Title: How to downgrade from Android 5 to 4.4.4 on an encrypted phone?
After certain troubles with Android 5 (see How to fix file permissions on Android 5 so that a certain app can access certain files?) I decided to go back to 4.4.4 on my Nexus 4 for the time being. Thereto, I restored a backup I made prior to upgrading using the TWRP 2.8.2 restore function. The restore in itself went well, and after reboot the familiar 4.4.4 boot animation came up.

But when I entered my encryption password, I immediately (no discernible delay) got a "Try Again" message. I retried several times, but my password wasn't accepted. It was definitely the correct password I entered, for in TWRP, it works.

I now restored Android 5 from a backup I made immediately before restoring Android 4.4.4, and my password is accepted again, but of course the Android 5 problems are back as well.

So: how do I properly downgrade to 4.4.4 on my encrypted Nexus 4? Thanks.

1. In L, take a backup of things you want to save (photos, videos, app data, etc)
2. Go download a stock rom for your device, such as this one
3. In TWRP, wipe data, system, cache and dalvik cache
4. On your computer use fastboot to flash the system.img
5. Reboot
6. You should now boot into kitkat, without any encryption.
7. Restore any backups you might've had. Note that if you simply backed up the /data partition, that might cause problems when restored.

7b. If you did create a backup with twrp, you can still restore in a safe way
with titanium backup pro, assuming you root the device.

Title: Hands-free/Driving Mode: How to change the reading voice's language (and voice: male/female etc...)?
Is there a way to change the language and voice for reading out the information on hands-free mode. Even better, it would be nice if the language and voice for the alarm could be set on a per-alarm feature. Anyone knowing if and how this can be done, please don't hesitate to reply.

Thanks.

# Answer
Go to **settings** \> **language and input** \> **text to speech output**.

There you can select one of your installed voices. You can install voices from the Play Store. My personal best and free is IVONA (https://play.google.com/store/apps/details?id=com.ivona.tts&hl=de)

I would go to the forum section of your device with whatever site you use and find the links for Odin and Samsung's official Kit Kat release for your device and flash that using Odin. Then you will be stock once again then accept the update and all should be fine.

Title: folders of apps not downloaded created in my memory card
I use Sony Xperia Z phone Recently i noticed that in my phone some empty folders of applications like hike and hookup are created. I did not download these applications...so how these folders came in my memory card. I had recently mounted my memory card in my friends phone which had these apps.. is it possible that these folders got copied from his phone to my memory card ? please help.

Yes exactly. Applications create (not copy) required folders as soon as a memory card is mounted. There is nothing to worry about and you can delete them manually. As an extra note - these folders are created for saving media files received and backup files.

# Question
Title: Call recording problem
I use a Samsungs Galaxy Star Pro GT-S7262 with Jelly Bean 4.1.2. I have installed quite a few call recorder apps from Google Play and though they are recording all the calls, whenever I play back the recordings it sounds like everything has been recorded in fast forward mode (or is playing as such). It is happening with all the call recorder apps I have installed. What could be the problem and how can I resolve it as everything sounds jumbled and indecipherable

# Answer
> 0 votes
Some phones just can't support call recording because of how the hardware is designed. If you've tried several apps, and none of them work correctly, that is probably the case here.

# Answer
> 3 votes
I have the same problem and also installed many callrecoders, but all gave the same problem. I downloaded the audio files from my phone and loaded them into a sound editor (i.e. sony soundforge). I played the file 5.5 times slower and noticed that they played well, I could understand the conversation perfectly. So it seems that all is recorded only played back 5.5 times too fast. This is a problem which can not be corrected within the phone. My advice: download all audio files to a computer, convert and save them with the new speed. They will work fine!

# Answer
> 0 votes
I discovered that on my Samsumg GT-S5282, call recording apps will always record my files exactly 83.097% faster than the files should be.

As a workaround, I use Audacity on my PC to normalize the audio after recording. I change the Audio Speed by -83.097% and then change the Pitch by -4%, then export it as a .wav file. This fixes the audio so that it will sound normal when played back.

# Question
Title: How to share android screen with users outside LAN?
I work as a developer from home and I wish to demo the android app to my boss. He doesn't have an Android phone, so I have to demo the app from my phone and demo all scenarios for him from my android phone.

The question is how do I share the screen with him ?

Here's what I tried ?

1 - BBQdroid exactly what I want but it only works in a LAN, in fact I have to specify the android local IP address i.e. 192.168.x.x

2 - Teamviewer quicksupport but it exposes all the apps on my phone and it's not live sharing, I have to keep on sending screenshots.

3 - AirDroid only screenshots, no live sharing of the android screen

Please help me guys find a way to share the android screen live with my boss.

Thanks

# Answer
You can use BBQDroid, but it will require additional tweaking on your router.

First, you'll have to find out your IP. This can easily be done by typing "my ip" into Google, which will return your public IP.

Next, you'll need to go into your router settings and add your Android device to the router's DMZ, meaning that all incoming connections get forwarded to your device. Find out the model name and brand of your router, then look up instructions on how to access the DMZ.

By this point, your public IP should direct to your phone. Launch BBQDroid on your device and attempt to connect to it using your public IP from another device.

When you're finished, I'd recommend removing your Android device from your router's DMZ, as a security precaution.

# Question
Title: Fooling a tablet into thinking it's a phone so that Amazon Prime streaming will work
This relates to question:

Using Amazon Instant Video from Amazon Prime on Non-Kindle device

However things have moved on since then. Amazon have now released a version of their Amazon app for use on non-Fire Android phones, and indeed streaming of Amazon Prime is now possible. However the Tablet Amazon app does not have this functionality, even though it is running the same Android OS version (as the scores of negative reviews on the app will testify!) There doesn't seem to be a way to install the Mobile Android app onto a Tablet. It appears that they only allow Amazon Prime to be used from their own Kindle Fire Tablet.

Is there any way I can fool my tablet (Nexus 7) into thinking it is a phone so that I can install the Phone version of the Amazon app and therefore enable Amazon prime streaming?

# Answer

You can install the .apk http://www.apkmirror.com/wp-content/themes/APKMirror/download.php?id=2395 *Note: Make sure you enable installing from* ***Unknown Sources*** *from* ***Settings\>Security***.

If you cannot install the apk, you will have to root your tablet. You can probably find a guide at forum.xda-developers.com

1. After rooting your device, install *Xposed installer* http://dl-xda.xposed.info/modules/de.robv.android.xposed.installer\_v33\_36570c.apk *Note: Make sure you enable installing from* ***Unknown Sources*** *from* ***Settings\>Security***.
2. Install *Play Store Fixes* from **Xposed Installer**, from the **Download** screen *(There should be a drop-down selection menu in the action bar)*.
3. Go into the **Modules** screen *(using the same drop-down menu in the action bar)* and enable **Play Store Fixes** via the checkbox.
4. After enabling, open the **Play Store Fixes** app by selecting it from the **Modules** screen in **Xposed Installer** *(or from your app drawer)*.
5. After you open **Play Store Fixes**, set the DPI (density) to **320** (phone dpi).
6. Go back into **Xposed Installer**, either by pressing the *Back* button or opening from your app drawer.
7. Go into the **Framework** screen. **Install** the Xposed framework.
8. After the installation has installed successfully, **Soft Reboot** your tablet.
9. Open **Play Store** and search for *Amazon*.
10. You should now have the option to install Amazon. *Note: If not, try setting the density to* ***240***.

Hope this helps!

I've come across this quite a few times. I know it is possible to do this by modifying the build.prop file to fool an app into thinking your device is something that it's not, but that requires rooting, and you also run the risk of soft-bricking your device (happened to me yesterday).

If you are willing to take such a risk, create a nandroid backup before modifying build.prop

# Question
Title: How to root Samsung Galaxy Ace II X
I have a Samsung Galaxy Ace II X smartphone, and for various reasons, would like to root it. It is running android version 4.0.4. How exactly do I root it? Should I download the necessary files, or make them myself? (I have no idea how to make them). I would also like to somehow have a way to undo the rooting if necessary, and have a backup of everything on my phone now. I have heard that rooting could cause my phone to become a "brick" or be completely useless, should I be concerned about this?

Also, my computer is a mac, if that makes any difference whatsoever in the rooting process.

# Answer
There are several root options for Samsung devices.

**EDIT: It seems like the first method is not available for your device.**

* CF-Auto-Root: Created by XDA developer Chainfire, this method consists of a modified recovery image which injects the `su` binary into the system and restores original recovery upon reboot. This is the safest method because it does not require user interaction.
* Root programs: These PC apps, like OneClickRoot, require you to enable USB debugging and connect your phone to your PC. It will then execute an exploit which will allow it to inject `su` to `/system`.
* Framaroot: Created by XDA member alephzain, this is the only root method that does not require a PC. Once installed and opened, Framaroot will present you with a list of exploits compatible with your phone. Once you choose an exploit, Framaroot will either a) tell you that the exploit was successful and that you need to reboot in order to enjoy root, b) tell you that the exploit failed and that you should try another, or c) it used a so-called `local.prop` trick to root your device with a squashed file system, and that you should reboot to try and see if you have root.

All methods install a Superuser apps which governs the use of `su.` An example of a su app is SuperSu, which has an unroot option in its settings tab.

As for the bricking, it's very hard to do that unless

* You interrupted a flash process
* You deleted something you shouldn't have
* You flashed something meant for another device
> 1 votes

# Answer
Check out the XDA FAQ thread for the Galaxy Ace II X.

After you thoroughly research rooting and its pros/cons, if you decide to root, the instructions are in that thread. Since you are on a Mac, you will not be able to use *Odin*, which is designed for Windows. You will have to use the Mac/Linux alternative, *JOdin*, as explained in this video. Good luck!

*Note: About* ***bricking*** *your device: I wouldn't worry about it, in all my years of rooting and tweaking, I have not had one brick. The only way to brick is to modify something you know you really shouldn't, unplug something while your bootloader is connected to your computer, or using a corrupted download for rooting/bootloader operations. Just use this general rule of thumb: Look on the XDA thread. If someone has done it and their phone is not dead, then it is typically safe to do.*

Title: Would an android device pass the boot screen/enter recovery without build.prop?
Is it possible to start up an android device without build.prop? Is it even possible to use stock recovery without build.prop?

# Answer
Yes, you can boot into recovery without build.prop. You can, in fact, boot into recovery without anything in /system (actually, recovery and bootloader are the only things you can boot into without anything in your /system.); build.prop and /system are only used when the ROM is loaded.

Title: How much RAM does a Huawei H868c Glory have?
I want to run "Terraria" on my Huawei H868c Glory, which is running Android 4.0.4.

How much RAM does it have?

# Answer
The amount of RAM for the Huawei Glory (H868C) is **512MB** (390MB available to apps). According to Terraria via the Play Store:

> Optimized for Android OS 3+ and requires 512MB RAM.

So, you *should* be able to run it. If you are able to install it from the Play Store, then you will most likely be able to run it. It doesn't hurt to try.

# Question
Title: boot process recovery or rom
When I power my device (htc one m8) on and press the volume down key I get into recovery.

Now which part of the booting process checks if this key is pressed and uses the correct partiton (boot or recovery).

Is this the bootloader?

If yes, is this the 'same' bootloader as formerly found in the aosp tree?

# Answer
The initial input is read by the *bootloader* to see which partition to boot. *Vol-* will trigger *bootloader*, while no input will trigger *ROM* partition. The bootloader is initially installed by your OEM. No matter what version of Android you have, you still have the same bootloader until you either update your bootloader or install a custom bootloader. The OEM bootloaders are *likely* based off the AOSP tree, depending on your specific phone (I am not sure for the M8).

# Question
Title: How to login only to Google Music and not the other Google services?
I have Google Music All Access and I have an old unused Huawei Honor floating around. I want to set it up as a Google Music playing device for the kitchen.

I am wondering now: How do I login only for Google Music?

I want to allow guests access to the device in a sort of kiosk mode, but I would not like them having access to my mails and other private data.

# Answer
As someone who tried to keep a select few Google apps from opening a bevy of other Google apps, just to preserve battery life, and that failed so spectacularly that I opted to use non-Google apps, I have a suspicion you really can't do it **unless GMusic runs in kiosk mode** (possible; I use iPods for kiosk music so I'm not sure about GMusic).

If GMusic doesn't have a kiosk mode, maybe you can **run GMusic in a kiosk *browser*** like SureFox? (*I think you can, but it's been a while since I've tried GMusic*). There are several of those to try.

But I imagine your best bet is seeing if one of the paid kiosk apps works well with your phone. Note that some of those apps reportedly "mess up" certain phones/tablets, so check the reviews on Playstore for your particular device before trying/buying one.

Title: Install a new OS after wiping out the OS on Samsung Galaxy Exhibit 4G
I have wiped the OS off of my Samsung Galaxy Exhibit 4G (T679). Now all I get is the flash screen.

How can I install a new OS at this point?

# Answer
> 0 votes
All credit goes to stubbakatt over HERE for the files and original instructions. I simply walked through it myself and re-wrote out the instructions in a way that caters to my brain.

**Disclaimer:** This has been tested on two machines - one running Windows 7 32 bit, and one running Windows 7 64 bit. This has not been tested on an XP machine (though it should work the same) or on a Mac. And of course, I'm not responsible if you brick your device, proceed with caution, etc. etc.

***FILES NEEDED:***

* **Drivers: click here** (Google Docs automatically pulls up the content of the .zip - simply go to the top left and choose File then Download to download the .zip) - if you're rooted/rommed, you probably already have these, but just in case these are the drivers I used
* **"Back to Stock" - Odin, ops, factory image, etc: click here** (Google Docs automatically pulls up the content of the .zip - simply go to the top left and choose File then Download to download the .zip) - this is the main stuff that Odin will use to flash your phone back to it's factory state

***STEPS:***

1. Make sure the computer recognizes your phone with the drivers above (again, this is probably already the case if you're having to do this!)
2. Unzip the "back to stock" .zip file to wherever you want - preferably somewhere easy to get to (desktop?).
3. Power down your phone. Once it's off, hold down the volume-down button and press power. Hold both down until you see the "Warning!!" message with the yellow triangle at the bottom. Once you see that, hit the volume-up button. This puts you into Odin/download mode.
4. Plug your phone into your computer.
5. Among the files you unzipped from the "back to stock" .zip file, open "Odin Multi Downloader v4.43.exe". Once it opens, the Message window at the bottom left should read "Added!!!" and "Detected!!!".
6. Make sure all four of the Options are checked (One Package, Auto Reboot, Protect OPS, Reset Time \[mine's set to 300 seconds\]). I don't know if this is all necessary, but at the very least One Package and Auto Reboot appear to be.
7. On the right side, click the "OPS" button, and select/open the Ancora.ops file.
8. At the bottom, click the "One Package" button, and select/open the "T679UVKJ1\_T679TMBKJ1\_T679UVKJ1\_HOME.tar.md5" file.
9. The Message window should do an md5 check and end with "Check MD5... ok". If it doesn't, try redownloading again - don't want to flash a corrupt file!
10. If all of that is good to go, then select the "Start" button.
11. Your mileage will vary, but for me it took about 5 minutes, then the phone reboots itself into recovery mode (the little white box with the progress bar), then about 30 seconds after that and the phone fully reboots. Don't unplug it yet. After a few minutes (actually, the 300 seconds set in the "reset time" in Odin), it will say Pass!!! and you're good to go and unplug the phone.
12. However, we're not quite done yet. Our goal is to get back to a factory state. You'll notice a lot of your stuff is still in place - apps, etc. That's because this process doesn't touch the /data partition of the phone. In addition, it's possible you COULD still be seeing the Superuser app. If that's the case, simply go into your application settings (settings \> applications \> manage applications), find Superuser, uninstall it. It will say uninstall not successful, but it should disappear.
13. The last thing to do is simply a factory reset - this will wipe out the /data partition, back to stock, and you'll be done. This could also take care of Superuser, but I've never tested it to see since it's easy enough to do it before the factory reset.

So there you go - hopefully you're now sitting on an "out of the box" Exhibit II 4G to do with whatever you please.

# Question
Title: Can update.zip update-script be used to copy build.prop to an SD card?
I made the unfortunate mistake of lowering the dalvik heapsize to 64m and now my tablet is stuck in a bootloop . I've tried to make my own update.zip (including signed ones) and all fail to load in recovery mode, saying "Installation Aborted".

Is there any way to use update.zip to pull build.prop from the device? My computer does not find it on ADB so this is my only option.

\**Edit: I've now got a copy of the original build.prop from the stock ROM. I'm now having trouble getting that back on to the device, as it keeps halting at the extract section. I'm wondering if there is something wrong with the permissions I'm using or do I need to specify in the updater-script to delete build.prop?

```
mount("ext4", "EMMC", "/dev/block/mmcblk0p6", "/system");
package_extract_dir("system", "/system");
set_perm(0, 0, 0644, "/system/build.prop");
show_progress(0.100000, 0);
unmount("/system");

```

Since my recovery doesn't show output for **ui\_print();** I've used **show\_progress();** to see how much of the code gets run. It successfully mounts and runs anything, except extracting the package, where it just hangs up and says "Installation Aborted".

# Answer
> 0 votes
I fixed the problem by backing up using the stock recovery, then reflashing the factory firmware. I then went back into stock recovery and restored my user data.

The reason why it wouldn't accept my update.zip files is because they weren't signed by Archos.

# Question
Title: How to delete a Play store accpunt through system
I have sold my old android mobile to a person and made sure that the mobile was completely formatted.

But, when I try to view the list of devices in Play Store it is listing both my new and old mobile phones.

Is it possible to remove this old phone from the list so that the other person doesn't use my account?

# Answer
If you performed a /data wipe (**factory reset**) on your old phone, **you have nothing to worry about**; that person will not be able to "automatically" log onto your Google Account. Old phones will *always* show up on Play Store when you're looking from your PC.

You cannot remove the device from Play Store, but you can hide it from your **Google Play Settings** from a PC. Just untick *Show in menus* next to the device you want to hide.

# Question
Title: Nexus 5 IMEI number gone after updating to Lollipop
My IMEI number has disappeared on my Nexus 5 and now I can neither call nor text.

Status of the phone says:

* Network: Unknown
* Mobile network type Unknown
* Service State: Out of service
* Mobile network state: Disconnected
* My phone number: Unknown
* IMEI: Unknown
* IMEI SV: Unknown

All of this happened after updating to Lollipop using bootloader.

I have tried several tutorial videos, such as:

* "How to Unroot Nexus 5 on Mac! - Restore to Complete Stock",
* "How to Upgrade, Downgrade, Restore ANY NEXUS Device on a Mac - Easiest Method"

Now is my Nexus downgraded to Android 4.4 and I can't text or call anyone. When I try to open the Camera I get the message "Unfortunately camera has stopped". The same thing happens with Google Play Store.

When I try to take a screenshot I get the message "Couldn't save screenshot. Storage may be in use." It's like it can't connect to the storage.

**Can I fix this? Is it possible to restore the IMEI without any backup?**

If not, should I lock the bootloader and send it to my carrier (I live in Sweden)?

**Note**: I have the IMEI number written down.

# Answer
There is nothing to worry. Please follow the steps mentioned in this Android Enthusiasts answer.

You just have to flash the images properly. Do a factory reset using the recovery mode.

* Volume Down + Power
* Bootloader screen will be visible
* Go to Recovery
* Power + Volume up key (few seconds) and then let go of the Volume up key, but keep pressing Power
* Select Wipe Dalvik cache
* Select Factory reset

It seems there is a known bug for devices running on Android 2.x. (Samsung Galaxy S1 and its siblings run on Android 2.x.)

From Retrica's FAQ #14,

> # I am using an Android device. Why can't I see the preview?
>
> It often occurs if you are using devices that run Android OS 2.x version. Retrica team is aware of the issue and working on a fix. In the meantime, inquire your device manfacturer for any assistance to upgrade your Android OS to the latest version.

Probably, the only way is to unofficially update the Android OS version (to at least Android 4.0 ICS) by flashing custom ROM.

When I moved an app to the Storage Card on my HTC One V, I found some data moved to USB Storage App. The Storage Card is still showing not used. What's "USB storage app"? Why apps are not moving into the Storage Card, instead moving into the "USB storage app"?

1. Before moving the app to the storage card

2. After moving the app to the storage card

# Answer
I guess you have to read the "USB Storage App" as the USB storage used by the app itself. So the code of the application.

If your application would for instance start generating cache information, saved pictures etcetera. And if it would save that information on your Storage Card, then the information will be showed under Storage Card.

So under "App" and "Storage Card App" is only the information and code of the application itself, not the information or data it generates. So in most case these 2 numbers will not change over time. And then under "Data" and "Storage Card" information generated by the application can be found. Either on the Storage Card or the internal memory (depending on the application I guess). This is the information managed by the application (local databases etc), so this will probably change over time, depending on the application in question of course.

This is my interpretation of those 4 terms. And if I check for some applications I use, it looks like my interpretation is correct. It is certainly correct for the applications I created myself, so for these apps I know where what information is saved on the phone.

# Answer
"USB storage" is the "internal" SD card i.e. the partition on the phone's internal memory that is treated like an SD card for general data storage.

"Storage card" is your actual physical microSD card.

The latter is where the stuff moved via "move to SD" or "move to storage card" gets put.

As for why it does this, Android's system for storing app stuff in user storage hasn't caught up with the concept of having more than one section of user storage.

# Answer
The answer posted by @ndsmyter seems almost correct. The applications under `Application manager -> SD CARD` are those applications which can, at least in part, be moved to the SD card (and this happens where the checkbox next to the application's entry is checked). At first sight it may seem like "Application" and "SD card app" are for code on internal storage and on external storage, respectively, whereas "Data" and "SD card data" are for application data generated by the application on internal storage, and external storage, respectively.

However, upon further inspection I realized that on my Samsung Galaxy SIII I don't have an external SD card inserted, and despite this, while none of the applications listed under `Application manager -> SD CARD` have the `SD card app` field displaying anything but `0.00B`, the example below, and many others, shows that `SD card data` is nonzero even though I don't have an SD card (click the image to enlarge):

So, the only thing I am able to conclude is that these values are not the number of bytes taken up by the application and its data on internal and external storage, but rather how the data would be distributed among these four locations should the user decide to transfer the application to the external SD card (and some portions would still need to reside on internal storage for technical reasons).

Also note that on my device the field names are different. What on the original poster's post is called USB storage app on my system is called SD card app, very confusing.

And just as confusing is the fact that when I change the UI language to Italian, what in English was called "SD card app" now becomes "SD card applications" (applications: plural), which means not even the people that localized the system could figure out what these fields represented.

Regards.

Title: Why does Wiko Cink Peax 2 reboot when it receives an SMS containing only '=' (equal sign)?
I have a Wiko Cink Peax 2 and when I receive one SMS with the only character '=' (equal sign), my phone reboots the system. How can I fix it?

# Answer
It seems this is a known bug that affects majority of Wiko phones. Receiving an SMS with '=' (equal sign) as the only content will soft reset the OS.

References (in French):

There is a suggestion from the first site: Use other messaging app, disable the pre-installed messaging app.

Flashing custom ROM **doesn't** seem to fix the issue. It might be caused by hardware issue, but currently there is no update on the real cause.

If it's still in warranty, then maybe it's possible to ask for replacement and ask them to test this issue first.

# Question
Title: Interruptions are either broken or some apps disregard settings?
So, I updated to Android 5 and I discovered this new feature, interruptions and priority notifications.

I set up the phone to interrupt me only for calls and messages and I went to sleep.

I was woken up by Facebook Messenger notification sound. Pissed off, I decided to check again if it was by chance whitelisted.

Is this behavior normal? Are Whatsapp, Telegram, and those kind of instant messaging app supposed to bypass this setting?

# Answer
> 4 votes
The problem stems from the fact that Android has multiple audio channels, for different kinds of output. The Priority Notifications feature will silence any apps that try to output over the "notification" channel unless they are whitelisted, preventing their notification sounds from being played.

However, not all apps actually use the proper channels. In the case of WhatsApp (and apparently Facebook and Viber), it appears that they may be using the "media" channel, which is intended for music, games, etc. These sounds do not get muted when you set your device to Priority mode because the system does not perceive them as "notifications".

The alternative (silencing all channels in Priority mode) would mean that you could not use any apps that output audio when your phone was silenced. This would effectively be like the (now nonexistent) "silent" mode. Google probably felt that was an unacceptable implementation for what they were trying to do with Priority mode, and has marked a bug related to this as working as intended. The advice given on the bug tracker was to contact the developer(s) of the offending app, because they are not actually using Android's notification API correctly.

In the meantime, you might be able to create a profile with something like Tasker that would help. Something that turned down the media volume to zero overnight might suffice, though I have not actually tested this myself yet. You could also try triggering the profile off of the notification itself, to see if you could just swallow it completely.

Title: What does purple colour mean in GPU rendering profiling?
In this video you can see lags in the Easter egg in Android Lollipop on Nexus 5

What does purple colour mean?

# Answer
> 3 votes
Purple is "prepare"

It has been added in Lollipop, so now we get: draw (blue), prepare (purple), process (red), execute (yellow)

If you do `adb shell dumpsys gfxinfo`, the table for each app now has 4 columns (with prepare added between draw and process)

I have yet to find any documentation on this yet :)

# Question
Title: What is the difference between a proximity sensor and a light sensor?
I've run across the specifications for this Android device, the HTC One V. On the PhoneArena site, the specs have it that the phone has both a proximity sensor and a light sensor. I thought a proximity sensor uses light to detect proximity. What is the difference between these two?

# Answer
> 1 votes
I just checked the Samsung Galaxy SIII Manual which can be downloaded form this site. According to the manual, at least on this mobile phone, the proximity and light sensor are the same physical device. This device is used as a light sensor to increase the screen brightness at night and decrease it during the day, and as a proximity sensor to make sure the screen turns blank when the phone is placed next to the earpiece when receiving a phone call to ensure non of the buttons get accidentally pressed against the user's face.

Despite the two sensors use the same hardware device, two separate software algorithms are used to make it behave as two separate sensors.

Other manuals such as the one for the Samsung Galaxy S Plus which can be downloaded here list the light sensor and the proximity sensor separately, although the appearance of these is always the two small adjacent circles that let light into the hardware behind those two light entrances.

# Answer
> 4 votes
If the proximity sensor worked by simply measuring received light, it would be useless at night :) There are various methods this sensor can work, but the main idea is to decide if the phone is being held up at a person's ear. This is a yes or no question so the sensor doesn't have to be able to measure the distance, there just has to be a designated treshold, which, when crossed, triggers the output value from 0 to 1 (and thus, it turns off the screen).

The light sensor, however, needs to measure the brightness the phone is exposed to, usually to be able to adjust the screen's brightness. This way, for example, it can turn up the brightness in sunlight and reduce it at night.

# Answer
> 2 votes
Feel free to correct me if I'm wrong, but as I understand it, the proximity sensor is what's used in call to stop your face from providing unwanted touch input. It usually glows red while activated and emits infrared.

The light sensor is what is used to measure light levels for things like adaptive brightness.

Title: Galaxy S3 won't boot, gets stuck at the "Samsung Galaxy S3 GT" screen
I seem to have the same problem as many other Galaxy users with the **Boot Loop**. I cannot access my phone:

* I am not able to load the Stock ROM or factory reset it, nor erase any data.
* It is stuck at the ***Samsung Galaxy S3 GT*** screen and then **turns off**.
* If I go to "download" or "volume up mode" (I am sorry I don't know the name) it turns off.

I have already tried:

* pulling the battery out
* waiting until the battery has no juice
* connecting to PC to try to update the firmware

Does anybody know what should be done?

# Answer
It might be a power button issue. when you take the battery out, and put it back in does the phone automatically turn on by itself? or do you have to press the power button to do that? You should turn it back on with the power button, if it turns back on automatically then it means your power button has gotten stuck. What I did was hold it and kept pressing it a few times in order for it to get unstuck. it'll turn on like normal once it's unstuck

# Question
Title: Why do some Android phones have two microphones instead of one?
Some phones such as the Samsung Galaxy SIII have two microphones, one next to the user's mouth which as is the case with most mobile phones, but also a second microphone next to the user's ear. Other models such as the Samsung Galaxy S Plus only have one microphone.

What are the advantages of having two microphones on a mobile phone device?

Thanks.

# Answer
> 5 votes
The second microphone is used for noise cancelling. The phone uses it to listen to the external environment (not including your voice), so that it can filter that out from the sounds it hears using the main microphone. That way, it can reduce the amount of noise that comes with your voice, and make your call more audible to the other party.

# Answer
> 4 votes
As well as noise cancelling, some phones also use the two mics to record sound files and videos in stereo.

Title: N4 lost data connection after Lollipop update - sign into network HOME
I've been unable to use the data plan on my Nexus 4 on a Straight Talk plan after updating to Lollipop.

Data's not working, and I keep getting a notification that says "Sign into network HOME". When I tap on that notification it takes me to a blank screen saying "Sign-in to network". The only options I have is in the drop down menu in the top right:

* Do not use this network
* Use this network as is

When I choose the latter, my data turns on for a second and then stops working again almost immediately.

Any suggestions?

# Answer
I suspect the issue was caused by having Lollipop reset the default access point of the phone provider to Tmobile rather than Straight talk. Setting it to Straight Talk seems to have made it work again. Will report back if anything changes.

# Answer
I have Nexus4 on Straighttalk with the same problem. I selected "Use this network as is" option. It worked for me

title: Restrict read access on certain folders

# Question
Title: Restrict read access on certain folders
I am looking for a way to limit read access for certain folders, for privacy reasons.

E.g. I want to have a folder that will be used for sensitive data. It shall only be accessed by a file manager app, office app, and picture gallery. And nobody else shall be allowed to read it (e.g. untrusted apps that may violate my privacy).

I am rooted, with CM11. Is there any existing solution for that? Or will it be a dirty hack?

I am thinking of creating a new user group, assigning the "private" folder to this group, and adding the apps (additionally) to this group. Is this possible? Or will I mess something up when doing this? I have a rough overview how the linux user system works, but I do not really know how the android users work in detail.

# Answer
Install an app like **KeepSafe**, which is optimized for pictures, or **Super Vault**, which you can store different types of files in. They encrypt your data and require a password to unlock, so those will probably be the best choices for you. They don't even require root.

If you want to go a step further, you can even install an app like **AppLock** to require a password to open a specific app.

**Alternative method:** You can install a file manager like **ES File Explorer** and *zip* a specific folder with a password, so no one can unzip the encrypted data without the password. *Keep in mind that you will have to unzip and re-zip every time you want to add/remove/modify a file.*

# Question
Title: YouTube app holds a long wakelock. What app settings can I change to keep it from doing this?
I am using an HTC Evo 4g with Android 2.3.5 Gingerbread. I'm trying to deal with apps which keep my phone from entering sleep mode, and the YouTube app is a major offender. With downloaded apps, usually the fix is to remove the app and find an alternative app that doesn't suck the battery dry. But I want to keep YouTube enabled so I can watch YouTube videos.

What settings for the YouTube app can I change to get it to not hold a wake lock for hours on end? Are there any device settings that I can change to help?

So far I have disabled "Preload subscriptions", "Preload watch later", "Improve YouTube", and "Notifications" in the YouTube app's settings, but the wake lock still occurs.

# Answer

You can use **Wakelock Detector** in combination with **Greenify** to block wakelocks and save a lot of battery.

**Update:** Since Gingerbread is not supported by Greenify, you can use **Wakelock Terminator** to stop the wakelocks *if you have root*.

# Question
Title: Avvio 792 4.2.2 Jelly Bean - ring time too short
Very new at Android, sincere apologies if asking incorrectly, just joined.

Ring time for incoming calls is only 15 seconds. Just enough time to go to voice mail by the time I dig phone out of backpack or break my neck running to get it, let alone find it.

Can apparently only be reset in 5 second increments up to 30 seconds by dialing **61\*local provider voicemail code**30#.

Service provider is Claro in Colombia. Appears to be due to no MMS available. Is this due to phone itself, or due to local service provider?

Can this be reset on the device itself? Is there anything in the code that can be modified?

Thanks!

# Answer

> Can this be reset on the device itself? Is there anything in the code that can be modified?

It is possible to extend the ring time, **but** you have to deactivate voice mail and call forwarding/divert for no answer (i.e. missed call).

> Is this due to phone itself, or due to local service provider?

I found that Claro Colombia is one of GSM network provider. It seems there is a "standard" for GSM network to have 30 second divert 'rule'1. Most telcos will follow such rule, although some may ignore it. From Wikipedia,

> In some networks there may be a limit of not more than 30 seconds before forwarding (i.e. "XX" can only be 5, 10, 15, 20, 25 or 30; all greater values, like 45 and 60, will result in the forwarding command being rejected and an error message returned).

Without voice mail and call forwarding/divert, the limitation will be gone, although most telcos still only allow ring time up to 40~60 seconds.

The most direct solution is to contact their service and ask if it's possible to extend the ring time before the call is diverted. A friendly suggestion is to put the phone at easier-to-reach place. Worse, you might need to find another provider that is suitable for you (off-topic here).

1 Based on research on many forums/articles such as this, though there is no legit reference.

# Question
Title: ZTE Midnight Memory
I just got a ZTE Midnight literally today and when I tried to download some of my favorite apps, it told me the memory was full. So I went in to see what was on my internal memory, and its already full from the apps the phone comes with, aka, apps that I can't delete. So I tried to set my default download location to my SDcard and after a completely failed attempt at googling how to do it, I decided to try asking about it on here. If somebody could give me a hand with this and possibly save me from breaking said brand new phone, that would be amazing. Thank you.

# Answer
You may want to root your phone to *debloat* it so you can delete all the unwanted system apps on your phone. Ask for this if the following does not help you.

**This might answer your question: from Installing to SDCard by default.**

This article at HowtoGeek describes a possible way utilizing the :

* enable USB debugging
* connect your device to your computer
* execute the command `adb shell pm setInstallLocation 2`
(or, new syntax, `adb shell pm set-install-location 2`)
* disconnect, done.

This command will set the devices default installation target to your SDCard. That doesn't necessarily mean *everything* gets installed there: only apps supporting this will go there, and devs can "overrule" this in their apps manifest if they think it's needed. From the linked API reference:

> Changes the default install location. Location values:
>
> * `0`: Auto—Let system decide the best location.
> * `1`: Internal—install on internal device storage.
> * `2`: External—install on external media.
>
> **Note:** This is only intended for debugging; using this can cause applications to break and other undesireable behavior.

For more details on ADB, and how you can e.g. get a minimal version of it to your computer (without the overkill of installing the entire SDK), you can take a look at the tag-wiki.

Some clearance on the installation process:

1. you find some app on and decide to install it
2. after you've clicked "install" and agreed on terms/permissions, the is downloaded **to `/data/local`**, i.e. to your . *You can't change that.*
3. when the download is completed, the `.apk` will be installed automatically. Where to, depends on multiple things:
    * if the dev did not specify the `android:installLocation` property in his apps `Manifest`, the app will be installed to internal story. Full stop, no other choice (see: API reference).
    * if this `android:installLocation` is set to `preferExternal`, and external storage is available, it will go there.
    * if it's set to `auto`, it again depends:
        1. does the app contain widgets, services, wants to start at boot, and several other things, it goes to internal storage. Full stop, no other choice.
        2. it goes where the devices "default install location" points to.

# Question
Title: Can I select which email address I use to respond in Lollipop?
I have multiple email addresses. I have one through my ISP, work, gmail etc.

My problem is that I'd like to be able to choose which address I use to respond to an email. For example, if my boss sends something to my gmail, I'd like to respond using my work email without copying and pasting the whole thing.

In previous versions of Android, there were different apps for different types of email accounts but in 5.0 the gmail app handles all email. Is there a way to choose the from address when responding?

# Answer
Not a Lollipop specific solution, more in general- works in other versions.

1. First you need to access your GMail account through your desktop browser.
2. Click the Settings cog in the upper right and choose "Settings".
3. CLick on the **"Accounts and Import"** tab/section.
4. Find the option labelled "**Send mail as:** (Use Gmail to send from your other email addresses)". Should be the third one down. Click **"Add another address you own".**
5. Follow the prompts in the popup to add your other email account (address, username, password, server, etc.).
6. Once finished, GMail will send a verification email to the account you're trying to add. Open up that secondary email account, open the verification email and either click the URL to verify or enter the verification code.

Now open up your GMail app on your phone (may need to reload it first). Try to reply to a message. If you look at the **"From:"** line, there should now be a dropdown arrow at the right. Tap on it (or the email address) and there's be a dropdown where you can choose your newly added account.

From the Google Play Music App, open up your Playlist section. Find the playlist you want to shuffle, and tap on the three vertical dots on the lower right. Choose Shuffle on the popup.

You can turn on Shuffle mode by first starting song from your playlist, and while it's playing, tap on the banner at the bottom that displaying your currently playing song. This will bring up Google Play Music's player interface, which has the song name scrolling at the top, album art in the middle, and the play/pause buttons at the bottom. Next to the play/pause button, in the lower right,is an icon that looks like two crossed arrows. That's the shuffle button. Tap to turn it orange and it's on. It will stay on even if you switch songs/albums/playlists.

**As per the chat I'm told that:**

* the arrow keys can be used to scroll documents, web pages, etc;
* the suggested wireless keyboard replaces the on-screen keyboard, thus allowing you to work with it on all the necessary input actions.

*I hope this helps you out!*

I have a Targus bluetooth keypad that I can connect to my Tablet/Phone and use it as a number pad. It has a Num Lock switch so it can also be used to input up/down/right/left and PageUp/PageDown.

It however depends on your device if your onscreen keyboard vanishes when you connect to a bluetooth device or not (my ICS CyanogenMod9 does hide the onscreen keyboard).

Price is OK, I got that for around 15EURO. Not sure how the availability is at your place. Just search amazon, et al. but be sure you get a bluetooth model and not one with a USB wireless adapter (like most Logitech accessory).

PS: The media keys also work nicely.

What you're looking for is an overlay with buttons to do the job, from what I can find here, is this, over on XDA. Button Key Saviour. (One Caveat Emptor - *you need root* \- but that's XDA for you)

If this does not do the job for you - please do let me know and I can program up an app that will show the page up/page down keys.

So feel free to contact me anytime :)

If you are using an Android device , you may check my app "Smart Scroll Tools" , which brings the possibility to start scrolling by a simple click (stylus) on a button; the scrolling continues until you touch (stylus) the screen again, and all directions are supported. Once you install the app , this feature will be available as a system-wide functionality.

# Question
Title: Phone app: what does the blue forbidden sign (with optional blue "A" in front) mean in the call log?
I have the following question concerning the Samsung Galaxy SIII:

When one taps `Phone -> Logs` it is possible to see the following icons:

* Incoming calls which were answered and received text messages (icon displays a green arrow pointing to the left) (clicking entry displays date and time call was received or text message was received and call duration for calls)
* Incoming calls which were not answered (icon displays a white arrow bouncing to the left off a red phone receiver) (clicking entry displays date and time call was received and displays the text "Missed")
* Outgoing calls (icon displays an orange arrow pointing to the right) (android phone app does not differentiate outgoing calls which were answered from outgoing calls which were not answered, but clicking on the entry displays call duration for calls which were answered or the text "Canceled" for calls which were not answered)

However, I am not sure what the following mean in the Phone application:

* icon displays blue circle with diagonal line through it (clicking on this entry displays a date and time and the text "Canceled")
* icon displays blue circle with diagonal line through it with blue uppercase "A" in front of it (clicking on this entry displays a date and time and the text "Canceled")

What is the difference between these two icons?

Thanks.

The five different possible icons I mentioned appear in the following screenshot (contact names and phone numbers scribbled-out, click to enlarge):

# Answer
* The icon that displays a blue circle with diagonal line through it in the Phone app's Log tab appears when the user receives a call and manually rejects it with a swipe when the phone rings. As soon as the user swipes to reject the call, the caller will hear the tone of the phone call change from a ringing signal to a busy signal.
* The icon that displays a blue circle with diagonal line through it and a blue "A" in front of it in the Phone app's Log tab appears when the user receives a call but the caller has been added to the reject list from the Contacts app. In this case the caller will never hear a ringing signal and will hear a busy signal as soon as the call is made, and the receiving party will not hear the phone ringing since the contact was added to the reject list of course. **The blue A in front of the blue circle with a diagonal line through it is most likely understood to be the first letter of the word *autorejected*.**

# Question
Title: Automatically restrict apps background data using Tasker
I've been using Tasker for a couple weeks after receiving this recommendation, and I have a few beginner questions. Here is one of them.

I've set up a profile to lock the phone after 10 seconds of darkness (cases where phone is in pocket or turned face down). I would also like to save some power by activating the "restrict background data" option while the phone is not being used. It's under *Settings* -\> *Power saving* on my phone (Samsung Galaxy S5).

<sup>(Click to enlarge)</sup>

My questions are:

1. Is this a good idea, or do the disadvantages outweigh the benefits?
2. Is there a way to toggle the *Restrict background data* option using a task in Tasker?

# Answer
"Restrict background data" seems to restrict apps from accessing the network unless they're in the foreground, i.e. visible on the screen.

On Tasker version 4.5u1m for Android 4+, I don't see anything relevant in the Net action category, which is where I'd expect to find something about network access. The Settings action category is just for showing settings dialogs, so it wouldn't be there.

You could turn that "restrict background data" setting on, and then auto-launch any application that you want to update/sync given a particular parameter (e.g. launch music app when headset inserted, only changed to something like launch google play when I'm signed into a wireless network). Basically you'd be using tasker to put something in the foreground, not switch the setting.

You can also limit syncing, which is one kind of background data.

# Question
Title: Is it possible to create 100+ tasker profiles from a spreadsheet?
I'm looking to create multiple tasker profiles that trigger based upon DOB of a client and send a SMS wishing them a happy birthday.

That's easy enough, but replicating the same thing time after time over 100 times is pretty time consuming. Does anybody know of a way to achieve this externally to Tasker and then just importing them in? I have all the DOB and names in a spreadsheet so I'm hoping it could be simple.

Or, is there a way for Tasker to check DOB in your contacts folder and auto send an SMS if the date matches?

# Answer
> 1 votes
Tasker imports/exports are usually in XML format. You can export your Excel file to XML, but it'll need a lot of formatting to become tasker-readable. The template is listed on the sidebar for r/TaskerFiles/.

If you have the DOB in the correct field in Contacts, you can trigger a task off your calendar (in Beginner Mode / Tasker version 4.5u1m for Android 4+ : Create a profile with State \> App \> Calendar Entry). You can select a specific calendar, and there's a calendar that just contains the birthdays of your contacts.

That's the trigger. After that, you'd need to retrieve the name of the contact (which should be contained in the calendar event title), match it to a phone number, and then disable the trigger so you aren't sending SMSs all day while it's someone's birthday.

# Question
Title: Recover data of app not on Play anymore?
Seems I deleted an app or a directory too much from my Android 2.3 phone. In particular I remember removing an app called App2SD or similar. Now, after booting the phone, I cannot see the apps anymore that were installed on the MicroSD card. However, I would like to access data from one app in particular. This app is called Epistle, and I was thinking about simply reinstalling it. However, it is not available on the Play store anymore.

*What strategy can I use to get access to the data of that app?*

# Answer
> 0 votes
Solved. I found a copy Epistle on the web, and installed it using:

```
adb install 2388.-Epistle_v1.2.1.apk

```

Now I can see old data again!

*Warning:* I was aware of the risk that during installation the app may reinitialize its database. If that had happened, then bad luck. The data was comprised of some notes that, while nice to have, would not have been terrible to lose.

# Question
Title: How do I get to the "Home" in Play Store?
I feel really dumb for needing to ask this. When I'm using the Play Store app, how do I get back to the main screen? Currently I hit "Back" multiple times to get there, but if I have done a lot of browsing, the navigation history is very long, so I have to hit "Back" many times.

Is there a quick way to get back to the main Play Store screen without using the Back button?

# Answer
> 1 votes
Whenever you navigate the Play Store using the app, each app page has a left-arrow just below the status/notification bar. I have just tested this to 20 levels deep, and the arrow brings you to one of 2 places:

1. Play Store home directly, or,
2. that account's navigation menu, including Store Home as the first option.

# Answer
> 0 votes
To get to the front page of Play Store, with a lot of history, it may be cumbersome and time-consuming to press the back key or the *up* key (the left arrow in the top-left). Below is an easier method. Note that this is only possible on devices after Gingerbread (**Android 3.0+**)

1. **Add** Play Store to your home screen from your app drawer. *Note: This is optional, but it will save you time in the future.*
2. After browsing for a while, open your recents by holding the **Home** button, or **Recents** button if you have one.
3. **Close Play Store** by swiping the thumbnail either to the left or to the right, or by clearing all recents, if you don't mind closing all the other apps that are open. *Note: Functionality to clear all recents may vary from device to device.*
4. Go to your home screen by pressing the **Home** button.
5. When you **open Play Store** again from your home screen, it will be back at the front page.

title: Uninstall app for all profiles

# Question
Title: Uninstall app for all profiles
On my tablet I have created restricted profiles for the kids. These restricted profiles have "app protection" enabled to prevent accidental uninstallation of apps.

Uninstalling an app that is enabled in the restricted profiles is quite cumbersome: I uninstall it in the owner profile. After this, it is still present in the restricted profiles. So I disable the app protection for all restricted profiles, then login into all the restricted profiles one after another, uninstall the app there, and finally I return to the owner profile and re-enable the app protection of the restricted profiles.

Is there a way to uninstall the app for all profiles in a single step?

I do not have root access on the device.

# Answer
> 2 votes
*Note: Depending on your device and ROM, you may have to disable app protection before trying this (thanks to Andrew T.'s comment).*

Try this:

1. Open the **App Info** screen for that app. You can access this from **Settings \> Apps**. *Note: Depending on your launcher, you may also be able to access it from your home screen. In the stock android **Launcher** and Cyanogenmod's **Trebuchet** (along with apps building on one or the other), you can press and hold the app icon in the drawer, as if you were going to place it on your home screen, but at the top, there are two options: **uninstall** and **app info**. You would want to drop the app on **app info**.*
2. There should be a button in the top right corner of the App Info screen, "*More*." After pressing that button, an option should be revealed to "*Uninstall for all users*." See below for picture.

You can read more about the *UserManager* at the **UserManager API page**.

title: Why won't JRD MMITest go away?

# Question
Title: Why won't JRD MMITest go away?
This app (which doesn't actually appear to exist on my phone) keeps popping up randomly on my phone. Its called JRD MMITest and seems to want to test the functionality of the phone.

It covers such tests as accelerometer, touch screen, radio, speaker, bluetooth, wifi, etc but all of that works fine without the app even testing for it.

In what I suspect is a related issue, certain phone features have also turned off from time to time... Auto Rotation being one of them and I noticed my Play Store app's data had suddenly been restricted on wifi. I have since corrected these issues with no further anomalies becoming evident as yet.

My phone is a Vodafone Smart 4 Mini (Model Number 785) running Android Jellybean 4.2.2.

I've completed the testing successfully and restarted the phone under the impression that this would prevent it from coming up again. (as per Annoying MMI test on Alcatel one touch evolve?) however the app keeps coming up randomly.

I don't know what else to do here, does anyone have any suggestions?

# Answer
According to tnagy on the topic of JRD MMITest:

> This is the manufacture test of your Android phone's internal components. It will perform a check on the main components like LCD display, sound, etc.

You should be able to **disable** the app if you do not want this app to perform regular checks.

1. From **Settings \> Apps**, slide all the way to the right until you see the *all* apps screen (not *downloaded* or *running*). Scroll down to **MMI Test** and click on it. *Note: On some devices it might be listed as **MMI Test II**, or some other derivative.*
2. After clicking **MMI Test** in your list of all apps, you should be able to **Disable** the app. This will keep the app on the phone, but it will not be able to run at all, even in the background.

If you want to permanently remove the app, you can **root** your phone and install an app like Titanium Backup, which can delete system apps, such as **MMI Test**.

# Question
Title: Galaxy S4 Battery Drain
I recently got an S4, and the battery drain is huge. I'm not even using it with a SIM card yet because it is that bad.

Over 10 hours, `Phone idle` used 36%, and time on was 10 hours 29mins. The screen used 23% at 9mins 20s.

Any idea how to make this battery last longer?

It's your apps and services running in the background. Try to kill as much proccesses as you can. I used to put different apps in pause mode just by hitting home button, and I noticed the battery draining like crazy.

I also killed lots of services in App Manager (All proccess tab). I found lots of useless services draining my CPU and battery. Try that.

# Question
Title: How do I install a custom ROM on a Prestigio PMT3677
I want to install a custom ROM like Cyanogenmod or similar on my 7" Prestigio tablet.

There doesn't seem to be any content on the net to explain what ROMS are compatible with this specific model and the steps to be followed to install a custom ROM on the device.

It's currently running Jellybean 4.2.2 but the tablet has extremely slow response times for most apps (and I have very few apps installed). Installing a custom ROM might make it a little faster and give it a nicer look.

I've already rooted the device using the same method as you would use to root the Prestigio PMP3670.

I don't want to just take a chance by installing just any ROM without following the right procedures for fear of bricking the tablet.

# Answer
Custom roms **must** be ported **separately for all device models**. Installing a wrong ROM on a device *even marginally different* from the one it's intended for **has the potential to brick the device permanently**. If you cannot find a ROM made **specifically** for your device model, you are out of luck.

# Question
Title: How untangle two Whatsapp accounts created with the same numer?
First, I installed Whatsapp on my Alcatel phone, with my whatsapp account ("son").

For my old mother, I bought her a big screen, cheap second hand Samsung Galaxy, (poor eyesight). That Samsung is blocked by the phone company (long history, don't ask); it can't make/receive calls.

I installed Whatsapp (via Wi-Fi) on her phone using my own phone number (stupid mistake) to get the audio check code. She got her own account ("mother"). It works almost fine, but I ("son") can't add new contacts because invite responses goes to "mother" account.

I changed phone number in "mother" whatsapp to her real working Nokia basic phone, but still doesn't work.

Short of deleting "son" and "mother" Whatsapp accounts, or buying a new SIM card for me, can you think another solution? I live 4 hours away from "mother". I don't want to lose 2 years of messages and contacts.

# Answer

You can save a backup of all messages you have, then going through settings - account you can either: delete the account then activate it again another time using the correct number for each phone. or use "change my number" and reactivate the account with the wrong number to the correct one

Title: No status shown below display name
When I look at the list of my Viber contacts, I see three different statuses which are online, offline and last seen at. However, there's one particular contact which doesn't have any of it, I mean nothing is written under the name on his contact profile on my phone. What does it mean?

He can't have uninstalled Viber cause his account looks recently refreshed. He has updated his photo along with his Line App. So what does this really mean?

# Answer
Viber has a privacy settings where you can hide that status

you can find that by clicking the "more" button... that is the three stacked horizontal lines, then choose settings then privacy. you get something called "Share 'Online' Status" you can untick that if you want to hide it. Note that you can change it once every 24 hours

# Question
Title: Causes and solutions "UIDs on system are inconsistent... I'm feeling lucky"?
*HTC One Mini 2/Android 4.4.2/HTC Sense 6.0/Not rooted/4 weeks old*

A couple of days ago i encountered this message on my phone:

**`UIDs on system are inconsistent`**

**`You need to wipe your data partition or your device will be unstable`**

**`[I'm feeling lucky]`** (button)

...and then ensued a long day of tech support & research which i wanted to share here. Web searching did not solve my problem directly, and while i can add a couple of insights that i didn't find elsewhere, i don't really have an answer. Many of the information i found was from people who had rooted their phones, and therefore not directly relevant to me - i am approaching this from an un-rooted phone

.

## Symptoms/history

Phone crashed while browsing HTC's blinkfeed, and restarted

It limped along for a few minutes and restarted again

Phone then gets stuck at white HTC/android screen and remains there (left for several hours) - ie cannot power off, screen remains on

Later, i discovered that you can proceed beyond this screen by ejecting the sim card - this then shows the lock screen (active background, time, date etc) but on top of this is the message UIDs on system are inconsistent... and one button which says "I'm feeling lucky". Whether you can press the button seemed to be allowed if you changed the position of the sim card - (ie if out, push it in, if in, eject it).

After dismissing the strange message, i am left with a black screen with notification bar at the top, and navigation bar at the bottom. No apps; no widgets. The notification bar was working, in that i could swipe down, enter settings etc. Further, if i received a text, i could then access my messages via the notification bar, but could not reply to a text because the keyboard did not load. Having used an app like messages or settings, i could switch between them with the bottom right navigation button as usual. I found that i could receive phone calls, and once done so, i could dial others by switching back to the phone app. This about sums up the functionality of the phone.

The other comment was that the phone could not be switched off. Holding down the power button and selecting power off simply resulted in a restart of the phone.

After further investigation with HTC technical support i found i could restart the phone in safe mode, but exactly the same process happens (ie restart, ejecting and re-inserting the sim card and agreeing to the "I'm feeling lucky" button to get back to the main lock screen).

HTC technical support wanted me to do a hard reset: this can be done in one of two ways, by software (an option under settings\>backup & reset\>Reset phone) or by hardware (holding down volume-down and power during start up. The software method had no effect on the described behavior. We tried this several times. The hardware method was unsuccessful, the phone simply restarted in safe mode.

HTC technical support finally admitted defeat, unable to think of something else suggested sending it in for repair. Vodafone tech support also offered to send a pack for returning the phone for repair.

All comments/further info from the community will certainly be interesting, but please also see below, as i did manage to avoid sending back the phone for repair as I did eventually succeed in the hard reset.

# Answer
## A Solution

On reflection, my thoughts were 1) this seems like a software problem, possibly malware of unknown origin and 2) it seems to be interrupting the power-cycling of the phone.

Therefore, before committing to sending the phone out to either HTC or Vodafone to look at, i tried my own hard-reset of the phone. Without access to remove the battery, i simply discharged the battery completely (wifi,GPS,Bluetooth,NFC,active call).

Now, plugging in the phone to charge, i found that i could enable a hard reset (holding down power and volume down) i get a basic text interface with option to do a hard reset. This was sucessful. Clearly this is a much stronger version of the factory reset than via the menus.

My phone is now set up again and working happily, and i dont need to send if off for "repair".

## Possible causes

My feeling is this was a piece of malware, although i have no direct proof. As a resource to assist others, below i list the most recent apps i downloaded. /Trigger: SMS Plugin/NFC ReTag FREE/No One Dies/Rightmove Property Search/Contacts Optimizer/Google Keyboard/AnyTag NFC Launcher/Proxy Settings/Aix Weather Widget/Bright Weather/

In hindsight, i accept that some of these are from lesser-known sources, albeit all acquired via the play store, i didn't pay close attention to the permissions.

## Summary

My primary motivation for posting here is because i failed to find useful advice yesterday when i needed it. Many others have posted about this message, some also suspecting malware, but most say a factory reset solved the problem. I hope to add to the situation the following new pieces of information

1) Eject and reinsert of the SIM card to proceed when frozen

2) Running the battery down as a method of doing a hard reset, if the other method fails

3) A list of apps i recently downloaded, might help point towards a possible source of malware, albeit useless until compared with other users who encounter the same problem.

Using a dual sim smartphone is the same as a normal one except for:

I always had these problems with my old phone. Most of the times this helped:

1. Go to Device Manager right click and choose update driver software
2. Choose to search for drivers on your pc
3. Click Search and go choose: "Android SDK Path"\extras\google\usb\_driver

If that doesnt help, repeat step 1 and 2 and press "choose from list". Then choose Medium and choose "Android SDK Path"\extras\google\usb\_driver\android.winusb.inf. Then you should be able to choose "Android ADB Interface". Click next and press yes and it should install that driver.

Hope this helps you, cause i know how frustrating those problems can be

Title: formatted tab 3 10.1 and cant install android from twrp
got a problem with my samsung tab3 10.1 (5200), installed twrp and rooted the device and after that i formatted it in twrp to install a fresh android on an empty tablet. But install couldn't work , the installer couldn't make directories data and others so the install did not work ( took about 2 minutes) but at the end it says succesfull. It cant boot past samsung logo because i think nothing really installed. Anyone has an idea to try and install in another way ? I'm trying to instal cwm now but says md5 hash invalid and same with the twrp file which is on the device.

# Answer
already found the problem guys, after the format it sayd you best reboot the bootloader so i did that and then it could read and write, it's up and running without the latest offcial update that crashed a lot. rooted and deodexed whatever that means. grtz

Title: Huawei Y330 bricked
I have a problem with my y330 device, I rooted my phone and then I tried to install CWM but when I rebooted my phone, it started to reboot gain and again and I can\`t enter the recovery. What can I do? Thanks

# Answer
Download the firmware suitable for your country and device, flash it with flashtools (simply turn phone off and when you have flashtools ready, connect the USB cable to phone (better try first to let windows install proper driver)) search for vcomm driver if win fails.

Title: HTC Desire - Problem writing to /system
I have an HTC Desire HD Android device. I rooted it with SuperOneClick. I get a # prompt in terminal. adb remount fails. I'm able to remount /system with

```
mount -o rw,remount /dev/block/mmcblk0p25 /system

```

I can now make changes to /system.

The problem is that my changes are erased when I reboot the phone. This is true even if I create a small dummy file, e.g. derf.txt

Also any new apps that I install go in /data/app while the pre-installed apps are in /system/app.

Output of mount is:

```

```

Has anyone seen this? Can you explain why my changes get wiped out when I reboot the phone?

Thank you very much!

Instead of

```
mount -o rw,remount /dev/block/mmcblk0p25 /system

```

try

```
mount -o rw,remount /system

```

The problem is (was) that HTC apply a software write protection to `mmc` partitions, some workaround exist (wp\_mod.ko) but being a kernel module isn't handy.

ps: on old HTC 2.3.x the corrent syntax for `mount` need both the device and the mount point.

# Question
Title: Restore Google Authenticator on New phone without Root
I have ~8 logins that use Google Authenticator (Google, FB, Bitcoin stuff, etc). I made a backup of my Authenticator app/sqlite database before moving to my new phone. How do I restore the database/settings on my new phone without root?

# Answer
There's a walkthrough on exactly this topic here: http://www.howtogeek.com/130755/how-to-move-your-google-authenticator-credentials-to-a-new-android-phone-or-tablet/

Essentially, it amounts to disabling two factor authentication and re-enabling it, or for services like Google, using their "replace old 2 factor with new 2 factor" service. It is also possible to extract an sqlite database of your credentials, if you have adb and can access the phone that way, which I believe is possible without root.

# Question
Title: force headphone mode
When I plug in the 3.5mm jack and play back media, headphone mode keeps toggling, resulting in audio cutting in/ out every second or so.
Is there a way to force headphone mode or disable the 3.5mm jack detection?

I tried a couple of apps and searched the web but people seem to want to force speakers rather than headphones, so no luck.

(Android 4.2.2 Samsung Galaxy Tab 3 Lite)

# Answer
First off, you require root. Then Install Xposed Framework and Install an app ( forgot the name but do a quick google search for it and you will find it ) which lets you override your deafult actions when certain things happen like plugging in the headphone. Then you can set that action to anything you want.
