# Answer
The videos that you download in offline mode on your mobile YouTube app are saved on your device only but their extension is different and therefore they cannot be played except official YouTube application.

If you want to view the downloaded video somewhere else on your device rather than YouTube app than you need to download third party application called 'Tubemate'. Tubemate is the right choice to download YouTube videos in desired resolution. Also it gives users privilege to download videos from other sites like 'Dailymotion', 'Vimeo' and many more. Tubemate directly saves the video on your default memory location whether its internal storage or sd card.

For computer the best application used for downloading is 'IDM'. Download and run the setup according to the instructions and afterwards integrate IDM integration module extension in the browser. That's it, you are ready to go from there. Visit YouTube from the browser and when you play the repected video, direct download link through IDM will be generated. Click on that and enjoy your downloaded video whenever, wherever, however and on whatsoever platform you want.

Title: How to send sms to all contacts in Android 6?
I need to inform all the contacts with mobile numbers in my contacts list on my new mobile number. How do I do that?

# Answer
Most stock messaging apps are not able to do this... if it does, create a new message and go to groups and select All Contacts.

If it does not have that capability, there are several alternative apps in the Play Store that do have that capability, such as Textra SMS, Chomp SMS, Handscent Next SMS, or most other 3rd party SMS/MMS apps are capable of this as well.

Note that in Android 6 there are some permissions involved and only one messaging app can be active at a time, so you would have to install the new one, give it permissions to be the default messaging app, send your group message, then change the default messaging app back to the native one that came with your device if you wish. Although, depending on your stock messaging app, you may find a 3rd party messaging app much more feature rich and you can safely leave it as the default.

# Answer
If you are using the stock Messaging app... I mean the Google one, go to its setting,.. You should find an option for sending a single message to multiple contacts as MMS. Uncheck it and you are done

Title: Restore messages from old whatsapp file
i need to restore old messages from a year and a half ago that i have the files of but everytime i load it onto the phone it does not load those messages, can anyone help me? it is also no longer the same phone... S5 to S6

A year and half? I don't think you can do that because WhatsApp changed the encryption system of messages a couple of months ago.

Below is my WhatsApp message backup.

# Answer
> 0 votes
I don't know how to put it. But I realized something. My friend and I used to exchange phones. At one time after i use his phone and remove his WhatsApp account to mine, though different numbers, WhatsApp gives me the option to restore backup from drive or SD. When I skip the drive and choose SD, it restores my friend's messages and media to my account and they are visible.. So I think if you have the backup file you can put it in the right WhatsApp directory and get everything going

Title: insufficient storage - df - sufficient conditions?
I know there're lots of questions about insufficient storage, but no real answer so far ! In particular about /data/app, which has plenty of space in my case. So why can't I install any new app ?!

# Answer
There's a related thread on XDA describing a work-around. Adapting it a little so you don't need that "specific tool" (LP):

1. Set the install location *explicitly* to internal storage:

```
pm set-install-location 1 # (0=auto (default), 1=internal, 2=SDCard)

```
2. Clear the Play Store settings

Now your install should go through.

As the comment in the code line shows, by default Android is set to automatically chose the storage the install should go to. It seems something is messed up in that evaluation. So by making your wish explicit, that "auto evaluation" routine is skipped, and thus the error avoided. If that's what's behind the issue, it should work as well setting your preferred storage to `2` (SDCard) if you prefer that.

Reading your comment, the culprit might have been a little different at least in your case: If you had set the install location to `2` and then removed the card, it's pretty much clear why there's "insufficient storage" on the empty slot :)

Title: Touch screen acting weird (P9)
I recently got a new touchscreen, which seems to work (since you can see the touches in debug mode), but sometimes it just won't swipe from one page to another! This also happens in an app. What is wrong, I don't get it?

Video: https://puu.sh/xtaow/ed633e8833.mp4

PS: When swiping slower it sometimes works better, but not always. PPS: When having the phone in my left hand, I can only swipe right and vice versa. When having the phone on my table everything works perfectly.

title: Remove Phh's superuser?

# Question
Title: Remove Phh's superuser?
I have TCL Alcatel Pixi 4 (5) 5010D phone that i bought and decided to root it. I was kinda new to this kind of rooting (a bit complex) because i used kingroot before and it worked just fine till i got this phone and no app for rooting helped me which lead me to rooting using my computer.

I've searched on google and found one thread on XDA by kirito9, showing his tutorial on rooting Alcatel pixi phones and i've found mine there. Multiple choices occured and i couldn't decide which one is easier for me. So i went on to try phh's superuser method. Everything went fine, i've got TWRP installed on my phone and flashed phh's superuser onto my phone, rebooted and... well it booted fine. Installed the required superuser and Titanium Backup. Superuser worked fine and so did Titanium Backup.

Later i decided to uninstall some system apps that i didn't need and were wasting space so i downloaded system app remover and allowed root access.. as soon as i tried to uninstall the app, my device rebooted. I thought that was a normal process but i saw that the app did not uninstall. Tried again, same thing. After doing some research, found out that i don't have access to rewriting /system and files in it at all. I tried downloading an app again to make /system rewritable, but no access. Then tried it through ADB but didn't work as well.

So not sure but i think that's half root which i don't want, i wanted full root but i didn't get it. Now i wish to remove this phh's superuser and trying to get root another way if i can without bricking my device and of course, making /system rewritable so i can uninstall useless apps. Can't even install busybox because of this. Would appreciate help on both uninstalling phh's superuser and getting another method of safely rooting my phone.

# Answer
You should try this using es file explorer. In the dash board of es file explorer, go to tools then turn on the switch for root explorer. After that consider turning recycle bin on for later restores. Next tap on root explorer and a subwindow should open . Select Mount R/W. That's rewrite permission. Still there, you can select uninstall system apps. It should work well. Proceed with caution and at your own risk

title: Xiaomi Redmi 2 Pro Battery Issues

# Question
Title: Xiaomi Redmi 2 Pro Battery Issues
I have a Redmi 2 Pro, and it works fine, except for some issues with the battery. If I charge it to 100% before I disconnect the charger and go to sleep, by the morning it may go down only to 98%, but if I leave it on around 70% for the night it can even shut down by the time i wake up. In every case I use CleanMaster to shut unnecessary apps down before I go to bed. The possible shutdown makes it completely unreliable when it comes to morning alarms.

One solution may be to leave it on charger for the whole night, but i heard about it being damaging to the battery. Is it? What can i do?

# Answer
> 1 votes
Based on the information provided, it appears that the problem could be due to any of the following factors:

1. **Weak/Dying Battery:** Can be verified by changing the battery
2. **System not going to deep sleep:** Could be due to wakelocks letting the system alive either from apps or system like media server. Clean Master may say that it had killed apps, but it cannot kill apps completely , including background processes unless it has root capability and is designed to do so. Neither does it ask for root permissions nor does the app description claim it can kill background processes, so one cannot trust that it is really killing your apps

I would first suggest that you do a factory reset after taking a back up of your data. I am presuming your device is not rooted, so you can see this for taking a back up Full Backup of non-rooted devices. This solution does not cater for SMS, contacts/ calendar which can be done using CM backup

Instructions for doing a factory reset for your device here. If the problem persists after factory reset, then I would suggest you to change your battery.

I am hopeful that this should resolve the problem. Please revert with Irvine and edit your question with additional information sought in the comments section, which would come in useful if the problem is not resolved

Coming to your other question, leaving it on charger overnight is **not recommended**, since the Battery gets internally hot and stress caused by this reduces battery life as you can read Find out how to prolong battery life by using correct charge methods.. Related inputs for additional reading Should I charge phone overnight or let battery down to a minimum?

**Edit**

Are you on MUI 3.6.6.0? Asking since rapid battery drain seems to be a problem , unresolved till mid last year, as per reports here

In any case, your device has the facility to identify battery consumption separately for hardware and software (app wise) as shown in screen shot below taken from the same source. Can you study that to identify the culprit, in case of rapid drain? You can quickly weed out the battery hogging apps using this

# Answer
> 0 votes
I can say one thing based on my experince.. i have a samsung galaxy tab 3. I had these issue.. below 70% the battery has some kind of wierd problems. I was using some apps that claims to free memory etc like clean master, 360 security, battery saver etc. I dont know specifically what i used. But that was the reason. Android has inbuilt ram and battery management. These apps doesnt do anything but harms. They take huge space in memory and drains battery faster. Better delete such apps and check your battery..

# Question
Title: How to change icon shape in Android Oreo 8.0
Recently updated my Google Pixel to Android Oreo 8.0. I can't find the "change icon shape" option. Where can I find it?

# Answer
Since you did not mention the developer preview version. Assuming you are using dev preview 1.

The newly added menu that’s available on the **second developer preview** of Android O contains a **“Change icon shape**” option on the main **Settings** screen that’s located near the bottom of the interface, immediately above the “About” section. Tapping that option prompts a pop-up window from which you can choose the shape.

# Question
Title: Disabling animation of the Wifi connection icon
On Android 7.1 the wifi icon does not only show the signal strength by the well known circular four bar image, but also underneath it there are two tiny arrows, one pointing up and the other one pointing down. They are used to indicate correspondingly the activity for the upload and the download. This feature although seems cool at first can be very distracting at times, when you read for example. My question is can you disable the animation? Ideally just remove two tiny arrows and only leave out the curved signal bars just like it looks on iOS for example.

# Answer
You cannot just tweak the arrows from the UI. But you can disable the notification icon.

Since you’re on Marshmallow, first enable System UI Tuner by long pressing the Settings icon in the pull-down notification shade for 5 seconds. Then go to

`Settings->System UI Tuner->Status bar->Disable WiFi.`

Done.

# Question
Title: Apps offering free data or money based on using and sharing
I have been hearing about some android apps which give you free money or data by installing, using and sharing. Many of my friends have been asking me to install such apps so-that they get benefits of sharing app with trying to convince me like "share to others and get free benefits". Such apps also gives benefits if you install other apps or click on some links through them.

But I've been refusing to install or use such apps thinking following reasons:

* It should be nothing but pure advertising app for app maker
* It may get our personal information like email, phone, contacts and even some may get usage and information of other apps, files etc.

But/Now, I want to know more about such apps like how do they work? what are the major and possible disadvantages (malicious, spy etc.) of using such apps, etc. so that I can keep way from possible temptation/seduction and can preach my friends with better understanding.

# Answer
Your concerns are 100% valid!

A few things you can consider while making a decision whether to install such apps:

-Firstly, do you really need this so called app? If not, don't install!

-Secondly, see if the app has any good/social cause which really helps people if you download the app (when i say help, i dont mean your friends getting free money), if it does, then consider helping out!

-Lastly, if you do choose to install the app, check the permissions the app is asking before installing. Try not to download from unknown sources, and do read the reviews. If you have Xiaomi phone or cyanogenmod/lineage, they usually have 'App Permissions' sections, make sure not to give the application any permissions!

# Answer
Your concerns are right. Never trust "free" apps, gifts or something else like that, because those companies always will make their profit otherwhise they wouldnt exist. Most of those apps are pure fake and some even harm your device by later install malware payloads on your Smartphone.

How may i install an app, and have the "startup configuration screen" (where the user selects his language, google accounts, etc) without doing a factory reset?

# Answer
You can make that app an system app that will prevent your end user from uninstalling this app and even after an hard reset the app is still active, plus the app is installed before the device is given the end user.

ps you must modify the system for that which will mostly cause a loss of warranty.

title: Encryption state after changing PIN

# Question
Title: Encryption state after changing PIN
I enabled device encryption but android didn't gave me the chance to choose a new password instead it used the lock screen's. I came back to screen lock settings and changed the password and encryption password has changed automatically. But that happened instantly, my device didn't go through any process of encryption

Question is: Does changing encryption password require any kind of long re-encryption process? In other words, is my device still secure and data is encrypted securely?

Device: Xperia E4 Dual

Android version: 4.4.2 sony stock

# Answer
From the Official Android Source:

> Upon first boot, the device creates a randomly generated 128-bit **master key** and then hashes it with a **default password** and stored salt. (The default password is: "default\_password").
> However, the resultant hash is also signed through a TEE (such as TrustZone), **which uses a hash of the signature to encrypt the master key**.
>
> When the user sets the PIN/pass or password on the device, **only the 128-bit key is re-encrypted** and stored. (ie. user PIN/pass/pattern changes **do NOT cause re-encryption of userdata**.)

What this means is that, essentially, there are **two keys** to be understood:

1. The master key
2. The user\_encryption key (or just 'key')

The master key is generated during the first boot only, and never ever changes (unless maybe a factory reset or wiping userdata partition is done). The data in the /data partition is encrypted or decrypted only using the master key. The master key **cannot be stored as it is** (it's not safe to do so, right?), so it is encrypted using another key said below.

The user\_encryption key is the key using which the encrypted master key can be decrypted, because only using the master key, the encrypted data can be decrypted. (This key is computed based on your PIN/password/whatever.)

People often tend to think both these keys as one and the same, which is not the case here.

When you change your unlock PIN/password, only the user\_encryption key changes, not the master key, so the data is not re-encrypted.

# Question
Title: Any other way to recover system?
Past days my android phone got in bootloop. Since I didn't have access to PC, I tried some things from recovery. Tried to format dalvik-cache, but it failed because it was r/o. I tried installing SU, trying it again, remounting it as r/w but no success. Then I tried to backup and wipe data and system, then recover (stupid). I discovered that TWRP breaks everything when formatting. It broke data and system partitions and they were no longer mountable, I tried like 10 times reformatting them with no success. Then I decided to format Internal Storage (again stupid) and did it. Guess what? TWRP broke Internal Storage. Now I ended up in this: No recovery, no bootloader, no boot logo. Just black screen and vibrations indicating bootloop. Is there any way of recovering without service center?

# Answer
You can install TWRP again (if you dont have it) and try that:

goto: wipe\>advanced wipe\>select one of the broken file systems \>press repair or change file system\>repair file system

if that doesnt work:

goto: wipe\>advanced wipe\>select one of the broken file systems \>press repair or change file system\>change file system\>ext4 or the file system that your rom initialy supports

then: reinstall your rom

There is an application through which you can control the screen over **USB** and **adb** called **ADB control**. Follow the link to install and use it. Then you backup contacts to your phone/google account once you have control.

Do you have USB debugging enabled on your device?

Droid@Screen allows seeing the screen output and also interacting.

# Question
Title: How can I verify my phone's Bootloader, OS, and ROM haven't been tampered with?
I just purchased a Galaxy S7 for a really cheap rate... and it makes me wonder if the phone has been hacked in some way.

I know the phone supports Samsung Knox, and am new-ish to Android overall.

**Question**

* What can I do to verify if this phone was untampered with?
* How can I reset it (restore ROM?) to a known-trusted state?
* Is there a general process for all Android phones, or is the verification method and technique manufacturer-specific?

Would love to know about any notable Android hardware security solutions (I already researched Blackberry Priv and Samsung.)

# Answer
There are a few indicators of modified/unmodified devices, depending on what was modified and how.

Depending on the manufacturer and model, some of these indicators are not available.

These should apply to any recent Samsung phone:

1. : Go to `Settings` -\> `About phone` -\> `Status` -\> `Device status`.
As long as the ROM/firmware hasn't been tampered with, it should show `Official`.
This can be Official, even when using custom ROMs, so it's not the best indicator, but the easiest to access.
2. : Hold `Volume-Down`+`Home` when powering on the device to boot towards the bootloader (used to install official and custom firmware, recoveries etc) and press `Volume-Up` without connecting it to a PC (just to be sure).
It will show some information about the state of the device like
the binary status ("Custom" means it's modified), the system status (I rarely seen this not reading "Official")
or KNOX warranty void status (just voids any warranty around KNOX, not anything else; hardware warranty and non-KNOX software warranty is still valid) that indicates tampering with the system at *any* point in the past (not even reinstalling an official firmware will reset this).

Devices which utilize `fastboot`, can be queried using the `fastboot` command (from the Android SDK, but there is a package with only the required files).
The command should be `fastboot flashing get_unlock_ability` (not tested, I don't have a device with fastboot capability).
> 3 votes

# Answer
Just to be sure you can simply download stock firmware for your phone model and flash it, if someone has played with something it will be gone. (Not sure about bootloader lock state, on some phones it reverted back to locked but on some doesn't).
> 0 votes

# Answer
Turn off your phone then press volume down + home button + power a warning screen appears press volume up

WARRANTY VOID should be 0. 1 means the system was or is an an NOT official feature, but if the current binary & system status show official everything should be safe.

After that you can run an antivirus scan with the built in Virus scanner

# Question
Title: Google Play Store Hangs at Every Step
This week, the Google Play Store is behaving very strangely. It can download *or* update a single app but not both without being killed!

There was an update for Chrome this morning, so I went to Google Play Store and clicked on the *Update* button. It then downloads the app, reaching 100% pretty quickly and hangs there forever, OK well I let it do that for an hour or so (but tried overnight with previous updates). Then, if I *Force Stop* the *Google Play Services* and restart it, it automatically does the install in a few seconds. If I try again to update another app, it downloads to 100% and hangs.

This very strange. Up to last week everything was working fine and no new apps were installed but there was about 9 or 10 updated. Since then, I must download and update one at a time, killing the Google Play Store between each!

Versions involved:

* Android 7.0 Kernel 3.18.31 Build NPP25.137-76
* Phone is rooted, has been for over a month.
* Google Play Store 8.1.30.S-all
* Google Play Services 11.5.17 \[UPDATED\]
* Google Play Services for Instant Apps 1.20-release-166886311 (WTH is this?, don't remember seeing it before)

How can I fix this and have Google Play Store working normally again?

Used to be able to install and update many apps without killing the Google Play Services.

Title: How does drive droid work?
I just found this clever little app drive droid that lets you boot from iso from your mobile. It would be interesting to know how it works. Does anyone have any knowledge about it. Drive droid

P.S. sorry for my bad english

# Answer
There is a dedicated thread on XDA forum about this application

> DriveDroid allows **you to boot your PC from ISO/IMG files stored on your phone.**

DriveDroid relies on the kernel of Android, in particular the USB Mass Storage (UMS) feature. It allows your phone to act as an USB-drive and have a device (SDcard) or file (ISO/IMG) be used as the content for that emulated drive.

* USB-drive and CD-drive emulation

> These two modes allow your phone to act as an USB-drive or as an CD-drive. Most devices only support USB-drive emulation. Some devices only support CD-drive emulation.
>
> To get both USB-drive as well as CD-drive emulation on your phone you need a patched kernel.
>

title: Does a stock email app auto-update?

# Question
Title: Does a stock email app auto-update?
To clarify, two things:
1. I mean auto-updates to the app itself, not syncing to receive emails.
2. I'm not sure if there's a \*difference, but I'm more interested in knowing about the stock apps/versions of stock apps that don't seem to have any way for you to manually update them yourself. For example, on my Galaxy S7 Edge (running Android 7.0), in the stock Email app, I can go into the Galaxy Apps store, or through the email app settings to the Galaxy Apps store to update the app; but on an Alcatel OneTouch Elevate I have (my previous phone)(running Android 5.1.1), there appears to be no way at all for me to update the stock Email app.

So, my question turns into: Do stock email apps, like the one on my Alcatel, auto-update? Does it perhaps get updated as part of the system update?

\*by this, I kind of meant that I'm not really interested in knowing whether the stock email apps that you can manually update will also auto-update. So perhaps another form of the question is: If *you can't* update it, does it auto-update?

# Answer
There is a global *Auto Update* option in Android 7.0 (possibly previous versions but I can't check now) which automatically updates all apps.

There is also a per-application setting. In case you have the global option off, then you can have that one enabled and it will still auto update. So be sure that *both* are off if you want the app not to auto-update.

By default, I believe the global option is on but that might depend on the phone.

For clarity, when an app is updated, we call that an *update*, when its data is updated, we call that a *sync*, such as downloading new emails as they arrive.

Stock apps are part of the system, so they will update when you accept a system update.

# Question
Title: All links open in Browser, how to stop it?
So I got a rather new (but cheap) Y100 Plus from Dogee with Android 5.1 and ALL Links open to the browser. Even when someone sends me a Location, it opens Google Maps in Browser instead of the App.

I was NEVER prompted with what app to open any link, which is pretty weird, and probably the cause of my problems. That also means that resetting the preferences on my Browser doesnt do anything (tried that). More annoying, "Open Link With" which would have been my workaround doesnt hep, because my browser doesnt give me the share option.

# Answer

If you only have a single app for browsing installed on your phone, then all links will have to be opened in it, if the app from which you are clicking the link doesnt provide in-app webview, to open links.

I had a similar issue with my Nexus 4 after flashing the factory images

What fixed it for me was going into \[stock\] recovery and selecting clear cache and doing a factory wipe, that seemed to fix the partition sizes

Oh also check to see that you have the latest bootloader on the device too, check out https://developers.google.com/android/nexus/images for the most recent factory images

# Answer

From my experience the partitions are on ext4. Maybe there is an option on fastboot (I never used it) where you can specify the patition type. That might solve it.

# Question
Title: Switching superuser permissions?
I used Kingoroot to root my Micromax Canvas A116 yesterday. And Kingoroot installed its own superuser app as a rooting procedure.

The problem is kingoroot's superuser is paid and displays ads and auto install apps if you don't buy it. I tried downloading Supersu but it gives an error "SU binaries occupied". How can I change superuser permissions from Kingoroot to Supersu?

Thanks.

# Answer
Well first of all DONT root with Kingoroot, Kingroot, or with any other one click rooting crap. They install ad binaries that run with root permissions mine IMEIs and things like that.

https://forum.xda-developers.com/showthread.php?t=2516942

> Remember the little discussion we had going in a thread here regarding vRoot, and i joked about vRoot was mining IMEIs? Well, apparently it's true. We have only ourselves to blame. I'm already rooted so i'll unlock my bootloader and install recovery. That way i don't need to root again if i screw something up. You "should" do the same if you're already rooted and don't care about losing Gracenote and X-Reality. Remember to backup your TA folder. What does this mean? What are they able to do with our IMEI's (if they have them)? I'm not sure, and i won't speculate.

https://forum.xda-developers.com/showthread.php?t=2515851&page=3

> ... What XDA is concerned with is the fact that your devices Serial number and IMEI numbers are collected during the root process. This is something which is not necessary at all in order to achieve root. They also use free servers in China in order to minimize cost to themselves. That is the concern. The reason you have seen back and forth on the subject is that it takes time for developers to reverse engineer the process to see exactly what it does. So XDA at this time has taken a position that links to the Kingo or vRoot methods will not be posted on XDA. You are free to use Google and search it out and use any method you want. You aware of the risks just like any other mod you do your device. Kingo has said they are correcting this and will be coming out with an app which will be self sustained and connection to their servers will not be necessary. They say it will be 2.0 Until such happens we will not be allowing the links, but you can discuss it all you want. To be accusing the Kingo developers of doing underhanded things is just wrong and total made up speculation. XDA has to take the communities safety as priority #1. Just look at this way would you take a screen shot of your devices status screen posting all your IMEI and personal information on a public forum on a site of developers and hackers? It's always better to error on the side of safety. EFM Have a great day!

But to answer your question SuperSU can only manage the SU requests if it self has SuperSU, so you need to

1. Replace it with SuperSU VERSION 2.79 (the version is important)
2. re-root with CF-auto-root over ODIN or .zip file

Title: "Uninstall old version" before installing, but can't find it
Spotify doesn't show up anywhere (I used to have it). When I try to install the app, it wants me to uninstall the old version. But the old version doesn't show up anywhere. Tried going through "My Apps" and through the file menu when hooked up to a PC, and I cannot find it.

Any thoughts?

# Answer

Spotify may be installed as a bloat-system-app so try Apps\>right upper corner the three dots\>show system apps. It could be that you hided the spotify app.

Additionaly you can type in the terminal `pm list packages` and use grep to filter so like that `pm list packages | grep -i spotify`. you can uninstall it by typing `pm uninstall [package name]`

Note the above assumes you're either using or running the commands as root. `pm uninstall` on system apps can only be performed as root (if at all) – for the other mentioned `pm` calls, connecting via ADB is sufficient.

I have tried researching the application and I've come up with nothing. When I click on the app, it tells me to insert my device into my Gear VR.

If the update is saved to the cache partition as Bo indicates, you could reboot into Recovery mode and wipe the cache partition from there. You can look up the key combo to get into Recovery, or if you have USB Debugging enabled and `adb` installed on your PC, you can connect the device and run `adb reboot recovery`.

This works only on marshmallow and newer versions. Most of OEM's doesn't offer in gui option for adoptable storage. So you have to do it via ADB. Here is how click

Here it is: NOTE all data on your SD card will be lost.

1. Make sure USB debugging is enabled in developer options under settings and then connect your phone to PC via USB cable.
2. Open terminal or command line on PC ( make sure you have ADB installed if not then download minimal ADB and fastboot, you can find it on Google click ) type command "**adb devices**" to make sure phone is detected, then type "**adb shell**" 3.Type '**sm list-disks**' to list the disks available, the result should be something like "*disk:179:160*"
3. To make SD adoptable use command "**sm partition disk:xxx:xxx private**" where *xxx:xxx* is replaced with result from previous command, in some cases there is **_** instead of **:** so watch out for that. If you want to use only half of SD as adoptable then use this command "**sm partition disk:xxx:xxx mixed 50**" and that's it.

If you want to move your data (pictures, videos etc) you can go to settings\>storage\>SD card\>more and you will have there option "migrate data" hit it and let it go.

It doesn't show on recent apps list and once I tell it to perform the fix, i can't interact with app or go back to it.

# Answer
Install Shutapp from play store and close all opened applications through it, you'll see all the opened apps and doing this may fix your problem.
Find the conflicting one. If it's not a system application, you'll see it in the list.
Also, You can click just below the big circle to see the list without closing the apps. Check whether that list has any unknown app.

# Question
Title: How to override the time zone for some particular country?
How can I get my Android device to show a different time zone for a particular country?

So, when I pick the country I’d see the overridden time zone instead of the default one.

I have a rooted device with system version 4.4.2

**Edit**

Say I want to pick London, Dublin with automatic time zone disabled, but rather that showing GMT+0:00, I want my device to show something else, say GTM+0:30, is that possible with a rooted device?

Also I want that "fake" time zone to be reflected in the clock as if it were the actual time zone. So when it's 12:00 in London I want my device to show 12:30 instead.

# Answer
First of all: There is no official way to change time zones because they are provided from the server so you would need to add the time zones there.

Second: if you go into settings -\> date and time you can change the time there and subtract/add the amount of time you wanted the time zone to display.

With something like UCCW and a status bar customizer you could customize widgets. You could, of course, create a clock with an offset and display a text next to it saying: GMT +0:30 but this would not be in the entire android UI.

If you have a status bar customizer like Omega Status Bar you can customize your own status bar and set/remove text so you could set the time in android to be 30 minutes less and display 5 "GMT -0:30" next to the clock on your status bar.

If you have any questions feel free to ask.

Some computers only recognize devices when they are plugged into the right usb ports. Have you tried using a different port? Also, some chords can be finicky, some of the cheaper ones don't like you when you try to do get into a device like that. Another thing you can try is to do like someone commented, and make sure you have the right driver for your device for your computer to recognize it. Just google search for the right driver for your model.

```
http://myserver.com/daily_reports/Day_20170701.htm

eventually

```
http://myserver.com/weekly_reports/Week_2017_27.htm

With Tasker this is very easy.

Setup a task like this:

1. Code → Run Shell:
    * Command: `date +"%Y%m%d"`
    * Store Output In: `%date`
2. App → Launch App → select your browser app:

For weekly URL, create an another task:

1. Code → Run Shell:
    * Command: `date +"%Y_%V"`
    * Store Output In: `%week_no`
2. App → Launch App → select your browser app:

You can save these two tasks, create a shortcut to them on your home screen and tap that shortcut to open the concerned URL. Or, you can setup a profile in Tasker for your requisite automation and attach those tasks to that.

My big brother has the same phone (ASUS Zenfone Max). He installed an app where he can send built in apps to other devices via APK. So he sent the Download Manager APK on my phone, tried to install it but the "com.android.providers.downloads is not working" still keept popping out. In the end I decided to Factory Reset my phone. And it worked.

My phone is not rooted so I was shocked that I deleted a built in app. Maybe because of the pop up download I got when I went to a website (I was checking sites to download Korean Dramas). I read from forums that if they deleted a built in app and chose factory reset there was no assurance that the said app will be in the device, so I presumed that by sending and installing the original apk file of DM and by choosing Factory Reset the system will recognize the installed apk file and reset it.

You can download a firewall app and restrict YouTube to WiFi only.

It appears my comment was incorrect, once you Enable OEM Unlocking in developer options, you have disabled Factory Reset Protection completely.

> If you have Developer options turned on, you can also turn off device protection from your device's Settings app. Tap Developer options and then OEM Unlocking. \- Source

And no, once you have unlocked the bootloader (required to root) you can not re-enable this switch, it is greyed out and non-functional, unless you relock the bootloader which cannot be done without have a completely stock image installed, meaning no root, custom recovery, or other modifications to the device.

As I have answered here, it's the UID of a **removed** app. You can safely ignore it as it will disappear sooner or later.

Title: How to switch from front to back camera on naxa 9" Core tablet
When taking a picture oh a Naxa 9" Core tablet, it will only display the front camera, not the back camera. I have touched the Camera Icon on the screen but it just takes a picture instead of switching the camera to the back camera like the instructions in the manual says. Is there a quick fix for this or do I need to return the item to the store.

Title: I have an Archos 55 Platinum. How do I turn off vibrate when I'm typing?
I've turned 'vibrate' off in a couple of places, but it still vibrates when I'm typing an sms message. It's really frustrating.

By default, pressing the touchscreen creates a vibration. This functionality is available in two parts: general interface and virtual keyboard. To completely remove vibrations of this type the option must be deactivated in both sections in the Settings app.

From **Settings** \> **Sound** , **uncheck Vibrate on touch.**

From **Settings** \> **Language & Input**, in the section **Keyboard & input methods**, press the **settings button** next to Google Keyboard (or the 3rd party keyboard that you are using) and **uncheck Vibrate on keypress.**

Title: Android 4.1 Locked Out
I am messing with an old Android my Little Sister had before she switched to the “darkside” (iPhone).

It has a 4 pin lockscreen (Not 3rd party) and my sister forgot the pin. I removed it from device manager years ago cause she didn’t use it, so I can’t remote whipe or anything.

Being a casual user, my sister never enabled USB Debugging, so I can’t connect to a PC and access it that way.

The WiFi is off and her service was discontinued 2 years ago so I can’t do anything that way.

Tracfone also disabled recovery mode, so holding Power+Vol+ sends it into a bootloop until I let go and it boots to Android. I tried every possible combo and even letting go and clicking them again to no luck.

It’s an LG Optimus Fuel running non-rooted Android 4.4 with the LG Optimus UI Launcher.

I assume it’s a brick, but is there any thing I can try?

You can still flash the phone by installing a new ROM, this will factory reset the device. But I think you are doing wrong while trying to manually hard reset the phone. Follow the steps below:

**Works for Tracfone LG L34C Optimus Fuel model:**

It’s a little bit complicated, just follow this guide:

* Power OFF the phone.
* Press and hold Power button and Volume Down button in the same time for several seconds.
* Keep doing this until you see LG logo appears on the screen. When the logo is appear, release both buttons **but for 1 seconds only.**
* **Remember to release both buttons just for 1 seconds before you press and hold them once again.**
* If you do it right, the device will boot into Recovery Mode. Now you can release both buttons.
* In recovery mode, navigate through the menu using both Volume buttons and Power button to select.
* Select YES on the first dialog box and another dialog box will also show up to confirm your action. In the second dialog box, select “Yes” and let the factory reset process begin.
* Done.

Title: Installing TWRP on a locked OnePlus One without wiping data
I am trying to upgrade my OPO's operating system from CyanogenMod to the latest nightly version of LineagOS.

As a first step, I tried installing TWRP, by executing from my shell the command:

```
fastboot flash recovery recovery.img

```

But I got the following message:

```
FAILED (remote:         Device not unlocked cannot flash or erase)

```

I read in a few places that I should first unlock my device by executing the command `fastboot oem unlock`, but that it is going to erase all my data.

Is it true? Is there a way to avoid the erasure of the data?

# Answer
NO. Period.

If you want to unlock the bootloader erasure is inevitable. You can make a backup, but I'm not sure it'll be restored. However what is the point when you flash a custom ROM you'll need to wipe data in that case anyway. However you can move media to SD card pull it out and unlock bootloader (Make sure the SD card isn't encrypted).

The phrase 'Device Protection Manager' is an uncommon name for this software. Usually it is truncated to 'device protection'. I found a link that may help you.

https://www.greenbot.com/article/2904397/everything-you-need-to-know-about-device-protection-in-android-51.html

Basically, it is anti-theft software, plus... You could have 3rd party software that is doing the same thing, so you may want to scour your device for such and eliminate all but one. Choose one that doesn't drain your battery so much.
