How to show only gmail's contacts in the Contacts app? I have recently reinstalled Android due to some problems with the SD Card.
I decided to keep all my contacts only in Gmail, as a centralized solution to avoid problems in the future. I do not want other SIM or phone contacts to show in the contacts list anymore.
However if I try to uncheck both the SIM and phone contacts and I do check all possible google contacts groups and the option for showing only contacts with a phone number1, no contact is shown at all.
Note: If I show also the phone contacts them the google contacts are shown (and thus I have some duplicates), but removing the phone contacts removes the google contacts too.
How can I prevent this?
The phone is a B63M.
Edit: since people keep asking the same information:
The contacts are perfectly synched and all under the My contacts group. It's not a synchronisation problem. I'm asking why I must select the show phone contacts in order to see any contact at all (from whichever source you like. Even SIM. I cannot show only the SIM contacts without the show phone contacts enabled.)

1 Having or not this option active doesn't change anything. Even if it is not active no contact is shown.

Updated
To make things clearer, here are some screenshots of the situation:
Here I have set only the phone contacts (Contatti del telefono in Italian), without google contacts:

Here I have added the google contacts in the options and they are shown (see red rectangles. Note the number of contacts at the top going from 116 to 156):

Now, I'd expect that removing the phone contacts I should see only the google contacts (in this case those that above have red rectangles and the other not shown), but this is what I get:

On the right it just says that there are no contacts to show and that I can add new contacts or import/export from other sources.
What should I do such that this last set of options does show the google contacts?

Go to Contacts > [Sitting Button] > More > Accounts.

Be sure the following are checked:

Background data.
Auto-sync.

Contacts/People > Menu > Contacts to Display > select your gmail account to display.


Dialer is very slow between dialing the number and getting into the call: spinning wheel for 5-10 seconds I have a Nexus 4 with CM (latest version). For the last few months whenever I dial a number it takes anywhere from 5-10 seconds for the actual call to start.

I checked Android SE and didn't find anything except for this: Dialer app becoming too slow and less responsive.

However, my case I believe is different. The question above asks about the actual dialer start-up time.

In my case, the dialer is very response: whenever I tap on the Phone icon in the tray, it shows up immediately (the stock Android dialer that comes with CM): I can switch between favourite contacts, recent contacts, search contacts and the dialer with no issues.

However, once I find the contact I need or dial the number and then tap to call, the screen goes black with a spinning wheel in the middle:

Spinning Wheel After Dialing a Number/Contact (click image for larger variant)

This takes about 5-10 seconds like I mentioned.

Once that time passes, it goes to the actual call where I can see the phone number, the contact picture (if available), the drop-call red button, etc.:

The Actual Call Screen after the Spinning Wheel (click image for larger variant)

What I've tried:

Tried using a different dialer thinking maybe it's the issue with the stock dialer: no difference. Tried exDialer and some other, results are same: the dialer itself is snappy, but after tapping the call it goes to the spinning wheel on the black background.
I don't think it's a memory issue as I have 2Gb I think. In any case, with all the text messages I have (I don't delete any), all the contacts I have (including hundreds of Google+ random dudes I follow), the Phone app itself is snappy: everything works very quick.

Any suggestions are welcome as it's getting very frustrating! Thanks

I had the same issue.
So, after a lot of work and tests, I've discovered that what was causing the issue was the Prey app. Do you have the Pray app (or similar) installed on your device, perhaps?

After I've removed it, the dialer came back to work normally.

Hope it helps.

I Uninstalled linkedin and problem went away.


Galaxy S7 Nougat--When charging, screening keeps coming on Recently upgraded to Nougat on my Samsung Galaxy S7.  Only issue is that when i am charging , the screen keeps turning on to show it is charging, then goes dark, then turns on again.  The only way to mitigate, is to turn on the screensaver when charging.  any thoughts?

Try checking "Stay awake" in developer options which makes the screen never sleep while charging.


How can I deal with "Low on Space" messages on my Android? I keep getting the "Low on Space: Application data space is low. To free up" [the rest is cut off] message.

I've moved every app I can over to the SD card, cleared the cache, compacted my K9 mail cache.

Advanced Task Killer (ouch!) says I have 98M Available Memory

File Manager says I have 223M/748M (29%) free.

That's not so bad -- but I'm stuck in the no-updates scenario. The market downloads won't really start, gmail won't update, etc. I've rebooted several times, and nothing changes. Aaaargh.

What can be done, other than uninstalling everything ?

This timely post from Lifehacker may help... Were you the one who emailed them? ;)

What Should I Do When My Android Runs Out of App Space?

Here's the summary, in order of easy to hard:

Move Bigger Apps to SD Storage - currently requires Froyo (2.2). Navigate to
Settings > Applications > Manage Applications (or something similar). View the All Tab, sort by size. You can't do anything about the big hitters, namely Gmail, Browser and Maps will always be pretty big.
Clear the Cache, and Maybe Data, on Some Apps Similar to #1, navigate to Settings > Applications.
Clear Out Apps You Don't Actually Use Shouldn't this be #1? ;)
Android 2.2: Set Your SD Card as the Default Installation Location LifeHacker points to the Androinica blog how-to here.
Root Your Phone and Set Up Apps2SD Disclaimer: rooting may not be fun for non-geeks. LifeHacker how-to-root and custom firmware CyanogenMOD (also supplied by LifeHacker).

Of course some of the comments on the post are helpful as well. Hope it helps.

I tried all the standard cache cleaning and uninstalling updates which helped a lot. I tried storage analyser but that didn't help the internal storage. Wasn't keen on rooting the phone. Then I came across Clean Master and used it on my wife's Samsung Ace which is notoriously short on internal memory and no option to move most apps to the SD card. So far so good.


How to recover glitching Galaxy S9? The bad
Last week I totaled a Galaxy S9's screen which I owned for over two years. I liked the phone so I headed up on Facebook market to look for another one.
I discovered a phone that I liked and went on to buy it.
When I had the phone in my hands, before paying, I run a service code (#0011# to see if all sensors/screen etc worked). This passed so I bought the phone.
Also, the phone won't do Samsung updates. It would either throw an error after download (The downloaded file is not correct) or restart when attempting.
The ugly
Here's the harsh part: not long after leaving the dodgy seller, while going home, the phone started behaving really weirdly: sudden restarts, some screen glitches, and artifacts. The phone also loses battery pretty quickly, either due to the weird sudden restarts or else.

Note the purple glitches. I was able to record these with a screenshot, meaning it comes from the GPU chip?
The good
The first thing I looked at was the water damage sticker beneath the sim tray:

I then managed to charge the phone fully and log in with a Google account, which allowed me to do further diagnostics. I installed Geekbench and run a test. The phone has a normal score for this model.
I tried filming, calling, playing games on the phone and all seems well.
The only times when the phone restarts are after receiving an error like "Google Services App crashed" or "Samsung Services App crashed" or suddenly when I try to use a service or disable/uninstall blootware.
I also managed to get the phone to update through Samsung Smart Switch to the latest update (Security Patch 1 Dec 2020)
Resolution:
I have a few options for repairing this weird phone

Find what version of firmware I could flash on the phone and hope for a stock experience (including bootloader etc) - This option assumes that the hardware is intact, the chipset has no water damage, etc.

Open the, in which case I lose IP68 (assuming this is not lost already) and change the motherboard with my old phone's.

How to proceed from here?
I am a bit unfamiliar with choosing the right firmware etc. I have the following information in the phone's software info:

One U.I 2.1

Android 10

Baseband version: G960FXXSBETG8

Kernel version: 4.9.118-18847185 # 1 Mon Aug KST 2020

Build number QP1A.190711.020.G960FXXSBETH1

Knox 3.4.1 API level 30 TIMA 4.0.0

Service provider SW ver.: SAOMC_SM-G960F_CKH_DRE_QQ_0009 / 2b282a7f23017ece (DRE/DRE/DRE)

CSC: G960FCKHCFTK1

AP: G960FXXSCFTK2

CP: G960FXXUCFTJ1

I tried downloading this firmware version, but from what I've read the bootloader version here is too old and cannot replace the current bootloader. How can I determine the bootloader version on my phone? XDA forums say it's the 5th digit from the Build Number. However, my Build Number doesn't seem to respect the format of the above file.
Can anyone suggest what to do next? I'm itching to open the phone, but I think it's wiser to try and repair it from firmware.

bootloader level is increased in 1 digit
1 2 3 4 5 6 7 8 9 A B C D
G960FXXSBETH1 = B
G960FXXUCFTJ1 = C
you can download rom for SM-G960F from updato, samfirm, frija or samloader. try lowest bootloader first, as you already stated downgrade is impossible (and higher version usually comes with higher protection against rooting). you can check bootloader version from download mode screen

Thank you alecxs for your support. It kept restarting and showing a bicolour (green/blue) padlock which I assumed was a security feature from the carrier. The phone will work for extended periods of time, however, it would randomly restart when using standard google/samsung services, even with a new firmware.


How to Screenshot Of the Screen on Samsung Galaxy S 2? Since i have updated my phone by Android version 4.0.3 i am not able to take a screen shot of my phone, before i used to do it by pressing Home and Power button simultaneously.

Now if i am pressing Home and Power button simultaneously it open up Task Manager.

Can someone explain me how to fix this issue.

Thanks in advance.
Regards
Sam

On my Galaxy S3 it is Home and Power but they need to be held in for about 1 second but it may be different on the S2

EDIT: According to this Samsung have changed the Screen shot buttons to be Volume down + power on some firmware versions and on others it is Power + home heald for about 2 seconds. Hope that helps

i was on the same situation like yours.. my S2 updated about one month ago.. do press your home button together with lock or power button and hold it for about 2 seconds.. press it together not separately and hold.. best of luck.. ;)


How to restore ColorNote notes after factory reset? I forgot to backup my notes before factory reset and now apparently I have lost them all. Before doing factory reset though, Back up my data option in Settings >> Backup & Restore was checked but right after it there was no sign of restoring data and such. I am not however sure if this has backed up any of my ColorNote app data.

There is a backup folder at this address /storage/emulated/0/backup which contains backup files for some applications including one file named com.socialnmobile.dictapps.notepad.color.note which should be related to ColorNote app. When I double click on this file, and install it, no note gets restored. I also did not have anything synced with my Google account before doing factory reset.

I know I have probably lost my notes, but still am desperately searching for some way to restore them! Those notes where stored on Androids file system, so my only hope for now is maybe I could use some file recovery application to recover those deleted files. Any advice and help would be greatly appreciated!

(Galaxy Nexus, Android version: 4.2.1, not rooted)

If you have the db files then the only way is to root your mobile and copy the corresponding db files to the location(data/data/com.socialnmobile.dictapps.notepad.color.note).

As I know: factory reset => erase all data. It is good to make a backup.. but sadly the backup is not working all the time and is not working for all applications. I'm sorry dude, you cannot recover your data. You could try at a GSM service... maybe some specialist can do something, but I don't think so.


How to create an update.zip file that can copy & rename a file? Here's exactly what I'm looking for - I need an 'update.zip' file that can copy a file (example):

/system/framework/file-to-copy.apk

to another folder:

/system/

and then it would rename the 'file-to-copy.apk' in the 'system' folder to:

renamed-file.apk

and copy it back to:

/system/framework/

It would have to overwrite an already existing 'renamed-file.apk' in 'system/framework' folder.

Note: The permissions can NOT change.

Is it even possible to do this?

Any help would be appreciated!

Actually you can do that by using the run_program syntax in updater-script to execute a shell script that moves/copies/pastes files while in recovery. But of course, you must extract the files that are to be pasted in somewhere (/tmp for instance).

Part of the updater-script:

package_extract_dir("stuff", "/tmp/stuff");
set_perm(0, 0, 0755, "/tmp/stuff/movefiles.sh");
run_program("/tmp/stuff/movefiles.sh");

The sample shell script can be like this (named movefiles.sh in this case):

#!/sbin/sh
# Backup files
cp /system/framwork/something.apk /path/you/want

# Paste files
cp /tmp/somethingssss.apk /system/framework/something.apk

# Set back permissions (the copied file has the same permissons, but the new ones does not)
chmod 644 /system/framework/something.apk

But remember, the EOL of updater-script and the shell script must be the same, in UNIX format, or else it won't work.

You cannot execute zip files.

You can move/delete/rename a file in /system/ via adb but you must remount /system/ as writable.


Unable to change permissions for files on external storage To clear up some disk space I moved my mp3 collection from internal to external storage.  My device is rooted and I was su at the time.

The files can be seen (and played) from the File Manager, but none of my music players see them.

What looked interesting was the file permissions after moving.   Here's a file still on internal storage that wasn't moved.

root@kltetmo:/data/media/0/Download/mp3 # ll
-rw-rw-r--    1 1023     1023       6730901 Aug 25 16:03 fatamix_upd_start_20160824(2).mp3
root@kltetmo:/data/media/0/Download/mp3 #

And here are a couple files that were moved to external storage:

root@kltetmo:/storage/sdcard1/Music/Bat for Lashes/Fur and Gold # ll
-rwxrwx---    1 root     1028       5887321 Jul 16  2015 01 - Horse And I.mp3
-rwxrwx---    1 root     1028       5894753 Jul 16  2015 04 - What's A Girl To Do_.mp3

Moving them to external storage appears to have changed permissions.  Unfortunately, chmod is not affecting the actual file permissions:

root@kltetmo:/storage/sdcard1/Music/Bat for Lashes/Fur and Gold # ll
-rwxrwx---    1 root     1028       5887321 Jul 16  2015 01 - Horse And I.mp3
-rwxrwx---    1 root     1028       5894753 Jul 16  2015 04 - What's A Girl To Do_.mp3
root@kltetmo:/storage/sdcard1/Music/Bat for Lashes/Fur and Gold # chmod 664 01\ -\ Horse\ And\ I.mp3
root@kltetmo:/storage/sdcard1/Music/Bat for Lashes/Fur and Gold # ll

-rwxrwx---    1 root     1028       5894753 Jul 16  2015 04 - What's A Girl To Do_.mp3

I tried moving the file back to internal storage to change permissions there.  This worked until I moved the file back to external storage.. moving it definitely changed permissions to 770.

root@kltetmo:/data/media/0/Music # ll

What do I need to do to reset permissions so these files can be seen and played from my default music app?

This application fixed the issue i had like you.


Weird Octopus icon, Joy Launcher on Alcatel this weird thing happened today, an octopus icon appeared on screen. Alcatel. It's annoying. Linked to Joy Launcher, which can't be disabled.
Any idea how I can turn it off?
Not the same as other question about Joy Launcher

I went into Settings → Apps → Joy Launcher, and then pressed a little cog in the top right which resets Joy Launcher back to its default (original) state. But it also resets your home page back to default.

Factory reset disable auto updates was my solution, not the best but was so freaked out that it had to be done.


Are all apps on Google Play compatible with the Samsung Galaxy S4? I wanted to know whether the Samsung Galaxy S4 will run every app from the play store or not? I had done a lot of googling but failed to find an answer.

In general, NO.

Some apps:

run on specific devices only (i.e. not compatible with S4)
run on specific Android versions
available only in specific countries
available only on specific carriers
requires root access. (i.e. if phone is not rooted, it won't work)

I would say 80% app is compatible. And other 20% are for other specific devices. Specific android version and  specific screen size


Cyanogenmod no service? I had cm-11-20150517-NIGHTLY working, then upgraded to cm-11-20150607-NIGHTLY. Now I get the error "No service" and have basically no GSM functionality whatsoever.

If I attempt to select a network operator, I get the error: "Error while searching for networks."

I installed this using TWRP, there were no issues with the install. Automatic upgrade failed, I believe this is due to an encrypted file system, something which TWRP does not handle.

What I have tried:

Rebooting by itself.

Removing the USB cable and rebooting (apparently this was a known issue before).

Reverting to cm-11-20150517-NIGHTLY, this does nothing, same problem.

Resetting APNs to default.

Device: GT-N7100,
CyanogenMod version: 11-20150517-NIGHTLY-n7100,
Android version: 4.4.4

Solution was to restore a backup of /efs and write a backup of the modem firmware to /dev/block/mmcblk0p10, this device file may be different on a different deivce though. But on my N7100 it worked.

I finally got a solution to "no service " after installing cyanogenmod 7 on HTC incredible 2. the ans is simple and est and does not have anything to do with flashing radios, reinstalling rom. simply turn the phone of and remove ye battery to take out yr sim card and switch it bak on without the sim. in it. after it has finished rebooting,
make sure the network bars are appearing even without any signal. I e, an x sign on the bars and dat. also airplane mode is off. now go to mobile network settings and choose cdma/GSM (auto) and not the preferred one. now of phone and put bak. sim in and tadaaa, yr. phone will have de most amazing. connection!

Allowing a computer to connect to wifi from android  already connected to wifi. A unique situation writing from my phone so sorry for typos.

I recently fixed my laptop but the wireless network in my house doesn't work on it (its probably router configuration problem-or at least could be fixed with configuring the router, but I have no access to the router since I am renting).

The network works fine on my sanyo zio which has no money on the account and no plan (so the only thing I can use this phone is for internet if I have wifi access). I want to use my phones ability to connect to the home wi-fi network to connect my laptop to that network (so transfer the home wi-fi to the laptop through my phone). Usb connection or wifi will do as I am pretty sure its input this home wi-fi that doesn't work. So if I turn my zio into a hotspot it should work.

Is there any way to do that?
To make situation better I have vista 64 so kyocera divers for this phone don't work.

Update:
I forgot to mention that for some forsaken reason (I suspect murphy's law) the bluetooth internet  connection on my computer fail s when I try to connect it with my phone. (following instructions on fifox and manually connecting with the blue tooth dial up option which just times out. I'm missing some peripheral bluetooth driver ;/) I can connect to my phone through bluetooth just the internet option fails @.@
.
And I don't think my phone supports the wifi option through fox fi.
Although I have no way to be sure. When I turn on the hotspot option the internet connects but with limited access (just like my home network but I think its because my phone doesn't tether right not because of my laptop. Ofc I could be wrong) it says that might happen and to just automatically get new ip to fix this problem but that doesn't work also says many phones are not supported for wifi and I don't think this one is.

update

I Recently rooted my phone. I tried the apps for the rooted phones but they just want to use 3g network connection. Since I want to connect, through wifi they are quite useless. Anybody has an idea what I could download or do to make this work for me?

What you're referring to is called tethering - using the data connection of your phone to share internet connectivity to another device.

Look for tethering options in the settings > Wireless menu or other locations in case your manufacturer has placed it elsewhere.

Failing that, consider using an app like FoxFi or some other tethering app.

Also, a search on Android.SE reveals a number of similar questions - please use the provided functionality. Here's an answered question that might be relevant - Can I use my Android device as Wi-Fi Adapter for my PC (i.e. Tethering to PC through USB, but using Wi-Fi not Phone Network)?

You want your Android device to re-broadcast an existing Wi-Fi network to act as a Wi-Fi Repeater. Technically, its possible from Software layer, but such implementations aren't available for Android yet.

You can do any of following things now:

Do it with pure Linux way (Android is a Linux distro) using Hostapd type software. Installation and configuration wouldn't be easy, by the way.
Share Wi-Fi internet using Bluetooth DUN. Its the easiest way. I don't know what difficulties your PC bluetooth is facing, but try PdaNet or Open Garden .
Turn off Mobile Data and do USB Tethering. It starts to share Wi-Fi internet on some devices. Its not universal method, but see if it works for you or not. You can also use PdaNet for better USB Tethering.


What would happen if I deleted all my data used by Google Play Services? Unfortunately my phone has a total space of 5.52GB with no place for extra storage ... Sad, I know.. However my phone is constantly rejecting texts and won't keep an app open for more than 2 minutes without crashing. I clear my cached data almost every ten minutes. My phone isn't full by any means. I only have Facebook and Snapchat as apps and only 168MB of pictures and videos.

So I decided to dig a little deeper to figure out where all my storage is and under my Google Play services it says I have 3.9GB just there! What I'm wondering is what exactly Google Play Services entails. For example, what would I be losing if I cleared all of its data? Would I lose pictures and apps?

Google Play services offers APIs to other apps. Data used by Play services is mostly cached data for these APIs, duplicated data of Android wear apps synched with your phone and some kind of search index. If you delete this data, chances are Google Play services will just recreate it, although 3.9 GB is really much (mine only use 300 MB). But you won't delete any of your personal data by deleting Play services data.

Here's what the Google Help forum suggests:

  Make sure you have an Internet or mobile data connection. Then, restart your device.
  Update the date and time on your device.
  Clear cache data for the Google Play Store app and Google Play Services (Go to Settings > Apps or Application Manager > Google Play Services > Clear cache > OK).
  Uninstall and reinstall the Play Store updates. (Go to Settings > Apps or Application Manager > Google Play Store app > Uninstall Updates > OK). As long as you have a strong Internet connection (Wi-Fi or mobile data), your Play Store app will update to the latest version within a few minutes.
  Install system updates. To do this, try the steps listed below:

  Open your device's main Settings app.
  Select About or System updates (depending on your device, this may be different).
  If an update is available, follow the on-screen instructions to install it on your device.
  Try your download again

  Restart your device.

If the issue still persists after having tried the above, the same place recommends removing and re-adding your Google account.


Names not shown from number anymore All of a sudden, half-way using whatsapp, the names are not shown anymore. Instead I can only see the number. I went to my contact list and checked.

Most of my contacts appeared to be shown in email address. And it's the same person's email address.

I clicked in and found that the detail of these contacts is gone.

What happened to my phone and what should I do?

My phone is Galaxy Note2

In Settings > Contacts > Show all contacts should be disabled which was the case for me but still had same problem. So I enabled "Show all contacts" and exited whatsapp. Launched Whatsapp again and disabled 'Show all contacts' and got the names back again instead of just phone numbers. Hope my experience helps.

Just reboot your phone after checking "Show all contacts" in settings it will work...


Is there a way to get a disk image of the user storage space on modern Android devices? I want to know if it's possible to get a "disk image" of the storage space on Android devices when they don't use external storage like SD cards.

I'm mostly interested because my kids factory reset my Kindle Fire HDX and I was hoping I could get a disk image (using something like dd in Linux) and then try to recover some of the user data like photos and videos (using something like PhotoRec, http://www.cgsecurity.org/wiki/PhotoRec).  I've done this lots of times with SD cards and hard disks by simply mounting the storage device in a desktop running Debian, and executing something like:

# dd if=/dev/sdb1 of=image.iso

Then you can use PhotoRec and/or TestDisk, depending on what you want, to get useful stuff out of the image file.

Even some of my very old Android devices seem to allow mounting a storage device in this way (without removing SD card from the phone) and following this process.  Unfortunately, it looks like many new devices that don't have removable storage (like my Kindle Fire HDX and my Nexus 5) only allow you to interface with a computer using Media Transfer Protocol (MTP) and Picture Transfer Protocol (PTP).

Can I use these protocols to get a bit-by-bit copy of the storage in the device?  Is there a way to add the older storage device capabilities to new phones?

After doing some more research, I think I've found a partial solution here:

http://forum.xda-developers.com/showthread.php?t=2450045

First, you need to get ADB set up on your computer.
In Linux it's pretty easy.  Something like running
# apt-get install android-tools-adb
or downloading and extracting a directory.
Find your partitions.
Run something like:
adb shell
cat /proc/partitions
There are other options in the link for how to find and identify all the partitions.
Copy the data
The dd tool should be available.  You can run something like
dd if=/dev/block/mmcblk0p9 of=/sdcard/image.img

Unfortunately, I have two problems with this. The first is that the permissions on partition devices might require root access. The second is that the Kindle Fire HDX and many other modern devices that don't have "USB Mass Storage" also don't use SD cards. So there is no easy location to write the image you want that isn't already used for something else on the device.

I'm trying to find a way to mount network devices or transfer data over USB between the device and computer (adb push and adb pull won't do what's needed as far as I can tell). I'll update this if I can find a good solution. Otherwise I'll ask some other questions about it.

Edit: This page has a great description along the lines of what I have above: http://www.df.lth.se/~jokke/androidfilerecovery/

As noted below, root is necessary, but there are usually lots of ways to get that easily. Unfortunately, I was working with the Fire HDX 8.9. Halfway through my copying data to an image file, the thing auto downloads an update to 4.1.1. Next thing I know, root access disappears and I don't think there's an exploit out for it yet. I probably lost any recoverable data after the update was written to the internal storage anyway. I'm so frustrated with Amazon lately...

This line: adb pull /Dev/block/device-by-name/userdata data.img should work. I didn't test it out but should be close.  This would pull the whole image which you could flash or maybe push later in the process of restoring. It only works if you're rooted. I won't work when you aren't. Permissions error. I am guessing if you did fastboot with TWRP and not rooted, if you get decrypt working, you can copy the image that way. I am avoiding rooting right now. Seems to be more stable with Android 10


Google play paid apps not working on daughters tablet My daughter received an ASUS Memo pad 7 for Christmas, I set myself up as the main 'owner' and added her as a user and set up her own separate gmail account so she can download apps, etc.

I downloaded several free apps for her on her user profile that have all worked fine, however the paid apps that were downloaded on her user profile using her google account will not open. As soon as I touch the icon the following message appears: 'unfortunately Temple Run: Oz has stopped' with the options: 'Report' or 'OK'. All apps whether paid or free work fine in my user profile on the device.

The only reason I can think of is that I used the same credit card that I use on my own Google account. Ive paid for two apps; Temple Run: Oz and Minecraft PE.

Can anyone help?

you say you've set it up as you being the main owner, maybe that's what's confusing it, can you buy top-up cards, so that your daughter can pay in her name instead, & try doing a restore back to factory settings, &  THEN downloading the games. lori


How to pay for my kids apps? Here is the story. I have two kids (5-7 years), they have their Android tablets... and I have the credit card. I have created two google accounts, each for one tablet. I want to buy apps for them, but I don't want to enter any details of my credit card to their google accounts, because the theory is that they will be using these accounts in future to communicate, browse etc. I don't want them charging my card without my knowledge.

A while ago, when buying something in the google play store, I was able to select between one of the tablet accounts and my own account. I then had to enter the password to my own account and was able to install the given app. Now this seems no longer to be possible.

I am lost. I am a 40+ year old Un*x user and I am confused and frustrated by Android. Is there a way of buying apps for my kids that is safe?

There's a much easier way, but it may not be supported in all countries: Buy them each a Google Play Gift Card, and attach it to their accounts. They come in different "sizes", so you can limit the amount they can pay. No identification stuff connected to the cards, and once they're used up there's no more use for them (of course, you can buy the next one).

Another positive aspect: you might decide to let your kids use them themselves. The danger is just as high as the value of the card (though content might pose a risk). So it's like "pocket money" for learning "monetary responsibility" :)

You get two choices when you accept to buy an app on the device you want to install app on. Pay or send URL for payment to whoever. So send URL to yourself or whoever is going to pay via email which will auto pop up when you select... Send URL... .. I send to my Gmail account then click link on pc or phone and follow instructions to pay . Easy


How to rotate display output but not touch input I recently bought a Tolino Shine. I wanted acces to the underlying Android System, so I opened the device and enabled adb. Now, the display shows everything rotated by 180 degrees. The touch input is still unrotated. It bothers me that input and output are not in sync.

I should mention that there is Android 2.3.3 installed on the device and I successfully rooted the device.

How can I rotate either display output or touch input?

Certain apps fail to update from Play, while others work I have been having this issue between ROMs, as well as between connections. I am currently running ParanoidAndroid 3.94 (Android 4.3) with franco.kernel 3.0.89. Other apps consistently update fine. The error I get is

  Update for "application-name" could not be downloaded due to an error. (403)

I have eliminated the following factors:

Network issues (issue persists with two separate Wi-Fi points, as well as mobile data)
Google Play cache issues (I have cleared cache and restarted the Play app)

If I "sacrifice" one of the apps that do not work and uninstall "TuneIn Radio Pro" from Play store — I am then also locked out of actually getting the app back on my phone. The button in the Play store says "Install" (note: not "Purchase", so my existing ownership is recognized), I click it and "Accept", and the app even starts downloading! However, after the installation starts, I get the following error message:

  Error: Package file is invalid

Now, I am able to get all of these apps just fine on another device I have (Nexus 7), so I appreciate the fact that there is something up with my phone that causes this. However, I am not certain that it has to be something with the phone as it can also be something on Google's end not handling my dual accounts very well and therefore throwing the 403 (Forbidden) error when I try to download an app I actually own.

This was solved by going into /data/data/ and finding the appropriate folder belonging to the failing app. I found one with "swiftkey" in the name, deleted it, and following that the update worked just fine. Most likely, the app installation was failing in the background with INSTALL_FAILED_UID_CHANGED due to the app being restored with TitaniumBackup, as detailed in this answer.

So, in short, this seems to be an error caused by the UID changing between installs and Google Play throwing a fit, and it's solved by making sure app data is removed.

Delete the Application from your Device
You are installed the same application in your device, after that you are trying to install the same application from Android market

Please delete the pre-installed application from your device, then try to download from playstore, it will work 100%

Alternate scenario is: Please change the package name of the application, Your application will work fine.


why do all sound apps get  bluetooth button events, all at once If i have my phone (thunderbolt cyanogenmod7/2.3) connected to a bluetooth stereo and i hit the play button on the stereo, music, pandora, Subsonic, and Audible all start playing at once. pausing pauses all of them.

is there some way of controlling what apps respond to the buttons?
is there an app to filter button events?

The app Media Button Router is just what you are looking for. The app allows you to choose the media app you wish to control with the Bluetooth forward/reverse buttons using voice prompts.

The app doesn't work perfectly with all media apps, but I find that by playing with the settings you can usually overcome problems. But when it works it is magic!

Check to see if all of those music processes are running. I would assume they all listen to play/pause events while active, maybe verifying that all but one are killed could get a response from just one.


Samsung Galaxy 3 incoming call problem Most of the time I receive incoming calls for few seconds, then it shows as missed call while my caller listens full ring, leading them to thinking that I didn't pickup the call. I checked all the settings but couldn't find anything. This happens especially when I connect 'vodafone' sim card. I didn't have this problem with other sim cards. My handset is Samsung Galaxy 3 (GT-I5801).

remove true caller or similar app from ur cell, restart the phone it will be ok...tried my self.


Moto E Not Starting Properly After Changing runtime to ART I have recently bought a MOTO E and it's working cool. Then I have enabled Developer options and changed my runtime from Dalvik to ART. Afterwards I restarted my device. I got the message saying Android is upgraging. After completeing the process I got exceptions like

unfortunately the process com.android.phone has stopped

Please help me how to get out of this problem. I am getting that message for around 10 times and mobile restarting once again.

/data/property/persist.sys.dalvik.vm.lib contains the name of the runtime library you wish to use - libart.so or libdvm.so. So, you can switch back to Dalvik like so:

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

I know that this thread is old, but this may help others in the same situation. My mobile is a LG G2 Mini (D618) rooted with Kingo. After I changed it from Dalvik to ART, it took a long time to reboot, while optimizing all the apps. But then, when the UI showed up, I couldn't do anything because several error messages appeared in sequence. After a while touching OK for each message, the mobile would reboot and start it all over again. In fact it rebooted even if left alone.

I re-flashed it with the stock ROM (with the no-data-loss option) but nothing changed other than it becoming unrooted again. Also tried to access it with an ADB Shell but I kept getting an authorization error. Then, after rebooting it around 30 times, it reverted back to Dalvik by itself, and everything was fine again!


tts or some other notification sounds not playing at right time when screen is off tts stops reading the next paragraph when screen is off , notification sounds from some apps don't play while screen is off.

Android suspends its tts service when screen turned off.


How can you prevent a Kindle Fire from auto-mounting on a Mac when you plug it in to USB? I've got a Kindle Fire and I like to plug it in to my Mac to charge up (and also to do some development.)  It works fine but it is annoying to have to unmount it every time.

Is there any way to prevent it from auto-mounting when you plug it into USB?

Check Your Phone it should show some setting named 'Connect to PC'. Change the "Default connection type" to "Charge only".

There are some USB Cabes that don't support enough power to change data, so they just charge and don't mount. But I don't know how you could find them. Try google for it.


Seeing the full text of a long notification I've got a notification on my phone where the length of the text exceeds the width of the screen and it doesn't wrap, just wanders off the edge. How can I see the full text of the notification?

I've seen a suggestion here that long pressing for ~5 seconds shows it however all this does is bring up the App Info menu. Maybe on older versions of Android that didn't have the App Info menu this worked? Ideally looking for an answer that works on Ice Cream Sandwich and above (since I think that was when the App Info came about?) but I have a Nexus 4 running Jelly Bean 4.2.2 phone.

Here's the notification that I received. Hypothetical: Why did I lose data connectivity? What did I do!?!

In 4.2.x Jelly Bean you can pinch-zoom or two-finger glide in order to toggle between base and expanded [notification] layouts. Not all notifications can be expanded, however. The next time the notification appears try using two fingers to "pull" the notification down into an expanded layout.

use: Notification.Builder(context).setFullScreenIntent(pendingIntent, true),
manual to make the notification to show full screen


Offline YouTube feature suddenly gone Till yesterday noon I was using this offline option, but from yesterday night I can't get the offline option. My YouTube app is built-in app, will that make any difference?

I even tried re-installation of the app, but I still didn't get it. Help me to get my offline option back.

I found that my YouTube was updated on 18th September 2015. But since I used the offline option since yesterday (21st September 2015), I think the version is not the problem.

offline mode is for youtube red users now


Problem copying files from PC to Galaxy S3 (slow or frozen) I have a lot of difficulty copying files to my Galaxy S3. My goal is to sync my music from MediaMonkey to my GS3. When I connect the phone, the computer sees it but the connection is incredibly slow! And it is the same thing if I copy files using Windows Explorer or MediaMonkey. The files start to copy, it takes maybe about 1 minute per song, and at some point it will slow down, then stop to progress and freeze.

I made sure I was using the stock USB cable provided with my device but I also tried 2 other cables with same results. The last thing I tried was to clear the cache partition then reboot. I also tried different USB ports on the PC (USB2 and 3, different controllers).

I'm out of ideas.

You can use Dropbox and other cloud based storage, very useful for moving files.


On my Note 4, even when I set the lock screen to fingerprint, if I turn it off and then on, I can unlock it by swiping. Please advise I set the unlocking to fingerprint. I set 3 fingerprints. I activate them. Then I can unlock my phone by swiping. What is the use?

Often there is a settings which sets a Timout for a locked phone. By default I think it is set to 5 seconds. That means, that when you turn your screen off your phone waits 5 seconds before activating the lockscreen security. Try searching the settings for this timeout setting.

How to enable silent mode during calendar events? I'd like to disable all notification sounds whenever there is a current event in Calendar. How can I do this automatically?

Llama will let you do this, and it is free (Tasker costs money). It has many of the features as Tasker and Locale, and it can even use Locale plugins. I have grown fond of this app and have set up many automated events.

To do this in Llama, you create two events and two profiles.

Profiles

Create a new profile and name it something like "No Notifications". Uncheck all of the volume options except for Change notification volume. Set the volume level to 0.
Create a second profile and name it "Normal". Again, uncheck all volume options except for Change notification volume. This time, set the volume level to whatever you want, like 5/7.

Events

Create a new event.
Under Actions, click Add Condition and select Calendar Event. Use the defaults.
Next, click Add Action. Select Profile and choose your silent profile.
Create a second event. This one will be the opposite of your first event, so change the condition of the calendar to "Event finished/Not current event" and set the action profile to your normal profile.

The developer of Llama is still working on it and adding new features, and you can get details here.

I also wrote an app Polite which allows you to pick keywords in your calendar events

Why is the SSH server not working on Android 4, are the ports being blocked? I am having difficulty ssh'ing into my new Android 4 (Samsung Nexus) phone.

I have installed various SSH Servers but in in all cases the ssh connection just hangs (i.e. I don't get as far as username/password).

As an example, using SSHDroid:

Verbose SSH log from my linux box :

joel@pepper ~ $ ssh  -p 2222 root@192.168.1.65 -vvv
OpenSSH_5.8p1 Debian-1ubuntu3, OpenSSL 0.9.8o 01 Jun 2010

debug1: Applying options for *
debug2: ssh_connect: needpriv 0
debug1: Connecting to 192.168.1.65 [192.168.1.65] port 2222.

The output from nmap does not look right. A status of filtered on the port implies a firewall is blocking it:

joel@pepper ~ $ sudo nmap -sS  192.168.1.65

Starting Nmap 5.21 ( http://nmap.org ) at 2011-11-20 21:29 GMT

As far as I know, the default ssh port IS 22 on Ubuntu, just as "Lie Ryan" pointed out.  You might want to check your sshd_config files on your PC, if you want to take a look at this article, it specifies on how to change the default ssh configuration on Ubuntu--as well as the official documentation.  Beyond that, check your current firewall settings, you might be able to open that specific port temporarily to ssh-type service if you want to confirm that it's not something else.

Aside from that, it seems to me that this question was asked more than 6 months ago; if the OP hasn't figured it out by now, I doubt he'll be interested to pursue it further.  I suggest either accept an answer, provide update on the situation since, or perhaps close the question.

EDIT: depending on your android ssh-server app, and whether or not you're running it with su privileges, this is from the "QuickSSHD" website:

  non-root users are limited to ports < 1024 and the QuickSSHd application user, which CAN read and write to the SD Card.

The default ssh port is 22 not 2222, perhaps that's the root cause of the issue? Try connecting on port 22.


adb push: sync but not copy adb push seems to push everything into the dest folder regardless of their changed/unchanged states. So it wastes a lot of time. Is it possible to sync rather than copy (i.e. to rsync rather than cp)?

I see adb has a sync option, but I'm not quite sure whether it's relevant or not.

You would use adb push --sync, for example:

adb push --sync /home/abc/ /sdcard/abc

from adb --help:

file transfer:
 push [--sync] LOCAL... REMOTE
     copy local files/directories to device
     --sync: only push files that are newer on the host than the device

but it seems that this function is available for relative newer ADB version such as version 1.0.40.

When running adb without any commands, you get a list of possible commands, and here it is:

adb sync [ <directory> ]     - copy host->device only if changed
                             (see 'adb help all')

Looks pretty relevant to me :)


Micro SD card not usable on phone I installed a Micro SD card on my Samsung Galaxy 3 phone. I had a few dozen songs on the card and everything was working fine. Then I shut down my phone, removed the SD card, hooked it up to my PC and loaded the card up with a few hundred MP3 files. When I reinstalled the SD card on my Android, things went wacky. I can see the SD card icon but when I go to Settings > Storage, the only option I see is the "Mount SD card" choice. When I click it, I get "SD card safe to remove".

Bottom line is that the card seems unusable on my phone but works fine on my PC. Ideas?

I've had this problem numerous times and this is how I fix it.....

Take the SDcard and insert in card reader on PC. Use a partitioning program such as GParted, which is open source. Have it scan and fix errors on the card. Using just the PC to scan and fix errors wont work right for your problem. Put it back in your Samsung and enjoy.

Android like fat32 filesystem and fat32 like <4gb sdcard Windows like ntfs system but also familiar with fat32. My advice, format your SD with fat32 and remove it safely turn of your device mount your SD and power your device wait after boot and let us know


How do I enforce charging only on USB and disallow data? The US Federal Trade Commission now suggests consumers driving rental cars not plug in their mobile phones using USB, due to security concerns.

I understand for the security of my phone and data the physical solution is best; there is no way data can be transferred though the cigarette lighter, but this requires carrying additional hardware when traveling.

Is there a way to disallow data transfer over USB within Android? My primary concern is with unrooted Android 7.0 Nougat, but I am actually interested in prior Android versions as well.

I am aware of the "Use USB to" menu that shows up under notifications with  the following options:

Charge this device: Just charge this device
Supply power: Supply power to the other connected device
Transfer files: Transfer files to another device
Transfer photos (PTP): Transfer photos or files if MTP is not supported (PTP)
Use device as MIDI: use this device as MIDI

I am able to use USB debugging while "Charge this device" is selected, which is definitely sending data over USB and is in conflict with the description. Does this mean only explicitly allowed devices can send data over USB in "Charge this device" mode? Or are there other exceptions as well?

How do I enforce charging only for USB connections like a rental car and disallow data transfer?

First, don't leave ADB enabled except when you need it,  even though you have to authorize any device that uses ADB, as good safety practice... Other than that, Marshmallow and newer Android do not allow file transfer or other data transfer without authorization on a per connection basis.

In Marshmallow or newer, I think this is generally an unwarranted concern and usb connection in rental cars can safely be used. TBH, I doubt any legitimate rental company car is of concern at all.


Galaxy Tab P1000 shows a phone  PC symbol and is not responding after flashing I was flashing my GT P1000 and the power went down, then on the galaxy tab screen i see an image of a Phone ! PC and nothing i can do to reboot it or connecting it to the laptop. Its dead.

please help

The best you can do is power off the device completely, but do nothing for now, head over to samfirmware and download the appropriate ROM for your region.

Once you do that, refer to the instruction on using Odin.

You should have the PIT, and the MD5 file, and also the CSC file set up within Odin.

Then press and hold the VOLUME DOWN button, and then briefly press the POWER button, the device should go into download mode. From there Odin should detect the device, then start flashing as normal.

Disclaimer:

I am not responsible, please double check to make sure you have the right check-boxes ticked within Odin. If all else fails, refer to the XDA forum

Another route:

If you cannot get into Download mode, try the hard reset - that is, ensure the tablet is powered off completely, hold the VOLUME UP button, and then briefly press the POWER button, the device should hard reset itself.

And try the above again.

heyy i got an answer .

go to youtube and search for Update P1000 to gingerbread

Select Vio's , and download the file

Watch the video.

i had the same problem too.


Music player that utilizes ReplayGain tags and can scrobble to Last.fm? Is there a media player that can read ReplayGain tags from the music files and adjust play volume accordingly? Also it will be appreciated if it can live scrobble playing tracks to a chosen Last.fm profile.

As a bonus: Can it display currently playing song to a bluetooth handsfree with screen, like SE MW600?

Thanks in advance.

Winamp supports ReplayGain in its desktop versions, so the Android version might also support it (I'm not positive, but it seems reasonable). It definitely does support scrobbling, though I've not used it myself. You could give that a try and see if it fits your needs.

DeaDBeeF supports replaygain and many file formats. Also has a nice interface, but its integration with the standard music library is not as good. Still, well worth a try.


Easy question: How do I search for apps on my S3? I know (N00b) but I see the Google search bar for performing internet searches. But I don't see where a quick search for my phone's content is, like you would find on an iPhone by moving to the search screen. (Which searches through all of the phones content-contacts, apps, email, etc.)

Press and hold the menu button (button to the left of the physical home button). It will launch google now and if you enter the first letter of the name of an app it should start listing those apps, at least it does it on my galaxy s3.

If you pinch inwards on the app list then the app lists minimize and can be rearranged.


Google play store opens when leaving contacts On my S5, when I am leaving my contacts (e.g.after having called some one) the Play store opens always ever, showing me the App 'Next launcher 3d shell lite'. This is quite a while now and I can not remember when it starts. Since about a month now it even starts when doing other things like checking which apps are still opened through the button left of my home button. Anyone got an idea how I could get hold of this problem ?

I think it is caused by some third party app ,to confirm this call someone in safe mode and see if playstore is started.

If the problem is not in safe mode ,It is confirmed that it is caused by a third party app.

Now you have to guess which app is causing this issue but rather than guessing you could see running apps in process status which is located in developer options.

Or you could check application manager  and in running tab see any unknown/strange/untrusted app.

After un-installing that app I hope your problem will be solved.

Hope it Helps.

The app causing the issue was "Next Honeycomb" which is a nice live background for my phone, not anymore though. I erased it and it now doesn't do this again.

Does Samsung galaxy tab pro 10.1 support exFAT on the SD card? Does this tablet support exFAT file system on micro SD card? Can this tablet recognize micro SD card formatted with exFAT file system?

Yes, as indicated on the user manual. I'm currently using a Sandisk Class 4 32GB formatted with exFAT, works just fine. Stock ROM, unrooted.

Just format everything to FAT32.
Your mobile,flashdrive and PS4 all just format to FAT32.
Format everything to FAT32 the best.
For example:You use FAT32 files from PS4 to FAT32 flashdrive(5GB),then you transfer the files in your flashdrive to my mobile(ExFat and FAT32) driver.
The transfer will be exactly 5GB,because FAT32 and FAT32 has no side effect of expansion of files.
Beside,adding FAT32 to your mobile is very cheap.
Just pay $1 to $2 and you will have no issue in the future.

It is very likely that Samsung Tablet use EXFAT,because it exceed 32GB in it's memory slot.
I am refering to Memory card.
To prevent expansion of files,I add FAT32 to my Samsung Tab.
Beside,it is so cheap.

Pay less than $2 and you can forgot about all worries.
Let say one day........
You tranfer 5GB of files to your flashdrive and then transfer it into your mobile,which is EXFAT.
But,the EXFAT expand your files to 10+GB.
When you tranfer the files to your flashdrive and then transfer it to your PS4,you can't save all the data to your PS4.

http://forums.hardwarezone.com.sg/hardware-clinic-2/exfat-take-up-more-space-than-fat32-4746802.html

Just set everything to the same format and if it is less than $2.
Just buy the add on.

In the future,you don't need to worry which porn video in your mobile must you delete.You don't need to delete some of your PS4 games to make space for your data.


Why is "Android OS" uploading so much data? After switching from my Nexus S to a Nexus 4 I noticed that my phone was transferring huge amounts of background data.  Like 70 MB in 15 minutes.  As my data plan only allows 300 MB per month I was not amused.  Even when connected to WiFi, it often (but not always!) was uploading tons of data.

According to the "Network Usage" the culprit was "Android OS".  So I tried to limit the background data of it only to find that "Android OS" seems to be the only "app" which doesn't offer this option.  Great.

Well okay, that's what firewalls apps are made for.
I configured AFWall+ but that only cured the symptom not the cause.

Next I redirected the traffic to a laptop with a WiFi card and used the usual tools (tcpdump, wireshark) to analyse the traffic.  Result: many many uploads to some Google servers but SSL encrypted so no chance to see the contents.

I kept investigating and found this very interesting article on Android data usage.
Apparently Google has began expanding its cloud-based backups of the phone settings so that it now also does backups of the data of some apps.  So, I turned off "Back up my settings" in the Privacy settings and whoopiedoo, the sending stopped and the data traffic returned to a normal amount!

There is a post in a Google forum with similar experience: Something within the Android System—maybe Backup—is using up all my data allowance.

I started looking in the Android documentation and found that there is such a thing as "Android Backup Service" which apps can use to backup their application data to the Google cloud: Data Backup

And there is even an CLI utility "bmgr" to interact with the Backup Manager.

But I cannot find any information about how the phone owner can find out which application is backing up which data, or how to influence or stop this.  I'd be happy to use the backup service—it saved me a lot of time when switching to my new phone—but the way it is implemented now it's definitely unusable.

After talking to my former coworker and Android expert Izzy who was clueless too, I decided to post this issue here as—like he said—I will find the best experts here.  Well, let me know if you have any idea about this.  Any hint is welcome!

The list of applications with backups as well as how much space each backup uses is on your Google Account Dashboard under "Android Devices".

Unfortunately, there isn't, I believe, any way to control it other than turning it on or off entirely.

Android OS also includes the YouTube data or any video data which you have viewed online using browser/YouTube. You must have watched equally that much amount of videos online from your device. When you browse in the YouTube app or browser only browsing data is recorded by respective apps the actual data streamed for video is recorded under Android OS


I have factory reset my phone, there is almost a gb of app installation space My 16gb SD Card got corrupted today, so I lost all of my data as I was unable to format it.

The real problem is, I also factory reset my phone just now, so there is 16gb internal memory amd 1.5gb app installation memory, out of which only 400mb is used.

When I attempt a download from Google Play Store, they get downloaded completely however while installing, it gives an error message "Insufficient storage". I'm fed up with this issue, I don't know what to do.

Let me also tell you, my SD Card data was encrypted, so I was unable to format it, should this be a problem. However, I factory reset my phone and now internal memory can do nothing with it.

My phone is Intex Aqua Power HD running Android 4.4

Ok, try to connect your SD Card to another device and Format/copy out your important files.

If that does not work, use a card reader to access your SD Card on a Windows device and SCAN as appropriate.

It could well be a minor threat and your PC anti-virus could solve.


Making volume controller more fine My Sony Xperia has buttons to control the volume as most of other smartphones. The control is rather coarse, there are only 8 steps including max volume and silence. Especially for use of (Bluetooth) headphones this is silly coarse.

How can the volume adjustment more fine? I would like to have e.g. 32 steps here.

Edit: The device isn't rooted and I don't plan to do so.

No way to do so if your device isn't rooted.
Every app you find for the same will require root access.


My android can't log in to Wifi networks with Captive Portals It used to work about a month ago.

Whenever I went to the mall, or this one coffee shop, and also at 7-11 outlets, I would get the notification "Sign in to wifi network", then I get redirected to their login page when trying to visit any webpage in my browser, I sign in, and I can connect after.

But I have been playing around with my android in the past month

installed AFWall+ to allow only Opera Mini to connect on 3G
installed ProxyDroid to view the traffic on one of my games (and to get infinite gold lol)
added Charles Proxy certificate
installed and uninstalled XPosed framework
other stuff

And I just recently realized, I never get the "Sign in to wifi network" notification anymore, and I just get a cannot connect error on the browser.

It seems my phone's ability to sign in to captive portals has been completely broken somewhere along the way. It used to work 100%, now NONE of the places work.

Is there any way I can fix it?

In afwall there should be a program listed as CaptivePortalLogin. Give that program permission to access internet.

For my xperia phone, stamina mode was the culprit. Disable stamina mode and everything works fine.


Play Store not installed error I had the Play Store App on my Android running Jellybean.  The icon still shows on my main screen, but I can't find it in my apps folder.  When I tap the icon I get an App not installed error message.  What happened to it, and how can I get it back?  Apps don't download anymore.  I get  message that an app will be installed soon, but I am never able to find it.

Who is the manufacturer of your phone? If the phone comes with android per-installed and its a licensed one from Google, Play Store should be installed and working in it. In that case, you should contact Customer Care and get your phone flashed with the Stock ROM.

I had the same issue and it got solved by itself. Play Store was just updating itself to a newer version, so give it a couple of minutes, say 3-5 minutes.


How can one move the position of the application inside the launcher? Possible Duplicate:
  How can I arrange the applications on each page of my app drawer?

When I click on the launcher icon (shown on the bottom right corner of the LCD screen as illustrated by Picture A), it will display the list of applications which are installed (as shown in Picture B).

However, I notice that when one boots up the phone, some of the applications are shown and later when the SD card is fully mounted, the rest of the applications are then shown inside the launcher.

So, I was wondering if it is possible to move the location of the applications inside the launcher to another page (assume if there are pages for one to move the applications) or other location in the same page.

Please note that I am not referring to the applications shortcuts or creating applications shortcuts onto the screen of Picture A.

Picture A

Picture B

It looks like you are using TouchWiz.  If so, go to the App Drawer (Picture B).

The directions below will vary slightly based on the version of TouchWiz you are running.

Hit the Menu Button, and select View Type, then select Customizable Grid.

Then, hit the Menu button again, and select Edit.  In this view, you can move your icons in the App Drawer.

For what it's worth, you can also edit your dock icons.

Apps in the App drawer are sorted either:

Alphabetically
Latest installed last
Latest installed first

As such, there is no way to move apps in the App Drawer, unless you download a custom home screen app that supports it.


On screen soft mouse? Is it possible to have a touch control of the mouse cursor in Android instead of the use of a hardware mouse?
Maybe something like the soft keyboard?

As Liam W suggested, have you tried the any of the developer options? On at least 4.0 (ICS) and higher (and perhaps older versions, someone else will have to verify) in Settings > Developer Options check out Show Touches and Pointer Location (screenshots and short descriptions here). Neither are exactly what you're looking for, but perhaps you'll find them useful.

I really wondered why does not exist useful app for tablet or other wide mobile screens like touchpad and ro
cursor. I found that finally. It is so tough to excute that function. Unfortunately, It is only be used for rooted device but if you have that. It will be very useful app. It is free app, I recommend this app for tablet users and if it is not functional please see the app description. first, you must have rooted device, second if your android OS 5.0 or above , you have to download selinux mode changer in search google. set permissive and reboot your device. Have a good day.
If you want to find this app, google keyword search - easy touch auto clicker. and you will find the shape of arrow.


Forwarding all mail in Gmail using using android app. My father, nearly 80, has forgotten his gmail password and cannot recover it. However, it is saved on his android phone so he can access it on his phone, but not on a laptop he wishes to set up. I suggested he create a new gmail account and autoforward all mail from his current gmail (via his android phone) to his new gmail account.

How can he do this from his android gmail app? I can't find a universal forwarding option for mail to the account.

Unfortunately, there is no option like this in the gmail app. You would have to log in on the website to change it, maybe the login is saved in the chrome app, so you can set up the automated forwarding there.
You can even set up another e-mail in the accounts settings of your google account, where you could recover the mails. Just go to accounts.google.com on the phone and there you can set up a lot.
But only, if the password is saved.

The only solution if the password is not saved would be:

forward every existing mail to the new mail account
create an automated answer for the old account with the new mailadress inside
keep the old account still in gmail in case of any important mails
transfer the accounts, which are linked to the old mail adress to the new by entering a new mailadress in the respective accounts (i.e. banking, news, amazon and so on)

You can now use gmail multi email forward to do this


Is it possible to root the Verizon Samsung Galaxy S5 (SM-G900V) on Android 5.0 Lollipop? I had root on 4.2 previously, but the update lost it, and with it my ability to use Sixaxis, AdFree, some features of NFC Tools and Tasker and Xposed modules.

I have searched, but it does not appear on this list:
How do I root my Android device?

I also saw a similar question here, but this is the AT&T version, not Verizon:
How to root the SM-G900F Android 5.0 without tripping KNOX?

Towelroot doesn't work (just tried) and the SM-G900V isn't listed here: https://autoroot.chainfire.eu/

Anyone have any experience with this?

Hi there is a way out but it requires a bit of home work.

Towel root can only root Android KitKat so you've to downgrade to Android 4.4 and gain root access using Towel root.

Later you can upgrade to Android Lollipop 5.0 without loosing the root access.

If you like the idea here is the reference link to the guides given on the Xda developer forum.

How do I enable the MTP functions on my Nexus 5? When I plug my Nexus 5 phone into my Windows 7 desktop, I see the Nexus 5 device in the file Explorer, but no files. I am sure this is because I need to enable the feature from the phone side, but I can't find it in Settings.
In Device settings, I have "Storage and USB", but all it seems to contain is a way to see on the phone how much storage is used by each App. The three dots in the upper right corner only open up to allow me to look at Help.

Where is the setting I need to change?

There should be a notification in your notification drawer saying USB charging this device tap on it and select Transfer files.


Location of saved images from Facebook Messenger app I don't use Facebook app (browsed on Google Chrome), but I use its Messenger app. Where can I find the saved images from Facebook Messenger app?

Facebook Messenger saves photos to $EXTERNAL_STORAGE/Pictures/Messenger.  That variable depends on your device, but on mine it is /storage/sdcard0 which is also pointed to by the /sdcard symlink.

If you are using Chrome Browser then you can view it in your Downloads folder. If you are using Facebook Messenger App then you should be able to view the photos in you Gallery app. Internally when using Facebook messenger, it hides the downloaded photos inside the system. You have to have a rooted phone to access those hidden files. Its in the hidden root directory,

data/data/com.facebook.orca/cache

you have to copy the folder to a directory and rename the .image files to .jpg files.


Gallery thumbnails locked I have a problem with my gallery thumbnails for a few days now. Thumbnails are generated in the .thumbnails folder but they are not displayed in the gallery, there is instead a picture with a lock.

How can I solve this? I have already tried to clear data but it didn't work. It seems like there is a broken permission in the gallery application.

I have exactly this problem. There is no gallery locker on the phone. I have removed the thumbnails from the DCIM directory, and Android has re-scanned the SD card and created three sets of thumbnails: Camera, Whatsapp and Wahtsappvid. But when I view them in Gallery, I get the same symptoms as above, with each thumbnail showing as above. If I click on one of these 'blank' thumbnails, the picture displays ok. If I use MediaSee it seems to display all the pictures as thumbnails.
Perhaps of interest may be that the picture above looks like a Motorola Defy Mini phone, which is what I have got. Sorry if this is the wrong way to ask this question, but this is the only post I have seen which shows the problem I have got.


Android Launcher Loading Problem I'm desperate, otherwise I wouldn't post this long type of post on this forum, cause whenever I have a problem, I just search it on Google and 99% of cases I find the solution, but this time, I'm helpless. I would really appreciate if someone has a solution to my problem,

I have a Infocus M2. It is an awesome phone, I'm really satisfied with it. I have it for 1 year now and I have never had a problem, everything worked perfectly (and is still working), but for 7 days something keeps popping up: it doesn't matter if I'm in a game, or on the internet or am I doing something on the phone, a black screen with text "Location service" and after that a white screen appears with a little text "Launcher loading..." and a circle that is loading, and I have no idea what is that. I can't do anything, I just have to wait like 1 minute for it to disappear. After that a new app automatically start installing from Google play store.

All this problem started when I install a free app "Task bucks" from Google play store. and this app automatically install a app "Key Chain" After that I just loose control over my phone. Whenever it connects to internet it start downloading apps like DU Speed, Battery Doctor and some those apps automatically install that I uninstalled 1 month ago etc. It's really frustrating. Also, this happens, like one time in 1 hours. I really hate it.

I have to mention a thing:

Some times After the white screen disappears, Google App Store opens, at a shopping app called "Ali Express" (like it wants to install it or something), I had it installed only one time, but I uninstalled it 6 months ago.
Key Chain does not remove by restore factory setting. that is automatically installed from Task bucks

Note: I know one Key Chain is default app but my phone has 3 key chain

I have Attempts following steps to solve my problem:

Restore factory setting and deleted all third party apps 2 times but problem is still.
Run up to 4 antivirus apps but no luck
Change google account password
Boot my phone in safe mode and clear cache, clear defaults of some apps like: launcher, key chain, location service etc. and Reset app preferrnces.

I'm sorry for the large post, but I wanted to be as specific as possible. Thanks in advance.

If your phone is rooted you can use Stubborn Trojan Killer.


Android 2.2: Avoid disappearing of home shortcuts to apps into SD card. Restore app list items I'm using a Samsung Galaxy i5510. The space in internal memory was just about to finish so I decided to move some apps to the SD card. After I did it a lot of the apps moved (not all of them) disappeared from the application list. Also did the shortcuts from my desktops.

I don't think this is a problem with the SD card because the applications are still installed (I can see them in apps management).

Thanks for your help!

Update

Tanks to @GAThrawn's answer now I know that it is expected to disappear the home (desktops) shortcuts when the SD card is unmounted. But it is not expected that they disappear from the application list. So the questions:

Is there anyway to recover the icons in application list other than reinstalling all apps?
Assuming that this wont happen any more and will only disappear from the home / desktop. Is there anyway to avoid that? I would like to have my apps in my SD card but with shortcuts.

The apps will disappear from your Home screen if your SD card is unmounted from the phone for any reason, they won't automatically come back on their own.

The most likely reason is that the SD card can't be mounted to both your phone and your PC at the same time, so if you plug your phone into a PC, and your SD card is mounted as a drive so you can copy files to and fro, etc then that dismounts the card from your phone temporarily and you'll lose the home screen icons.

The apps should still be in your Applications list and you should be able to add them back onto the Home screen the same way that you did it when you installed them.

This is a combined limitation of the way that the Android OS handles SD cards, and the way that most home screen launchers (like Samsung's TouchWiz that you're using) cope with apps moved to SD.

I loaded Ram Booster Pro for this problem, and after letting the phone boot up, click "boost" in the app. With one click it clears your RAM. Android Lollipop doesn't add this feature, so task manager is of no help. When you go back to your home screen you will see your app icons as you have placed them.


What is the fastest way to transfer huge files beween two android powered devices? What is the fastest way to transfer huge files (e.g. 500MB) between two android powered devices? Bluetooth? WiFi direct? Beam? or maybe USB on-the-go?

There are many variables that affect the performance of each method you've mentioned.
Additionally there's also the necessary configuration and requirements that each device must have in order to have solutions like this working.
As requested, lets summarize and compare possible performances between USB; Wi-Fi and Bluetooth:

USB:
USB performance can be extremely low or very high, depending on the available USB version, which in turn, combined with the SDcard reading/writing speed on each device allows us to accurately measure and ascertain the transfer speed.
There's also the physical limitation of the USB cable length that for some scenarios becomes a limitation.

USB 1.0: 1.5 Mbit/s (Low-Bandwidth) and 12 Mbit/s (Full-Bandwidth)
USB 2.0: 480 Mbit/s (effective throughput up to 35 MB/s)
USB 3.0: 5 Gbit/s (625 MB/s) which is more than 10 times as fast as USB 2

Wi-Fi
Wi-Fi loses limitations like cable length, but then again we need to account for the 802.11 protocol being used, the signal strength and range to accurately measure results:

Wi-Fi Direct
Wi-Fi Direct, initially called Wi-Fi P2P, is a Wi-Fi standard that enables devices to connect easily with each other without requiring a wireless access point.
Here the communication is performed at typical Wi-Fi speeds for everything from file transfer to Internet connectivity. Essentially, Wi-Fi Direct falls under the same values presented at the Wi-Fi table (yet again keeping in mind that signal strength and range are the key factors for a good performance).
More about Wi-Fi Direct from Wikipedia.

Bluetooth
While we need to ascertain several influencing factors to determine if Wi-Fi is faster than USB, Bluetooth is with no doubt in last place when we speak about transfer speed. Designed as a proprietary open wireless technology standard for exchanging data over short distances, the maximum speeds are below the two concurrent options:

More about Bluetooth from Wikipedia.

Android Beam
Being a fairly recent technology, Android Beam allows users to transfer data between devices with Near Field Communication (NFC) capabilities.
NFC is even slower than Bluetooth (both short-range communication technologies) and is limited to about 20cm of range getting up to 424 kbit/s.
On a positive note, NFC sets up more quickly than standard Bluetooth and the connection between two NFC devices is automatically established:

Summary
Based on the specifications for each method and their respective version, my classification ordered by fastest-to-lowest would be:

USB assuming version 2.0, since 1.0 is way slow and outdated
Wi-Fi / Wi-Fi Direct
Bluetooth
Android Beam

If you don't have micro SD slot in both device, the alternate solution is to use any free cloud services. You can try Google drive or Dropbox to install in both devices under same user name and try to sync/transfer files in between.


Continuous clicking sound on the jack While the phone is powered on, and I plug something in the jack of the phone, I hear a continuous clicking sound, with the frequency of about 4 times per second, on the right speaker. The left speaker plays the audio as it should.
I don't have a mono device to see how it behaves with it...
The phone's speakers do not have this problem, or the Bluetooth headset.
The sound is identical, as far as I can tell, to the sound (almost?) any audio device makes when it's plugged in (and/or out?).

Phone: Lenovo A800
Android version: 4.0.4

The issue doesn't happen on my Nexus 7.
Happens with headsets, earphones, external speakers... Pretty much everything in the jack.
I chose to post the issue here because I have found various similar issues with other Android devices around the Internet, but no working solution.

Is there any known cause for this? Any solution..?

My brother just bought a new headset, and there's no clicking sound with it.
I looked at the jacks and there seems to be no difference.
Any ideas...?

Oh, I forgot about this.

My brother came to me and jammed the jack in as far as it could physically go.
The problem was fixed...

The jack component on the board inside is failing. Common problem. Fixable. Caused by overheating


S2 randomly restarting / draining the battery For the past month my S2, SPH-D710, Android 4.1.2, will randomly restart throughout the day.  I took the battery out for awhile and that didn't change anything.  Sometimes it happens when I'm looking at it, sometimes it will happen as soon as I plug it into a charger.. at which point it appears to completely drain the battery.  Seems to be only one of my chargers though.  Other charger is fine.  There is no clear pattern to all this.  These issues don't happen all the time.  Sometimes I'll go through an entire day with no problem. Warranty expired on the phone. I have never installed a custom ROM on here.  Is this something that might be fixed with a custom ROM or is it completely hardware?

Should be an hardware issue.
In my case was the oxidation of the motherboard cause by the sweat cuase i kept the phone on my arms while I was running.

Thanks everyone for your feedback.  In my case, there seemed to be no coming back from the dead.  Tried the rice, tried a new battery, tried a hard reset.  Nothing fixed it.  Ended up getting a new phone.


Auto delete messages from a certain contact Is there an app where you can add contacts or numbers to a list and anyone on that list will have their text messages auto deleted when they try to send you a text? Preferably one that can have this list be password protected.

When you block a number it automatically blocks all incoming calls and messeges from that number and also deletes all of the conversations you have had with them. This is so they won't be able to reach you at all and no matter what they do they won't be able to contact u. When you block a person it also earases their phone number. If you try to call or text them it also won't go through since you have already blocked them. There Will be no problem since neither of you can contact each other . It is the best way to go. Hope I could help.

I recommend you to try SpamHound SMS Spam Filter (for iOS https://itunes.apple.com/app/id1263185195, for Android https://play.google.com/store/apps/details?id=com.redwerk.spamhound). In this app, you can create filtering rules that block certain senders or messages that contain special text. All spam messages will be sent to the Junk folder, and you will not receive them. Hope, with SpamHound you will get rid of annoying spammers!


Streaming Amazon Instant Video in HD Is it possible to watch HD Amazon Instant Video (eg, Amazon Prime) on non-Kindle Android devices? (Galaxy Nexus with MHL adapter)

AFAIK, Amazon does not support HD streaming in the browser; this would require a native app.

Google Play does support this, but I haven't been able to find anything about Amazon.  (other than Flash streaming, which I don't think will do HD)

Just did it today on my Samsung Galaxy S3.

To stream Amazon Prime (or other Flash) movies:

Download Flash 11 onto your android device. You won't find it in the app market (Google pulled it this summer) but there are a couple different guides online. I used this one from CNET.
Download the Dolphin browser from the app market (other browsers MAY work as well if they let you change the user agent string, but Dolphin makes it easy and is the only one I tested successfully on).
Go into the Dolphin browser settings and set the "User Agent" setting to "desktop".
Login to Amazon and you can now stream Amazon prime/instant movies.

I used an MHL adapter to output the video/audio to my receiver and can now watch the movies on my surround-sound projector setup (though its not surround sound).

YMMV, as I'm not sure if this works on all android devices but it works on my S3. Good luck!

This worked until April 17th, 2013. Amazon changed something and Instant Video no longer works with even the latest versions of Flash for Android which can be downloaded from the Adobe Archive and side loaded.

The only option for viewing Amazon Instant Video that I have found is to download Puffin Browser. It decodes the Flash video on their cloud Servers and streams it to the browser on your device in some other format. Sadly, it is a little herkyjerky and the audio is sometimes out of sync and full screen is more or less broken, although you can zoom in to fill the screen.


Device not detected in fastboot | REALME 3 PRO I have device Realme 3 Pro. And I am trying to install TWRP. So, I downloaded In-depth test apk and got application reviewed. Then I booted into fastboot and device is not showing in device manager. I tried to add legacy device with google usb drivers. It said drivers installed but device starting failed. Error code 10.

It detected corrupted adb interface. So, I again updated same drivers.

This time device popped up in other devices and showed an error icon. So, I again updated drivers for the device. It says drivers installation successful.

But, when i double click on icon it shows no drivers are installed.

No matter how many time i update the drivers it shows no drivers installed.

Solutions tried

resetted my PC
resetted my phone
tried various ADB drivers for Windows
tried various ADB drivers for Android interface
completely wiped my PC
re-installed Windows (clean install)
updated Windows
updated all drivers present in Windows
updated BIOS
updated my phone to latest version

NOTE: OEM unlocking is ON. And usb-debugging is on too.

you can access your phone with fastboot command.
try fastboot devices in cmd and it will show connected fastboot devices.
you can see full command list with fastboot --help
if you want to install twrp, you need to enter the command:

but i think you need to unlock your bootloader first.


Repeating “Unfortunately Google App has stopped” error on Nexus 5 My Nexus 5 stated acting strange in the past few days.

Here's the short history:

A few days ago, I was prompted to install a new version in OTA update. Done.
Yesterday, phone shut off just like that by itself. When powered on, it has a message on a black screen saying "optimizing app x/150". When it was done, phone booted.
This morning: wanted to access Google Now, but it wasn't there - I couldn't flick to the left. Was prompted to 'reactivate' google Now, which I did. I should mention it was there after the OTA update.

Since then, every few seconds, and pretty much whatever I try to do, the error message in the title pops up. (side note: strangely, it says Google App and not Apps). Extremely hard to use the phone when every few seconds this pops up. Help, anyone? Thanks!

As it says "Google App", it's most likely the app named Google (no kidding: there's such one, just follow the link – though I cannot find it in Settings › Apps by that name). Just tried the one from the drawer, brings me to Google Now – which again matches the app you've got trouble with, as your question states: "wanted to access Google Now, but it wasn't there".

Going by the icon, the corresponding app in Settings must be Google Search – which again makes sense considering Google Now is part of that.

So I'd suggest you try to go there (in Settings › Apps) and clear it's cache. If that doesn't help, try clearing its data as well (same place). If that doesn't solve it, open the Google Settings app (not the general device settings, but the settings app with the "g" for "Google" in its icon – you can find it in the app drawer) and deactivate Now and Cards there. This disables Google Now, but solves the issue (as you've proven).

Hint in case you cannot reach out to Settings or the Google Settings app (e.g. if that pop-up reappears faster than you can tap somewhere else): You can clear all app caches at once by booting to recovery-mode and "wipe cache". No data lost that way. Another good hint in this context is safe-mode: if the troublemaker is a user-app, it won't be started here, so you can clear cache/delete data/deactivate/uninstall such an app from there.

Go to the app store and uninstall the updates. Then open the app without updating. Fixed mine.


How to block ads on Chrome for Android? I am using Adaway & ads are blocked across different apps on my phone. However, Ads on Chrome Mobile are not getting blocked. Can someone help?

AdAway (root) SHOULD block all ad-hosts. So in my case, chrome blocks all ads on webpages because it can not load them cause of blocking the ad-host system wide.

Try updating the host lists in AdAway.

just turn off reduce data in settings and you should see no ads!


/data partition corrupted? I have a Galaxy Mini GT-S5570 running CM 10.1 which was installed about a month back. Yesterday my phone suddenly crashed and after rebooting it got stuck in a boot loop. I tried wiping the cache and data but when the CM recovery starts formatting /data partition it gets stuck. I also did a clean install of GingerBread stock ROM but the problem still persists. Formatting /data partition cannot be done after installing stock ROM also. Did I brick my phone? Can someone give me links where I can download new kernels and fix the problem?

its a kernel corruption. Just install a new kernel.


Do I need to factory reset to root galaxy note 4 SM-N910V? I have the Samsung Galaxy note 4 for Verizon. I believe it is the developer edition because the model # is SM-N910V. I am trying to either install CFs auto root or install TWRP recovery and root from there. So far both fail in Odin. here's the log for Odin for CF auto root,

I did a samsung update the other day and went from NI1 to NJ5, i guess that is the update version. Does updating remove the unlocked bootloader? Do I need to factory reset to be able to install CF auto root and TWRP?

Samsung devices usually have no locked bootloader so you won't remove that. Official updates do however remove any trace of a working root.Your device is nowhere near a developer device but more a custom device served with a custom firmware of Verizon noticeable on the V in your model no.

Because of that custom Verizon model it is possible that the bootlader may be locked as you can see in the log where it says <ID:0/003> FAIL! (Auth).
This means you are not authenticated to flash anything on your device which leads me to the assumption that your bootloader is Verizon-specific and therefore locked.

i got same problem on Galaxy s7 edge, and now this is solved :
Developer Option - on - OEM unlock - On => run odin again. Done.


How to change alarm sound to an MP3 I've tried creating an "alarms" folder on the root of my SD card on my Galaxy Note 3 (Jelly Bean 4.3) then unmounting and mounting it again. Didn't work. Tried an application (Tone Picker) to let me put the song as an alarm but still the song doesn't show up. When I select the song from Clock JB+, I can easily select the song with the File Manager app but the song won't be found when the alarm sounds then it will just sound the regular "beep" alarm

Get Alarm Clock Xtreme Free. There is also a paid version which removes the ads.


How to shutdown or reboot HP Pro Slate 12 tablet without power button? Is there any way to shutdown or reboot HP Pro Slate 12 tablet without using the power button?

I'm afraid the button will wear out quickly, so I'm looking for a workaround solution.

Yes, I know that for rooted devices there are a lot of shutdown and reboot apps, but it is impossible to root this device. It has Android 5.1.1.

Provided that HP has not messed up with AOSP much in your device, you can use Tasker with AutoInput (both are paid apps with 7 day free trial) to reboot/shutdown without using power button and without requiring root access.
In essence, what we're going to do is show the power dialog (the one you see when you long-press the Power button).
(Solution tested on AICP ROM (Android 5.1.1))
Instructions

Install both the apps and enable accessibility service for both from Settings → Accessibility
In Tasker, create a task with the action: Plugin → AutoInput → Global Action →  Configuration → Action → Power Dialog
Go to Home screen → find the option to add Widgets → select Task Shortcut → choose the newly created task → select an icon

An icon would now be placed on your home screen with name as the task name and icon that you selected for the task. Tap it and the power dialog would show up.

In case you want to have a functionality of launching that dialog from anywhere in the system, you can consider LMT Launcher.

Like @Tamoghna said , only way to reboot and shutdown for non rooted device is using adb. You can download adb from this link and unzip it.

Open cmd from same folder and type

 adb reboot

to reboot the device
and type

 adb shell reboot -p

to shutdown the device. I hope it helps you..
