I first noticed this problem last week - the phone is '3' branded (UK), un-rooted, running the stock firmware.
If I install an app from the Market and then subsequently try to un-install it via any of the usual methods (App settings, drag un-install from the apps screen), the un-install process just sits there showing a progress bar. CPU usage goes up (e.g., 50% on 2 cores) and the phone gets hot. The application, however, does not get removed. If I then try to use ADB to remove the app, the process never returns.
If I reboot the phone and try ADB to un-install again, the app does actually get removed.
Anybody know what's going on here? It's kind of annoying to have to reboot the phone and use ADB whenever I want to remove an app.

Hi everyone,
Just came over from an old HTC Touch Pro on Windows Mobile and am loving the android platform. I have just flashed Cyanogenmod 7 along with Google Apps and find the system quick and stable. However, I would like to remove the following applications:
Wifi Calling (I have a UK Vodafone SIM so this is useless as says SIM invalid)
VoiceDialer (I find the pre-installed algorithm inaccurate)
I have tried to remove the .apk's via adb as follows:
Code:
adb shell rm /system/app/%APPNAME%.apk
But when I do this I get a looping force close error on the phone about kinetic process and this forces me to reflash whole ROM again.
The .apks I am removing are:
MS-HTCVISION-KNT20-02-GB-A0.apk
VoiceDialer.apk
So I guess I must start by asking are these the correct .apks?
If so, then is there a way of removing these two apps safely from the ROM build?
Also, I might keep Wifi Calling if I can get it to work with my Voda SIM is this possible?
Thanks!

I usually use titanium backup (from the android market) to remove unwanted/unnecessary system apps, works fine for me. About the force close loops, just do a reboot of your phone and it should be fine.
I get the force close loop uninstalling wifi too, but if you just reboot it goes away...
have you rebooted (you can either pull the battery or use the reboot prompt if you're quick)?
also, when you uninstall wifi calling, uninstall ganoptimizer apk as well.

What is gan optimizer.apk just out of interest?

ganoptimizer detects when you are on a wifi call and then sets wifi to "high performance" mode. it was a fix implemented to help with stuttering issues in early versions of CM7.
it's not necessary to keep if you uninstall wifi calling, though, because that is its only trigger.
Thanks guys for the heads up.
Removed the packages via adb and pulled battery and force close loop no longer there. Have you had an impact on system stability by removing these .apks? Or are they totally independent and safe to remove? I do not like things on my system if not being used but also am all about a stable phone.
Best,

Hi all,
I have a standard HTC desire on which I lately have problems with the android market app.
Yesterday I could not download any updates from installed apps - I got the "download failed, try again" message.
I tried to empty the cache from the market app, tried to restart the phone and I also found a suggestion to empty the android_secure folder on the sd-card. That didn't work either.
Then someone suggested I'd reset my phone to factory settings, but unfortunately without succes. Since doing that (both before and after restoring my backup'ed apps and data) I get the same message again. I am not able to update any app I have on my phone at this stage - they are displayed in the market app but downloading fails.
(I was at first able to select apps I already had installed on my phone from the market-website via my laptop browser and have them delivered to my phone, but that stopped working also - it weren't the updates anyway.)
Now every time I start the market app it crashes the first time I start it and then after restarting it displays the message "Application not found" for any app I select (either to be updated or new apps).
Anyone who can help me on this one?
Apparently the problem solved itself. I had the feeling the phone performed much slower though and did another reset to factory settings and since that everything works fine again!
Problem solved...
Alright folks, I think I have finally managed to solve the battery drain problem after the 4.3 update, thank God!
The bad news is that it cannot be done without your phone being rooted. So root the phone in the following manner: 1) Install "Kingo Android Root" to you PC. It will not root your phone without following the other steps.
2) Install "System App Remover" (the one by Jumobile) from play store. The app will be installed as a different name, as "Uninstall". I tried "All-in-One Toolbox" too but it coudn't find all the files listed below (namely KLMS Agent). So I had to install this one and try again.
2.1) Install "Root Checker Basic" from play store.
3) Go to Menu>Settings>More>App Manager>All and force stop the apps:
com.sec.enterprise.knox.attestation
com.sec.knox.eventsmanager
Security policy updates
KNOX
KNOX -- (Yes we have two of them! One is to install Knox interface other one is the one that is already running without installing the other one.)
Knox Notification Manager
KNOX Store
KLMS Agent
In total we have 8 files (or actually apps) to close. You may have 7 of them if you don't have Security Principle Update.
Some of these will not gonna allow you to force stop, never mind, just close the ones that you can.
4) (Now you have to be quick because somehow these apps restart themselves.) Connect your phone to your PC and run Kingo and click root then follow the instructions on your pc screen. Your note 2 will restart and will be rooted.
5) Disconnect your phone.
6) Run "Root Checker Basic" and click "verify root access" and see if you are rooted now. (You should be rooted.)
7) Install "SuperSU" from play store.
8) Run "uninstall" (which we obtain by installing "System App Remover" (the one by Jumobile)). SuperSU will ask for root permission for uninstall, approve it. Uninstall will provide you a list, choose all the apps listed above and uninstall them. KLMS Agent will not be in the list and you should use the search option of the app. If for any reason you don't see any other app in the list search and uninstall! YOU SHOULD DELETE ALL 8 FILES!
9) Restart your phone.
After you remove all the Knox bloatware and anything else you don't like, install Lucky Patcher.
This is usually used to remove licenses from pirated apps, But it also does something else which we will need to use:
It removes Google ads! And these are that keep our phones awake.
In the faulty 4.3 Samsung update apps with Google Ads always try to connect and sync thus keeping the phone awake.
In Lucky Patcher go into each app individually and choose "Remove Google ads".
Then choose "Patch to remove Google ads" and press "Apply". Rarely will you have 100% success but it doesn't matter.
Then repeat the process and this time press "Disable Ads Activities" and press each activity that is used for advertising (They are usually in orange colour).
One more useful step is to use Greenify to hibernate almost all processes except the ones that need to sync eg Dropbox.
My phone used to have 65-85 % wake time after the update. Now it's only 3% wakelock instead of the 65-85% that was before and the battery only went down to 98% from 100% in 2.5 hours! Battery life is even better than on 4.1.2.
If for some reason after a few days (or even hours) the problem returns, then it could well be an app that causes it, or a combination of apps. In my case it was Automatic Call Recorder by App.liqato (Appstar Solutions). an app that was working fine on 4.1.2 but not on 4.3. It was the last app to be installed, that's why I knew. I uninstalled it and batery life is back to normal after it had gone mad for a couple of hours. Notice that no wakelock app showed it as the culprit. I only knew because after I had done a factory reset I installed all my apps one by one and not from a backup and I forgot this one. I remembered a few days later and when I installed it the drain started.
So hello there!
I'm having the following issue and I'm kinda out of ideas.
I was running a (KingRoot) rooted fireOS 4.6.6.1 (420) if I'm not mistaken.
So this is what happened:
Phone was running just fine, but I wanted to get rid of the facebook background services which kept running without the actual app installed. Also a friend proposed to run the 'fstrim' command. So reading through xda I found an app called 3C Toolbox (http://www.3c71.com/android/?q=node/916) which seemed to be safe to use. Installed it and still didn't change a thing except for the three 'fstrim' actions to perform. After that I restarted my phone.
Powered off just fine, but at the start only the 'Amazon' logo comes up and vanishes into a black screen with the backlight still on. Even after waiting several hours nothing changes.
So what did I attempt to get it wirking again?
At first I tried to simply restart it. --> Nothing changed.
Tried to get into recovery and clean the cache. --> Nothing changed except the 'Amazon' being on for a bit longer
Get into ADB and try pull/uninstall... --> Guess due to the locked bootloader I'm not allowed to issue any command other than 'adb sideload [packagename]' for system updates. As for ADB itself I can only get it to recognize on the PC when I get into recovery and choose the 'apply update from ADB' option.
Get into fastboot according to this tutorial (https://forum.xda-developers.com/showthread.php?t=1668159) --> doesn't work.
Get into 'Safe Mode' with this tutorial (https://forum.xda-developers.com/fire-phone/help/how-to-fire-phone-to-boot-safe-mode-t2828240) --> doesn't work either.
So does anybody has another idea I could give a try or should I just abondon all my data and flash a new clean image?
Also I'm not sure if updating from ADB will erase all personal data too. Guess so, but maybe I can get a clearification in here too.
My setup is a Oneplus 3 with OOs 5.0.1 with TWRP, Magisk and Franco Kernel. Naptime and Servicely are two other installed apps that interferes with the normal system behaviour.
My phone randomly reboots two to four times a day, whenever that happens sometimes the booting completes (with longer than usual times), other times it stay stuck at the boot animation and I have to manually shut it down and power it on repeating the whole process till I get a successful boot.
Some suggested to look at the logcat but from my understanding using a logcat viewer, the log starts from the boot so I can't tell what happened before the reboot.
Before proceeding with a trial and error approach by removing everything (the kernel, apps and magisk) is there a smarter and more efficient way to tackle down what's happening?
I will try to use a terminal emulator app to run in background 'logcat -f myfile.txt' but since I down know when the next reboot will happen the file might get HUGE.
