Clear App Cache/Data

The first thing you should try is clearing the cache for your camera app. In the phone settings, go to the applications manager and locate your camera app (the same screen you would use to uninstall the app). If your camera app is built-in, you may have to navigate to a tab that shows all apps installed, not just ones installed by the user.

There should be a button called Clear cache. Click this and then try opening the camera app.

If it still crashes, go back to the same screen and click Clear data. This will not delete your photos; it will reset the camera app settings and return it to the initial state when it was first installed.

Use a different camera app

Try installing another camera app from the Play Market. There are plenty of free ones available. If those work, perhaps your camera app is simply buggy or doesn't work with your device.

If other apps still can't access the camera, you may have a deeper problem.

Factory Reset

As a last resort, you can reset your device to factory settings. Make sure you back up any important data to your computer or to an external SD card.

Re-flash Rom

If a factory reset doesn't do it, you'll have to delve into deeper waters. Look around on XDA Forums or other places on how to flash a Rom to your device.

Replace Hardware

There is always the slight chance that your hardware is physically damaged. In that case, you'll just need to replace it or live without a camera.


The question does not only apply to android phones, but to all mobile devices. Our mobile devices use EMF to communicate. Mobile phones are, by definition, devices that can detect EMF since their ability to communicate depends on radiofrequency fluctuations in electromagnetic fields.  Our devices, especially smartphones, which are extremely reliant on internet services emit a huge amout of EMF radiation. That should imply that mobiles can precisely detect and manipulate EMF, right? No. Our phones are designed to work with only specific frequencies, from about 800 to 2.2GHz, so it is quite unlikely that a mobile phone can detect general fluctuations in EMF.
Now, the creator of the app might tell you that it uses magnetic sensor, and you might think that EMF can be detected using a magnetic sensor, since it is also (partly) a magnetic wave, but you cannot. EMF exists when a wave has both electric as well as magnetic parts.


Google Play support says:

You can only change your Play country once per year.

When you change your country, you won’t be able to use your Google Play balance that you have in your old country in your new country.

So, avoid Google Play and use another market app. I suggest either:

APKPure
Aptiode

Both allow auto-updating apps.

Samsung Galaxy Nexus Bootloop. Cannot format or write data

So after searching lots of forum, chatting with experts in XDA, I found out that:

  Samsung used a cheap substandard emmc.

I have tried everything from adb, Odin to jtag. The emmc just died,no way to fix it.

First there was this awful lag issue : Galaxy Nexus GSM bad eMMC chip type V3U00M phone is almost unusable

Later within 2 years, emmc will die and you will stuck with bootloop issue :
Galaxy Nexus GT-I9250 with hardlocked NAND ?!? need help !
Galaxy Nexus S (i9250) stuck in reboot loop - gets to OS loading and restarts

Almost all of us with V3U00M chip and other defective mmc chips would have now got there emmc fried.

  What to say, on my side I'm blacklisting Samsung, this phone has been a joke for me since the beginning (the fstrim bug has been a nightmare), if you dare you can try to replace the board.


Sony Z1 Compact: will encrypting my phone disable the camera button?

I am pretty sure that you wont lose the functionality of lock screen camera. But check once before encrypting because you need to hard reset/repair to decrypt xperia phones.


Flash CM on encrypted phone running stock Android

In short, you will most likely lose all your data, because:

You have to unlock your bootloader when you install a third party ROM. Unlocking the bootloader will erase all your data.
The new installation might not be able to decrypt your data.
Even if it would work, it is still not recommended to keep all the data when installing a different version or make of a ROM.

You should make a backup of all your data, then format your phone.


why there is exclamation mark on wi fi. I am facing problem after upgrading to lollipop 5.0

in lollipop , '!' is shown usually when wifi is connected but unable to access internet for reasons like Sign-in into ISP webpage,etc .

i suggest u to turn off wifi router power supply and turn it on after 10 seconds,
this solved same problem for me


Can I run the same app simultaneously with two users?

Yes it should be possible with multiple user profiles.


How can I configure Google voice access so that I only have to say "hey Google" once?

I've just updated the voice access application to the version 5.0.35 and the issue is fixed: there's no more timeout, i.e. voice access stays activated until one closes it.


This is the method I use for finding important apps which have to fit certain requirements:

Make a list of all the features you want.
Have some music in the standard music folder which the standard music app uses. Don't have too much music as it may take a new app a long time to read it all.
Find an article which compares popular music players like "10 best android music players". Popular ones will be most likely to have lots of features.
Download the music apps mentioned in the articles.
Start it and test it to see if it has the features on your list. Keep a record of the ones that meet most of your requirements, as there is a chance you might not find exactly what you want.


Recover photos from locked Android (Galaxy S5 Verizon)

If adb is on then you have a chance to recover data from the device.

Install adb and fastboot drivers in your Computer.
Connect your phone with an USB cable
Open terminal and enter adb devices

If it shows your device then you can extract any file by entering adb pull path/to/file


Can I connect two bluetooth device to my tablet?

I honestly thought that only one device could be connected at a time using Bluetooth. In an attempt to prove my point I tested connecting multiple devices simultaneously to my Samsung Galaxy Tab 4:

Sure enough I was able to stream music to my Milwaukee speaker while using an Apple mouse and keyboard- all connected at the same time. Granted, there are probably still instances where this might not work depending on devices and most likely would only be able to stream music to a single device, but it worked perfectly in this case.


rooting device stops usb-host-mode working

According to this forum thread and this bug report, it seems that there has been a regression regarding USB modes in the kernel used in 4,3 (The version that you posted).

It seems that there is a problem with that kernel specifically, but nothing else in the ROM, that breaks USB Host Mode in some cases. There are a few possible solutions:

Flash a different Android version. An update to 4.4.2 should fix things (as it did for you).
Flash an alternative, third-party kernel and try your luck. You Mileage May Vary.


Backup/restore question for Moto G XT1033 converted to XT1032 GPE

Moto G XT1033 as it seems from this question supports OTG, which means you can connect a pendrive using an OTG cable and store complete Nandroid backup in it through the recovery.

  Will I be able to return to system with Phone (sim) and Play Store apps working through the "system" backup?

I cannot comment anything about Baseband/IMEI issue, but you will definitely lose Play Store apps since they are downloaded and their data stored under /data, which you're not backing up here.

On a side note, the device has good amount of Internal Storage available; can you not make space enough to store the backup in it?

May be you can try making a backup of /system only and then pushing it through ADB into the PC. Do the same for /data and /boot now. ADB will work in Recovery.


Can an android phone be tracked on find my phone app etc if the sim has been removed and had an factory reset?

Google help says

To find, lock, or erase an Android phone, that phone must:
Be turned on
Be signed in to a Google Account
Be connected to mobile data or Wi-Fi
Be visible on Google Play
Have Location turned on
Have Find My Device turned on

After a factory reset, your account is removed from the phone and without SIM it's not connected to internet.
So no, it can't


Can't set picture in Android Quick Setting

As of some version from may, the contact option was removed mysterously by google. Maybe they are going to reintroduce it by some other mechanism. But for now, you'll need to download  the g+ app prior to may (you can get legit apks from apkmirror). Then enable the contact sync from that. Post which, you can upgrade to the latest g+ version


Is it reasonably safe to use PIN code for encryption?

I think I have found the solution. Check this link. It's a hack and it requires a phone to be rooted, but it does allow you to use alphanumeric password for encryption and PIN for screen unlock.


Can I save a "star-hash" (*#) code as contact?

It is not meant to be dialled as an ordinary contact number

Quoting from this answer

  What the dialer really does when you enter the code is extracting the number between *#*# and #*#* and then broadcasting the following intent....

Saving it as a contact and trying to dial means it is a treated as a regular, valid number

Which is rejected by the service provider , since it is not a valid number
Expected code is not launched since the corresponding intent is not triggered

You can try creating a shortcut to the intent using an app like this or apps like Tasker

Android 6, delete file from /data/user/0/

There is no way you can access the /data partition unless you are rooted.

So, you need to root the device again to delete it..

Or, if you have a custom recovery installed, then you can just easily delete it, like:

For TWRP, open 'Advanced' and go to 'File Manager' and delete the file.
For CWM/Philz, just use (flash) the AROMA Filemanager Zip and browse & delete the file.
Or else, you could create a flashable zip to delete the file from the exact file location, or you could do it from the Terminal of the custom recovery (if it provides one)

Or else, if you don't have custom recovery, and if you don't want to root, the only way would be to factory reset (you might want to take backups before that).

  PS: I tried mounting the device storage to my Ubuntu 16.04 machine, but could not find the folder.

The device storage (internal storage) shows the files under /data/media/0, so you won't see it there..


You can follow this guide to bypass the activation screen.  It requires reverting back to RC29 ROM (downgrading back to 1.0), and having ADB and HTC drivers installed on your PC.

The reason for installing RC29 is that this version has a flaw that treats anything you type as if it was typed into the Terminal.  You will be exploiting this flaw to enable ADB access and bring up the Settings menu, from which you can enable WiFi and activate the device.

  With a Sim Card installed in your HTC G1, turn on the phone.
  Plug your T-Mobile HTC G1 to you PC USB and Install Drivers on the Windows XP Machine.
  Once it ask you for registration type on the keyboard the following:
  [enter]
  setprop persist.service.adb.enable 1
  [enter]
  *Even though you don’t see what you are typing, but you are actually
  executing a Command on your G1 to Enable USB Debugging in Settings.
  You will notice that the command worked, because Windows XP will recognize a new Hardware Device. “HTC Dream Composite ADB Intefase”. Install the driver by pointing to the folder where you downloaded the USB Drivers.
  Unzip the ADB Tool software into the “c:\adb” Windows XP folder.
  On Windows XP, click Start -> Run -> cmd” to Command Prompt
  Type c:\adb devices (If your Device is Connected u will see it)
  Type c:\adb shell (You will see a $ sign) Just Copy & Paste this into Command Prompt:
  am start -a android.intent.action.MAIN -n com.android.settings/.Settings
  The settings screen will appear on the HTC G1 Phone. Now switch on Wi-Fi, connect to the WiFi network you have and connect to the Internet.
  Now you can either Login with your existing account or create new account with Google.

After your G1 is activated, you can then flash a custom firmware (e.g. CyanogenMod) or a pre-rooted stock 1.6 ROM that will allow you to re-activate your G1 over WiFi without resorting to exploits.


You can try Handbrake - a multiplatform open-source video transcoder. It has quite user-friendly graphical interface, and supports different device profiles (you can roll your own as well). As to what settings to use on your Xoom: Here someone managed to find the correct settings to make their Xoom play the transcoded video.

Some extra googling would probably give you additional information how to set the device profile in Handbrake -- seems a lot of people are trying to transcode video on this tablet.


Downgrade nVidia Shield to Android 4.4 KitKat

One way would be to flash a factory image to your tablet, which would restore it to the state it was when you first bought it.

Depending on your model (wifi, or wifi + lte), you can find official factory images to for the SHIELD tablet on this nvidia website:

https://developer.nvidia.com/develop4shield

Following the relevant links, you will get to a website from where you can download the factory image. The bundle should also contain instructions. Hope this helps.


Is there a downside to keeping the HDR mode on my Moto G phone camera always on?

No downside to it (barring some scenarios)

HDR increases the dynamic range between the darkest and brightest colours in your photo and there's no downside to it apart from lag (that may be fixed by using camera apps that respond faster -you would need to experiment)

But it's not a silver bullet to increase the quality. Some situations where it spoils rather than help :

If the picture you wish to take isn't already brightly lit with a bright spots and dark ones (like shadows)  , it's better to avoid HDR. In this case, HDR photos look artificial. As Izzy pointed out in comments, pictures that don't have much contrast between dark and bright (low dynamic range) don't come out well. HDR can only enhance range not create . Try taking a picture indoor with subdued lighting with HDR to see how poorly it comes out.
If you or the object is moving, the lag may cause blurry photos (HDR takes 3 photos – normal exposure, under-exposure, over-exposure – and combines them. (In professional cameras it takes even 7 photos). If the object moves in this process , it becomes evident as blur. This is called ghosting (anti-ghosting algorithms may be able to compensate, but they have their limits). Same result if you move while taking the shot.
Also if your picture has bright colours already like close up of a bunch of flowers in a garden, it adds artificiality.

For a technical understanding see this from our sister site What is HDR

You may feel that HDR is not kicking in when it is required, but then it is the software which decides when it should, so better leave the judgement to it ! (Setting on Auto)


A friend gave me a backup he used for his Samsung Galaxy On5, How do I use these files to 'restore' my Samsung On5?

Boot in TWRP and hit Restore. It will show a list of backups, select one and you'll see a list with  System, Data, Boot. Make sure all the boxes are checked and swipe the bar to restore. The restore will take a few minutes, but when it’s finished, you can reboot your phone back into Android. If it asks you to root, be sure to tap “Do Not Install” if you don't wish to.

Flashing a zip file:

Tap on Install . browse to the location where you saved the file 2016-09-21_twrp_on5ltetmo_system_data.7z.
Now at the bottom of the screen, do a swipe on the Swipe to confirm flash option to begin flashing. Reboot the device when finished.


What are the technical reasons that SMS is not backed up in a full ADB backup?

Basically what adb backup does is in lay mans terms what a.iso file does for the System.It creates an image file this image file is created as backup.So when ever there is an issue/failure the ROM is restored with this image file.

During the adb backup it will have restrictions due to which it does not backup the contacts,SMS.(You might observed this that it also leaves the contact backup as well.It's hard coded in the OS based on the linux on which Android OS is built).

The contacts,SMS are protected so the ADB backup is not able to backup these two.In order to backup even these you need to root the device.After rooting the device you are indirectly removing the protection so after a root Complete Backup is possible when compared to pre-root where 80% is achieved.

Rooted Android device and more regular updates?

Generally, if you're talking about updates for any ROM, then you should know that it doesn't matter if you're rooted or not to get regular updates.

Moreover, rooting modifies your /system partition, due to which OTAs (for stock ROM) will fail to install, because nowadays most updates are Block-based OTAs.
So, for successfully installing official OTAs, it's better not to root your phone or use systemless root.

You're not getting regular updates because maybe Samsung hasn't yet released any updates for your device.

But if your phone is rooted and if you have flashed a custom recovery, then, as you said, you can install any custom ROMs with active developers which might be getting regular updates.
As @Tamoghna said, you can install ROMs like CyanogenMod which might provide daily updates.
You can also check for CM daily updates using apps like CyanDelta Updater (as said by @Firelord) which provides delta updates of minimal size.


A simple, although superficial, solution would be to manually change the cover cover image (download it using a web browser and set it as the album cover). The following link has instructions on how to edit metadata and album art.
https://support.google.com/googleplay/answer/1100174?hl=en

If the problem persists with other songs in the future, you could try using a file managing app to solve the issue by searching for and deleting the image you are seeing (might be a leftover thumbnail somewhere or in the Google Play Music folder).


What is the diff between the Media transfer protocal and Picture Transfer Protocol

MTP is the better option in most cases, since the protocol is actually designed for this use.

PTP is offered as an alternative since Macs don't understand MTP by default (you need to install "Android File Transfer" on the Mac to make MTP work). This protocol was designed for PCs to access photos from digital cameras, so it can only access the photos on the phone, and it might trigger a photo management app on the PC instead of a file manager.

To learn more about why MTP was introduced, see my answer to Why is Android File Transfer necessary?


G1 Misbehaving -- can I (should I?) reinstall donut?

I'd actually recommend upgrading past Donut, since there is a great custom ROM community for the G1.  For example, this looks like the best Froyo ROM for the G1, but you can look around XDA's Android Development forum (specifically the ROM Bible thread) if you want to find out more first.


Can I track a deactivated cell phone that is using a textnow app through wi-fi?

It appears that TextNow can provide some potentially meaningful details to law enforcement.  It is however unlikely they would comply with a request directly from you.  Their info page is here: https://supportfree.textnow.com/hc/en-us/articles/204431979-Law-Enforcement-Subpoena-Requests

If you have not yet involved the police (and if you are in USA requested an Amber Alert to be issued) this would most definitely be the time to do so.  You'll need the authorities to request this information anyway, and they will have their own ways of trying to locate them which may be far faster than getting info from TextNow.

how to reset the phone pc after too mant pattern attempts

There are multiple ways to do this, most of them requiring adb being available on your computer:

How can i do factory reset using adb in android? gives this solution:

adb shell
recovery --wipe_data

How to Hard Reset or Factory Reset and Format Android Phones and Tablets gives detailed instructions on doing this with fastboot (including setting up your computer for that). The command finally doing the job is:

fastboot erase userdata

Doing that, I'd recommend to also include a fastboot fastboot erase cache (recovery --wipe_cache if you use the first approach).

If you had setup other means of accessing your device's command line interface from your computer (e.g. SSH), you can use the first command (recovery --wipe_data) from that shell as well – without the need of ADB/Fastboot.


First, AFAIK, "Notification Service" makes reference to receive notifications in Telegram about every new update (changelog or "What's new"), as well as another announcements which Telegram staff may consider important for you to know via Telegram chat.

Second, Android Lollipop has a new way to manage notifications per app. Enter Settings screen for your device and follow these steps:

Is it possible to access data while a device is on bootloop?

USB DEBUGGING CAN BE TRIGGERED BY PULLING OUT THE BATTERY...

If you have a built-in battery, You need to force a reboot by holding all the buttons on the device simultaneously for 30 seconds...

Try to remove the battery and replace it,   or force reboot ...

This will or should enable ADB Until boot logo starts to loop .. It will only enable it for enough time to check the settings and then disable it.... This means you can only run one segment of adb commands, So type them out first or just paste the following in CMD with ctrl+v

adb wait-for-device
adb pull /data


android.database.sqlite.SQLiteException: Can't downgrade database from version X to Y when running an app

[...] android.database.sqlite.SQLiteException: Can't downgrade database from version 7 to 6

This is caused when an app tries to downgrade an SQLite database from newer version, but failed since the code handle that is not implemented. (For more technical explanation: Can't downgrade database from version 2 to 1 even after fresh install and re-run).

This can also happen on Android Marshmallow (Android 6.x) or later when the data is backed up and restored after doing factory reset, leaving the data with newer version, but the app in older version.

What the user can do:

If the user wants to use the existing database: they have to find and use the version of the app that is using the current (7)/newer (>7) SQLite database version. Usually this means the user needs to update the app to the previous app's version (before the factory reset) or newer one (latest from the Play Store/developer's website).
If the user doesn't care about the existing database: depending on the database location, they can remove the database by e.g. deleting the file manually (probably need root access), cleaning the app data, etc. and let the app recreate a new database with older SQLite database version (big potential of data loss from the previous database).


You can buy a OTG USB cable and plug in your wireless keyboard and it works like a charm. I tested this in many ways. Just like the wired keyboard and mouse, it pretty works the same.

Note: some devices may not be compatible with this method but check with your manufacturer to see if it works.

Hope this helps.


Turned out that apparently on g+ the albums take the date of the most recent picture of that album, while on picasa web album there is a date for the album, I don't know why but sometimes the date for the album on picasa is the same as the one on g+, others times is simply the date when you created the album.

Anyway it is possible to change that date from the web interface of picasa by selecting an album and editing his property, It's a bit annoying if you have a lot of them but finally now I have all my picasa album properly ordered in my gallery on android. :)


How to delete photos ONLY from google photos backup?

You can uninstall the "Google Photos Backup" from your device or simply sign out from the account in the Photos app. Then go to the web-version of Google Photos (photos.google.com) and delete the photos.

Go to photos.google.com and login using the Google account you're
using on your device.
Place your cursor over items you want to move to trash. At the top
left corner of each item, click the select icon . (Or hold down SHIFT
to select a range.)
At the top right, click the trash icon.

I tried it personally (after signing out in the Google Photos app) and I'm sure it won't delete the photos from your phone.

Can i recover data from a Nandroid Backup without the original device?

That would indeed be possible. There are several apps which are able to extract parts of a Nandroid backup, e.g. Titanium Backup or ROM Toolbox.

Apart from that, depending on the format used by your Nandroid backup, you can either mount them as loop device (disk images) or unpack them (tarballs) to invesigate/access all contents.

For further details, I'd recommend a look at our nandroid tag-wiki – and especially follow up to:

How to check if bootloader is unlocked mediatek device

There is a great deal of ambiguity and misinformation in the previous answer(s) above. The root cause of this is ambiguity inherent in the words "flash" and "flashing": some people use a "flash tool" to "flash" .img or .bin files, others use a "custom recovery" to "flash" a .zip file, and still others use the bootloader to "flash" a .zip file.

Mobile Uncle MTK Tools (mentioned above) is software used with .img and .bin files, but there are others such as the so-called SP-Flash-Tools (SmartPhone Flash Tool). These tools are typically Windows, mac, and/or Linux programs. (and btw the correct word in this case is "download," not "flash").

When using a recovery to flash an update, the code that does the work sits in the recovery partition itself, and the user controls the process via some sort of GUI on the phone that the recovery displays.

When using the bootloader to update the phone, there is a special-purpose client called fastboot that lives on a computer which is connected to the phone via USB. Fastboot is also the name of the protocol that this client speaks over USB  with the bootloader code on the phone.

With those three things understood, it's easy to see what's going on:

If you use a flash tool to download some .img or .bin file to the phone, then you don't use any code in the bootloader at all. So whatever it means for the bootloader to be "locked" or "unlocked" doesn't matter (since you're not using the bootloader)
If you are using fastboot and the bootloader, then unless the bootloader is UNLOCKED, you won't be able to install ANYTHING but a bona fide uncorrupted factory-approved update file. That's what it means for the bootloader to be locked -- if you tell such a bootloader "Fastboot flash mywacko-update.zip" or anything similar, you'll see an error message and failure. Because it's locked.
Now if you use a recovery to update the phone, you might think that we are back in the 1st case -- you're using the recovery and not the bootloader, so it shouldn't matter if the bootloader is locked or not. Although the logic is unassailable, the fact is that the stock recovery of any Android that ever lived contains code which will cause the update to fail unless the update is a stock factory-approved one. In other words, it's a fact that if the bootloader is locked, you won't be able to use the recovery to install something non-standard either.

But it's perfectly supported to take a flash tool and download a CUSTOM recovery which is not stock -- where one important feature of the custom recovery is that it just doesn't care about the locked/unlocked status of the bootloader.

If you do this, your custom recovery will "flash" anything you ask it to, .but you STILL won't be able to  use fastboot and he bootloader to flash anything non-stock. Because the bootloader will still be locked.

Finally, to answer the question about how to verify if the bootloader is locked or not:

Boot into the bootloader (sometimes called "fastboot mode"), connect the phone via USB to a computer that is running fastboot, and type the following command:

  fastboot getvar all

If you're lucky, among the many lines of output you get will be ones such as:

(bootloader)    unlocked: no
(bootloader)    secure: yes

Strictly speaking, I believe that locked/unlocked just means that: it can not be changed. The bootloader is "secure" if it will only install factory-signed images. That being said, I have never seen any combination but two: unlocked and not secure // or locked and secure. (As a final comment, the value of the  "secure" is usually referred to as "s-on" or "s-off")


You don't have to uninstall, when you install an app already installed, you have to use adb install -r. (for more help, juste type adb)

To uninstall an app, you have to use adb uninstall package-name (e.g. adb uninstall com.example.app).


Try this:

Setting > Data usage > (Data usage Action bar menu) > uncheck 'Restrict background data'

hoped it helps.

Bootloop issue and can't go to recovery mode

The Asus Zenfone Flash Tool is no official Software, furthermore it looks like this tool is using fastboot (which usually works on previously unlocked bootloader only)

for fastboot.exe download platform-tools and open cmd.exe. navigate to platform-tools folder with cd now you can type

fastboot reboot

if bootloader is already unlocked, you can also wipe cache partition and see if this fixes your boot problem

fastboot format:ext4 cache

you can also boot into recovery from fastboot and then install firmware update.zip. this should even work from TWRP as long as you don't flash recovery.
do NOT allow modifications of system. just wipe cache partition. try to reboot into system from menu. if still not booting, install firmware update.zip

fastboot boot C:\platform-tools\twrp-3.2.3-zenfone3-20180806.img

for locked bootloader you can download Factory_Phone-userdebug.raw emmc image which contains GPT partition table and all partitions. (from linux it is possible to loop-mount this image with kpartx  and split into partitions, but this is out of scope)

WARNING: all data lost
this will flash the entire device, be aware this deletes all your personal data. make sure this is the right phone model.
download CSC_ZE552KL_13_13_1_36_M2_6_7_P7_userdebug.zip.
it seems no flash tool is needed, it is maybe working from fastboot directly.
connect usb cable in fastboot mode and just run flashall_AFT.cmd

Qualcomm Devices usually can be flashed from EDL mode with QPST.
found a site with some Qualcomm EDL Programmers maybe one of this works for your device
Qualcomm_Factory_Loader_MSM8953_Lenovo.mbn
Qualcomm_Factory_Loader_MSM8953_Xiaomi.mbn
Qualcomm_Factory_Loader_MSM8953_Xiaomi_2nd.mbn

for EDL mode install Qualcomm HS-USB QDLoader 9008 Driver

for EDL mode you need to find Test Point

The following is just an example to illustrate the process and not valid instructions

For further documentation refer to alephsecurity there you can learn how to flash devinfo which unlocks bootloader and gives availbilitiy to flash custom recovery TWRP

basically you need the following files (most of them are included in QPST)

fh_loader.exe
QSaharaServer.exe
prog_emmc_firehose_8953.mbn
rawprogram0.xml
patch0.xml

the xml file has instructions for flashing partition, for example TWRP (not the right size/offset)

<?xml version="1.0" ?>
<data>
 <program SECTOR_SIZE_IN_BYTES="512" file_sector_offset="0" filename="recovery.img" label="recovery" num_partition_sectors="131072" physical_partition_number="0" size_in_KB="65536.0" sparse="false" start_byte_hex="0x1c200000" start_sector="921600" />
</data>

QSaharaServer.exe is used to initialize firehose with on the already to COM port connected device in EDL mode

QSaharaServer.exe -p \\.\COM10 -s 13:prog_emmc_firehose_8953.mbn -b tmp\"

fh_loader.exe is responsible for flashing the instructions from xml file

fh_loader.exe --search_path=tmp --port=\\.\COM10 --sendxml=twrp.xml"


Smashed screen on Xperia Z3, need to download data without touch capabilities

I have a phone with smashed screen as well and need to recover photos and videos. Searching around I have found several places where they mention using OTG (On The Go) USB cable to hook up a mouse and keyboard, also you can possibly hook up the phone to HDTV as explained here:
http://androidforums.com/threads/broken-screen-no-backup-and-need-your-data-try-this.841614/

I am yet to try the methods described as I need to buy the necessary cables first.


Firefox version 21 installed easily but greasemonkey won't install - error saying not compatible with ver 21

The error message in this case is misleading: it's not that Greasemonkey is incompatible with that version number, rather that it's incompatible with Firefox for Android. The extension mechanism in Firefox for Android is somewhat different to Firefox on desktops, so add-ons for desktop Firefox won't work (in general) on Android.

To find out if/when Android support is planned, or to help out, you could start by contacting the gresemonkey-users mailing list.


"There was a problem parsing the package" when uninstalling an app

This parsing error appers when either:

The APK file is corrupted (unlikely if you're downloading from the Play Store)
The APK file is not compatible with your Android version (again, unlikely if the Play Store works fine for other apps)

If the APK file is not provided by the Play Store, it is likely that either of these errors occur.

How to open an URL in Chrome Incognito Tab by launching the Incognito Activity?

It seems it's impossible, as per the answer of @bmdixon :

  I don't believe this is possible. According to this Reddit post, it is not possible when writing an app as the Chrome code ignores the request if it is not Chrome initiating it, so an app or user cannot trigger the incognito tab. I assume the same applies when trying to launch the activity 'manually'.

    So what these are doing, is checking whether the intent should be ignored based on whether it is the user or chrome performing the action. They make this determination based on whether there is a token from a signed Google app. So unless there is a way to trick find that token and figure out how to attach it to Tasker I don't think it'll work.


I imagine you are talking about Exchange Online. On Android, it is not possible to search the GAL from the Contacts app. There is one way to do it: install the Nine email application, which is an alternative to Outlook. It enables the integration even for Contacts app (besides allowing from the Nine app itself).


Pixel 3a XL repeatedly crashes and reboots when connecting to a specific Wi-Fi network

This is a known, supposedly fixed but not yet pushed into production issue for Wi-Fi networks utilizing 802.11k:
https://issuetracker.google.com/issues/144381412
See also:
https://www.reddit.com/r/Pixel3/comments/f7mych/reboot_when_connecting_to_wifi/
It has been more than a year and still unresolved in end user devices. I don't understand why it is taking this long especially considering:

That they have supposedly fixed it in the code.
How widespread this must be, as all devices are affected (even if most people may not realize it has to do with Wi-Fi, it took me a while to connect the dots). I am personally experiencing the same on a Pixel 3.

Please upvote and comment on the Google Bug tracker link above so Google can finally take care of this.


Convert to system app using Link2SD doesn't work on CM11

Just change the permission to be set on /system/app & /system/priv-app by the gapps updater. Following are steps for same:

Open gapps archive

Go into Meta-inf\com\google\android. Open updater-script with notepad.

Change the permission from 0*** to 0777 for /system/app & /system/priv-app
e.g. the line will be like set_perm_recursive(0, 0, 0755, 0644, "/system/app");
So change both 0755 & 0644 to 0777.

Save and update archive. Install from cwm-recovery.


Understand new icon in Android 11 call logs

Yes, this is voice calling over Wi-Fi but not related to Android 11.
I have a Pixel 4a, Android 11 with Wi-Fi calling enabled but do not see that symbol in call logs. I couldn't find any reference to it in the Android 11 changes.
Wi-Fi calling needs to enabled by a) carrier b) compatible devices. Both need to be compatible.  Probably your carrier, recently upgraded to this facility and hence you see this symbol. This symbol has been reported in call logs on certain devices four years ago on Galaxy S7 Edge. So, it looks to me like an OEM specific feature.

Faking your GPS location .. or Mock Locations.

Mock Locations can be enabled using the Development Options, this will acquire your location provided by triangulation of the connected cell towers and then apply an offset, I'm fairly sure.

If you use Network Location, your device could be calculating your location extremely inaccurately, by simply not reading the correct signal strength from a specific tower, maybe your body is on one side of the device and disrupting the signal to the Ariel.

Using High Accuracy GPS is not using the " internet " ( Network Signal Strength Calculations ) rather it's using calculations based on recognising visible satellites, then checking where on earth those satellites are visible from, it uses a separate internet connection to do these calculations, you'll see the network is active when your GPS Icon is flashing.

My phone is missing whatsapp communication

If your WhatsApp account is registered on a different device, while using your number, you can easily reclaim your account, as long as you can receive text messages on that phone number.

Download WhatsApp on your phone, register your account with your number, and it will automatically close the account on your friends phone.

On a side note, if you're looking to transfer all your messages from your friends phone to your phone, you can transfer the local backup from that phone, to yours.

Especially for recovering JPEG files, I would strongly propose to try the recovery software PhotoRec. It was originally developed to do exactly that, recover not files, but JPEG photos, on the disk - not even looking at the file system. As long as nothing got overwritten, it should recover a large part I expect.

I did not need it myself yet, but the way it works makes very much sense.

Runs on Linux, Windows, Mac, licensed under GPL v2+

PhotoRec comes in one package with the related software TestDisc - the package file named testdisk-* should contain both programms: TestDisk & PhotoRec Download

Note on recovering other files than photos:
PhotoRec should work well for many other file types, the programm PhotoRec was developed to be good at recovering photos, but was soon extended to work with other file formats with some kind of predictable structure too.

Interestingly, the open source license has a real practical relevance in this case: If the card is not removable, and you can not get an image from it to be used in a PC - you could, theoretically, compile/port it for your phone, to run it there in text mode per ssh connection from a PC.


Google Now not Speaking or Executing Comand

I am the author of the OP. Reflashing another Android version (currently using Lollipop 5.1.1) "solved" the issue.


As su, do this :

# mount -o remount,rw /system

You will now be able to delete it.

As said in comments, don't forget to

# mount -o remount,ro /system

or just reboot when you have finished. :)


The prompt for the password is probably caused by one of those apps. Try to remember the password you may have used for them.
 Or else please provide a list of the apps you've tried. (This can be achieved by going to the Google Play website and clicking on my apps.
As a last resort you can restore your phone to it's factory settings by entering the recovery.
To boot into the recovery press and hold power and volume up


Can anyone recommend a good email client?

I've been using the TouchDown client for the past month and have been very pleased with how will it works with our Exchange server. Not free, but worth a look imho.


On the HTC Desire X the memory (you would think you get 4Gb, but you don't) the partitions are as follows:

System is 940 MB,
Data is 1 GB,   (This is what you get for your apps really)
'Phone' storage is 1 Gb
1 GB towards "internal SD".

Basically you only get 1Gb on the device for your apps.
You could use a micro SD card to expand your storage and move your pictures/music/media to it, and some apps still support App2SD functionality.
Keep in mind Chrome can run up to 300 Mb no problem, so a cache cleaner may well help you with storage.  Lifehacker article on what to do if you run out of space.
You can't really mess with the other partitions without rooting and then partitioning your SD card with an EXT3/EXT4 partition and a ROM that supports Link2SD to 'trick' your phone into believing there is more internal memory. These partitions contain Android, HTC stuff, system apps, data partition etc. So you get 1GB in all (you have 138Mb left). Otherabove is the OS, HTC apps and other Android related things, that you have no access to (without a rooted device).


I solved this problem using DNAT redirection instead of port redirection, due to some limitations of REDIRECT involving broadcast traffic.

Can't see icon names on my android home screen?

Depending on the type of Home launcher, there are options to turn on/off icon labels. Check in Andorid Settings - Home, if not found, try long press on an empty part of the home screen, then check if you have options for Launcher settings (which are not the same as the Phone's settings). For Home Launchers like Go, L-Home, KK Launcher, and others, you can turn off/on labels for both your drawer and/or home screens.


This is a famous issue affecting USB file access over MTP.
I can't even remember how many hours I've lost trying to access files created by my first app on a PC (and I'm talking about GBs of important files).
If you start the app and it creates the folder, then you have to reboot the device in order to let your PC be able to correctly display the folder.
This happens only if you use USB and MTP.
You could solve the issue using MediaScannerConnection in your code or cleaning Media Storage's cache but I suggest you to do the simplest thing: use AirDroid ;)

Uhh, ok. If you're able to boot to TWRP, click mount and put a check mark in each box. Go back to TWRP file manager and poooof you shout see what you're looking for. Backup all partitions, then do a factory wipe.  Go to restore and only check "data". I suggest you root with Magisk (system-less) and find yourself a sweet custom ROM like AEX.


How to stop this type of service in Sony Xperia MT27i?

Those are due the debug settings enabled in Settings menu. Since I am not with any 4.0 device, I am unable to tell exactly what to be switched off.  Probably while switching on the USB debugging, you might have experimented with with other settings. Turn off all other than USB debugging to see these to go off.

Take a look at this similar question with similar answer.


Can I convert a system app to a user app, uninstall it, or move it to my SD card?

The easiest way to do this is probably to use Titanium Backup. If you long press on a system app in the list it will give you the option to "Convert to user app". Conversely, you can long press on a user app and "Convert to system app" as well. Note, though, that some system apps will not function well as user apps because their permissions may be restricted. Most of the apps you seem to be considering specifically will probably not have issues, I would imagine, though Google Talk actually might since it's somewhat tied into the Market (not sure).

Further, Titanium will allow you to directly uninstall a system app if you want to, without having to first convert it to a user app. All of the above requires that you have rooted your phone.


The only way to connect to the wifi with that device is with the wps button on your router. Go to advanced settings in the wifi menu, then press "wps push button"


How can I check which applications have been granted root access?

If you root your device using one of the more modern methods, then you should have a SuperUser.apk installed that will prompt you before any apps are given root access. The SuperUser application also keeps track of the applications that have been given root access.

If you don't know about rooting, there is no way you have an apps that uses root except if your phone is a second hand, and the previous owner did not wipe and reinstall a stock firmware.


How to fix wakelock issue on Samsung Galaxy S5 SM-G900H running Lollipop?

If you don't wanna root your phone there is no way of preventing the
power consuming apps from doing so.
From your screen shot I see the kernel and android system used most
of your power but they are not the ones using power but there is apps
on your phone are using core system functions so it's hard to say
witch app is really using to much power.
The other service using to much power is gpsd and I think it is the
real problem here. gpsd is a gps daemon it's a piece of software that
works with the gps sensor normally it shouldn't even appear in the
battrie stat ,but samsung repaced it by it's own software to offer a remote location service for the phone to help users find their lost handset through a website, just as Apple does with Find My iPhone. Unfortunately it appears to be causing the GPS Daemon to continually search and update your phone’s position, thus running down the battery.  While it’s a useful feature, you’ll need to deactivate it for now to save your battery and hope that Samsung issues a fix for it soon. Here’s how to do it: if you need this service even with the expense of power you can keep it but if you don't want it follow the next steps to disable it.

Open Settings
search for Security and tap on it.
Scroll down, tap Remote controls
Enter the password for your Samsung account, tap OK in top right
Slide the switch in the top right corner towards the left, where it
should change to grey or off.


Is there a way to know the actual permissions of an app now before installing?

You don't need an external tool for this. On the versions of the Play Store with the new "simplified" permissions dialog, you can still find a full list of permissions from the app's store page (the screen with the icon at the top, description, screenshots, &c.). Scroll down to the bottom of the page. Under "Additional Information" you'll see "Permissions" with a link "View details". Click this link to see a dialog with the list of individual permissions.

However, if you do want an external tool, AppBrain is an alternative web front-end to the Play Store, and lists the permissions individually for each app. From there you can click through to install the app from the real Play Store. Not all apps appear on AppBrain, but many of them do, especially the popular apps.

There's also a resource offered by Izzy, a good friend of this site. His website offers a curated list of apps, searchable by permissions. It also gives a fuller description of each permission, and highlights interesting combinations. Because apps are added to his site by a manual process, it's a very small list compared to the huge number of apps on the Play Store, but consists of a good range of recommended and popular apps in different categories.


If all you need is root access, try flashing the Siyah kernel via ODIN. Ensure you get the S2 version, as the dev has one for the S3 as well. Also, you will need the TAR version as you will flash it via ODIN (at least for the first time). Later instances, you can get the ZIP format and flash it via CWM (ClockworkMod recovery, which is built into the kernel). Apart from features like more processor steps, you can also overclock/underclock, adjust various parameters and have features like Backlight Notifications.

Since you will flash this kernel, you DO NOT need to flash the firmware. You can keep the stock firmware and your data intact. This kernel automatically installs root access so your primary requirement is also fulfilled.

As with all operations, ensure you have an off-site backup of all your data.

As an aside, once you install the kernel, get the ExTweaks app from the market which is designed especially for this kernel and offers a GUI/frontend to access many under-the-hood features.

Assuming you have all the drivers installed, here's how you go about it:

Download the TAR file of the Siyah kernel. Note that the latest series is for ICS, in case you're running Gingerbread, search for and download the appropriate older version of the kernel.
Start ODIN and connect your phone via the USB cable AFTER you enter DOWNLOAD MODE (Press Vol down + HOME + POWER button simultaneously for a few seconds after completely shutting down phone. At the warning screen hit Vol UP to confirm entry to download mode).
Once connected, you should see a COM port number with a yellow background.
In the ODIN program, press the PDA button and point to the TAR file.
make sure ONLY Auto-reboot is ticked and then click START.

If all goes well, you should see a green box with PASS! shown after which your phone will boot up. It may take a minute or two, so don't panic.

Refer to the FAQ and the respective threads on XDA-Forums for more info.


How do I troubleshoot the touch screen on an HTC Evo Shift?

Try Settings->Developer Options->Show touchscreen touches.  Unfortunately, HTC likes to move these settings around between versions so I don't know if it will work for you.

Replacing the digitizer is possible on many HTCs, I did it on my EVO 3D.  But that's probably what has failed.  Condensation will confuse it and make it stop functioning .


What are the consequences of installing CWM?

fastboot oem unlock always deletes userdata for security reasons, so it must be used only once (until you lock again manually).
CWM is needed if you want to flash a root package (you can't push it via fastboot), but that is not usually the only way to root a device.  The CWM install needs only the fastboot flash recovery recovery_name command, which does not affect user data.


Why do I need more than 200 megabytes of disk space to install an APK?

internal memory space is required to store app data and cache, it doesn't matter much if you move your apps to sdcard app data and cache still gonna be in internal memory.

if not willing then try some apps playstore which delete cache and auto move apps to sdcard

Can i flash indian rom in korean galaxy note?

No, do not try to do this, or you will brick your device. SHV-E160L and GT-N7000 have completely different processors (Qualcomm Snapdragon APQ8060 for SHV-E160L, and Samsung S5PC210 for GT-N7000); e.g., see this comparison.

There are some custom ROMs for SHV-E160L in the xda-developers section for AT&T Samsung Galaxy Note I717 (this device is closer to SHV-E160L, but also not 100% compatible, so look carefully and use only ROMs which are made for SHV-E160L).


Your software must have been corrupted, I suggest that you GOOGLE instructions on how to re-flash your firmware depending on your device, of course.

How to Block installing another app in android devices?

"i don't want any app to get installed on it..."

Technically this is impossible, since there are system apps like SystemUI and framework-res that Android needs to actually function.

But if you are talking about non-essential apps only, then perhaps you can delete them with root. Go to /system on a file manager that supports root, e.g. X-plore and Root Explorer, and delete the apps that you think are safe to delete. Be careful though, as those apps are on the /system partition and not /data for a reason. Your phone might become unstable after this.

The list of safe apps varies per manufacturer, but remember, Google is your friend!

Good luck.

Can i add money to a google play gift card and how

Answer is to your question is No, you cannot add an amount to a gift card after purchase. You'll have to purchase another gift card & redeem both in order to accumulate the desired amount.

As per the Comments

There is no information which actually states this. but this document says that user can use multiple gift cards to complete the purchase. What I've seen is, third party seller sells the gift card & updates the gift card number with the amount to google. so I don't think there is any provision to update amount later. otherwise they would have stated that way.
 https://play.google.com/intl/ALL_ALL/about/card-terms/


doing a simple search on the web you find that your tablet only works with voip. Sim card is only for data. You can not call or receive a call.


Cert file is used to unlock the network so that another sim card can be used with the phone or changing the IMEI number, country code... (all these are illegal in many countries).

The EFS is a special partition dedicated for your phone's info like radio signal info, imei, serial number and lots of files revolving around your SIM card and Wifi, Bluetooth (this includes your MAC address for all the radios of your phone).  Imagine the EFS as a big folder containing all of the important stuff that makes the "phone" part of your phone.

The MSL just allows you access to dangerous menus that could actually screw your device up if you set something wrong. So, in your case, Z3X needs to bypass MSL to be able to modify any setting, such as have write access to the EFS partition and change IMEI/unlock the network, etc.

There are thounds of videos out there on how to use that feature in Z3X Box.
You can find more help from here.


Why isn't there a Cyanogenmod stable ROM for my device?

Two devices with similar names, like the Sony Xperia Z and the Sony Xperia Z1, don't necessarily have the same kind of hardware. Sometimes there are even devices sold under one model name, such as the Samsung Galaxy SII, where the variants available in different countries have completely different systems-on-ship (SoCs) and other different hardware.

Devices with different hardware need different drivers &c. and a lot of system integration work that can't be shared between the two. Testing an unstable release to find the problems with it is very time-intensive, and of course can only be done on the exact hardware being targeted.

Since Cyanogenmod is made by enthusiast developers, rather than by people who are paid to do it, support depends on having an interested community of people with the system integration knowledge needed, and enough such people having that particular phone to run and test the ROM images.

It may be that there's not much more work required to support your device, but the people who might be able to do that don't happen to have one. Or it may be that none of the porters who have your device have enough free time right now to dedicate to testing and fixing ROMs. Lots of volunteer projects like this are stopped when members have children or start new jobs.

Even if you don't have the necessary knowledge, there are other ways you can help get your device supported. You might be able to help by contributing some money to support the developers, devices so that more enthusiasts can spend time working on it, or by testing and reporting bugs to make the process faster. If you ask the Cyanogenmod community how you can get involved and what would help, I'm sure they'd respond positively to that.


By what metric does Spotify decide whether a device is a phone or tablet?

Found this answer in a Spotify Community post:

Free account on a tablet only allowing shuffle play
Solution

Spotify classes a tablet as anything 7 inches or greater. Anything under this will only have shuffle play in a free account.

Spotify needs to identify each tablet using its ID in the build.prop of your tablet. If you are using a lesser known tablet it may be that it has not been matched in the database. Please contact support using the contact form here and let them know your device model, Android version and display size stating that you only have access to shuffle play.

Several general questions about Sony Ericsson Live View

From the Sony Ericsson website, the Live View specs page has no mention of a compass, gyroscope, accelerometer or similar. It doesn't mention anything about speakers either but does mention controlling phone calls and music playback on your phone, which would suggest its not designed to make noise itself but to control the music/sound on a phone (or other compatible device) that it's connected to.

The compatible phones page (other brands) lists a number of HTC phones, but not the Sensation. It does however say:

  Compatible with most other brands on Android 2.0 and up that are
  equipped with Bluetooth™ 2.1.

According to HTC's Specs page for the Sensation it has Bluetooth v3.0 compatibility, so it is likely that it will work with the Live View.


Can I, simultaneously, run two instances of the Facebook app?

You cannot run two instances of app with same package name because when you try to install it out of the box because the package installer checks if an instance of the package you are trying to install is already present and if present asks if you want to update the existing app.

You can however change the source code of an existing app to fool the system that it is some other app with a different package name  by cloning the source code and have a different package name. Reference link here

Also there's another way by making use of the special Facebook lite app.
 Facebook has provided a Lite app which is supposed to work for low-data-speed devices consuming less memory.
You can install one Facebook native app and another Facebook lite app and use multiple accounts. So you'll be able to get notifications from both the apps.

NOTE: This is possible because Facebook-app and Facebook-lite are two different apps (with two different package names com.facebook.katana and com.facebook.lite respectively)


What you want to achieve should be possible using adb backup (no root required):

Enable ADB USB mode on all devices (have to be done manually, AFAIK).
On the pre-configured device perform an adb backup of -all or if you know it only the relevant system settings app (I think it should be com.android.providers.settings?).
(optional) Decrypt and decompress the crated backup using Android Backup Extractor. You can now extract and edit the data in the backup, removing unnecessary/unwanted settings. Afterwards recreate the backup file using the modified data.
On each device perform an adb restore using the created backup from step 2 or 3.


Google Keep stopped sending push notifications on Android

I don't know whether this is a permanent and complete solution, and I don't know which one of the steps below are important or not, but -- I did the following steps, and now notifications seem to be working on my Android:

I went through and deleted all the notes that had reminders on them.
Opened Chrome settings -> advanced settings -> content settings -> notification settings -> manage exceptions.  Deleted exception for keep.google.com:443 from the list.
I had Keep opened as a tab in Chrome permanently, on a permanently running PC (windows).  I closed that tab.  If I need Keep on PC -- I'll need to open the page anew, do the edits, and close it again.  (The idea was that maybe the page being open did something to suppress notification somehow, or mark them "viewed" or something.)
Clear Keep application cache on Android. (Did not reinstall anything, did not delete all data -- just cache.)
Reboot Android.

It seems to be working for a few days now, haven't missed any notifications so far.


DND is not a cron job... It's "embedded" in the OS databases. Unless someone knows exactly what file and where, assuming it's ASCII editable file, a factory reset might be your only option.


How to avoid superbrick by flashing / modding / rooting?

1) Flashing the wrong recovery will not result in a hard brick.

2) Flashing a recovery to the wrong mount point might result in a hard brick, depending on which point you flash it to. If you flashed it to the bootloader mount point, well, then, the MB is toast.

3) If power is lost during flashing, it's probably still okay unless you were flashing the bootloader.

The things to avoid are:

A) fastboot erase bootloader <-- Why does this command even exist???

B) Flashing the wrong bootloader (most of the time the device will reject it if it's not made for it anyway)

C) Flashing the wrong radio

D) Doing stupid things with root


What is the Location of Saved Images from the Facebook App?

Images from the Facebook app are saved in $EXTERNAL_STORAGE/DCIM/Facebook/


I just did this!

/data/property/persist.sys.dalvik.vm.lib is a textfile containing one of two values: 'libart.so' or 'libdvm.so'. You can change from ART to Dalvik simply by editing this file.

Ex: adb shell 'echo libdvm.so >/data/property/persist.sys.dalvik.vm.lib'


i still can't connect gt-s5360 Samsung phone to windows 7 PC

Depending on the model of your phone, you may not be able to get the "Connect to PC" dialog. This is normal behavior.

Troubleshoot:

Since you can connect another phone to your PC, you probably have the
correct drivers (since Samsung uses a universal USB driver which you
can download here), but I would try to install it just in
case (it doesn't hurt to try).
Try disabling USB Debugging under Settings > Developer Settings.
Try enabling Settings > Wireless and Network > USB Settings > Ask on connection.


How can I stop the bootloader unlock process?

Your phone is basically waiting for input from you, not really doing anything under the hood, on the "Unlock Bootloader" screen. It should be safe to simply pull the battery and then reboot the phone normally (one corroborating source: Google's help forums).


Does the Pixel C Now Support HDMI-over-USB-C?

It doesn't; none of the Pixel devices support - it's a Google  Store goof up

I was helping a friend on the purchase decision of Pixel XL and lack of USB C - HDMI was a major drawback. Just to confirm we contacted Google support and they confirmed it doesn't support HDMI
Seeing your question, I contacted them again, since there are plenty of references to lack of support and only Google Store confirming it supports, which is an oddity. They verbally confirmed that it is a  Store site issue and followed up on mail, confirming that they are working on fixing the error. Screenshot below

You may also wish to confirm by calling them up from the contact us on the store web site


How do I know if it's safe to opt out of the Android Beta program without wiping my data?

You aren't running a Public Release, or ?  In the first sentence you said you opted in to the Beta and are running "the latest public release"...You would first need to determine what Build you are running by going into Settings - About phone - under Build Number.

From the Android Beta site you linked in your post, under "How do I verify that I'm running a beta version of Android?":

1.  Navigate to Settings > About > Build number. If the build number starts with NP, you are running a beta version of Android N.

2.  Reboot your device. You will see a message informing you that your device is running a beta version of Android.

I would assume that if you are running a current Public Release that you would not have to worry about data loss, but as always, backup any files/docs/photos/music you would like to keep in case that happens before opting out of the Beta Program.

The lastest Public Release for Android 7.0 is NRD90S, and Android 6.0.1 is MTC20K according to what Google has posted here:  Google Nexus Factory Images


Will Dropbox delete files from my online storage?

If you delete a file from your mobile device, the file remains on your Online storage.

To have the file permanently deleted, you need to delete it from your online Dropbox account, accessing it via their website.

I've just run this exercise (to prove the theory):

Take photos;
Sync Dropbox;
Delete photos from my device;
Access laptop;
Photos were downloaded;
Access Dropbox website and login to your personal account;
Delete photos;
Photos were automatically removed from Laptop and a notification was presented asking if I wanted to undo the operation.


Xposed framework greyed out. Should I be concerned?

I used Xposed some time ago and as far I can remember those buttons are grayed out because on marshmallow (possibly lollipop) you must flash framework files via .zip file. Maybe I'm wrong and forgot something.
Are you sure it happened recently, that it wasn't there all the time?
However I don't think you should be concerned because Xposed and it's modules work fine (right?).
It says "Xposed framework 85 is active"


Delete file with special characters from un-rooted device

I converted the file into a 240p MP4, downloaded it using Chrome, and I was able to delete the file using Solid Explorer easily.

I was also able to  delete it using Termux. I installed it, enabled Storage permission for it from Settings app, launched it, and used these commands:

cd /sdcard/Download/   #I had downloaded it in Download folder.
rm FILE_NAME           # to type file name, I didn't actually type it. I used Hacker's Keyboard which comes with Tab key for auto-completion. I typed JER and pressed tab key to automatically load the full file name including emoji (which actually renders as a flame in Termux).

If you wish to keep your default keyboard, Termux provides two more means to use Tab autocompletion. Either use Volume Up + T to send a Tab to the shell, or use Volume Up + Q to display an additional button row on top of your keyboard, which contains frequently used commands such as Esc, Ctrl, Alt and Tab itself.


What is the difference between unmanaged vs managed in-app product?

The short answer is that managed items are items that can only be purchased once per user and that Google Play keeps track of their purchase, unmanaged items aren't tracked by Google Play and they can be purchased multiple times.
A fuller description is given in Google's In-app Billing Version 2:

Managed per user account — Items that can be purchased only once per
user account on Google Play. When a user purchases an item that uses
the "managed per user account" product type, Google Play permanently
stores the transaction information for each item on a per-user basis.
This enables you to later query Google Play to restore the state of
the items a specific user has purchased. If a user attempts to
purchase a managed item that has already been purchased, Google Play
prevents the user from purchasing the item again and displays an "Item
already purchased" error.
The "managed" product type is useful if you are selling items such as
game levels or application features. These items are not transient and
usually need to be restored whenever a user reinstalls your
application, wipes the data on their device, or installs your
application on a new device.
Unmanaged — Items that do not have their transaction information
stored on Google Play. This means that you cannot later query Google
Play to retrieve transaction information for those items. For
"unmanaged" purchases, you are responsible for managing the
transaction information. Also, Google Play does not attempt to prevent
the user from purchasing an item multiple times if it uses the
"unmanaged" product type. It's up to you to control how many times an
unmanaged item can be purchased.
The "unmanaged" product type is
useful if you are selling consumable items, such as fuel or magic
spells. These items are consumed within your application and are
usually purchased multiple times.

Note that only version 2 of the in-app billing deals with both managed and unmanaged, version 3 only deals with the managed in-app product type.


Samsung Galaxy GT-S5300B dead / bricked (?)

It doesn't look good I'm afraid.  You would need to be able to see 'something' relating to the phone from a 'lsusb' command to be able to use odin to recover your device without cracking it open.

You've probably already seen this, but it looks like the JTagBox is your best bet.

Good luck!


According to this XDA post Bluetooth USB dongle support is native starting from Android 4.2.2. So if you're running 4.0 as the tag suggests, it doesn't work. You'll have to update the tablet.

Also, you'll have to confirm that the USB port supports full host mode with USB Host Diagnostics.


this issue is caused because the "terminal emulator" app does not handle scp transfer (as far as im aware) upgrade to "better terminal emulator pro" app and the issue disappears.


Bypass "Swipe up to unlock" on Android Lollipop lock screen

As far as I know, currently there is no setting to turn off the "safety lock" due to the addition of notifications on the lock screen. (Strangely, the lock is still there even if the user chooses not to display any notification)

The best bet to bypass this is to use Smart Lock's Trusted face, a new feature in Android 5.0 Lollipop similar to previous face unlock. You can bypass both "safety lock" and "pattern lock" simultaneously by looking at the phone while on the lock screen. I would say there is no downside (as far as my experience goes). If it fails to detect your face, then you just have to swipe up and draw the pattern normally.

How to set up:

Go to Settings - Security
Tap "Smart Lock", confirm your current pattern lock
Tap "Trusted face" and follow the instruction


How to fix "Encryption unsuccessful" and bootloop issue on Andriod 8.1?

This happened due to the infamous BLOD due to premature hardware failure of Qualcomm Snapdragon 810 chip set. All Qualcomm Snapdragon 810 chipset will have the same fate after around 1.5 years of usage. Can't believe Qualcomm messed up this bad.

The instructions in the below linked worked perfectly.
https://forum.xda-developers.com/nexus-6p/general/bootloop-death-blod-workaround-zip-t3819515

The phone is surprisingly pretty usable for daily tasks even after disabling the A57 cores.


How to Edit Track in Google "My Tracks"?

Upload the map to Google from your device
On maps.google.com, click "My maps" (top left, below the Google Maps logo)
Select the map you want to edit
Click the 'edit' button (top right in the left sidebar)
The line is now editable. Right-click points on the line you want to delete and select 'Delete this point'.


How can I take on-device screenshots of "secure" apps?

As your device is rooted, you could use the Xposed module DisableFlagSecure:

  An Xposed Framework module that disables FLAG_SECURE on windows system-wide. This lets you take screenshots and do screen capture in apps that normally won't let you. (That said, you probably don't want to leave this on permanently).

You can of course also find it in the Xposed Repo.


To root your device you first need to unlock your bootloader, and Huawei no longer provides bootloader unlock codes. There are several possible options, but all of them are paid, ranging from €3 to $55 depending on your choice.
I'm not affiliated with or responsible for any of the services mentioned below.

Read unlock code from phone:
(Keep in mind that these methods are not guaranteed to work in Android 8.0.0 or newer, but if it doesn't work you can ask for a refund)

DC-Unlocker €3: You can buy 3 credits (one credit=one euro) from their website https://www.dc-unlocker.com, download the software for your PC and get the unlock code by connecting your phone to your PC. You can follow the tutorial in their website for a complete step-by-step.
HCU-Client €3: This is associated with DC-Unlocker but supports some newer devices, so it is generally recommended over DC-Unlocker. The website is https://hcu-client.com and you can follow the same steps above.

Order unlock code by IMEI:
(This method works for any version, but is more expensive)

Global Unlocking Solutions $20-$22: The website is https://global-unlocking-solutions.miiduu.com/bootloader-unlock-codes-choose-model-below .The website looks sketchy but plenty of XDA users have had success with them. The ordering process is straightforward.
FunkyHuawei $55: The website is https://www.unlockhuawei.com .The advantages of FunkyHuawei are: If it doesn't work you can ask for a refund, and they just have a very reliable track record.

You can just Google how to install ADB and Fastboot. There are plenty of guides. Also install Hisuite (for drivers) too.
After you order the code unlock the bootloader with fastboot oem unlock ******** (replace with the code, also that will WIPE ALL YOUR DATA)

Download TWRP from https://forum.xda-developers.com/9-lite/how-to/honor-9-lite-twrp-3-2-1-0-available-t3771358, rename it to twrp.img and to flash it use "fastboot flash recovery_ramdisk twrp.img".

Google "magisk xda download" and download the Magisk ZIP from the XDA thread. Boot into TWRP (You can Google how to do that in Huawei devices) and go to Install, and choose the ZIP you downloaded, and confirm, and you have rooted your Honor 9 Lite.

So that is there to it. A lot of work and some money is needed, but there are no other choice for now.


Two popular apps are TubeMate (as zamin suggested) and VidMate. They can download videos from all popular video hosting websites. You won't find them in Play Store due to some copyright issues. Sites like YouTube, DailyMotion, Youku etc are provided as speed dials so you have to manually enter dnatube.com  in address bar. Comment if not working.


Light of Back button is not working on my Android mobile

Do a factory reset of your device (Remember to take app and data backup before doing the reset).

If this doesn't solve the issue, it may be hardware issue (either LED gone bad or any physical damage happened).


Is it possible to disable 2g connections completely, while allowing 3/4g connections to continue?

Izzy's comment to the original question is actually correct.

On your phone's dialler, dial *#*#4636#*#* and open the Phone information menu.
In the Set preferred network type setting, you can now select the combination of network types that suits you most.

Unfortunately the list of network types uses fairly confusing abbreviations, I'll try to shed at least some light on it:

2G: GSM
3G: CDMA, EvDo, TD-SCDMA, UMTS, WCDMA (competing standards used in different countries)
4G: LTE

I don't have the first idea what 'Global' and 'unknown' do.

Some entries have additional remarks:

only: use only this particular standard (d'uh )
auto (PRL): when your provider's network is unavailable, use the 'Preferred Roaming List' to determine roaming networks preferred by your provider (e.g. that your provider has partnered with)
preferred: probably means that other network types are not used unless the preferred are unavailable. This may differ from default behaviour because by default, a 2G network may be used even if a (weaker) 3G or 4G network is available.

Remember the original value, in case you pick one that doesn't work for you.

To downprioritize 2G, you might want to try LTE/CDMA/UMTS auto (PRL): It covers 4G and most 3G standards, falls back to 2G if nothing else is available, and uses a PRL for roaming.

If you're still frequently stuck in 2G mode because you're moving around in an area where 3G/4G is available, but sketchy (for example if you frequently pass through staircases that block all but 2G), you can completely disable 2G by selecting something like LTE/TD-SCDMA/UMTS and see if that works for you (depending on which network types are used in your country).

Can I open a second Gmail account in a separate app?

Unfortunately the answer is that it will depend...

It will depend how your work email is setup and/or the device being used.

Option1 - Android Enterprise
If your organization has an MDM (mobile device management) and they support a configuration called Android Enterprise it is possible they can distribute another instant if Gmail that keeps your work and personal email separate.  You will need to contact your companies help desk for more info.  Note your device must be new enough to support Android Enterprise.

Option2 - Samsung Devices
Some newer Samsung devices allow you to do this with a feature called Secure folder.  Secure folder allows you to add applications like gmail to the secure folder.  This allows you to run another instance of gmail or most other android.

Hope that helps


How can I keep apps from moving off the home screen?

A work-around you could use on Android to refrain from having apps move or be uninstalled by either accident or someone trying to purposely do so:

Settings -> Accessibility -> Dexterity and Interaction -> Press and hold delay -> Custom

From here, you can just set an obnoxiously long press and hold delay so that when icons are held down to be either moved or uninstalled, it takes however long you've set the interval for to actually initiate that command. So, a) doing it by accident becomes harder and b) Someone who doesn't know you've set that feature will assume it doesn't work and not opt to wait 35 seconds of holding an icon down.

Just my little trick, at least.


Nexus 6P - cannot turn off Developer Options

I suspect this strange behaviour is caused by some setting that requires developer options to be enabled, but itself is not deactivated for instance USB debugging., transitions/animations etc.. (this has been observed to enable developer options in some LG builds typically when the battery saving feature disables animations at 15% )

As a workaround try this:

Go to developer options, turn off debugging,
Then disable the  developer options with the switch on top of the screen
(same as your screenshot)

The trick is to first deactivate setting that uses developer options then toggle it off


Fix permission option removed from CWM recovery 6.0.3.6

It was removed because

  It's total placebo these days. I wrote it for dealing with the silly things that happen when we used to put apps on SD before Android supported it. Since then, it's been something of a sugar pill that magically fixes all problems without actually doing anything.

App with colorful 'C' icon on blue background and a Chinese name -- what is it?

Okay, so I traced it back to mygyapp.com

But  your screenshot shows the name:

Well, based on my little search, the app in the screenshot is part of that site. That app or its mother, the site, seems to be some sort of app market. That's my educated guess. I searched the string 应用酷 on that site and came up with this app -- which is what you've in your screenshot:

The translation differs. One translation names it "Application of cool" and the other, "Applications cool". The product page shows:

How did I find all the info?

Fortunately, you provided a screenshot with good resolution so I separately cropped app's icon and name.
I extracted the name from the image using a website featuring online OCR.
I used the raw name into Google/Baidu search and there we go!

Of course, I did too many mistakes here and there.


No, MTP doesn't work like that. MTP is a client-server file transfer protocol, a bit like FTP. Your best bet is to either find another protocol the car supports (there are many network audio protocols, so it's likely it'll support one), or failing that, fix whatever is making the aux input sound bad (most likely a bad cable or connector, or the car is expecting line-level instead of headphone-level audio).

How Can I Ressurect My Chat History from Google Talk on Droid?

Google chat/Talk sessions can be recorded and saved to your Gmail account using a Gmail setting. From Google's Chat Support pages:

  Changing your chat history settings

  You can adjust your chat history
  settings in Gmail at any time. Chat history for Google Talk is only
  available to users who are signed in with a Gmail username.

  From Gmail:

  Sign in to Gmail.
  Click the gear icon  at the top of any Gmail page, and open the Chat tab.
  From the Chat tab:

  Select 'Don't save chat
  history in my Gmail account' to disable chat history saving, or,
  Select 'Save chat history in my Gmail account' to enable chat history
  saving.

  Click Save Changes.

  Keep in mind that if you've disabled chat
  history saving, people you chat with may still choose to save chat
  histories in their Gmail settings. If you would prefer that someone
  you're talking to doesn't save your chat, you can take the
  conversation off the record. If you're talking to someone who is
  connected to the network with a desktop chat client, it's possible
  that his or her software is keeping a separate copy of the chat
  history.


Apps' update status in Market app not always reliable?

I have noticed that I sometimes get a notification that an update is available, but when I go in there, I am unable to update. I, at first, thought that it was some type of syncing issue like you describe, but I have realized ( at least in my situation ) that I have the apps set to update automatically. So I get the notification, but the market actually has already updated the application in the background.

Based on your comments, and if you eventually go in to the market and there is actually an update available for an app that you previously were notified about, then I would say it has to do with how google rolls out the updates. As Chahk discussed, the notifications seem to go before the apps, in some cases. Google does this with just about everything they roll out. Updated in batches.


Disable low-battery warning, specifically on XOOM

No, there will not be an app that changes it since it is in the system. You have to have root to change system settings.  Once you root, there may be a developer who has a file you can flash that will do it for you. I am sure that if you thought it was annoying, so has a developer. It's only slightly easier than changing it yourself.


What is the meaning of an "eye" system icon on Samsung devices?

AFAIK, it is the Samsung feature which keeps the display turned on for as long as you're looking at it. This is helpful if you're reading something off the display and don't want it to sleep.

The setting/feature can be disabled in Display Settings of the phone.


If there is a computer next to their icon, it means they are on a PC (or Chromebook).

If there is a phone, they are on their phone. The position of their icon shows the last message they read.

If the icon is dim, it means they are not looking at your message. Doesn't mean that hangouts is open, or closed.


SDcard in lollipop still readonly using EZPDF

Although the new Lollipop update allows apps to write to SD Card, it requires the user to grant the apps access, like you've stated above.

For apps to gain access they have to call the new API introduce in the   lollipop which allows user to grant app permissions.For the apps to call this API, the devloper of the apps have to write code into their app to do this.

As I was saying above, the devloper needs to write some code to do this, for which the particular app you want to grant the access SD Card does not have.

I am sure that their are ways to forceable do this, of which I don't know of, that would probably require root, phone modification and technical know how to do.


Power Efficiency: Network mode 4G LTE vs 3G GSM/WCDMA?

This is a big one which is tough to give a complete definitive answer.

There are a ton of variables involved that could easily change the the end data as per you. A few of things are involved are conditions like theory, optimal, or real world environment:

The carrier and their network, the technology they utilize.
The data type itself and whose definition of what is really needs to be met to be considered truly that type.

To give you an idea in your question about refresh rate, first, whose definition of efficiency should you go by meaning? Is it solely based on an acceptable signal strength? Like, one data type refreshes at an exact unit of time because there's just maybe a chance of a better signal even if it's already at a super strong level, then add the tower hand-offs, oh my. Wow that grew fast.

Check out this excerpt from a book reference by O'Reilly which includes references to reports and papers to go deeper if wanted.


Is it possible to connect Nexus 4 to Windows Server 2012 R2?

Actually Windows Experience Feature is the answer!

I had the same problem and could not install usb drivers for a MotoG on a win2012 Server, but when I installed Desktop Experience feature, all runs flawlessly, drivers auto-installed and all!

BUT it is a little weird to find it...

Go to:
