My Moto 4G is caching everything. Is it a normal behavior?

This is normal behavior, my brother has a moto e (same amount of ram), and it ends up unloading lots of recent apps, if this was a priority you maybe should have gone with a different phone (the moto g has a good processor, so can run plants vs zombies, but it can't multitask as well.


Repair SD card removed from phone without unmounting?

tesdisk can probably also fix this (it detects the partition also) but I ended up using DiskGenius to fix the partition table and save it, all data come up and it's working 100%. Easeus Partition Magic wasn't able to recover the partition in case anyone gets into the same trouble.
On DiskGenius:

First insert your SD card into your PC and run DiskGenius;
Click on Partition Recovery, Whole Disk and start the scan, it can take a few minutes to run;
While scanning, select Reserve for all partitions that appear;
Hopefully DiskGenius can find your missing partition that will appear in Green on the left Tree menu under your SD card;
If you are happy with the partitions found, just hit Save All and changes will be saved to the SD card

I was able to follow these steps and recover 100% functionality of the SD Card without formatting or losing any data. Be aware that DiskGenius is a paid app. I can guess the free testdisk can also achieve this but I was afraid to do it with the more 'manual' steps required by testdisk.

Samsung Galaxy "SHORTCUTS" for the lock screen not available in S3 Ver. 3.4

You need to enable lockscreen widgets, to allow the shortcuts to be shown.

Go to Settings > My device > Lock Screen and tick the box "Multiple widgets"

The actual layout can change from device to device slightly, but below will give you a rough guide to how to find them.

Now click on "Lock screen widgets and turn on the button "Favourite apps or camera" on.
Now click on the actual option (by this I mean click the text, not the button) "Favourite apps or camera and select "Favourite apps" and hit save.

How can I prevent Android from auto-installing all of my apps?

Make sure to disable the auto-restore under Menu -> Settings -> Privacy -> Automatic restore before installing a different ROM.


Set up new device with very long Google password

#2 that you tried is if you have 2-step authentication on. The App Passwords are for applications (like some windows apps, for example, that authenticate to google) do not work with 2-step verification. These passwords are meant to be used with those apps. App Passwords will only work if you have 2-step authentication enabled on your Google account.

I would suggest that you change your password to something that you can actually remember, and type in less than 15 minutes, then enable 2-step authentication.

2-step requires you to use an app like Google Authenticator (or SMS)

This app will provide an access token that is only valid for your account, and for like 60 seconds. It is similar to SecurID.

Notice that Google Authenticator will provide me tokens for use with multiple google accounts, and other services as well, and the tokens are different for all of them. The Pie is a countdown, and once it reaches 0, that token is no longer valid and a new token will be displayed.


After rooting- apps on SD card seemingly non-existant

Removing the sd card and SIM, then rooting can do this. It's better to leave them in

This is probably down to the fact that a root upgrade (I.e. Rooting) can change the apps links, meaning a reinstall. I done the same as you, and had to redownload terraria when it was not there but was, and I kept my data. It's kinda like you delete the app, but not the data.


Do I have to install a custom ROM if I root?

You don't have to install a custom ROM, you can use a stock one. There's usually rooted versions of stock ROMs readily available for most devices, with the only difference between them and a completely stock ROM being the addition of Superuser and the su binary (and often busybox). If your device is supported by a simple software rooting method (HTC stuff often is) then you can simply root and be done.

ClockworkMod is not a custom ROM, it is a custom recovery image. The recovery system is basically a minimal environment and GUI that exists on a separate partition and can be used to backup or restore your device's state, install new ROMs, and perform some other functions that can help you fix your system if it gets into a bad state. The differences between these and other things is covered pretty well in What is the difference between: Rooting, Jailbreak, ROM, Mod, etc.? and What is ClockworkMod Recovery and what is it for?


Backup an app's complete data when phone is stuck in bootloop

You would need a custom recovery for this solution and it appears that you already have TWRP installed.

Setup adb in PC, if not already. Boot into recovery mode. Mount data partition. Find the package name of your app, if don't know already and execute these commands:

adb shell
busybox tar -C / -cvzhf /sdcard/PACKAGE_NAME.tgz data/app/PACKAGE_NAME* data/data/PACKAGE_NAME  # replace PACKAGE_NAME with package name of the app

The last command will create a tarball with extension .tgz under /sdcard with name as package name of the app. The tarball would contain the app's APK (among other things) and app's private data. Files' ownership and attributes would be preserved automatically. Extended attributes (such as SELinux context) won't be preserved in this command.1

Your app may be having publicly accessible data under /sdcard/Android. You can simply use adb pull or MTP to copy those files into PC and restore them using adb push or MTP, when needed.

To restore the backup, do:

adb shell
busybox tar -C / -xvzhf BACKUP_PATH   # replace BACKUP_PATH with the file path of your backup, such as /sdcard/PACKAGE_NAME.tgz
restorecon -FRv /data/data/PACKAGE_NAME  # this will set default SELinux context on the data files of your app

Unmount data partition, reboot and you should be able to find your app in restored state.

Note:  I've tested this solution on an unofficial CM13 build.

1 I noticed that bionic build of busybox (found in TWRP v2.8.6.0) among other arguments has -p for tar which is used to store SELinux contexts. If the file was created using that argument, then during extraction those contexts would be restored automatically, hence, no need to run restorecon explicitly.


after hours of searchng I found a post where a suggestion was just to hold the scanner on the qr code... It worked..

So nothing to do here ;)


The requirement being that you must be ROOTED, you could get Titanium Backup and back up your phone using that.

The reason for using Titanium Backup is so that you can selectively restore parts of your data if you were to install a different version and/or build of Android. NANDROID backup is good for having a safe image to fall back on but it isn't good for restoring data on top of a new OS installation (there are side effects sometimes).


How do I configure Android without using the touch screen?

You can send fake keys and touches to an Android device using adb and USB connection.

http://philatwarrimoo.blogspot.com.au/2013/06/root-huawei-x3-8150-without-windows-or.html

About 3/4 into my post I present a bash script to send keys and touches to allow me to setup an Huawei IDEOS phone.

eg

adb_tap 0x70 0x80  # tap on android icon
adb shell input keyevent 20  # down to 'Create'
adb shell input keyevent 20  # down to 'Sign in'
adb shell input keyevent 23  # enter
adb shell input text 'username@gmail.com'
adb shell input keyevent 20  # down to 'password'
adb shell input text 'password or 2-factor code'  # 2-factor pw
adb shell input keyevent 23  # enter
adb shell input keyevent 20  # down to 'Sign in'
adb shell input keyevent 23  # enter


You may need to enable USB Debugging enabled

To enable follow these steps:

Open settings
Open Info
Find the Build Number and tap on it alot until it says You are now a developer!
Exit Info
Open Developer options
Tap on USB debugging
Tap on OK

Notes:

In 4.1.x and before skip steps 2-4
In 2.2.x and before goto Settings->Applications->Development->USB debugging


Help deleting someone else's Google account from my phone

Go to Settings > Account > Google then select the account to be removed.

No, deleting an account from a device only remove it in that device.


Manual Update: Exclude a certain apps from notifications

There's no real solution -- but depending on how much this annoys you, a work-around is available:

install AppBrain App Market. You can think of this app as an "alternate frontend" to the Google Playstore (and yes, it is no stand-alone market, as all updates/installs are re-routed to the Playstore-App).
log-in to the Appbrain Website with your browser and your Google-Account to initialize your account with Appbrain
now login with the Appbrain App you installed, and synchronize your installed apps.
Appbrain now shows you available updates to your apps. You can run them in a batch, or one by one, or can decide one by one whether you want to skip just this update, or skip this (and all future) updates to this app -- so it will not annoy you with updates you are not interested in.
start the Playstore App again, go to your apps list, open the settings, disable all update checks, updates, etc., and close it again.

Now the original Playstore won't ever notify you about any update whatsoever. Instead, you use the Appbrain App for updates. When looking for some new app, you can chose to use either of them. You might also decide to install the AppBrain Ad Detector along, and then probably will use the Appbrain App only -- as it helps you avoiding apps with excessive ads.


As long as your tablet is running Android 4.1 or newer then there are a number of music players that can put player controls in the Notification area on your device. This is so that you can just access the notification bar while you're running another app, without exiting the original app.

I haven't got a screenshot handy of how it looks on a tablet, but here's an example of one on a phone:

Try searching the Play Store for something like MP3 Notification Bar Controls


I don't know if you can change that but you can always install the same Keyboard that you had in Nexus S. Search market for Gingerbread keyboard and/or Ice cream sandwich keyboard.

Those keyboard are the keyboard that ships with Android. Samsung like HTC modifies/creates keyboard that differs from stock keyboard. Samsung keyboard is very much similar to ios. But unlike iPhone style, you can always change keyboard in Android OS.


How to edit custom spelling dictionaries?

User Dictionary Manager might be what you are looking for.

From the description:

  UDM is an application that allows you to
  edit/export/import/delete/clean the user dictionary words found on
  your Android phone.


How to change storage location in micromax Elanza A121?

You could move installed applications to SD card or could install a rom with app2sd or data2sd.

But by default they'll stay on your phones internal memory.
Try this apk I'm using it, and I can say I'm pleased with it.

EDIT 2#

If your specific request is to change default location of captured images then you can use this application.


Ringing volume is reduced after after updating Moto G2 to Android Lollipop

I suggest you to perform clear cache on your device. This steps will remove any temporary files that may be causing the problem, but will not delete your files or settings.

With the phone powered off, press and hold the Volume Down + Power button at the same time and release after two sec.
Press the Volume Down button twice to highlight "Recovery mode"
Press the Volume Up button to restart into Recovery mode.
You'll see an image of an Android robot with a red exclamation mark and the words "No command."
Hold the Power button, do not release it, press the Volume up button and release it (hold on the Power + Volume Up button and release).
Use the volume buttons to scroll to "Wipe cache partition" and press the Power button to select it.
"Reboot system now" will be highlighted, press the Power button to select it.


Android wireless debugging on multiple devices

adb tcpip <port> doesn't restart the adb daemon in your PC but in  Android and binds it to listen to that specific  port. You can always connect multiple devices in wireless mode.

Follow these steps:

Plug first device and restart adbd in tcpip mode using adb tcpip <port>.
Connect to first device using adb connect <host>:<port>.
Unplug first device, plug second device and restart adbd in tcpip mode using adb -s <serial> tcpip <port>.
Connect to second device using adb connect <host>:<port>.

You may now unplug the second device. If you execute adb devices you would see both the devices connected in wireless mode. Whenever you intend to do any operation on any of the device, supply identifier using -s.

Example:


Chrome redirects to messenger on Samsung mobile

Try any of these steps:
×-Clear Cache, Cookies and Data of Chrome.
×-Also Clear the downloaded data if there's any infected file.
×-Check any previously installed apps causing troubles, if any, try uninstalling.
×-Scan using any good antivirus app or built-in one.


Instead of symbolic link, you may use DropSync (Pro) which allows you to define the Dropbox (cloud) directory and also the file (local) directory in your device.


App updates automatically even after uninstall?

This seems to be a bug. Try this:

Open Play Store.
Navigate to My Apps, then go to the All section.
Delete the app from your account (usually by a small X in the top right corner of the list entry).

See diagram below:

If it does not give you the X to delete the app from your account, click on the app in that list and uninstall it from the app's Play Store screen.


Is it possible to designate an alternative wifi connection test site?

Yes. Since Android 7.1 the method is a little different (not gonna mention the old method here) - fire up adb shell then use the command settings put global captive_portal_https_url **site domain here**.

In the past g.cn (Google's remaining Chinese domain) worked alright, but since Nougat for better reliability I'm using one hosted by V2EX: captive.v2ex.co/generate_204, so the full command becomes settings put global captive_portal_https_url https://captive.v2ex.co/generate_204.


Real root can not change any thing on /system original files!

Based on my comment and Yasser's subsequent comment , I can conclude that the issue was the immutable attribute set on the file build.prop. If other files and directories also can't be edited or deleted, then they may also be having the same attribute or append-only attribute.

The remedy is to use this command with root privilege:

chattr -i FILE_PATH    # FILE_PATH is the file which currently has immutable attribute

Use -iR followed by a directory's path to remove immutable attribute from a directory recursively.

It is to be noted that OP already has busybox installed. chattr and lsattr aren't the utilities found natively in Android.

Relevant info about the used chattr command and append-only attribute can be found in my answer here.


4 viruses on my phone?? Is this message legit?

It is phishing site, I've just had the same on my Samsung S7,

Gallery application replacement for adding text based Photo Notes

There are a number of photo apps that will let you edit exif data on the android.  This one specifically does the data: https://play.google.com/store/apps/details?id=com.teapps.exiftageditor, some do other pieces of editing, some sort your files for you, etc, etc.  Take a look around for one that works well with your particular image work flow.

Wikipedia has a nice roundup for PC/desktop meta data editors here: http://en.wikipedia.org/wiki/Comparison_of_metadata_editors. Your choice will of course depend on your PC, budget, and needs.


The only duplex modes of LTE are TDD and FDD (see band list on Wikipedia) - in other words, non-TD-LTE bands are FDD-LTE.

How to change my default storage location for play store on samsung J1?

In Android ... Go to settings, Apps and press menu to select options, I think it's even called default storage location !...   Some devices dont have the option ... You need a app like Apps2Sd


Paid app accidentally deleted and now can't re-download: says I "already own" the app

Well, I figured it out ...

Go to https://play.google.com/apps
Log in with the same credentials that are used on my device
A list of all my installed apps is shown. Find the deleted app and click on its icon
An "Installed" button shows up. Click on that button
A window pops up with an "Install" and "Cancel" button. Click on the "Install" button.

This caused my device to start downloading and installing the app. Now it has been successfully re-installed.

Problem solved!

PS: It would be nice if Google allowed us to perform this same function from the Play Store app on our devices, so we don't have to go to a browser and access https://play.google.com/apps.


You could try to find an ftp server app that supports rooted devices to access system folders. If you don't have to use ftp, you could use airdroid, which also has a remote file manager.

Another option (if your device is rooted) would be to symlink the folder so that it's stored on /sdcard, which you can easily access


Error 504 when downloading apps from Play Store?

According to the list of status codes at Wikipedia, a 504 error means the following:

  504 Gateway Timeout
  The server was acting as a gateway or proxy and did not receive a timely response from the upstream server.

In other words: the culprit should neither be (on) your device, nor (at) Google Play -- but in between.

A thread on the Nook forum describes the very same problem, and one of the conclusions there is:

  Generally, that means a Gateway error and I would suspect the problem being on the router end rather than the Nook side. Sometimes a router reset will cure it.

Which corresponds to my conclusion. So if you're using mobile data, it might help to switch data off and on again (or better: switch to airplane mode and back), in the hope you will get a connection into a different segment of your provider's network (and thus a different gateway on that end).

From a thread on XDA about all the Google Play Error Codes

  Method 1:

  clear data
  clear cache of google play store & google service framework

  Method 2:

  remove your gmail account
  reboot
  Re-add account

Funnily, the very same issue comes to a very different conclusion on Yahoo answers: here the user had not enough space on his device, so after removing some other app it suddenly worked. I suspect this was a co-incidence (when he tried again after having freed up space, the gateway was "fixed") -- but it cannot hurt to check for that.

Several more sulutions might pop up with the time. To me it proved helpful to search Google for '"Google Play" "error 504"'.


Using headphone out to hook an alarm clock app to speakers

I just tried with my Archos 70 and alarm clock plus v2 and it didn't seem to work at first but when I played with the headphone-jack and pulled it out about half a millimeter and it worked.  This would seem to be a problem with the jack, but it works just fine when playing videos or music.  I think the issue might be that the alarm clock apps are sending the audio out on just one channel and it's not getting picked up for some reason by the stereo speakers.  I remember I used to have a similar problem with my old walkman and certain headphones and I'd have to pull the jack out just a little bit.  I know theory doesn't make complete sense because it still should work just out of one speaker but it's something I've noticed about 3.5" headphone jacks for years and can't explain it.

Also, if you don't want to mess around with playing with the depth of the jack or trying a mono speaker, you could set the Alarm Clock Plus to launch Pandora which would probably play just fine over the stereo speakers.


reinstall barnes and noble software on a rooted nook color?

This is the firmware for your device's original software (v. 1.0.1).

Simply download and save to the micro SD card and use it to flash your Nook.

Voila! Job well done. The XDA page Chahk posted is an excellent resource and reassuring, stating that it

  Keep in mind that the Nook is really hard to brick. By that, I mean almost impossible.

So there you go! Good luck!


Samsung Galaxy S4 Old Emails Showing Up as New

Not sure if this will work on the S4, but it seemed to do the trick with my wife's S2, and my S3: change 'recent messages' (email account settings) from 25 (the default) to 'total'.


Can RAM and ROM be increased after rooting a device?

It can be possible by upgrading Hardware only. But the existing memory can be used wisely by rooting your device.

For example, to get some free space,

ROM (can remove unwanted System apps)
RAM (can swap some of your unused app memory from RAM to secondary storage (SD card); try out RAM Expander for instance )

Note: we cannot expect the same hardware's performance while swapping
 RAM.


How dependent are stylus devices on software?

For a start, you can't install "vanilla Android" on a non-Nexus device. See Flash a smartphone with vanilla Android ROM for more. The closest you can get is a custom ROM that was originally based on AOSP and then ported to your device, such as Cyanogenmod.

The custom ROM's documentation should say whether it has the drivers for the stylus, and if so, it'll work just like a more precise touchscreen. You still won't get any special stylus features (like extra buttons or pressure-sensitivity) in this case, though. There's no standard Android interface for such features, so they rely on the vendor's proprietary library and interfaces for apps to support them. Again, you should check the custom ROM's documentation to find out how much is supported.


Even with WiFi turned off it is still the biggest battery drainer (S5 Mini)

Navigate to Settings -> WiFi -> Advanced (under the context menu) and ensure that Scanning always available is not checked. This feature 'Let's Google location service and other apps scan for networks, even when WiFi is off'.

This is most likely the cause of the battery drain. To further reduce WiFi battery use, you could change the Keep WiFi on during sleep option to Only when plugged in or Never. However, this may prevent you from receiving emails, messages and similar notifications while the device is locked.


How does AOSP on a dual sim smartphone handle data?

According to digitalcitizenlife, you have two screens you can change this under the Default Mobile Data option,

There is also a Huawei FAQ about this, "Dual SIM settings

Android browser should automatically back up any passwords on your Google account (the college email, but signed in on Google). The first step I'd try to recover your google account.

Hopefully you had some alternative contact methods (secondary email, registered phone number, chosen account trustee etc). These allow you (sometimes) bypass password entry provided you answer any questions accurately enough.

In my last use of the recovery option asked me previous Google purchases and significant email communications and it let me in after 24 hours.

Beyond this I am unsure if rooting your device will be successful as major parts of the OS are


Can you run Linux command line apps on Android?

"Rooting" allows you access to the internal Android environment, which of course consists of more than just the Linux kernel.  So you are running Linux, but you should consider it as though you are running under a different distribution than say Debian or Redhat.

There's a different set of standard libraries and some files are in different locations.  At least on my Droid ext2 support is not built-in by default.  There is also no init or cron.  The full set of Linux modules is not available unless you compile them yourself and put then in /system/lib/modules.  Important ones you may miss on standard ROMs are cifs, ext2, tun, and others.

Most, if not all, phones running Android are ARM CPUs.  So the binaries you run on them must be ARM "EABI" "soft-float" binaries.  If you have the source you can cross-compile whatever utilities you need, but read on.

There are many standard commands and utilities available in the /system/bin directory such as grep, ps, cp, rm, mv, ls, ip, even vi.  You have enough to get by until you...

...use the "Linux Installer" utility to install a chroot'ed Debian environment.  Debian has supported ARM for a while.  It takes some work, but if you can root your phone, and have a sizeable enough SD card, this is the way to go.

This is close to a standard Linux system and under it you can install and run Ruby.  Of course CPU and RAM limitations come into play.


The ICS' config screen says it's for low security situation. It shouldn't be used for cases where you have sensitive information, and more for the casual user that uses their phones for personal photos; not the type who carries their company's next secret world domination plan. While face unlock is a gimmick, it's a cool gimmick nevertheless, and I'm sure it will be used by the casual users who values convenience more than security, as it is basically an automatic unlock for them.

  If it fails to unlock automatically, is there a fallback password/pin
  mechanism to unlock the device?

Not sure about that; but all stock unlock mechanism has a fallback to unlock using your Google Account username and password. I don't see why they wouldn't do that with face recognition.


USB host mode with class compliant audio interfaces

I think USB Audio support was initially built into Android 4.0 ICS but there may be earlier implementations and not every hardware that supports USB OTG and runs ICS+ supports USB Audio.

The capability of an Android device to handle USB audio mainly depends on the Kernel running on your System and your hardware being able to handle USB devices (USB host). Custom kernel and ROMs can void this. I have been able to connect (to my stock Samsung Galaxy Note 2):

an Alesis I/O4 USB Soundcard from Alesis (4in, 4out, phantom power)
a Harman/Kardon v1 USB speaker system and
a Shure x2u soundcard (1in, 2out, phantom power)

all playing stereo (Alesis could not be configured to play on all four channels) and the soundcards also record (alesis recording 4 tracks in sync) in very nice quality. I used Urecord (mono/ stereo) and USB Audio Recorder PRO (multitrack) and I have been told that Audio Evolution is also able to record from a USB source.


How to add app shortcuts to home screen on the Note 9

First, check if your time and weather widget are taking too much space.

To check: long press on that particular widget and you will see how much of space it is taking.

If you are using two different widgets for time and weather, it's recommended to use one by choosing it from:

Tap Widgets from lower settings appearing on your screen,
Right swipe widgets to see more,
Choose Weather from widgets and choose widget as I am using in above pic, and it uses less space.

You can also change your App screen grid by going to Home Screen Settings on the lower right of the screen (as appears in your uploaded picture).

Now, choose from menu.

To add new shortcuts it is very useful that you do it by long pressing on any app from App drawer, dragging it and releasing it whereever you want to place that app.

Note: you can only put apps on the blank space of your Home Screen. To check space you have to long press widgets (that are on your home screen, such as Clock, Weather widget, Google Search, etc.)


Under what path is the data for Firefox extensions stored?

On Android 10, Firefox 68.7.0

/data/data/org.mozilla.firefox/files/mozilla/1q4ydoub.default/extensions

I am not sure if the number before .default is specific to version or something else

For more details, see Firelord's answer here Where Firefox for Android is keeping add-on generated files?

Edit: You can paste file:///data/data/org.mozilla.firefox/files/mozilla/1q4ydoub.default/extensions in the search bar to see details of extensions, size, last modified time stamp


It's either Floating Toolbox (Floating Launcher)  which is a shortcut application or the Samsung Galaxy S5/S6 Toolbox. These
Floating Toolbox apps gives you access to your apps from anywhere by pressing the Floating button.

Here is a link to the Floating toolbox app:

You should be able to disable / uninstall them from settings -> application manager.


Every single application constantly stops working

I have the same phone. I had to do a hard reset. By doing this its like your phone is brand new straight out of the box. No mobile codes which pretty much leaves your phone open.

When you get a new phone, they mess with it first before you get it in your hands. They put in codes for their network so all will work properly. When I did the hard reset I couldnt send MMS nor recieve them either, but by downloading GO SMS, I looked at their settings and was able to get my phone right again.

If you can't get into the settings to do the factory reset or anything else, then this is the next best option:

To do a hard reset turn your phone off.
Turn it on again holding the power button and both volume keys at the same time until you see the Samsung flashing logo.
Release all buttons and a little cute 3D android will show up. You then will have the option on what you want to do.
Remove your SIM and SD card, or they will be erased along with your phone.
Your phone will be brand new again.


Official Facebook Hello contacts/dialer app login only says "104"

"We're moving on" is all Facebook has said since then, adding "We will be deprecating Hello in a few weeks." minus a reason, from an unknown anonymous Facebook employee author.

For some reason Facebook did not tell users who installed the HEAVILY advertised "Hello Dialer" application about (maybe with another ad equally) that they're forgetting the idea now: https://newsroom.fb.com/news/2018/07/hello-tbh-moving-on/.

The reason you did not find information, is that recent news suggests the application in question has been deprecated officially in a quiet press release, in their news article I archived to report at http://web.archive.org/web/20190522194837/https://newsroom.fb.com/news/2018/07/hello-tbh-moving-on because of the secrecy, as that is fairly well hidden for a large organization, and had not been given good meta-data information, to be indexed in searches with priority.


Gmail app: how can I change the sender address?

When composing the "From" is a dropdown menu.  It has all the accounts you've added via the webmail interface, and it's had this feature for a long time (you shouldn't need to upgrade).


I would think that it is system bug. Huawei, Xiaomi and (non Nexus) LG have worst implementations of Android. There are tons of bugs in their customizations.

I don't understand how they can pass Google's certification.

Disclaimer: I'm developer so I get many bug reports from users owning those devices.


Android Marshmallow: How to disable vibrate on call connect?

Open the dialer and click the 3 dot menu in the upper right corner and select Settings, then Sounds and vibration, under "In-call vibration" there are options for Vibrate on Answer, Vibrate on Call Waiting, and Vibrate on Hang up, select or unselect as desired.


how do i manually copy my cellphone numbers from my cellphone to my computer

There are multiple ways to achieve that, some are depending on the OS your computer runs.

Simple VCard exchange

Open your contacts app, open its menu. You should find an item to export your contacts to your device's SDCard (usually in a sub-menu called "Import/Export"). Hitting that will write a file named 0001.vcf or similar to the SDCard toot directory.

Copy that file to your computer. Most contact applications are able to open/import the file, which is using standard VCard format.

Specific application

There are specific applications available for that task, often having an Android app for the device and a specific computer counterpart. The probably most famous of them is MyPhoneExplorer, which not only deals with your contacts, but also calendars and much more. This software requires MS Windows on your computer.

Other Synchronization Services

There are plenty of different "servers" available to synchronize Contacts (and Calendars, and more) between devices. I e.g. use ownCloud with my devices, which gives me complete control over my data. As with the previous item, this requires a local app and a remote component.

Others

You can find a list of possibilities for synchronization in my app listings, specifically: Synchronization of Calendars, Contacts, etc.. My list for Backup apps also has a dedicated section on contacts. Those backups you can copy to your computer then as well, but rarely import to any computer program. If you want to directly access your Android's contact lists from your computer, you might also wish to take a look into Manage your Android Device from your Computer.

Huawei ideos s7 slim Honeycomb update - is it possible somehow?

XDA has nothing except for some attempts at getting Gingerbread on it.

I would expect you're out of luck since Honeycomb wasn't open-source, and porting was therefore very difficult.  It's possible that someone will mod CM9 (Android 4.0) to run on it, so I would wait and see.


Is disabling all the wireless connections the same as enabling "airplane mode"?

I didn't dig into the source code for authenticity so consider this as an educated guess. I noted that when turning on Airplane mode only the radios mentioned in the key airplane_mode_radios1 are turned off. That is, the communication through those radios cease to exist. The list of radios in the value for that key I've seen in my devices are: cell,bluetooth,wifi,nfc,wimax,

where,

cell: cellular radio (used for mobile network connectivity)
bluetooth: used for bluetooth connectivity
wifi: used for Wi-Fi and portable hotspot connectivity
nfc: for NFC
wimax: ??

So yes, if you individually disable all the radios listed in the said key in your device then you would effectively be achieving the final result of Airplane mode.

If it matters, I found the value for the said key using adb through the command:

adb shell settings get global airplane_mode_radios

1 The key can be found in the table global of database /data/data/com.android.providers.settings/databases/settings.db. In Android 6.x, the location for the key is /data/system/users/0/settings_global.xml

How do I set Google Photos to ignore videos?

In the official Google Photos app, you can't disable backup of videos per se, but you can exclude folders having videos from being backed up. That can be done like this:

In the "Device Storage" view (accessible from the swipe-in sidebar), look for the "cloud" icon to the right of the folder name.
If the Cloud icon is blue with an up arrow on it, backup of that folder is enabled. Tap on the icon to disable backup for that folder.
The Cloud icon should now become white with a slash through it. Congratulations! Backup of a folder has been disabled successfully.
It might happen that your videos are intermixed with your photos, especially if they have been shot on your camera. Move the videos to a separate folder using a file manager app, usually "Videos", and disable backup for that folder from the "Device Storage" view.

This will disable Google Auto-Backup for the selected folders only, leaving the rest unaffected.

It's easy to achieve a similar workflow with an off-the-shelf barcode scanner app such as ZXing's Barcode Scanner. After scanning a barcode in that app, you can press a button to copy the scanned text to the clipboard. After switching to your other app, you simply long-tap the text field to paste the text into it. It's a few more screen taps than you're imagining, but that's the easiest way.

There's also a keyboard app that has a button to scan a barcode and enter the scanned text as if typed in. It's non-free, and requires replacing your soft keyboard, but Barcodescanner Keyboard lets you shorten the workflow by a few taps.

Any better solution would require some kind of bespoke development, whether that's modifying the target app or making a custom ROM.

Do I have a virus on my phone? A message from an Android app says so

It is possible to have malware on Android, although these usually 'infect' a device through downloading and installing apps from un-reputable and/or warez sites. When installing any app you should review the permissions and not blindly download/install an app simply because it looks ok.

It is possible that the message you received is from a malicious app or an app trying to get you to install malware. You can install a security app such as Lookout or Avast and they will scan your device for issues/malware. Be aware that anti-malware apps such as these can report false positives, and they may not detect all issues so you need to use common sense and ensure you only install apps you trust.

Can adb be used to recover SMS messages while in permanent "Safe Mode"?

Try this:

cat /data/data/com.android.providers.telephony/databases/mmssms.db > /sdcard/mysms.db

Which copies the SMS database across to the SDCard.

For the Telephone database,

cat /data/data/com.android.providers.telephony/databases/telephony.db > /sdcard/mytelephony.db

Its a very old trick, to pull in the databases without root. It is not guaranteed to work across all ROMs depending on how the directory permissions are set.

App To Scan Hyperlinks|Content On A Web Page?

Scanning a hyperlink on a page (visually, as QR code usually is) can be problematic.  After all, almost every link on the page you're reading does not present a full URL that can be used by the handset (e.g. http://www.google.com doesn't bring you where it says that it does).  In light of this, the Chrome to Phone extension for the Chrome browser can send  a page to your phone where you can bookmark it.  In addition, you get several other nice features (send a highlighted number to your phone's dialer from the browser or launch Google Maps links on your phone from a browser link). Very handy.

If you aren't thrilled with Chrome, Firefox even has an add-on

How to copy file from PC to android tablet?

If you have the Android Development Kit (See Bottom) then there is a super easy way to install an application from a file. All you need to do is start up a Terminal and type:

adb install -r <your.apk>

the -r function will replace an existing application with the same name.

No fumbling around with SD cards and no searching your phone for transfered files. If you are an avid Android user then I recommend getting the ADK.

Can I "Wipe data/Factory reset" a phone that doesn't even boot via USB?

I've seen such an issue before, but it was a samsung device.
I do not have a cookbook solution for you, just some points to check:

Is the powerbutton still working? Did you have issues with buttons before? On the samsung we had to create a special plug from a cable and a 3k resistor. This brings the samsung phones directly to download-mode where you can flash and or reboot.

Is your battery still ok? Can you replace it (quickly exchange with a friend) or is this not possible with your phone type?

Is your charger ok? And the cable? Try another one and leave it on for a while, a dead battery needs a bit of time and very slow charge, before it can go back to normal charging.

Good luck


Is there a way to start a torrent on my Android stick remotely?

You might want to take a look at Torrent Manager:

  Torrent Manager allows you to take control of your remote uTorrent, Vuze / Azureus, Transmission and Deluge clients. With this app you will be able to list, add, remove, start, stop and manage the queue order all your torrents from your remote desktop.

Other, similar alternatives are e.g. TorrentToise and Remote Transmission (Transmission is a torrent client on Linux, so this is not for you). Find more on AppBrain (or Google "Tiles" Play) by following their related apps ;)

You can easily manually switch carriers in Project Fi:

Head into the Phone Dialer app that came with your Nexus phone, then type in these dialer codes to manually switch carrier:

Sprint = *#*#FISPR#*#*
T-Mobile = *#*#FITMO#*#*
US Cellular = *#*#FIDAN#*#*
Auto = *#*#FIAUTO#*#*

You can also download the Fi Info app, which automates the process a bit with a widget (I use it all the time).

Battery goes down from 100% to like 80-75% so fast

From the question comments, you have not calibrated your battery (in a long time or ever).

You need to do a proper calibration:

Do a full charge of the device's battery.
Use the device until it turns off on its own. Do a full discharge of the battery. One neat trick is to get some game that has wakelock (does not let the screen turns off) and leave it running with the device on a well-ventilated place.
After the device dies of low battery, wait for it to cool down and turn it on and use it a bit more. When it refuses to turn on at all, its fully discharged.
Plug it in and let it charge to max.

This will set the flags for FULL and EMPTY battery, and the meters should be accurate.

If the problem persists, your battery may be damaged. If the device's battery is still under warranty, take it to the service center.


You can accomplish this with an app.  Look up Volume Lock in the Google Play store.  If you don't want to prohibit access to your phone and he is extra persistent, you may need to install another app to password protect the Volume Lock app.  AppLock does just that.


Just try these fastboot commands:-

adb reboot bootloader
fastboot oem unlock-go
//To Toggle
adb reboot bootloader
fastboot oem lock-go

Is it beneficial to turn off GPS (or turn location to battery saving) in Marshmallow?

Yes, Any radio being turned on will cause some drain. It really depends what apps you have using that location. If there are more number of apps accessing your location, it will definitely cause your battery to drain.

Keep location services and GPS high accuracy location off unless you need it. Other Apps in foreground/background will unnecessarily constantly ping GPS if available rather than cell towers for location. Cell towers location is good enough for most situations, unless you have to run apps like Uber, Navigation, etc.


Neither taking out the sim card nor a factory reset helped

The following was suggested by Nokia itself. But turns out they didn't think to suggest doing both at the same time.
Although it can be far easier - just turn off Mobile Data, then check for updates. If it's not enough, also restart the phone while keeping Mobile Data off. Suddenly you get updates.
I'd chalk it off as a bug that lets the phone provider save bandwidth for itself even though you actually use WiFi for updates.


Can I run ICS on the Samsung Galaxy S+ I9001?

The Galaxy S Plus i9001 looks like the i9000 however it has completely different internals:

side by side comparison at gsmarena.com
different CPU (1.4GHz Qualcomm Snapdragon vs. 1GHz Samsung Hummingbird)
different GPU (Adreno vs PowerVR)
different baseband modules (the i9001 has faster HSDPA)
better battery, less internal space (512MB vs 2GB for the i9000)

Most importantly, the i9000 is well supported while the i9001's community support is rather poor. There's no official CM port for it. See the i9001's forum at XDA-developers.com. Regarding the approaches: Yes, you can use the same tools and your knowledge for the i9000. Just not the same ROM downloads.

How do I download the music from my computer to my samsung moment?

There are many ways to (semi-)automate the process. I'm assuming you don't want to use an app to manage this. (There are dozens. I expect some other answers will suggest some.)

I also assume that you know how to connect to your PC and turn on "USB Storage".

Just copy your music files to your SD card. The music player will find the tracks wherever you have them, but you should probably put them in a "Music" subfolder so that you can find them easily.

It's as simple as that.


Permanently indicate to Market an application should refuse upgrades?

Titanium Backup Pro can do what you want. (Yes, you must buy PRO. The feature is disabled in non-pro).

Scroll to the app that you want to unlink from Market
Long-press on the selected app
Click Detach from Market

I can't get it to work on my phone, but maybe it'll work for you.


Daydreaming -- does it decrease screen life?

As life of LCD screen is measured in hours of its usage, keeping screen turned on does consume some of its life hours.

Not connecting via usb since latest update

What protocol does the connection to your car radio use? I can't exactly speak for the GS3 but this is for stock Android so it may be similar. Go into Storage under Settings and hit the menu button (or the menu overflow) then select USB connection (or similar), make sure MTP (you probably need this one) and any other protocols you need are checked. There may also be a Mount USB option present if that the former does not work.


Are there any Android tablets that have the "negative colours" accessiblity feature like the Samsung Galaxy S III phone has?

Yes, the Samsung Tab 3 8.0 and others. The Samsung Galaxy S III phones got this feature quite a while before it was part of the feature set of the Samsung tablets. Other Samsung tablets like the Note also appear to have this feature now, as do later versions of the Galaxy phone. I still haven't come across any other manufacturer who includes this accessibility feature with their Android tablet range.

(for any users who need high contrast to read or have a light sensitivity problem, this feature is a life saver)


How to save files to external SD card on a non-rooted Android?

Filesystem level write access to physically external SD card without rooting phone is not possible since pre-KK days. However apps can always (with or without Storage permission) read and write to their private directories on shared storages. So you can move files to /storage/extSdCard/Android/data/.

On Android 6+ external SD card is visible at /storage/[UUID] where UUID is that of filesystem. This filesystem path is only available for reading (to apps with READ|WRITE_EXTERNAL_STORAGE permission granted) and traversal (for all apps). Latter case is to let apps read/write to their private directories. Like internal emulated filesystem, permission control is implemented through mount namespace and everybody (9997) GID. SD card is mounted with three distinct VIEWS of different permissions:

vold creates an isolated mount namespace for every app and depending upon app's status of Storage permission, bind-mounts a VIEW to /storage/[UUID]. For detail see What is /storage/emulated/0/? and What is the “u#_everybody” UID?

Since none of the three VIEWS has write permission, apps don't have filesystem level write access to public directories on external SD cards. However apps - like mostly file explorers - which make use of Storage Access Framework (SAF) (or Scoped Directory Access on Android 7+ or Scoped External Storage Access on Android 10+) are able to create and delete files on whole SD card.

USB OTG is treated almost in similar fashion, but with one prominent difference:

  "MOUNT_FLAG_VISIBLE means the volume is visible to third-party apps for direct filesystem access.
  ...
  transient volumes like USB OTG devices should not be marked as visible; their contents should be surfaced to apps through the Storage Access Framework."

So USBs aren't exposed as VIEWS, instead apps see /storage/[UUID] (which is not an actual) filesystem path through SAF for both reading and writing. That's why contents of removable media aren't available through MediaStore too. Neither available to apps through APIs:

  "The returned paths do not include transient devices, such as USB flash drives connected to handheld devices."

Multiple external storage devices:

  "External storage devices surfaced through these APIs must be a semi-permanent part of the device (such as an SD card slot in a battery compartment). Developers expect data stored in these locations to be available over long periods of time. For this reason, transient storage devices (such as USB mass storage drives) should not be surfaced through these APIs."

However Adoptable Storage is always visible to apps, whether SD card or USB.

Can a lost rooted/unlocked phone be decrypted by a thief?

If your phone is encrypted, then it cannot be decrypted without having access to the decrypt option in Settings. And since you have a fingerprint lock set up, as far as my knowledge goes, you are safe - no one will be able to access your data, even if you are rooted. Decrypting the phone externally should require extensive hacking algorithms and knowledge about the phone architecture, and I doubt anyone will spend that much time.

If, however, the thief wipes your phone (factory resets it) from TWRP, then all the data will be lost, which again means that your data will not be available to the thief, and you are still safe.


Galaxy S5 charging slowly despite 'AC' and 2A charger

Your understanding and measurements are logical and I can't say why your battery should charge slower compared to the earlier one

One thing you may try is to backup your device and flash latest stock ROM or custom ROM which has a kernel that permits higher rate of charging

If that's a lot of work, change the USB cable to a thicker one. See my answer here for details

(I am not affiliated with the product but a happy user. I keep buying those when on discount and gift to friends. All have uniformly attested to better charging rate)

Edit : It could be a faulty USB port too. You could try getting that replaced


Can't authorise android lenovo tablet in USB debugging mode

Resolution
Possible solutions if adb devices shows a device as unauthorized:

C:\Users\JohnDoo>adb devices
List of devices attached
17310D821D  > unauthorized

Disconnect USB between PC and device
Stop adb server by entering adb kill-server in command window
On device use Revoke USB debugging authorizations in Developer Options
On PC delete adbkey file in user directory, for example C:\Users\JohnDoo\.android
Reconnect the device to the PC
Open a command window and enter adb devices. Watch the device's screen for any Authorization message and allow the connection.

The device should now show as device:

C:\Users\JohnDoo>adb devices
List of devices attached
17310D821D  > device

If the above does not help, re-installing adb and or USB drivers may help.


Is there an alternative to Bouncer- Temporary app permissions?

I suggest using  Android Mobile Device Hardening which:

list installed apps and their dangerous permissions
revoke dangerous permissions for all Apps
list applications that are device admin


Can't get to fastboot. nor twrp nor OS - Xiaomi mi 5X/A1

Have you tried using adb?

If you haven't got it already, download the SDK tools for windows from https://developer.android.com/studio/ under the "Command line tools only" section, and unzip it where you want.

Once you've done that, open a command prompt in the platform-tools folder within the SDK directory. The command

adp devices

will tell you that your device is connected. Then you can try

adp reboot recovery

If that doesn't work, install the universal adp driver and try again.


What is this application from the Play Store?

There seems to be a similar thread here, so you aren't entirely alone. Just disable that app for now since it's bloatware anyway!

Lollipop update on MotoG causing no service for sim card

I have a phone with the same symptoms, this worked for me, but the problem still reoccurs so I'm trying to find a better answer.

http://www.thecellguide.com/moto-g-noservice.php

In brief:

Go into Settings -> Storage; tap Cached Data and select Ok to clear data
Go into Settings -> More -> Cellular Networks -> Preferred network type

Select "2G"

Turn the phone off, wait 10 seconds and then turn it back on.
Go into Settings -> More -> Cellular Networks -> Preferred network type

Select "3G"

Select Network Operators -> Search Networks
Select the correct carrier and you should be all set.

I'm not sure if that article was written with the LTE version in mind, so I follow the instructions and then switch the preferred network type to LTE.


Titanium Backup is a backup utility for Android that backs up your system and user applications along with their data on external storage of your choice. It is a leading Android application that uses root access to pull all your important applications and data from the system partition and stores them for future restoration. Whether your phone is corrupted or flashed with a custom ROM, Titanium Backup can save the hassle to get your phone loaded up just like it was before.

TWRP is an open source, community project. We also have a large support community with many people who are willing to answer questions and help people with their devices either through our IRC channel or on forums like xda-developers.

A custom recovery is used for installing custom software on your device. This custom software can include smaller modifications like rooting your device or even replacing the firmware of the device with a completely custom "ROM" like OmniROM.

A custom Android ROM refers to a phone’s firmware, based on Google’s Android platform. Android is open source and therefore any developer can edit the code, recompile it, and re-release for a wide variety of devices. Users can install ROMs to change a device’s appearance and behavior. ROMs are developed by the Android community, often times by a group of core developers who do this purely out of passion for modding. This means that most are completely free. Custom ROMs are available for phones, tablets, media players, smart watches and almost any type of device running Android.

Notes

You don't need to root for installing twrp and custom rom using twrp, but sometimes required to unlock bootloader to flash twrp. For a complete access and customisation, it requires root access on any ROM.
You can backup all your user app(apps installed from play store) data to any android version, and can restore using titanium backup app, which requires root access. For system apps, both should be in same android version is possible.
many custom roms are available on open source forums like xda. Search the one for your device. Look for some official builds like Lineage os, pixel experience etc. Developer will releases updates as nightlies, which resolves initial bugs, and makes more stable in future.
Gapps for any custom rom can be downloaded from open source platform like opengapps.org.
Rooting may voids your device's warranty. And you must be careful at each step. Because, any mistake can lead to make device brick. Device bricking means, it will continue in repeated on/off state
(Bootloop), won't turn on, boots to recovery only etc, repeated app crash while usage.
You can perform this ,
If you're going to use titanium backup app , then backup all your user app data using titanium backup to SD card or USB stick through OTG. Flash twrp and custom rom. On booting to custom rom, install titanium backup, and restore app data.

If you are using twrp method, you can backup your current rom using pressing backup part in twrp. After flashing custom rom, you can restore data backup which is done by twrp (nandroid) using titanium backup.

A backup of current rom using twrp is recommended, if anything happens in between, you can return to current os without losing any data. Back-up to SD card or USB, don't do it on internal storage, which may get erased.

Some instructions say hold Volume Down + Power 5 seconds to open the boot menu. On a ChaCha with software version 1.57.161.3 opens the boot menu immediately; I just hold Volume Down and get the boot menu within a second.

Booting works differently depending on which Android and ROM version you have. Open Settings, About this phone, Software and add in your question which version you have. On another ChaCha with software version 1.54.401.3 I get re reaction at all with holding Volume Down, but maybe the button is physically broken.

Update:

So 2.3.3, and presumably original ROM installed?

HTC did release updates from Android 2.3.3 to 2.3.5 -- see https://en.wikipedia.org/wiki/HTC_ChaCha
Which phones got that update was supposedly Carrier-specific. I've seen mixed info on forums and official. On 12th June 2014 I tried (manually) to access the update servers listed in the ChaCha device props files (the ones used for OTA = Over The Air/half-automatic updates), and it is possible that OTA no longer works for ChaCha.

(I've seen the Facebook button start making trouble, and that slows down the phone to almost unusable levels -- and then it needs either repair or if you install a ROM that ignores the Facebook share button.)


Why is Google Maps telling me that Offline Maps aren't available?

It turns out that just because you can see and use a map online, that doesn't mean that Google will allow you to make the area available offline.

Offline maps are only currently available for certain countries, and Brazil isn't currently one of them, in fact it seems to be a fairly odd selection.

Google have published the full list of countries that it's available in here: Maps for Mobile - Offline Availability

EDIT: note that in a July 2013 Google Maps update, Google made offline maps into a hidden feature with no menu option any more. More about how to make maps available offline here: Get offline maps in new Google Maps

Unable to activate USB debugging after upgrading to Android 5.1.1

Open settings and go to storage
Press menu and go to USB Storage Mode
Change to USB or MTP (NOT Charge only)
Disable and re enable Development options with the 7 clicks on Build Number

Screenshots (click images for larger variants)


Here is what I ended up doing, it works well:

On your computer's Firefox, install the GMapToGPX bookmarklet.
Prepare your itinerary with Google Maps Itinerary.
While still on the Google Maps page, click on the GMapToGPX bookmarklet. It opens a GPX conversion dialog.
Click on the blue tab buttons to make them read like this: "Route Track Points About". It will not work otherwise.
Copy-paste the XML text in a new file, for instance myitinerary.gpx
On Android, install Maverick.
Copy your GPX file to /sdcard/maverick/tracks
In Maverick, select the track file
Scroll your way along the route at appropriate zoom levels to store the tiles in the cache.

The free version of Maverick allows 3 tracks files.


How to set the notification dots on a Moto G6?

I am also having this issue.  Notification dots are enabled on all apps but don't work.

I do not have any 3rd party notification apps.
I have cleared cache and data from the "Moto App Launcher" application and restarted.  No difference.

I did, just now, download an application for notifications and it works.  So annoying.  Moto App Launcher obviously has some issues/flaws.


Well, delete all your google accounts restart your phone better re-insert the sim card. Go to gmail create your account again then try opening play store. If it doesn't work sync again! :)


While I do not have an answer for this strange behaviour (which I'm experiencing as well), I can say that a whole reboot may be skipped. In most cases, in fact, renaming the file you wish to transfer will make it visible on your PC as well. Additionally, if you wish to embark in the journey of installing adb on a Mac, you'll find that:

adb pull "android_file_path" "path_to_copy_the_file_to"

will be able to copy the desired file to your computer, regardless of it being visible on Android File Transfer or not.

What functions are in the ROM of an Android phone?

Well, the OS is in the ROM, to start with.

You're suffering from a terminology problem: "ROM"s these days are all typically Flash memory, which is erasable and rewritable, but not byte-by-byte. So the OS may even live in the same physical ICs as the 'main' phone memory.

Basically, custom ROMs can enhance/modify/break EVERY aspect of your phone's operation. There is a separate 'radio rom' which includes the low-level drivers for the wifi/gps/3g/gsm/bluetooth functions, and these typically aren't 'customised' but you may still find newer versions available that can improve certain aspects of your phone.

How to Boot to Recovery mode on a Lenovo tab M8 FHD Tablet?

As soon as the device goes on release the power button but continue holding the volume buttons.
Hold the volume buttons till it enters into recovery mode.


Missing device driver for "Android 1.0" in Device Manager while in HBOOT menu!

Installing the driver from the XDA Dev website should solve this issue.

(There is also a driver and a tutorial on the Unrevoked website. But the this driver didn't work for me. While the driver from the XDA Dev worked every time.)

You essentially need to download the adb_driver_htc.zip file and view the hardware ID of your HTC device (Properties dialog of the device in Device Manager) and make sure it matches the ID in the INF file for this driver. You then need to update the driver for the device (in Device Manager) with the missing driver (yellow triangle with exclamation mark).


Assuming your device is rooted there is a ppa for adb and fastboot.

Type:

sudo add-apt-repository ppa:nilarimogardwebupd8

sudo apt-get update

sudo apt-get install android-tools-adb android-tools-fastboot

Now you should open a shell/rootshell and type

adb

followed by

adb devices

Then your Phone should show up. To delete the app and odex file type:

adb rm /path/to/apk

adb rm /path/to/file

or

adb uninstall [-k] packagename

The option -k keeps cache and data on your phone if you want to.

Then end this process by using

adb reboot

BlueStacks 4 Hyper-V does not finish booting while Hyper-V is enabled

Yes, this is because I have enabled Virtual Machine Platform and it implicitly enables Hyper-V, because Hyper-V is a native hypervisor, as long as it is enabled Windows boots as a virtual machine and can only access the emulated CPU and can't access the physical CPU, the emulated CPU doesn't support VT-x, so as long as Hyper-V is enabled performance of hosted hypervisors will decrease.
And I found out that Windows Defender Device Guard is also enabled and it also implicitly enables Hyper-V.
So I used these commands in elevated cmd to truly disable Hyper-V:
bcdedit.exe /set hypervisorlaunchtype off
dism /online /disable-feature /featurename:VirtualMachinePlatform
reg add HKLM:\System\CurrentControlSet\Control\DeviceGuard /v EnableVirtualizationBasedSecurity /t REG_DWORD /d 0
shutdown /r /t 0

After that I can't open BlueStacks (Hyper-V), so I uninstalled it and installed the version without Hyper-V, which is faster because of VT-x.


What is the difference between twrp-[version]-[phone].img and twrp-installer-[version]-[phone].zip?

The answer becomes clear once you read the install instructions:

You will need both files to install, as your device (OnePlus 6 aka enchilada) is an A/B device and thus has no recovery partition (recovery is part of the boot image there) – which means you cannot simply flash the recovery image using fastboot. So you download (or push) the ZIP to your device, then temporarily boot TWRP (fastboot boot *.img) and from there flash the ZIP.

HTC One S vibration keeps getting turned on for normal profile

In my ICS (on LG Swift hardware) the switch to "ring" profile occured on every answered call during daytime. Somebody else at Polish LG forum complained about switching to "quiet" at night.

SOLVED: After some reading and a simple experiment I found that it is the system app to switch profiles for the nighttime (settings->sounds->"silence time" in my LG). This is a buggy app: after any event requiring sound on - like answered call or so -- it switches to the scheduled profile, even if it was overriden manually.

To make clear: I have "nighttime" quiet setting, so after manual switch to "loud", upon first call it automatically returns to "quiet". In the daytime, when quietened manually, after a first call it returns to "loud".

Switching this option off helps.

P.S. I have read about problems with tasker after upgrade - maybe it is some more general bug (or feature making some apps incompatible)

Running android apps directly on ubuntu or gentoo

Memory requirement (for HDD) for Android based tablet?

This is really an "it depends" answer. If you are only installing applications and streaming any media you consume, 16GB is sufficient. If you are copying media locally, 32GB should be a minimum.

By way of example, the tablet I was using on my last vacation only had 2GB used. My son's was full at 16GB with the movies and TV shows we'd copied on to last him a week and he ended up watching the same shows over and over.


Can I safely do a factory reset without losing root?

Recoveries like TWRP and Philz Touch checks for root verification and in the scenario of you losing root after  factory reset, boot into your custom recovery, attempt for a normal reboot and the recovery will offer to root the device. Take the offer. Come back to Android and install SuperSU from Play Store as usual. This worked well with my Android 4.2.1, 4.4.2, COS12 and stock Android 5.1 ROMs.

Note: do not use the said approach on a ROM running Android Marshmallow. It may cause boot issues which you might not be able to solve unless you do a clean and full flash of a device specific ROM or manually reverse the steps TWRP used to root the device.

As of now, to root a ROM prefer the flashable zip for SuperSU stable and flash it through your custom recovery. In case of installation issues, refer to this XDA thread.

Related: I've installed a custom recovery image, but not yet rooted my phone. How can I install SuperSU and subscribe to automatic updates?

SuperSU app offers to move itself into system partition which would make it a system app and invulnerable to any factory reset. The option is available under its settings as Install SuperSU into /system.

(As of now however, for ROMs rooted with system-less root mode SuperSU doesn't provide the said option.)

About battery drain, per my experience with it in Android 4.2.1, 4.4.2 and 5.0.1 I can recommend Greenify app in Boost mode. Boost mode requires Xposed Framework1 installed.

How to fix setting Android display brightness to 0%

Is it the case that you can't see anything at all, or is it just really, really dark at the moment? Most LCD screens will show something faintly, even without a backlight, if you can get them in the right light.

If you can see something then the easiest way to turn the lights up (if you're using Android 1.6+) is to add the Power Control widget to the home screen and then tap the far-right button on the Power Control Bar, this should turn the brightness to half and then full, and you should be able to get to the rest of your settings then.


Samsung Galaxy Ace GT-S5830 neither goes into Download Mode nor RAM Dump Mode

Plug it into your computer and see if by some offshoot chance you have adb available.  If so, run a adb -d reboot-bootloader to reboot into download mode.

Where are extra keyword tags for photos stored?

The tags are stored through the media's content provider. In layman's terms, the content-provider is a way of Android interacting with a database backing store.

The location can be found in this directory:

/data/data/com.android.providers.media/databases

Which is Sqlite3 database that has the following information stored in it, or rather, a combination of certain columns, not all of them, due to the way developers can optionally add the fields of the data to be stored. (If you're un-rooted you will not be able to list the database - if someone can clarify this, just checked on Europa GT-i5500 which is unrooted and issuing ls fails)

If you have a look at this document that details the columns used in the database for the Media (that is a generic columns that is a de-facto within the database), it is combined with this other information

(Now at this stage, your brain is probably turned to mush looking at it but the pertinent information is in the column names which is found in the database)

As for the 'Tag' field you're referring to, quite simply, Android does not store them, there are replacement apps that replaces the stock version of the Gallery with extras such as the 'tag' field you're referring to. The most it can hold was the latitude/longitude/display name of the image and a picasa id in which it may get uploaded to depending if picasa is enabled with your account.

How can I switch out of "Internal Beta" version in Android App Store?

If you want to go back to the public version, you just have to leave the beta program. Leaving the beta program is done using the page for the application in the Google Play Store. Open the page of the app in the Google Play Store, and scroll down till you something like "You're a beta tester". Just below that title, there should be a button "Leave". Pressing that button will bring you back to the general public version.

Watch out, because some apps don't work that good if you want to go back in version numbers. Could be you have to reinstall the app afterwards.


Why does my phone on 6.0.1 download the entire app all over again when updating?

Google Play Store's App Updates vary by device's Android version. It's highly likely that the new updates being installed on your Android 6 device has huge changes in it to support latest Android APIs.

If you're downloading big games, there will be some extra size
 to be downloaded initially.
But if you're updating the app, it usually requires much less data.


"Unfortunately, Google Play Store has stopped."

From my personal experience, clearing the Google Play Store App cache may restore functionality. It's a very simple and quick fix that might help! :)


Where do I get my restored contacts from google?

You are not able to access those data directly on your device (unless it's rooted). There's a system app taking care for them, storing them in a database below /data (usually /data/com.android.providers.contacts). Apps like your contacts app or the telephony app interact with this via a corresponding service. To be permitted, apps need to declare the READ_CONTACTS resp. WRITE_CONTACTS permission in their Manifest file.


''insufficient space on the device'' – but my sd card has plenty space?

It has worked on Kitkat so may apply to older versions of Android

Settings > Storage > Phone Storage ( or could be Internal storage, wherever Google Play Services is) > apps > Google Play Services > Click Clear cache
(on the same page) Manage space > Clear all data > Manage search storage > clear now
press back button <- twice and you will end up on Google Play Services - App info page > press Force stop
Find Google Settings among applications or under Settings > Google settings > click on menu button on the page > Clear app data

Now you can launch Google play store and download desired application

Hopefully it works for you as well. Feedback will be appreciated.


Scattered Phone GPS Locationing While on WiFi

There are distinct sources of location information that are commonly called "GPS", but are more accurately called location services.

Sources in decreasing order of accuracy:

Bluetooth - Due to its short range, if you can hear known Bluetooth devices, you know you must be close.
Actual GPS - Your phone listens for satellites and computes its location based on distances to these satellites. This works best when you are outside with a clear view of the sky.
WiFi - Using wardriving and people using GPS, a map has been constructed of the world that basically tells you where you are based on the strongest WiFi signals you hear.
Cell - In addition to techniques similar to WiFi, cellular providers have additional technologies they can use to locate your phone, based on angles from antenna arrays, signal strengths, and distance estimations.

If your phone is using WiFi location, which is likely if you are inside an office building, the strongest WiFi signal will strongly influence where location services think you are. Since WiFi signals fluctuate quite a bit when people move around, doors open/close, furniture moves, etc., your estimated location will also change accordingly, which shows up as your character running around. The resolution of the WiFi database is roughly the range of a WiFi AP, which indoors is ~50m. The database is storage-limited, so there are likely only a few points around you, which explains why only a few distinct locations show up for you in the game.

How to start Android Lost app on stolen Samsung S4 after pushing it through Google Play?

There's no other way to REMOTELY ACCESS A phone other than Background Data or SMS... I could have said you open Pokémon GO and follow your balls around in circles until you find it but i went with the logical answer !.....    All remote access programs made for Android use Background data or Auto sync to control the device.. This means logging into the website and pressing connect to device over data... The Only Working Alternative is a Secret SMS that gets recognized and deleted by the target program, This usually contains control words like Locate Me 46432 ... Locate-Device-Password ...etc...


Google Glass LED won't turn on when power button pushed

There are a few possibilities about what the problem might be, ranging from the hardware locking up to a more fundamental failure.

You might want to start by doing a hard boot. Hold the power button down for at least 15 seconds, then release it. Then press the button again to try and turn it on.

If this doesn't work, you best bet is to contact a Glass Guide to have them troubleshoot further and possibly do an exchange. See https://support.google.com/glass/answer/3079854 for contact options.


Copying and remotely deploying a build across multiple devices

Using root and tasker rules you could pull your settings.db from a central point of your choice, but that would erase any settings.

A more elegant way would be a tasker rule that sets all the settings in the database.

For Wi-Fi AP you would have to pull the wpa_supplicant file from somewhere using the same method or use Linux tools to alter the config file.

Other settings would require finding associated config file or database and use above methods.

Cast Chrome desktop browser tab to Android device

You can install WebRTC Desktop Sharing extension on your Chrome browser for Desktop. Click on its icon → Chrome tab + Speakers → choose your tab to share → wait for the extension to give you a URL.

Use that URL into your Android device's browser. It will take few seconds to initialize everything and then you can have a real-time Chrome tab sharing from Desktop to anywhere.

Alternatively, if you are using Windows, enable Remote Desktop Sharing in it, setup a Remote Desktop connection and use Chrome Remote Desktop app to share the whole screen with Android. I haven't tested this one though.


Turn OnePlus 3 on with broken power and volume buttons

There appears to be no obvious workaround to power on your device, if neither your power button or volume button work.
You might be able to revive your buttons with some isopropyl alcohol and intensive button pressing. On the old Nintendo DS, you were also able to briefly revive buttons by breathing/blowing into the buttons and repeated button presses.
Another more advanced possibility, if you have nothing too lose, is to open up the device and see if you can bridge the contacts the button is supposed to activate. You might also find replacement parts on the internet.

Error: Facebook cannot download due to an error (923)

Do you have enough internal memory for the app to downloaded?! the facebook app is around 43mb in size...but on installing it consumes more than that!! But by android and Play Store conventions you need at least a minimum of 150-200mb free to be able to install an app apart from the size of the app you wish to install...so if you need to install an app which is around 50mb, you need to make sure that there is atleast 250mb of free internal storage(would be much more in case of the facebook app...coz on installing it takes up around 150mb)
In case you have enough memory...move the app to external memory once installed and then open the app


YouTube link preview not showing up in WhatsApp

The best solution I could find was to adapt the URL copied in the share button

This is basically substituting youtu.be with youtube.com/embed leaving the last part (in this video, bDPczGUovzE) untouched.
So now we can see already a preview before even sending

Once sending it we'll see

Edit
As of today this issue is already fixed and Beta users of WhatsApp can already take advantage of it.

Android 2.3.5 unlock screen activated unexpectedly

I don't know why this happens, but you may be able to combat the problem with Proximity AutoLock.  If the phone's screen is somehow turned on, the proximity sensor should tell the phone to turn its screen off right away.  Now, this works when the power button gets pressed; I would think it would also work when other events turn the screen on, but I'm not completely sure.
