Can someone explain how slots work when overclocking? I have been trying to use the DX/D2 Overclocker app on a rooted Droid X and I have been having a hard time finding good sources of information about overclocking.  The app provides preset profiles for stock settings and other overclock speeds, but not much information besides that.  For instance, here are settings for the stock Droid X:

Slot 1: 400000 / 27
Slot 2: 700000 / 38
Slot 3: 900000 / 50
Slot 4: 1100000 / 56

As I have come to understand, slot 1 refers to the minimum speed and slot 4 is the max speed.  I assume that the other slots are for levels in between the min and max, but what are these sections for?  How can I figure out how to set these slots in order to get better performance out of the device?

Each slot refers to a specific clock speed that your phone's kernel allows (in your case, 400mhz to 1.1 ghz). Therefore, these clock speeds can vary between different kernels (different values or even more slots).  In the case of the Droid X or Droid 2, you are stuck with the stock kernel due to the locked bootloader.

I'm more familiar with using SetCPU.  SetCPU lets you manually choose which clock speeds you want your phone to run at.  You choose a min clock speed, a max clock speed, and how you want it to scale (ondemand, performance, etc.).  You can also setup profiles with SetCPU that allows your phone to run at certain clock speeds under certain conditions.  For example, you would want to lower you clock speed when the phone's screen is turned off.  You may also want to lower the clock speed when your battery is below a certain battery % to try and pro long battery life as long as possible.

If you're wanting to conserve more power, set the clock min and max clock speeds low.  If you're wanting better performance, then set them higher.  On my phone (Droid 1), I use an undervolted kernel and typically run at a 250mhz min, 600 mhz max clock speed to conserve battery.

If my answer doesn't fully answer your questions, leave a comment and I'll try to help you further.


How to flash custom ROM together with modem and bootloader without odin or heimdal? I want to flash the "newest" SimplRom (v5F) on a Galaxy Note 4 and the instructions say I need to also flash the modem and bootloader firmware at the same time.

Now I have three files: BL_N910FXXU1COI3.tar.md5, CP_modemCOI3.tar.md5 and SimpLite_v5.zip but I'm not sure how to flash them.

Most instructions tell me to use Odin, some describe the procedure using Heimdall. Odin is not an option for me (no Windows) and Heimdall seems to change it's user interface every now and then, so the instructions don't apply.

To make it short: is there a way to just use TWRP  or dd (this worked for TWRP) to flash the files? I've found a lot of instructions but since there are so many different file types, recovery roms, devices, tools etc. out none of the instructions seem to apply for me..

Do I need a PIT file for the dd approach?

Important note: Hey guys, thanks for the upvotes but this answer turned out  to not work at all.

The steps below don't break anything and this is why I thought I flashed modem/bootloader. You can use dd to make backups of the partitions below by swapping of/if but modem/bootloader won't be modified by the code I've posted..

In the end I had to fiddle with heimdall and boot the phone in download mode to actually flash the partitions.

Original answer:

In case anyone else wants to flash Bootloader/Modem and heimdall/fastboot/odin is not an option - this worked for me:

Extract/copy the files you need somewhere on your phone - e.g. with adb push ./bl_modem/ /mnt/extSdCard/, start a su-shell:

adb shell
> su
> cd /mnt/extSdCard/bl_modem/

then just flash the files with dd:

> dd if=NON-HLOS.bin  of=/dev/block/mmcblk0p1
> dd if=modem.bin     of=/dev/block/mmcblk0p2
> dd if=sbl1.mbn      of=/dev/block/mmcblk0p3
> dd if=sdi.mbn       of=/dev/block/mmcblk0p5
> dd if=aboot.mbn     of=/dev/block/mmcblk0p7
> dd if=rpm.mbn       of=/dev/block/mmcblk0p8
> dd if=tz.mbn        of=/dev/block/mmcblk0p9

Important: the provided block device names only apply to Note4/N910F. Have a look at the links at /dev/block/platform/msm_sdcc.1/by-name/ to find out yours.

I double checked these names by first making a copy with dd and comparing sizes. The sizes won't be equal to the sizes of the files you're going to flash but they should be about similar size.


How to properly close running apps while avast! Mobile Security is installed/ running in the background? I've just installed avast! Mobile Security on my Samsung Galaxy SIII. Runs perfect so far, but I can't close my programs running in the background anymore. I used to do this by pressing the button below in the middle long - now this does not open up anything.

How can I close them now? If I don't: will this have a negative influence on my battery (faster emptying it)?

Many thanks and BR

I don't know what Avast is doing there (I do not use any AntiVirus app, as I see no benefit from it). But as to the second part of your question: You should not really need to explicitly close an app, as Android normally does a good job taking care itself. For details, please see the Process LifeCycle description as described on the Android developers page -- for a short look, see this graphical description:

Image taken from BottomLessInc Blog

You can see three arrows going from the "Paused" state: Directly to "destroyed" (explicitly "closed" the app), or via "Stopped" -- and back to "Running". In simple words: When you "leave" the app in the background and afterwards return to it, it goes back to "Running". If you don't return, and the system decides it is no longer needed. "Destroyed" you can take as "ended and cleared from memory", "Paused" as a kind of "Stand-By for immediate access", and "Stopped" like "Ready to be cleaned up".

Again, this is a very simplified explanation. If you need more details, the "big keyword" for this is "OOM Killer" (OOM = Out Of Memory), which is the part of the system taking care you won't run out of ressources. See e.g. this blog article for more details.


How do I get my stock ringtones back? I have a Droid X, and I've been having issues with my music lately.  I finally deleted the Albums, Music, and Playlists directories from my SD Card, and used SDRescan to get the media library to update.  That did the trick for the music, but now my stock ringtones have disappeared.  Were they on the SD card?

Why did they disappear, and how can I get them back?  My phone isn't rooted.

I tried rebooting when I was seeing the problem, and that didn't help.  I wound up setting two songs from my SD card as the ringtone and notification sounds, and that didn't help either.  My phone crashed hard today while downloading an app, and I had to pull the battery to restart it.  After that, the original choices reappeared.  Go figure.


Streaming Android screen to YouTube, Twitch etc I have Lenovo Yoga Book, which I would like to use for drawing - it has a drawing tablet with a stylus.
I would like to use it to draw on Slack meetings. However, screen sharing does not work on Android version of Slack. So I was thinking I could stream the screen to YouTube and send my colleagues a link.

I have tried Mobizen, but that gives me "Stream Error: 901".
I have tried Twitch app but that's only for viewing.

Does anyone have some working solution?
Android 7.1.1.

I figured out. The Omlet Arcade
app works like a charm.
It even supports internal audio streaming, but only from Android 10 which supports it itself.

In case anyone has the same use case as me - drawing - then the app I use for collaborative drawing is Aggie.io, and for stylus-on-tablet drawing I use Lenovo NoteSaver, which one of the few apps which supports the drawing pad.


Why does the in-call volume change on its own on my Samsung Galaxy S3? I have a Samsung Galaxy S3 (SCH-I535) running Android 4.4.2 and I'm having an extremely annoying issue: Whenever I make or receive a call, if I adjust the in-call volume to the desired level (usually somewhere between 80% - 100% if I am in a noisy place) then during the call, the call volume will suddenly drop to roughly 25% - 35%

This happens repeatedly during a call. I am not using a headset of any kind: I am simply holding the phone up to my ear. I am positive that I am not pressing any buttons on the side of the phone, and I press the lock button to turn the screen off before holding the phone up to my face, so I'm sure I'm not triggering any on-screen functions with my cheek/ear.

This makes it doubly annoying because the volume buttons don't appear to work reliably when the phone is in this state. So after a few minutes at the desired volume, suddenly I can't hear he other party and I need to ask them to please wait, bring the phone away from my face, unlock the screen, adjust the volume back to maximum using the volume buttons (ever time I see the volume slider has dropped from where I last had it set) lock the screen again and then resume my call.

This will happen repeatedly, every few minutes while on a call.

I have the stock Verizon/Samsumg OS, phone is not rooted, and I can't find any setting which might be causing this. I don't have any custom volume adjustment apps installed. Looking for any assistance! Why does the in-call volume drop on it's own on my Samsung Galaxy S3?

The problem was caused by an app that I installed for allowing the company I work for to page me. This proprietary app had a bug that caused it to drop the in-call volume during a call; Updating the app fixed the problem.


Can I install Google Edition Android on an HTC One X+? Recently, the HTC One Google Edition has been released which has Google Android 4.2.2. I'm currently using an HTC One X+ and I want to install Google's Android on my mobile.
I've found some links on how to install vanilla Android on the HTC One:

Redmond Pie
XDA

I'm willing to install that on my mobile. Can I do that, and if so, are there any cons to doing that?

Is it possible to install vanilla Android on my phone so that every time the Android is updated, I get the updates directly from Google?

A ROM for the HTC One won't work on the HTC One X+. Despite the name similarity, they're completely different phones, with different hardware inside. (The HTC One X+ has a Tegra 3 SoC, while the HTC One has a Snapdragon.)

If you want to install a "stock Android" ROM on this phone, you'll have to find one first, and as there isn't a Google Play Edition for the One X+, this is very unlikely to exist. You might be best with a custom ROM that doesn't have many customizations. Generally, custom ROMs don't update over the air: you need to reflash whenever you want to upgrade to the latest version.


my internal memory is empty but cant add new apps Not enough storage when loading apps to my phone why is this and my internal memory is empty, also new 4gb memory card is brand new.

Open settings>storage>miscellaneous and delete all the files from here
Also delete cached data(by touching it)It happened with me too but now every thing is fine I found a file named 0 in miscellaneous and on deleting it my phone started working properly


Remove Unlock Pattern in Motorola Razr i? I bought a Motorola Razr i in the web but It turns out that the phone has an unlock pattern and now I can't contact the seller. I have read some tutorials of the web talking about the "Hard Reset" which consist in something like this:

http://www.smartmobilephonesolutions.com/content/how-to-hard-reset-an-android-phone

When I try to do it I never see the Menu that I souposed to.

I really dont know If im doing well the process so I need someone to help me with specific instrucions of how to do this or with another solution.

Thanks.

Just tried it on my Motorola Razr i (4.1.2 Retail en GB):
To get into fastboot menu.

Turn off device.
Hold "Down Volume Button" (for a few seconds) and
    then "Power Button"
When phone vibrates/Motorola logo shows up/Green light goes off
    release "Power Button" but continue to hold "Down Volume Button"
Device will enter fastboot menu.

It did take a few tries to get the timing right.


Reinstalling TWRP via Odin on Android 4.1, failed after "SetupConnection" I recently installed TWRP recovery into a Samsung Galaxy Note 10.1 GT-N8013 tablet running Android 4.1.1 via Odin. I wanted to install a custom ROM, in this case LineageOS. Unfortunately, I installed TWRP with the check box "Auto Reboot" ticked, this meant I could not boot the tablet into TWRP recovery mode; instead it booted with the default Android System Recovery.

I then read this question which provided the solution to this issue.

What I had to do was reinstall the same TWRP TAR file in the same method but with the aforementioned check box unticked. I employed the same methods but what it returned was:

<ID:0/003> Added!!
<ID:0/003> Odin engine v(ID:3.1203)..
<ID:0/003> File analysis..
<ID:0/003> SetupConnection..

5 to 10 minutes later...

<ID:0/003> Complete(Write) operation failed.
<OSM> All threads completed. (succeed 0 / failed 1)

I tried using a different TWRP TAR file but I gave me the same result.

How else should I reinstall TWRP and how should I install it correctly?

Using the correct version of TWRP solved the issue. In this case, it was twrp-2.8.6.0-gt-n8013.tar.

In my previous attempts, I had used the incorrect versions of TWRP for my specific device: twrp-2.8.6.0-p4notewifi.tar and twrp-3.0.2-0-lt03wifiue.img.tar.


Polaris Office cannot set Date Format to UK how can we change the input & displaying of dates in Polaris Office to UK format?

The devices are set in Settings/System/Date and Time/Select date format to UK style (dd/mm/yyyy).

The default within Polaris seems to be yyyy/mm/dd. Other android users wrongly think this is UK format.

You can change the date format of cells to be any of the following:

yyyy/mm/dd (default)
mm/dd/yyyy (US format)
mm/dd
dd-month-yy
dd-month
month-yy
month-yy
month dd, yyyy
dd month yyyy (almost UK format)

Ideally we need the correct UK date format dd/mm/yy or dd/mm/yyyy as this is already in our source files. We cannot change this (only the format of the cells) as users will be working on files generated from MySQL in MS Access and outputted to .xlsx

This seems an oversight on Polaris part, but I don't see much 'chatter' about it around the web, so should we notify Polaris of this?

Yes. If an app doesn't work the way you want, or you can't work out how to make it do what you want, it's always appropriate to contact the developer.

You can do this via Google Play: every app has to have an email address or phone number for support, which you can find on that app's page. Many apps also have a "support" or "feedback" option inside the app too.

Even if the answer is that there's no way to do this and they don't intend to add it, at least you know that from the horse's mouth, and of course if they get enough requests they may change their mind and add it. And going the other way, even if there was already a really simple way to do it, and they just tell you how to do it, it lets them know that they need to make it easier to find in future.


Why my Nexus 4 keeps blinking the notification LED? The notification LED in my device is always blinking. There's nothing in the notification area and it keeps blinking.
Sometimes its a dark blue / violet and sometimes it changes to a white light.

I Don't understand if this is an expected or unexpected behavior. I presume the notification light should be related to the notification area and should stop when it is cleaned.

I read here LED wont turn off that I should try reseting it. I'll try it if works I post here again.

If your device is no more in an area where it can reach GSM network, the notification LED will blink (in white if you installed LightFlow).

Still with LightFlow installed, the dark blie/violet blinking is the notification of a new SMS.


Best codec to use for RockPlayer? What is the best codec should I use in convertion a movie from huge HD/BRay for watching it on Android's RockPlayer?

Also what are the optimal properties should I specify for better performance+quality? (bits-per-second, resolution, audio quality, etc...)

You will get the best results using the built-in media player/decoder (called "system player" in RockPlayer, iirc) because it supports hardware decoding. For a list of supported containers and codecs see here: http://developer.android.com/guide/appendix/media-formats.html

I would recommend H264/AAC inside a MP4 container, like the website recommends, but with your device's native resolution (and a higher video bitrate, if necessary).

Though RockPlayer's ffmpeg decoder is able to play almost every media codec, the results will be quite poor (only software decoding).


.zip folder not showing up on TWRP I have a boot animation .zip file under \system\media on my phone, but the media folder isn't showing up under system when in TWRP. Why can't I see the .zip file in TWRP when it's visible in Root Explorer?

I figured out what the problem was - "System" under "Mount" in TWRP was unchecked. After checking that, the folders under system appeared.


Are home screen icons restored after reinstalling a Nexus device? I reinstalled my Nexus 5 from scratch, erasing everything.

I had Google account sync on. After signing in, all my apps came back in a matter of minutes.

But home screen icons, widgets, folders did not come back, even after a couple of hours. Should I keep waiting for them? Is there any hope? My homescreen background appeared out of nowhere an hour later. Maybe that's a sign?

There is absolutely no progress of restore operation whatsoever unlike iOS devices, which show ghosted icons for apps to be restored. When is it over? When can I assume what's gone is gone?

I will stop waiting and start working on hours of drag'n'drop sweetness if it doesn't support restoring of home screen icons. It's ridiculous but not more than staring at an empty home screen and praying. Is there any place that I can debug this issue? Or re-trigger, force, whatever?

Assuming you are using the stock Google launcher...

In my experience, no, they are not restored automatically. Only the wallpaper is restored.

That being said, if you had made a backup using Titanium Backup or something similar this would be able to restore your home screen design. Just reinstall your apps first and then restore the backup.


Connect to internet via internet cafe PC when no wi-fi or 3G is available? We are developing an Android data-entry application for use in places with very limited connectivity.  We'll be using old/discarded Android devices in areas outside towns in Kenya, Uganda, etc. where there is no wi-fi; the devices themselves are not signed to a phone service.  Users collect data in the field & return home, where typically internet access is available only via shared PCs at internet cafes.

I'm wondering if there is an easy way to connect an Android phone to a PC via the USB cable such that it shares the PC's internet connection for outbound connections?  ie. reverse tethering...  which seems to be a common topic, but all of the solutions seem to involve installing software on the PC, which I'm not sure would work at a cafe.  Is there "an app for that"?

I can provide more details if it helps find a solution!  Thanks

No; a device-side app can't force the PC to share its internet connection.

One option might be to connect the device and mount the storage to the PC, so the data could be uploaded to a website or emailed.  This has its own issues -- depending on the PC OS and the particular phone, drivers might be needed -- but it should work in some cases.


Where did my 16gb of memory go? I am not educated on Android enough to figure this out on my own. My problem began New Year's Eve with error messages saying device memory was full. My Galaxy S2 Skyrocket began to lag and wouldn't allow me to access photos or contacts. It would freeze. I'd remove the battery when it would get stuck restarting. I looked in "Storage" and found that the device's memory is only 1.97gb. Then I noticed that there was 11.26gb going to USB storage. Where did my memory go? I was told by a tech friend that I may have a "hidden partition." I appreciated a very basic, non-technical explanation on how to fix this. Thanks.

I had a similar issue where I could not figure out what was taking up my phone's storage.
I used an app called DiskUsage to visualise the issue and find the folder causing the problem.


I cannot backup the data between PC and ES file in bluestacks, windows folder shows question mark , not sure what that is I can go to the sharefolder on my PC, but not in the ESfile of bluestacks

I finally found the solution on another site.  In Bluestacks under My Apps click on Settings, then Storage then Explore and from there you can access all the folders.


Possible to disable LG Cliptray? My LG G2 (and I assume other LG phones) have a "Cliptray" which replaces the clipboard with one where you can access the history. I'd like to remove this function as 1Password cannot remove copied passwords after a set time.

Phone is rooted, if that helps.

Since the device is rooted, here's a way of disabling Clip Tray:

Go into Clip Tray and delete all entries.
In the file /system/etc/permissions/com.lge.software.cliptray.xml, change this line

&lt;feature name="com.lge.software.cliptray"/&gt;

to

&lt;!-- &lt;feature name="com.lge.software.cliptray"/&gt; --&gt;

This will put the feature in comment, and will not grant permission for this feature.
Reboot the device.

Note: You might still see the option Paste, Cliptray in your stock LG keyboard, which will not work after this modification but cannot be hidden or removed. A way to work around that is to use an alternate keyboard, like Google Keyboard.


Can't access my old files after switching ROM from AOKP to CM, even though they're still there Initially I thought this was a problem with Google Play / Apollo, but I realize now that when I plug in my phone via USB, I can't see any of the many, many folders and files present on /sdcard that I could see previously.

If I copy a "new" mp3 onto my Galaxy Nexus, it's recognized just fine by both Google Play and Apollo. However, none of my old mp3s are recognized. They were placed in /sdcard/Music, a folder that I cannot see when I plug in my phone, only from the file manager running on the phone. The issue persists if I move an "old" mp3 from my music folder out into the sdcard root, it's still not recognized. This makes me think this might be permission related, but the file manager says that all files are readable and writable.

I've tried running "fix permissions" in both ROM manager and the CWM recovery, but it makes no difference. Any idea what has happened, and how to fix it so that I can use all my old files again? :)

edit If it's any help, I just ran ls -al in a terminal emulator and I can't see any difference at all between folders I can and cannot see. Example: I can see /sdcard/media just fine, because I created that folder from Explorer in Windows. Music in that directory works. I cannot see /sdcard/music. Here's the permissions:

drwxrwxr-x root sdcard_rw 2012-09-18 media
drwxrwxr-x root sdcard_rw 2012-09-16 music

This is a bit confusing.

edit2 When I try pulling and pushing a file with adb like so:

adb pull file.tar
adb push file.tar file2.tar

I get

failed to copy 'file.tar' to 'file2.tar': Read-only file system

As bk201doesntexist on the XDA forums pointed out, this is because you have to use an absolute path. However, when I do adb push file.tar /sdcard/file.tar the file gets transferred, shows up when i run ls, but it's invisible in the "Galaxy Nexus" unit in My Computer in Windows.

tl;dr When I push files with adb push they get transferred but don't show up in the "Galaxy Nexus" unit in My Computer. "Old" files from before ROM-switching do not show up. New files that I put in now work fine.

A few things that will do you good before you start resolving this issue.

This issue has been around since CM 9 and has been inherited by CM 10.
While ROM Manager (and not CWM) was the culprit some time ago, the issue has since been resolved by them.
The .nomedia file you are looking for should be inside /sdcard/Android/data. It may not be there but can't hurt to look for it.
Have a good file manager with root access installed and have it set up to search for hidden files. I recommend Root Explorer.

Okay, enough info. Let's get cracking. Follow this and let me know if it resolved your issue. Follow everything to the T. Do not leapfrog over steps or try to do anything else before you have gone through the entire process. All the best!


Is it possible to export the S-Health data from a Samsung S6 into a usable data format? Is it possible to export the S-Health data from a Samsung S6 into a usable data format?

For example, to CSV or similar, so I can import into Excel

There are few ways that you can export it.
it won't work on Settings>About Device and confirm you have an SM-G900?

1:Go to developer.samsung.com/health and download the Samsung Digital Health SDK
Extract the files and read the ProgrammingGuide_SHealthService.pdf to find out how to put S Health into "Developer Mode"
From the Health Data / tools install the DataViewer-1.2.0.apk to get the data viewing app which can export to CSV.
Once its all set up reboot the phone and all exports fine.

2:You need to install dataviewer.apk to your phone and not your computer. Make sure your turn on the developer mode in S Heath.
Go to S Health-more settings-about S health. Right above "check for updates" tap 10 times on the version. If it works then it will turn to developer
mode.
Go to your web browser on your phone and go to developer samsung com/health and download. You will need to extract the zip file once downloaded find the dataviewer.apk and install it. Reboot your phone.

Read the programming guide because your need to turn on the permission to sync the data between the dataviewer and S Health for each item you want to view.

To Export the data, go to the main screen of dataviewer and on more is where you export the data. Once you export the data, you need to use a file manager like file commander to find the file and email it to yourself. It should be under the health data folder. It is located under storage/emulated/oN health/com.samsung.health.blood pressure.201601310420.csv for example

Nexus 5 stuck on black screen Nexus 5 showing black screen

1.Can access fastboot mode

2.Cannot access recovery mode from fastboot : shows google logo and black screen (no inverted android)

3.When selecting Start from fastboot : only google logo appears and then black screen (not even the marshmallow boot animation)

Things Tried :

1.Phone was able to ring from android device manager. Tried erase from there. No response

2.Tried flashing the stock rom still no response.

What might be the issue ? Is the internal memory corrupted ?

UPDATE

The phone boots up able to hear screen shot sound but still black screen

UPDATE 2

The phone had hardware issue, the flex cable was damaged. Replaced the flex cable and phone is working again.

Since Recovery won't start up, you can clear the cache by powering off your phone and holding down Power + Volume Down for 20-30 seconds.  Then you will be able to enter recovery once you restart where you should clear the Dalvik cache and cache again.  I had the same problem and this worked for me.


Touching multiple web elements simultaneously brings out area with magnification for clarification of intended target – name of feature? When you touch multiple web elements simultaneously, perhaps due to the widgets being too small, and/or too close together, the area around where you touched pops out, giving you a magnified view of that area. I suppose this is so that you can clarify which interface control that you intended to touch.

Does anyone happen to know what this feature is called?

Eye tracking interfaces have a similar feature called “Gaze Clarification” for selecting small targets. As you look at your intended target, a portion of the screen that includes that target becomes magnified, and the zoom level keeps increasing and increasing as you home in on your desired spot.

Thanks.

It's enable-link-disambiguation-popup.

  It’s a handy feature and is now available in Chrome OS.

  Since this is experimental, you’ll have to enable it, which is an easy process.

  Simply type chrome://flags in the Chrome OS browser and find the enable-link-disambiguation-popup option.

  Enable it and restart the browser to activate the feature.

how can I auto connect to open wifi? I have Galaxy Note2.

Is there a way to tell it to auto connect to open wifi when availble?

Whitout me needing to scan and choose open wifi?

In your devices settings (under Settings → WiFi or Settings → Wireless & Networks → WiFi, depending on your Android version / ROM) you should find a check-box to enable notifications for "open networks". If you enable that (and, of course, have WiFi enabled), Android will always scan for networks in the background (which it does anyway with WiFi enabled) and display a notification in the notification-bar to inform you whenever an "open network" was detected.

This does not automatically connect you to that network, for security reasons. Otherwise hackers would have an easy job to lurk you into their honey-pot, hack your device, and leave you - virtually - "naked". It's not a really good idea to simply connect to any open network around. Many background connections are not secured, or at least not well secured, so it would be easy to sniff your passwords or personal data transmitted (same for your "manual connections" via e.g. the browser). So pick your "open networks" carefully.

However: once you manually connected a network, Android will remember that -- and connect you automatically the next time it is in reach. Until you go and remove its configuration manually from the settings.

There are also apps available on the Playstore helping you in this context. While Android's default scanner shows networks using a "captive login" as open as others not using it, they even differentiate. A good example for those is e.g. WeFi Pro (at least it did show these differences in the past -- it's some time ago when I used it last).


how does an android rom decide the amount of phone memory? I used to mod symbian roms, and would like to know if it is possible in android to allocate extra internal storage memory, by removing unneeded apps, as packed by OEMs.

[NOOB ALERT]

if I manage to find a custom ROM that is smaller in size, does it mean I get more free memory?

On an Android device, the internal storage is split into multiple partitions. The data from the custom ROM is stored on one partition, and the apps and user data on another. (Generally there are a few other partitions as well.) Because of this, installing a smaller custom ROM doesn't directly give you more free space for data, because they're on a different partition. But if you can make a smaller custom ROM, it allows you to repartition the storage to allocate more space to user data.

Repartitioning the storage is quite risky, as you have to know exactly how large the custom ROM is going to be. If the system partition is too small for the ROM, it will go wrong when or after you install it.

I believe it's more common to simply add some useful apps to the custom ROM, to make it up to a similar size as the stock ROM. This way, you can avoid installing some large apps in the userdata partition, giving you more space without repartitioning. Since updates to pre-installed apps get installed in the userdata partition, not the system partition, even including up-to-date versions of those apps in the custom ROM saves space.


How do I send an SMS to a contact that only has an e-mail address? I can start a conversation in Google Messages to an e-mail address.  When I send the message, it appears to go through an SMS to e-mail gateway, and I (or whoever owns that e-mail address) can in fact reply to the e-mail and it gets routed back through the gateway and I receive an SMS.

This all works well and good, but the e-mail address is random letters and numbers and I want a nice description instead of that.  So I created a contact for the address.  However, now I can't send a message because Messages doesn't find the name when I search for it.  Oddly enough, if I happen to remember the entire e-mail address and type it in up to the "@" character, suddenly it "happens" to remember that there is a contact with that name and lets me select it.  However, this is pretty much useless when I have to remember a 12+ character string of random numbers and letters to get an auto-complete!

How do I get the contact to show up to send an SMS when it is only an e-mail address?  I have tried editing the contact and pasting the e-mail address as a phone number, but it strips out all the non-numeric characters this way.

I just tested the issue with a few different messaging apps, and I came to the conclusion that the app was simply not made to do that. In both Google messages and textra, I had the issue you describe, but as soon as I tried it in Samsung's messaging app it worked perfectly. As soon as I started typing the name, it gave me the email address as an option.

That's why I conclude that Google messages was strangely not made to do what you are looking for.

As a workaround, I suggest that you text the person once, and then every time you want to text them again, instead of initiating a new message, simply press on the search icon on the top right of the screen and type in the name of the contact, press on the contact, and you have achieved the same thing as you wanted with ease.

'Google Play Services is not working' i recently flashed my Samsung Galaxy S4 with Resurrection Remix rom.My phone now doesnt support any of the official Google apps.Whenever i open any such app, it says that 'Google Play Services is not working'

With some custom roms, the default Google play suite won't work. Check too see if anyone has released a Google play package for that rom.


Nexus 4 bricked by OTA upgrade In early august, both my nexus 4 and my nexus 7 got the OTA upgrade. The nexus 7 one worked without any problems. The one for my phone actually bricked my phone.

First it was stuck on the X-logo screen. I reflashed 4.2.2 and suddenly the phone had problems it never had before: random shutdowns, sudden locking of the SIM card, not booting unless plugged in.

I also did all the wipes and factory resets Play support told me to do, and a factory reset and everything. I even replaced my SIM card and flashed 4.2.0 and it still has the same problems.

I found a way to get 4.3 to get beyond the X screen, by flashing the radio back to an older version, but the above problems persist.

Is there anything that isn't overwritten when you reflash an older version? (I'm thinking drivers or something like that) If so, what could it be? And how can I get them back to an older version?

Since I voided my warranty (screen was broken and repaired by third party), I'm wondering if I can hold Google (or at least Android) responsible for breaking my phone...

TIA

If you've wiped everything you have probably wiped the system partition meaning there is nothing to boot up to. Try following the steps here to install a factory image which will wipe your device and completely re-install everything.

If this doesn't work then it is likely that there is a hardware issue, which due to you having the screen replaced is unlikely to be covered under warranty (nor will Google/LG take responsibility for it)


Is this Kindle Store App Legit or Bootleg? This question is inspired by the answer I received to this question: What is This Strange Symbol When I Try to Play Youtube on Kindle?
User @Banal Vulgarian reports that he has the same problem as I do in Silk Browser, but a specialized Youtube app works. I downloaded a specialized Youtube app and experienced the same success.
But I am suspicious of this app. Is this a legit app published by Google/Youtube,or is it sort of a "bootleg" app developed outside of Google's supervision which may be risky to my device?
Here is the app info:
Here you see the app in the Kindle store search results, with a non-standard Youtube logo (minus!), it has the best reviews of all results (plus!), and the most reviews of all results (plus!). Inexplicably it is the third result rather than the first result (minus!)

I'm looking at the one right in the middle with a blue logo (unusual for Youtube) but it says the publisher is Youtube.com
So I would assume that Kindle Store would sort of vet the names of publishers to make sure they are not impersonating a major company, right? But now look when I click on the contact info for the developer of this somewhat questionable app:

That email address looks a bit sketchy to me. Like a Youtube impersonator, to be honest.
Is this app officially sanctioned by Youtube? If not, what are the risks to me by having it on my Kindle?

To my knowledge, the only "official" Google apps are on Fire TV:
https://blog.google/products/chromecast/prime-video-chromecast-android-tv-youtube-fire-tv/
https://techcrunch.com/2020/07/09/youtube-kids-app-is-now-available-on-amazon-fire-tv/
And only consist of YouTube and YouTube for Kids.
I believe these are the apps referenced above:
https://www.amazon.com/s?rh=n%3A2350149011%2Cp_4%3AGoogle+LLC
Everything else is a third-party wrapper/interface.
As for the blue YouTube app, here is a 5 year old reference in a different forum. It may be that as long as the app is just a web browser wrapping the YouTube site (and showing ads), Google/YouTube will look the other way.


Whatsapp sync issue in Google Nexus 5 its not deleting the contact I have Google Nexus 5. My Whatsapp contacts are not deleting.

When I am trying to delete the contact from People (Contact App) it shows the error message
"You can't delete contacts from read-only accounts, but you can hide them in your contacts lists"

I deleted the contacts from my Google account but I am able to see those contacts in Whatsapp.

you might be having merged contact which you are trying to delete. To delete the whatsapp from the contact, you would have to delete the contact from phone list and then delete the contact from whatsapp. Obvisouly, you and again save the numbers in the contact list.


Will new Play Store minsdk restrictions prevent my phone from accessing new apps? I was reading an article that states by Nov. 2018, all new apps and new updates for apps on the play store will need to target minsdk level 26, which corresponds to Android 8.0.

Does this mean that my Android 7.0 device will not be able to download and install
new and updated apps on the play store after Nov 2018?

No, that requirement is the target SDK level not the minimum.

  Target API level is different from minimum API level. As the name implies, minimum API level is used to declare the lowest version of Android an app supports. The target API level is technically defined as the version of the operating system an app was tested to work with; but in more practical terms, it's used to define a set of behaviors an app expects from the operating system. For example, an app can target API 26 (Android 8.1) while having a minimum API of 14 (Android 4.0).

How to prevent apps from using my SD for its data? So, as you all know, even though they are they're installed in internal app memory, some apps tend to store some of its data in internal SD and some in external SD card. (To be more precise, in "/sdcard/Android/data/" and "/extSdCard/Android/data/" folder, respectively.)

Now, I was wondering if there was any way to prevent this, so that they store their data only in the app's private folder (in "/data/data/app-package/")? Or at least prevent writing data into the external SD card and just use internal SD for the purpose?

Info:
- Model: Samsung s3
- OS: Android 4.4 stock ROM (rooted)

Since the device is rooted you can install XPrivacy from Play Store. For this app to work you need to install Xposed Framework. Once this framework is installed, you'll have to enable XPrivacy's  module in Xposed framework which will require a reboot.

Once XPrivacy is installed and device rebooted, launch the app and tap any app icon amongst the list of apps icons(say Facebook app icon).
Scroll down to Storage and tap it to list permissions inside it.
Two entries there requires our attention:

getExternalStorageState -- Returns the current state of the primary "external" storage device.
sdcard (aka [(READ/WRITE/ACCESS_ALL)_EXTERNAL_STORAGE]) -- Allows an application to read/write from and into external storage.

Now that it is obvious from the context I mentioned around these two entries, you can go ahead restricting them for the apps you desire.

Note that there could be repercussions for restricting them, and the obvious would be the app failing to launch or crashing intermittently. It is advised to take a nandroid backup as well as an app backup.

XPrivacy allows et al.:

Creating a template of permissions which can be applied on apps individually rather than selecting the permissions by going into every app individually. The pro version allows applying this template on multiple apps simultaneously.
Restrict on Demand feature which will seek user's discretion every time a selected app is launched.
Automatic default template implementation on any new user installed app.

About XPrivacy

  Privacy can prevent applications from leaking privacy sensitive data by restricting the categories of data an application can access. XPrivacy feeds applications fake data or no data at all. It can restrict several data categories, such as contacts or location. For example, if you restrict an application's access to contacts, that application will receive an empty contacts list. Similarly, restricting an application's access to your location will send a fake location to that application.

  XPrivacy doesn't revoke or block permissions from an application, so most applications will continue to work as before and won't force close (crash).

About Xposed Framework

  Xposed is a framework for modules that can change the behavior of the system and apps without touching any APKs. That's great because it means that modules can work for different versions and even ROMs without any changes (as long as the original code was not changed too much). It's also easy to undo. As all changes are done in the memory, you just need to deactivate the module and reboot to get your original system back. There are many other advantages, but here is just one more: Multiple modules can do changes to the same part of the system or app. With modified APKs, you to decide for one. No way to combine them, unless the author builds multiple APKs with different combinations.


Face unlock and sun glasses I'm thinking about getting new glasses, the kind that get dark(like sun glasses) or clear depending on the amount of light they get so they are supposed to be dark in the outside and clear inside.

I think my actual question is: can you set up Android face unlock to work with "sun glasses"?

Yes, but this will probably be less secure than using your face...

i suggest using a password for maximum security !


Sort  contacts by different field (not first \ last name) Merging the gmail contacts with the phones address list has many advantages, but also one nagging problem.

While the gmail contacts contain full names, and in English, I want the display name in the dialer to be in Hebrew and I often use nicknames or first names only. Is there some workaround?

The easiest method I can think of is to use another field, such as nickname, for the Hebrew name. But this requires a contact manager that lists contacts by nickname, and not just first \ last name.

Dw contact manager supports this feature

how to keep internet connection active when in sleep mode android marshmallow' I noticed app background service not working that, when I would use my device after it had been sleeping, wifi wouldn't be connected using marshmallow .

Go to Settings, then click on WiFi. A somewhat similar screen will be shown:

Click on More.

Select "Keep WiFi on during sleep". If any option comes after that, choose "Keep always on during sleep". That's it.

This only happens with WiFi. Mobile data is never switched off by default unless you specifically ask the phone to do so by changing settings to conserve data.


Is the battery cycle count stored on the battery or the device? I downloaded an app Phone INFO which shows a number of stats, particularly "Battery Discharge Cycles". I want to know if this number is being retrieved from the battery (i.e. it's just the number of cycles for the current battery) or the phone (i.e. it's the sum of the cycles across all batteries the phone has contained). In other words, if I insert a brand new battery, should I expect the count to drop to zero?

Context: I have a Samsung S6, which doesn't allow easily changing the battery. I went to a phone repair shop to have the battery replaced. I left it there for the day and did not observe the process of replacement. Now I suspect that I was scammed and the battery has not been changed. I want to confront the shop and use the cycle count (which is still very high) as evidence, so I'm checking my understanding first.

It seems the issue is that when the battery is replaced, most mom and pop places don’t have the skill or equipment to go in the “root” to reset the counter. It’s akin to not resetting the change oil light on your car. The issue is that some cars use oil life to make other decisions on engine operation, so without resetting the light, performance isn’t fully restored because the computer thinks it’s still old oil and making its decisions based on that. Your battery life, auto shutdown, and battery life remaining display are kind of the same. I bet your phone goes to zero faster than you expect and shuts off, but after leaving it off for a while, you can cut it back on and it’ll show 20-30% or more battery. If so, the thing to do is to keep draining the battery without plugging it in, until after sitting the phone doesn’t even have the juice to try to start, then charge it up to 100, preferably on regular vs fast charge. The life monitor will adjust to the new high and low, and you should have better battery life performance. What’s happened is your phone is basing the full charge and dead capacity off your old battery still, and this process should force it to adapt to your new one.


How to delete search history from Settings app? In Android, it's possible to search for a specific setting by clicking the magnifying glass in the top right corner of the Settings app and typing. However, I haven't found a way to remove earlier search queries.

I have recently misspelled a word, and  it always pops up when I search for something else.

Is there a way to clear the search history, or, better, to remove a specific search?

Clearing the Settings App data will not reset any of your settings to their original state, but should clear the search history.

In the settings, navigate to your apps and find Settings and tap on Clear Data. The app should close and when opened back up, the search history should be cleared.


How can I change the temperature unit in Lollipop's lock screen? Today, Lollipop became available for my Samsung S4 and I upgraded. Since then, the lock screen shows the current temperature:

As you can see, it shows "61 °F". Since I am located in Continental Europe, I prefer Celsius.

How can I fix that? As you can see in the others screenshots (lock screen configuration), "Additional Information" is "On" and greyed out, and accessing the "lock screen widgets" menu item only lets me configure the personal message, nothing else.

I do use a third-party weather app (Weather & Clock Widget), but I don't think this is related, since (a) the third-party app does not contain a lock screen widget and (b) the app is set to Celsius.

I've found someone on the Internet with the same problem, but I haven't found a solution yet.

First, in order to enable/disable the widget altogether, go to

Settings > My Device > Lock Screen > Lock Screen Widgets > Clock or Personal Message

and select Clock. This activates the following menu:

Settings > My Device > Lock Screen > Additional Information

That enables you to select whether to display a weather and/or pedometer widget on the lock screen. On the weather widget description I read:

The data will be taken from the weather widget and shown while the device is connected to the network

So, obviously, the units etc come from the original weather widget that comes with lollipop. What I did to correct the units is:

Add the weather widget to a spot on the home screen. Enable your GPS, let it find our where you are and fetch weather data. Tap on that widget, and the first item on its settings is the units.

However: although the temperature on the lock screen weather widget appears in C, it says it's F (eg instead of 10C it reads 10F). Probably one of those loose ends that will be taken care of in the next updates.

Hope this helps. It took me ages to find out how it's done.


Can I, simultaneously, run two instances of the Facebook app? Can I, simultaneously, run two instances of the same Facebook app
(which is installed once in the system)?

I want to be active on two accounts (I also have iOS and Windows Phone devices if their support for multiple instances of an app is better than Android's. But my Android phone is my main phone, hence I prefer an Android solution.)

Also, can I get parallel notifications from both accounts (I don't need any chat messages, just the notifications from a specific Facebook group on my second account).

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)


S7 Edge: Internet randomly stops working until reboot My Samsung S7 Edge (Android 7.0) has lately developed the following problem: every once in a while, at seemingly random times, the internet stops working - in any app, and both on WiFi and on mobile. Connectivity is only back to normal when I restart the phone.

This occurs maybe once every 2 days or so, and is as you can imagine very disruptive. I've let it update the OS but even the most recent update did not fix (it may not even acknowledge) this bug.

Any ideas?

I had a similar issue with my s7 (non-edge) when I had data saver turned on.  Turning this off solved the issue for me.  If it is restricted to certain applications, you may be able to add them to the exception list and try.

The data saver setting is under settings -> Connections -> Data usage -> Data Saver.


Rooted phone bricked without CWM Hello~ I just wanted to ask whether my phone has a chance to be fixed or not. My bro just installed a chainfire 3d app on it and the next thing I know, my phone was bricked and stucked on the android logo.

My phone is rooted but I dont have clockwork mod, but I can still access the recovery mode. I dont have an external mmc though, Is there any way to fix it?

I tried ADB then in the recovery mode, I choosed install from adb etc. etc. then it will be detected on the pc using adb devices. but whenever I use other adb commands, it says error: closed.

I remember reflashing an old phone a long time ago using ODIN but  I can't remember how-to anymore. Am I able to do the same thing in my phone? That was a samsung pocket. My phone I am using now is a Cherry Mobile Thunder 2.0 / Android Jellybean

I also tried pressing Vol- + Power then it brings me to Factory mode. But only tests and celar mmc etc. no download mode. but if I press vol+ power then it is in the recovery mode.

Since this is getting inactive for so long and no one seems to know the solution. Then I guess I'll bring my phone to where I bought it and face the consequences of my actions HAHA! If they can't fix it, then no one can. LOL

Cheers, guise!


How do I restore my rooted Motorola Droid back to completely stock and unrooted? I'm thinking about unrooting and going back to completely stock, vanilla Android on my Droid.

How can I do this?

This website has a very good answer:
http://www.droidforums.net/forum/droid-hacks/13466-how-back-stock-no-su-no-busybox-etc.html

Seems to cover all your bases.

Essentially involves:

flashing the stock recovery and boot images to replace custom ones
then either

manually removing all the "root" bits, or
(option B in the post) flashing the official update.zip putting your phone back to stock!

Good luck :)


How can I back up files from LG's Browser? In anticipation of my phone dying soon, I've been backing up every file on it. I'm using an LG G Flex, and it comes with a generic browser. Browser came with a "save for offline reading" function, which I used to use regularly, until I found out that nowhere in the file manager can I view or access these saved webpages, which makes backup much harder.

Since then, I've been using a separate app to save new webpages, and to back up the old ones I've been individually saving every page to Capture Plus (the browser's full page screen capture function).

I'm now down to my last webpage, but Capture Plus tells me that there isn't enough memory when I try to capture it as a screenshot.

This doesn't mean that there isn't enough memory in the location I'm saving to, because I know there is, so what gives?

The saved webpage that I'm trying to back up is one that has been removed from the internet, so I can't just go back to the same website and download it again.

I could take about 3,000 screenshots of the page and later assemble them into one (it's a pretty long page), but if there's a way around that approach, I'd like to know about it.

LG's built-in backup is very good, alternatively you can use adb backup.

adb backup -all Now unlock your device and confirm the backup operation.
Unplug old phone plug in new phone, adb restore backup.ab
Now unlock your device and confirm the restore operation.


Links always open google first This just seems wrong. When I click a link in an email (gmail), or anywhere else on Android, it first loads a google page then opens the link. Like google is tracking every link I click. Seems inappropriate. Any way to disable it?

As this behavior occurs with every app on your system most likely the configuration of the "Default Application" for http and https links has been changed.

You can configure all default Applications in the Android Settings. The exact path to the Default Applications settings depends on your Android version and device vendor (some vendors modify the Settings menu).

For example on Android 7 you have to open the Apps section and then the gear icon in the top right corner. Select the Browser App and you can choose which app to use as web browser.

On Android 8 there is in Settings the entry Apps & Notifications -> Extended -> Default-Apps where you can configure the default Browser app for example.


No access to Android Market after loading Ice Cream Sandwich I followed the instructions on the source.android.com website to download, build, and install Android OS v4.0.3 on a Nexus S. Everything seemed fine, I could take pictures, access WiFi to surf the web, etc. The problem is that there is no Market app and I have been unable to install anything via the Market over the web. The apps I had on the phone prior to loading ICS all show as "installed" on the website but they will not sync with the device. Any time I try to install a new app, everything seems to go ok and then it says the download will begin shortly but it never does. I have tried many different things described on posts such as resetting to factory defaults, clearing cache, etc but nothing works. Does anyone know how I can load the Market app or somehow download apps from the Market to manually install?

If you built the image yourself then Google's proprietary apps would not have been included as they are not open source. The easiest way to get them is probably to just use the CyanogenMod9 gapps package, which can be downloaded here (top of the table). If you have a custom recovery image then you can simply install the .zip file from your recovery, otherwise you'll have to manually install each of the files in the .zip (they have a folder structure that mimics your device).

The reason why the web Market isn't working is because it tries to use C2DM to push the app to the device, but this requires the Market app to be installed on the device. You cannot download the .apk from the Market manually.


Replace audio cable with wireless solution I want audio from my Nexus 7 to play through my amplifier (without replacing it). I think this would be possible with the iPad/AppleTV combo.

I don't want to be locked to a specific app that only plays certain files etc, but more like being able to select another Audio Out destination. Also, I'd rather not use Bluetooth, since it needs to compress the audio.

You could probably say I want Miracast, but for audio.

Sorry, lots of demands. Is there a device/protocol to make this happen?

I can think of 2 ways you could do this.

Bluetooth audio adapter, like the Antec BXR100.  These are generally used for headphones, but should be able to simply connect into your amp.
-Pros : Simple, cheap
-Cons : Bluetooth, limited range, A2DP appears to have issues on Android 4.2, possibly non-optimal audio quality
DLNA renderer (mini computer (raspberry pi (Raspbmc maybe.  There's a topic on the use of raspbmc as a DLAN renderer here on their forums.) or similar perhaps), specialized unit (Like the (discontinued, though still findable if you don't mind buying used) Netgear MP100 series), or maybe a cheap Android device) attached to your amp, getting your audio pushed from one of the several DLNA server apps available for Android.  This is essentially the same as Apple's Airplay system, only a different, more open standard which will work with more manufacturers' devices.
-Pros : Almost as simple, will work anywhere you can get a wifi signal, possibly better audio quality than the bluetooth, could potentially be used to move video if you wanted to in the future if your chosen receiver has that capability.
-Cons : More complex, possibly expensive, new audio-only DLNA renderers seem to be rare nowadays.


Is there a stopwatch app that also records time of day timestamp? I've looked all over Google for a stopwatch app that records laps (which they all do) but also records a time of day timestamp. If it can't do the example below, at least record the initial start time of day (and I can figure out the rest).
i.e.

Start (10:09:00 am - I want to know I started at this time)
Lap 1 - 00:01:02 (10:10:02 am)
Lap 2 - 00:12:12 (10:22:14 am)

UltraChron StopWatch Lite. It doesn't time stamp each lap but does the start time.


Access chats from old deactivated phone number My sim card with my old number has been deactivated. A new user uses my old number. Does the user  have access to my old chats if he or she chooses Yes to back up old chats or storage?

Whatsapp backups are either stored locally (on you device), on your own Google Drive account if you are using Android or on iCloud if you're using an iPhone.

In order to restore a backup you must be using the same phone number and the same Google/Apple login, so you can rest assured that the new owner of your old number does not have access to your old backups.

If you want to be doubly sure and you use Android, you can log on to Google drive and find your Backups folder. In there you should see a file named "WhatsApp YourOldNumber backup", you can delete this if you want.

I don't own an iPhone but I imagine the iCloud backup would be stored in a similar fashion.


What does debug.sf.hw in build.prop mean? It is advised here and there to add debug.sf.hw=1 to build.prop.

They say that this "makes Android render GUI with GPU". This looks very suspicious because what does it debug then (and since when debug speeded up anything)?

So I'm just curious about what does this setting (property) actually means?

I believe what it stands for is "Debug SurfaceFlinger Hardware", and there's only one (that I know of) reference to it in the Android source code (in DisplayHardware.cpp):

// debug: disable h/w rendering
char property[PROPERTY_VALUE_MAX];
if (property_get("debug.sf.hw", property, NULL) > 0) {
    if (atoi(property) == 0) {
        ALOGW("H/W composition disabled");
        attribs[2] = EGL_CONFIG_CAVEAT;
        attribs[3] = EGL_SLOW_CONFIG;
    }
}

Or, in English terms, the system reads the value of the debug.sf.hw flag. If it has a value and that value is equal to zero it disables hardware compositing, otherwise it skips over that block of code.

I think there's something of a misconception in that the default should be to have hardware compositing enabled, but you can set debug.sf.hw=0 in order to disable it. So really it is a debug flag, but setting it to 1 (strictly speaking, any non-zero value) would explicitly cause compositing to remain enabled. As far as I know, though, the only time it should really have an impact is if the device's default value is 0 for whatever reason.


Google Now option "Contact recognition" is not visible on my HTC One (M7) I have a HTC One (M7) and just purchased an LG G Watch R. The combination is working fine, except for the fact that my contacts are not recognized when speaking via "OK, Google".

I wrote a mail to HTC, they told me it's an LG issue. I wrote a mail to LG, they tell me it's the fault of HTC. I have no idea anymore what to do.

In Google Now, going to Accounts & Privacy should have an option "Contact recognition", between items "Safesearch Filter" and "Search engine storage". I don't have this option.

Any idea what could be wrong?

Undo Android 4.0 (aka Ice Cream Sandwich) Full Disk Encryption Just upgraded my Nexus S to Android 4 aka Ice Cream Sandwich. Was looking through all the new features, and decided to enable encryption, which worked (and is working) just fine. Now I'm wondering if I can undo that and revert to an un-encrypted filesystem.

There does not seem to be an option in the settings area, and while I'm not fussed about doing a factory reset, I just wonder if I'm missing an obvious option somewhere. Can anyone help? Or even confirm that the factory reset is the only way out?

There should have been a warning when you begin the encryption that you had to agree to. The only way to unencrypt it is to perform a factory reset, thereby wiping your data partition completely.


how to take complete backup of my android device using adb I'm trying to take full backup using adb backup -all -f <path> and it took backup and stored in my PC.

When I try to restore it using adb restore <path> then it restores onto the target device.

ADB backup command is not taking backup of messages, contacts and pictures. Kindly guide me if I'm missing something.

I could see that I have to use adb root to take backup using pull command. Will the device warranty be there if I use adb root command?

For photos you can either copy them to the pc or use a third party app that will backup them,  like Google photos.

For contacts and sms there are plenty of third party apps.  You can alao backup the contacts to google server using the contacts app itself


unable to mount storage while installing new ROM - Nexus 5 i have nexus 5 rooted, its version was 4.4 i tried to upgrade it to 6.0 so i download the ROM (image-hammerhead-mob30y) from developers.google.com and i copy the image to the phone by adb push command and when i try to install the image i get the error unable to mount storage. however i cant wipe internal storage or dalvik cache from the wipe section in TWRP. also every-time i try to get root access to the shell using 'su' command i get the error /sbin/sh: su: not found

so what can i do to install the image? if the issue with the image what did you recommenced?

thanks

You don't install factory images in custom recoveries, let alone "flashing" them like regular custom ROMs.
XDA has you covered for simple stuff like this. Excerpt taken and simplified below:

Install adb and fastboot drivers.
Download the latest factory images
Extract the archive you downloaded.
Unlock your bootloader (In case you haven't already)
Power off your phone.
Boot it in fastboot by pressing and holding Power Button + Volume Down at the same time.
Connect your phone to your PC through your USB cable.
Execute the flash-all.bat script (for Windows) or flash-all.sh(for MAC and LINUX) in the folder where you extracted the factory images.
Wait for everything to flash.
After everything finished, select "Recovery" using the volume buttons.
When a small dead Android appears, press Power Button + Volume UP.
Select "Wipe data/factory data reset"
Reboot.


Notifications are very delayed on android - but only sometimes (apparently FIXED) I searched for my problem but what I found either wasn't answered or was very old response and maybe things have changed since then...

I just got a Samsung Galaxy S8 and it's amazing, but maybe since yesterday notifications are a bit slow. I just answered and email that I got an hour ago from my computer while my phone still didn't show the notification. I got some test messages and again, they showed up but only after I opened up gmail app and refreshed it.

What might help find the answer - right now I'm spending most of the time on my computer when I have gmail website opened (for hangouts) and thunderbird for emails. However the days before I was mostly outside with my laptop either turned off of inactive.

Btw, I had a similar issue with the old phone (also android) but I just blamed it being 4 years old and acting up.

So what could be the possible issue? Some kind of setting on my phone? Possible network changes? (I changed cities in those days, maybe the network here sucks and phone tries to use it instead of wifi... I'm just looking for options here). Or is it just the fact that I have gmail / thunderbird opened?

Thanks in advance.

One reason could be you have auto-sync turned of which is resulting in emails not being synced automatically.To enable this
Goto Setfings->Accounts & Sync ->tick Auto-Sync
also select your google account from there and make sure "Sync Gmail" option is ticked.
Another reason that may cause this can be battery savers.
Try turning of "battery saving mode" on your device and test again also turn off any 3rd party battery savers if you have any or white list the Gmail app in them.


How do I restore a contact I deleted on my Android phone, but not in GMail contacts? The contact in question had the wrong phone number in Viber, so I deleted it from Viber. I later found out that Viber had deleted it from my contacts, so I had lost all of the other correct information.

Logging in to GMail contacts on the desktop showed that the contact still existed. I proceeded to correct the faulty phone number and tried to sync my contacts from my phone, but this particular contact never shows up.

Is there any way around this?

Method 1
Stop syncing with Google account, check that all Google contacts are gone, set up sync again.

Method 2
Remove the Google account, add it again.

(You can do both in Accounts & Sync from phone Settings.)


How to differentiate between two LINE friends with the same name? Most users of the LINE messaging app have nicknames and profile pictures showing cats or characters.
Also, people switch names and pictures often, and profiles contain almost no info.

As a consequence, it can be very difficult to remember who is who:

Is there any way to differentiate between the two?
The long-press menu does not reveal any labelling/metadata option.
In the UI there is no visible ID or anything similar.

A solution is to rename your contacts:

Run the app
Select a contact
Select their name in the panel that appears
Click the pen icon as seen in the screenshot below
Edit their name to add for instance "(colleague)" or "(from the gym)"


Cyanogenmod custom recovery can't backup, restore or apply an update! I just installed Cyanogenmod. It's my understanding Cyanogenmod is a ROM so I was bit suprised when my TWRP custom recovery was replaced by Cyanogenmod's own recovery. Why is this?

Cyanogenmod's recovery can't do anything; it has no backup or restore options and each time I try to apply an update it says-

  signature verification failed.

Is it possible to get back to CWM or TWRP or somehow get Cyanogenmod's recovery to work?

I can't flash a new custom recovery from the phone since Cyanogenmod's recovery fails at flashing, and I tried using fastboot from the computer and it appears to flash TWRP but then it just goes by to Cyanogenmod's recovery.

I once read that TWRP/CWM only work with stock kernel and Cyanogenmod has it's own kernel so they won't work. Is this true?

I don't think it's relevant to the question but my phone is Xperia Z2 D6503 and the CM is 12 (Lollipop)

From xda thread: CyanogenMod recovery is basic, so you have to flash another one. The easiest way is to use rashr app and it worked for me perfectly


Can't switch/close tabs in the Chrome browser on my Android tablet I just recently purchased a cheap tablet (DigiLand DL701Q 8gb), as my first foray into Android.

I've been using the pre-installed Chrome browser but I can't figure out how to switch tabs or close them. I've searched for hours and all I could find was that the little square icon with numbers in the top right is the tool for tabs, but tapping it does nothing.

I've tried double/triple tapping and swiping, but it still does nothing. Tapping and holding on it opens a popup message with the phrase "open tabs" but tapping that also has no function. I've tried every combination and method I can think of, but nothing works. Only one time did I manage to switch to a different tab and then quickly close it, but this was a result of me desperately mashing the square icon in frustration and I haven't been able to replicate it.

I currently have 7 tabs open and I have no idea what they are or how to view them or how to close them. Any help would be greatly appreciated.

Click the three dots, choose "Settings", then turn off "Merge tabs and apps". Now tabs will work like they used to.

(This solution was improperly proposed as an edit by an anonymous user.)


Samsung Note 10.1 USB Ethernet I'm trying to get USB Ethernet support on my tablet, which for some reason is apparently disabled even though 4.1.2 directly supports it. (My Note II can use it...)  I've come to the conclusion that I'm going to need to essentially write everything on my own.  I'd prefer to write an app that can be used by other 10.1 users, but right now I'm just trying to get it working at all on my own device.  (I'm using a BobJ Ethernet->USB Adapter) Here are my current setbacks:

USB Host seems to shut down randomly.  This is the most irritating part, because it means I have to restart the device to use USB at all, mass storage included.  What should I use to diagnose this?  I've tried three different USB-specific apps from Play, but none of them give me much information besides the obvious. (That the host is not working.)
Even when the host controller is running and can detect the adapter, 'netcfg eth0 dhcp/up' doesn't work, claiming no device detected.  Does this mean the adapter driver is missing completely?

Each vendor is able to customize Android to suite their whimsy.

I'm using a $250USD Toshiba Thrive (OS 4.0.3), a Curtis KLU MID704 (OS 4.1.1, and one of the Rockchip clones) a Polaroid branded PMID704 and a ZTE phone. Of all these, the Polaroid and Curtis have Ethernet support in the settings. I'm using a Radio Shack Belkin USB-to-Ethernet adapter, which is supported off-the-shelf by Android. (Only the Toshiba Thrive has a full size type-A USB jack. The others need adapters, NOT available at radioshack.) The Polaroid is "broken" in that the Ethernet doesn't work. You click on it in settings and it clicks but does nothing. The crappy $75USD Curtis works, it shows me my IP and MAC address in settings and I can set static IP parameters including IP Address, Gateway, NetMask, and 2 DNS servers.

However, the Android frameworks (in the Java(tm)-like language) are broken. The connection managers only support WiFi and Mobile Data. You can inquire about the Eth0 device but can't open a connection or do anything with it.

So basically, your mileage may vary from mfr to mfr, and tabbly to tabbly.
Good luck!

Why won't my no SIM Android phone pair with an Android Wear watch? I have got a brand new Nexus 6, and brand new LG G Watch. Everything seems to work fine, but when I try and pair them, at the final stage the watch says "Just a minute" for a long time, and then finally goes to the dialog saying "Can't connect to the Internet. Swipe for some tips."

I've followed all the tips at g.co/AWhelp (https://support.google.com/androidwear/answer/6058728?rd=1) but nothing seems to work.

The only thing non-standard about my set-up is that the phone has no SIM card. I wanted to play with Android Wear development, and so it is a test/development device.

I eventually dove deep into this, taking bug reports, and wading through them. It turns out it is my ISP. Sigh.

My home ISP is BT. BT annoyingly use a service called Barefuit to interfere with DNS, at this seems to break the Android Wear check to see if internet connection is present.

Anyway, link 17a here takes you to the BT preferences page, where you can turn this off. Having turned it off, everything works fine.

I guess this is why Google have "try using just mobile data" at the bottom of their help page. If this happens to you, and you have mobile data, then do that. If you don't have mobile data, I'd try seeing if your ISP also uses  Barefruit, and complain loudly if they do (and try to turn off).


how do I get rid of this google searchbar? I have a Google searchbar in a tablet I have borrowed

For me it's in a very inconvenient location and I keep on pressing it accidentally.
It looks like I can't click and drag on it to move it to another location either.
How do I hide this toolbar? I need to be able to get it back as well, since the tablet isn't mine, but I want to hide or disable this search bar while I use it (or at least move it to another location)

The search bar is a built-in part of the default launcher and can't be moved or disabled. The least invasive way to get rid of it is to install a new launcher of your choice and use that instead of the default one. The old launcher is still installed, and will come back when you uninstall the new one, so the question is just whether you ought to install software on this device you've borrowed.


Galaxy s4 GTI9500 android version to update I'm having this phone for almost two years,
Currently running version 4.2.2 Jelly Bean, frankly don't have any known problems or bugs..
I think of upgrading to some of the Kitkat versions, as I know lollipop is still not stable.

My questions are:
1. Currently my phone give me the opportunity to update through FOTA to 4.3, which I've heard is a total catastrophe.
If I do this and than upgrade to 4.4 Kitkat do I collects some bugs on the way from 4.3?

Is it possible to upgrade via FOTA from 4.2.2 directly to 4.4?
Where can I find the new bugs\problems that I will probably have after upgrading from 4.2.2 to 4.4 KitKat, as I am more than fine with the current behavior of my current 4.2.2 version.
Same question as 3 but this time about new features that I will have.
Is it recommended to backup all phone content before firmware update?
What is the chance that my phone will turn into a brick after a firmware
update or will loose information?

I have an S4 on Verizon. I haven't had any issues since the update to Lollipop or before that with Kit-Kat. However the Lollipop update took up a lot of space on my phone which was a pain.
If I were you I'd go straight to Lollipop which, if I understand correctly what FOTA means, is FOTA capable. You shouldn't have any issues from the 4.3 'catastrophe' as you put it. I will warn you though, lollipop changes the look of a lot of things that do take some getting used to. But I've had it for over a month now and I like it same or better than before. I get much better battery life with Battery Save Mode, just don't use it all the time or it becomes ineffective.


Save merged contacts information I just spent a lot of time merging contacts from different sources (two Google accounts, Google+, Twitter, Facebook, Skype), and now my contact list looks somewhat clean for the first time in months. So far so good.

In the past, when I reset my phone (I'm a CyanogenMod user, so resetting my phone happens from time to time), I lost all info about merged contacts, which is really a pain. Is it possible to back up and restore this information somewhere, e.g. through an app?

edit: I did the merging in the stock contact manager of Ice Cream Sandwich (CM 9 alpha)

Your contacts should all be backed up to the Google account you registered your phone with, provided that you are saving your contacts to Google and not your SIM card.  Check to make sure that you are using Google as your default contact list, and that syncing for contacts for that account is checked.

UPDATE:
You can use Titanium Backup to migrate settings between ROM wipes for other apps/contacts.


How can I determine which block device corresponds to internal memory? Premable: My MP707 phone gave me an "overheated battery" panic message earlier in the summer, adn told me to take out the battery immediately. (It had been sitting in the sun, and was probably just confused about the source of the heat, but I didn't think of this at the time, alas.) So I opened it up and took out the battery...without a shutdown first.

The next time I started it up, I got a warning about internal storage being damaged, and did I want to reformat it. Note: internal storage, not the SD card! I found that images and recordings I'd made were no longer accessible, and the voice recorder didn't want to function because it couldn't find a place to store the recordings.

Not long after, the phone started shutting down at random, and then wouldn't start up at all. I ordered a new battery, and went back to using my old phone.

A few days ago, I picked up the MP707 and it turned on just fine! (Still gave me the damaged memory warning) And as far as I can tell -- I'm a newbie in this phone stuff -- the internal storage seems to have gone missing.

The meat of the question: Following the advice here How can I recover a deleted file on android I managed to root the phone, install a terminal program, and start poking around. I'd like to do a raw copy of that internal memory, in hopes of recovering one or two things. But the first instruction is "Find out on which block device the file was on. Via mount". Well, mount tells me this:

(I can't figure out how to copy/paste from VNCLite...sorry).

Can anyone, looking at this, guess which mount point corresponds to internal memory, or tell me how I might determine this?

As Izzy said INTERNAL STORAGE usually refers to /data, it's the partition where apps are installed and where they keep their private data.

Also /storage/sdcard0 could be part of internal phone memory, called PHONE STORAGE it's an emulated sdcard (I can't tell if in your case that's emulated sdcard or real)

To make a raw backup of your data you need to know which block contains that partition, you can check it with this command:

cat /proc/emmc

Result should contain lines like this:

emmc_p7: 001a4c00 00300000 "usrdata"
emmc_p8: 004a4c00 0358dd00 "fat"

This gives you partition number p7 , now you can use this command to list blocks:

 cat /proc/partitions

Result should contain:

  179        7    1572864 mmcblk0p7
  179        8   28077696 mmcblk0p8

In this case to backup /data aka emmc@usrdata contained in mmcblk0p7 block you can use this command:

dd if=/dev/block/mmcblk0p7 of=/storage/sdcard0/usrdata.img

Supposing sdcard0 is working properly and there is enough space.
After that usrdata.img can be mounted in a linux box with:

sudo mount -t ext4 -o loop usrdata.img ./folder

P.S.
You might check how to use adb so you can open a console on your computer and issue commands to your phone connected with usb.


Only my phone cannot connect to only one specific WiFi Ok so Ive seen plenty of problems where peoples phones can't detect any WiFi networks, or if a particular router can't connect with mobiles, but I don't have any of those problems. My problem is very specific: My office WiFi is not visible on my phones WiFi list, but everyone elses phones can connect just fine. However, my phone can connect to every other WiFi with no problem. In fact, every other WiFi (21 of them) on my laptops list is also visible on my phone. It is only my office WiFi which is not visible. This happened after a WiFi upgrade a few months ago. Does anyone have any idea what could be causing this?

Android version: 6.0

Phone: Moto G 2nd generation

This happens quite a few times. According to my observations. I have noticed the main reason behind this is entering a wrong key (password) to the wifi network which makes it temporarily disabled from the wifi list of the phone. Try forgetting the network which you may have connected once and reconnect to the same network with correct password.


Call custom emergency number from lockscreen Ok, basically, what I want, is to provide Android phone to child, locked by passcode (or gesture), and allow the child to call parents (two numbers) from locked device.

My current available target device is SDK 22, Android 5.1, but I will not limit the answers to this target.

What is not correct answer:

something along the lines of setting ICE info, this won't allow to call, just to display ICE phone numbers
modifying the SIM card data, as this is not possible generally and not available in my case
solutions requiring ROOTing the device, as this is not possible in my case
solutions using CALL_PRIVILEGED, as this permission is protected and not achievable without ROOTing the device or having custom ROM
Solutions using Samsung or other proprietary emergency dialers, as the devices I target, do not use any such measure, and look like this

What I've tried to do is

Creating custom notification intent on the lockscreen, which would use ACTION_CALL intent and android.permission.CALL_PHONE permission

this is not working solution, as CALL_PHONE requires unlocking the device

Creating custom notification intent on the lockscreen, which would send out SMS to pre-defined numbers

this works, however it might be pricey, and I consider this the last resort option
this also does/might not resolve the emergency cases, child might got into, because the reaction time depends on parents having the phone volume up and calling back right-away

The feature you are looking for already exists in Android 7.0+. Upgrade your device if you can.


How do I know which root method was used to root a phone? Let's say you got a rooted Android phone but you want to find out how it was rooted.  Is there a way to know which method was used to root it?

In general, no.

The basic goal of rooting is to place an executable su binary somewhere accessible via $PATH.  Nothing else needs to be left behind.  The specific exploit that was used need not have side-effects, and multiple different tools could use the same exploit anyways.  In fact, there need not even be an exploit — many devices just let you unlock the bootloader and flash or otherwise load su in a straightforward manner.

If you know that a specific root tool does leave behind a signature, you could check for it, but in my experience that is not typical.


How can I set some handy settings on the main screen? I want to be able to set Wifi, bluetooth, GPS on and off quite easily but I can't find where I should do this.

You can add the Power Control widget to the home screen to control those functions. Open the app drawer, find the Power Control widget, long press and drag it to the home screen.

There are also many widgets in the market that offer expanded functionality when compared to the stock widget.


How to set default contact store location, android 4.4.2, LG L9 II? I need to set up  the default store place for contacts as now every time it wants to save to sim card which is not as functional. I have to change it, dismiss the warning about lost information (even with zero info entered and phone allowing for more information to be entered).

I read the answers here, but they do not work. In contacts>settings there are only:
- the display options (contacts to display, sort search results by, sort list by, view contacts names as, only contacts with phones)
- general info (sync now, accounts & sync, online search, transfer type)

I do not believe that it's impossible to choose the default store location. Even 10 year old phones are capable of these settings. I just can't find these settings. Hopefully someone knows

After trying all the solutions I found online, I found the one what works for my phone:
Settings>Apps>All Apps>Contacts (not contact storage) and clear data.
Now contacts are saved to phone.

I also chose to display only phone contacts, but without clearing data on the contacts app, it  didn't work.


Will flashing ROMs multiple times degrade the performance of phone? Will flashing ROMs multiple times degrade the performance of phone?  If yes, is it possible to retain the performance? If no, then is there any procedure or sequence to flash a ROM on a Samsung Galaxy S?

If you always wipe the device between ROMs (clear system, boot, cache, etc [not data]), then there should never be any degradation of performance. While flash memory does have a theoretical write limit, you won't make any sort of noticeable dent in the life of the device by constantly switching ROMs to try out new ones.

However, if you don't do a full wipe, you could see performance issues creep up. More likely, you'll run into bugs and random crashes as files left over from a previous ROM conflict with the new ROM. This is why you should always do a full wipe if you are installing a brand new ROM.

As for how to flash a ROM for your particular device, xda-developer forums for the Galaxy S are a good place to look. They list instructions on how to root the phone, install ROMs, and other helpful guides.


HTC One / Beats Earbud Conflict The Beats earbuds that came with my HTC One initially worked great: the inline control worked, sounded decent. Recently, the phone fails to recognize them however. When I plug in alternative earbuds the phone plays music through the alts. When I plug the Beats earbuds into  alternative audio sources, the earbuds themselves work fine.

There appears to be a conflict between the two together:

I have tried using the headphone controls apps to see if throwing an app in there dedicated to managing the earbud controls would be a workaround and this did not work.
When I plug the Beats earbuds in, music plays through the phone speaker but the earbuds make the noise they would due to being plugged into a sound source
I have tried this with the Beats Audio setting on and off, and it is not a separate volume settings issue as the phone plays music through itself instead of the earbuds
Essentially, the issue isn't even with the inline controls, it is with audio not coming out at all; having audio come out of them would suffice a win for me

What are my options and which are the best:

Get a new set of the same headphones; confirm if the issue is with this specific pair, and perhaps a short inline or other wear issue?
Is there some kind of Software solution?
Is the phone the problem even if other headphones work with it?

Problem
I have been recently using my beats tour with my HTC One. It was working fine and then it stopped working. First I thought either my phone had a problem or the earphones. I thought of claiming my warranty but, before that I did following tests:

Plugged different earphones in my HTC One from Apple, Samsung and HTC. All worked fine.
Plugged my Beats earphone with iPhone, iPod and my computer. It was working fine too.

Analysis
Then I compared the connector of Beats earphone with others. I noticed a potential design flaw with both Beats connector and HTC One:

Beats earphone connector radius is slightly smaller than normal earphone connectors.
HTC One internal connector was pushed in more when plugging and unplugging earphone.
(I don't exactly know words to explain this but, this usually happens with electronics when using cheap materials).

Solution
As I am sure both HTC and Beats won't be accepting these facts. I recommend you to buy a short extender. I connected my extender to my HTC One and Beats earphone and it worked like expected.

I am not sure if we lose quality when using a cheaper extender.


How do I stop the 3g/4g radio from turning off? When I watch youtube videos on my samsung epic 4g, most of the time when I click a video to watch it does the "Loading" spin gif animation forever, and I can see the little arrows on the 3g/4g symbol are off.

If I hit back and load again 3 - 5 times the arrows light up and the video acutally plays.

This is incredibly irritating.

Is there a way I can tell the phone to always keep the radio connection active while the charger is plugging in, or something like that?

Alternatively, does anyone know how if there is another way to fix this youtube issue?

Thanks so much, this is driving me crazy.

If you see the 3G/4G symbol and the arrows are just grey, that just means that you have data connectivity but there is no send or receive activity at the moment.

I guess you made an false assumption: The data radio is only off (deactivated) if you don't see the the symbol at all. Otherwise, if the symbol is there and the arrows are grey, your radio is on, but there is no traffic happening at the moment.


Strange WiFi battery usage on Marshmallow Nexus 5 I have a question about the WiFi battery usage on the Nexus 5. In the first screenshot you see my battery/WiFi usage. The second screenshot shows the battery/WiFi usage for the Nexus 5 of a colleague of mine.

Strangely enough, my WiFi is disabled. Why is this so?

There is a known issue on Nexus 5/6 with Marshmallow and wifi. This wifi drain has been noted by many users, me included.

How can I get apps from the Amazon app store from an unsupported region? Currently, the Amazon app store appears to be US-only.  Similar to How do I use the US Android Market from Europe?, I want to know: How can I use the US Amazon Appstore?

Market Enabler doesn't seem to work, and it's not IP-based like I previously thought.  Any suggestions?

You have to "prove" to be a US resident by accessing the store with a US based IP once. It's sufficient to use a US proxy.

Additionally, you need a US credit card with a US billing address to buy apps; to download free apps, you can fake the number (all 0's will work) and address.  Then ensure 1-click ordering is turned on in your Amazon.com account (the Appstore will prompt you to do this and provide a link).  A prepaid credit card in USD might be a good way to do this for people outside the US, I'm not sure.

Some users seem to be reporting that Amazon is now blocking non-US IP addresses.  This isn't 100% accurate, since I access the app every day from Canada with no issues.  It may block specific countries though, in which case you'll need a US-based proxy/VPN.  Make sure you trust it, so that your account credentials aren't compromised; don't use Tor / Orbot!


What is the default browser of Android 5.0 and above? Android devices used to have its stock web browser as its default browser, but nowadays, it is replaced by Chrome. And it is said that the default browser of Android 5.0 and above is going to be Chrome. Having said that, what happens if a phone with stock web browser is updated to Android 5.0? Is its stock web browser is deleted as well as replaced by Chrome? Or does it stay as its stock web browser even after the update?
If there is any web-site that could support your answer, please attatch its URL as well.

Thanks.

Lollipop has chrome as its default browser. Even devices which had native browser on KitKat deletes the native browser upon lollipop update.


Apps are crashing endlessly even after a factory reset, preventing me from doing anything Some apps are crashing endlessly, and I can't do anything because they just keep giving me the same errors.

I've even done a wipe-out/factory reset, but the problem still persists.

This problem was first started long time ago when my battery had problem and my phone just shut down in the middle of work. When I replaced my battery and reset my phone all of my problems were solved. But recently, I mean 5-6 months after replacement, my contact and dialer app started to give me that error. I installed another dialer and contact app and I thought that if I do a reset it will fix it, and when finally I did a factory reset my setup wizard and social plugin and contact and some other apps just have this error.

My Android version is 6.0 and is stock official.

It seems like your firmware are broken, you can try to reflash the firmware, or Install a custom rom. Have also a look in xda in your phone thread maybe this problem has anyone before you.


Find out which app is pushing ads in my notification bar? This may be a duplicate question but it seems the bad guy has improved its technology and known methods don't work so far.

My question is what else can I do to find out which app is pushing ads? I don't want to try airpush opt out for two reasons:

I wouldn't trust people doing this at the first place.
I want to find out which app is doing this and add the company/developer behind it to my black list.

UPDATE

My phone is a rooted Samsung Captivate Glide, Android 2.3.

UPDATE

Updated to 4.0.4

Thanks

Beginning with 4.1 Jelly Bean, you can long-press the notification itself. This will bring up a menu with a single item, "App Info". Touch this item and you will go straight to the offending app's management page, where you're just a touch away from "Force stop" and "Uninstall".


Who can see how many people have uninstalled an app? A few months ago I installed a free comic viewer app from a local publisher because I always have bought the comics on paper anyway so it seemed a logical way to do.

This publisher is boasting about the thousands of downloads he got for his app.

However, having seen the app, I uninstalled it the day after because it simply was not good enough (and took to much memory).

So I am just wondering: we always see how many downloads an app has. But can we see somewhere how many uninstalls have occurred?

There is no way to see this fro the user's end.   Generally read through the comments.  People are very vocal about their opinion.  And if it has truly been uninstalled that many times, beleive me, people will say why and you will get a good indication.

And yes, a developer does get daily statistics on installs/uninstalls.
