What is the best way to remove Android application? - General Questions and Answers

Hello, I am aware that there are lots of third party uninstallers for Windows which delete program leftovers after they get uninstalled and I wanted to ask whether there exists something similar for Android. Even after uninstalling an application I get an error sometimes, mostly when l am trying to install an application. I get the report that the old one is not deleted. I went to the root section of some of the applications as well as deleted data. Seems nothing helps. I hope there is an application which can delete the leftovers automatically (something similar to SD Maid's corpse scanner, just the working method).
Thank you in advance!

Android uses solid state memory, defrag is useless on Android, android doesn't store data the same way PC does, the data doesn't get "scattered" across the "drive space" like it does on PC.

It seems to me like your issue is caused by the fact that you have uninstalled some system apps and now you're getting errors associated with those apps.
If this is what your issue is, the solution is simple.
Anytime you add/remove/install/uninstall system apps, immediately after you're done installing/uninstalling/modifying system files/apps, remember to boot into recovery and wipe the cache partition.
Adding/removing/modifying system files/apps confuses the system because it is looking for data that isn't where it is supposed to be or it's finding data that is there but doesn't know what to do with it because the app it is associated to is no longer there to use the data.
Wiping the cache partition then rebooting allows the system to reload everything correctly into cache so that everything works with the changes that you made.

[Resolved] [Q] Problems restoring apps with titanium backup

This is now solved, to anyone else with the same problem the following were most likely to have fixed it:

I recall there is one thread talking about the similar issue but I didn’t bookmark it.
But you can refer to this first. Check second paragraph from the bottom.
Both threads mentioned about conflict between Store restore and Titanium Backup restore.
The other thread suggests uncheck “Auto Restore” in Setting->”Backup and Restore”. I tried this once before, work for me.
Hope this helpful for you.

I've never had problems restoring data between roms, but I've read many warnings against restoring apps when changing roms.
Also, when changing between very similar roms, you often don't need to wipe data, unless you are "downgrading" to a version compiled from older source.
You can always do a /system partition format and flash a new rom, then see if it will boot without issues. I've also be able to selectively wipe data for problematic apps to fix them.
I really don't like the nuclear option of factory resets, just because it can take hours to bring a phone back to a state similar to the state it was in, and it can affect saved states for some apps that attached to the device ID.

Original problem
I have been having problems restoring apps with titanium backup and so far no one has been able to find the solution, I couldn't find a solution on google and titanium backup support isn't responding to my support request. Anyways, I'm trying to restore apps from pandasa123's unofficial cyanogenmod to matrixzone's unofficial cyanogenmod. When I restore on the free version it opens install window and then when it says installing it changes to app not installed. Suspected problem apps are Bloons TD 5, Drunken Wrestlers and Star Wars: Commander. When I had the free version, it seems after trying to restore drunkin wrestlers and it says app not installed then all the apps after say app not installed except a few like google authenticator. I tried again with the paid version and it still got stuck restoring things like drunkin wrestlers, bloons td 5, star wars commander. I have already tried the troubleshooting steps in tibu and have tried multiple times to restore. I have also tried older versions no luck. I could successfully restore those apps when I went from 4.4.4 to 5.0.
Also would there be any work around to manually restore the apps? Any other backup apps that are good?
Device: Samsung Galaxy S3 SGH-I747M
Rooted: Yes
Anyone?
Please, anyone? I don't want to be stuck with this rom.
I recall there is one thread talking about the similar issue but I didn’t bookmark it.

And one final tip that i use.........when setting up a ROM from scratch, do not sign in to the Google account until AFTER you have RESTORED all the user Apps with Titanium as the Market will try to restore all your apps from your Market user history, which is OK but will conflict with your BATCH RESTORE using TItanium Backup.

Thanks, I don't restore any of my apps from the play store (unchecked "All Apps" in the restore screens on initial setup of the rom) but do have some games connected to Google Play Games. Would this solution still possibly work?
It still doesn't restore properly and it seems to also get stuck on a new game I downloaded called LogoMania too. I didn't add a Google account at setup until I had to go to the play store to download tibu and tibu pro but made sure auto restore was off in settings. I also unchecked the malware detection in google settings and saved the apps to my internal instead of external sd but still no luck.
You're more likely to have problems restoring entire apps with Titanium Backup than just restoring data; if you are having problems, try reinstalling the app from whichever source it came from, then restore data.

So in order to only restore data, I would:
1. Install the app from Google Play
2. In tibu, do a batch restore and select "data only" instead of "apps+data"
Is that correct?

Yes.
One important step before you restore is the verify the backups. Go into TB->batch->Verify Backups. See if everything is okay with no errors.
Also, remember some apps may not be compatible with your upgraded Android version.

I verify every time. Also, I'm on android 5.0.2 already trying to get to another 5.0.2 rom I believe.
One more thing I forgot to mention: if you want to recover an app, try to recover it without data. Recovering data for apps between CM versions, or even app versions, can cause headaches sometimes (especially Google apps).
Also, TB has a website with help. Maybe there is an answer in the docs to help you.
Thanks guys, it worked!

Link2SD completely messed up my phone

Alright guys I'm about to blow my top off here. The most recent Link2SD update completely messed up my entire phone.
For reference, I'm currently running an LG G3 D851 4.4.2, stock ROM and rooted. Everything was fine until recently when I started noticing a Play Store update app error "-110".
Not knowing what it was, I investigated, and found that my entire group of app installations have been completely screwed up.
1) First off, I can't install ANYTHING. No app, no nothing. I need to probably install an updated Link2SD to fix this nonsense...right? Can anyone direct me to how I would install the apk using ADB?
2) My mount script is broken and it's not working. It tells me "Mount script cannot be created. mount: Unknown error 150". As a result, my SD 2nd partition remains unmounted....which I think is the source of this entire problem.
3) Viewing my internal storage through DiskUsage, I've discovered that every single app I used to have installed has been "merged" into a single folder simply called "System data". Referenced through this photo here: http://i.imgur.com/ksukQGG.png . Instead of showing the individual folders, e.g.: Google Translate, Pocketcasts, etc, it just shows that big anonymous block of "System Data".
4) If I go to Settings -> Apps. Every single app shows up with "0.00b" as their app size.
HELPPPPP PLEASEEEE I will seriously monetarily tip someone if they can provide me with a solution to this.

Thank you so much for the detailed response. Unfortunately though, it looks like I already have the most recent version installed, 4.0.9? Would this solve anything by basically reinstalling it? I was hoping there would be like a 4.1 version that would fix the issue or revert changes or something.
Update:
Tried installing an app through ADB and it now shows me this:
WARNING: linker: app_process has text relocations. This is wasting memory and is a security risk. Please fix.
pkg: link2sd-4-0-8-multi-android.apk
Failure [INSTALL_FAILED_INTERNAL_ERROR]
Any idea anybody? Like before, I'd be willing to donate to anybody who can provide me with the solution. Thanks!

Oh, I was trying to downgrade Link2SD in hopes that it would fix whatever happened with 4.0.9.
According to the about page in Link2SD, I currently have 4.0.9.
And haha thanks for the heads up...I'm really desperate though which is why I pulled that card out.

I can uninstall apps, but I can't install or update anything. That's why I was trying to install through adb instead, which unfortunately still doesn't work. When I open up Link2SD, it doesn't give me an option to reload, it only gives me the option to "Recreate mount scripts". If I click on it, it gives me the mount script error - "Mount script cannot be created. mount: Unknown error 150."

Is there any really important data on your installed apps? If I was you I would simply reflash the firmware and start from scratch instead of spending hours to find a solution. The point is that you don't know what you changed that your phone became like this. I have send a email to the Link2SD developer but I'm not sure if he can provide a solution.

I'm actually backing up all my app data as I'm typing this. The only concern I have though, is that my phone is actually on the stock recovery. I only rooted it because I didn't want to deal with the potential for something like this to happen (which would suck up all my time, haha). As a result, I can't flash anything. So if I decide to stock factory reset, would that clean the /system /data, and everything else that needs to be cleaned for my phone to work properly again? I thought that root (and potentially whatever screwed my phone) persisted through a stock factory reset, which would make trying to do that pointless.

I really don't know, if your root survives a factory reset. Probably it will. A custom recovery is really usefull as you can make complete nandroid backups

Well, I solved the mount problem by formatting my SD card. But that didn't fix anything else unfortunately.
I also noticed a couple interesting things:
1) Android and Link2SD show my data and cache for ALL apps to be 0.00b. I know that's not true because I went to the /data/data/app directories and found the data exists.
2) I can use all my apps normally with no problem. that means all the files are there, and can communicate correctly(?)
3) I still can't install any app at all.
Next course of action: Completely disable link2sd's boot script perhaps? So what would that entail, deleting install-recovery.sh from /system/etc/ ? Anything else, or would that be good enough?

Apps randomly deleted (both system and user apps!)

On my (rooted) S7 I suddenly notices that the Google services and play store were GONE. After installing these from GAPPS, I notice that several apps are disappearing.
I don't know why, don't know how, but I do know it concerns both system apps as well as user apps.
eg: I lost Waze (user app) this morning and, after a reboot, es explorer (user app), Google pictures (system app) and the gallery (also system app).
What can I do to prevent this from happening again?
I did make a titanium backup and a TWRP backup, but of cause it's unacceptable to work with my phone: clicking on an icon has about 2% change that the app is gone!
I noticed others that have this problem too, but I have nothing installed to the external SD card (which, btw. is a pain in the @SS with marshmallow)
No one can help me?
Still on every reboot I lose apps, both user and system apps.
Annoyingly is also that titanium backup cannot restore system apps!
I had link 2nd and foldermount, but removed both before. They are not installed, but still this is happening.
Please, please help!
BTW: a factory reset won't get me my system apps back, right?
I'm also having the exact same problem. Tried to search for a solution but to no avail... This is so frustrating...
what apps are missing ?
i have not seen anything like that
Randomly any apps it feels like removing. System apps, user installed apps. Once my google play store got uninstalled.

u say u installed GAPPS , maybe thats the problem
Bright.light did, I didn't.

I think this might be because I flashed ExtSD_Fix_rw-signed-v1.9b.zip
This is used to change the permissions for the external card.
It messes with /system/etc/permissions/platform.xml and /data/system/packages.xml
maybe that got wrong, so I made a factory reset and started all over. Now it works, even with xposed and root.
btw: It's only after I lost the play store/google services that I installed GAPPS, so GAPPS is not the problem.
Same here. I tried to revert to the packages.xml before the flash but it didn't work. Apps still getting uninstalled. So a factory reset did the trick for you? Did u flash ExtSD again after the reset?

No, I removed this ExtSD immediately, just to be sure that I won't flash it again.
For the moment I learn to live with this problem. It's possible because most sophisticated apps are already requesting the correct rights. Including the root capabilities it works as I like it to work.
When there is a better solution, I will TWRP backup and try that one, but this ExtSD is not the correct way.
I haven't found the thread, or else I would have put a warning in there too...
I have changed the permissions and ownership of the files in newer versions. Tonight I will release v2.8 with additional logging to help me finish this thing.
The ExtSD Fix thread is here.

Thank rufus! Still appreciate your work on this. Don't take it the wrong way that I'm blaming this app. Users install at their own risk, so it's all in the user. [emoji4]

No bad feelings ?
My stuff does not work as well as I want it to yet and that frustrates me quite a bit...
Please join the testing team to help. If you don't want to mess your system, nandroid backup before flash and then restore. I hope the apps disappear quickly though... I know it is a pain to loose data/settings/texts/call logs...

I didn't loose those things, however, since my backup was 'old', I just started all over, only retrieving some items from backup selectively.
No hard feelings for the ExtSD, I know it's my own risk
I do hope that the development of ExtSD will continue and that there will be a time that we beat this monster problem! :good: Or that Google finally understands that this is NOT wat we want!
btw: I have several apps which I cannot use anymore because of these ridiculous rights.:crying:
I have the same trouble with missing apps on my rooted 5.0 Lollipop phone.
I find that the missing apps usually have two copies of themselves in the data\app directory.
What I describe will apply to all updated system apps and user apps:
For example playstore is a system app but, after it is updated it is stored as data\app\com.android.vending-1 for the first update. Then data\app\com.android.vending-2 for the 2nd update.
Further updates will alternate between these two storage locations.
If something goes wrong and data\app\com.android.vending-1 does not get deleted you will have two copies of Playstore which I think will lead to a randomly disappearing Playstore.
I delete the oldest dated of the two storage locations and reboot phone. If still missing I reinstall the app and make sure there is only one copy in data\app directory, I will delete the oldest again.
I have auto update apps turned off to reduce the problem. I have a TWRP backup so I do not worry about messing up the phone.
Good Luck!

Galaxy S7 SM-G930F (6.0.1) - System Partition Size

Hi All
I am hoping someone can help... I have the Galaxy S7 (SM-G930F / 6.0.1 / UK / EE) and have come up with an issue.
I use Cerberus Apps in case my phone is lost - you are able to install this into the system to avoid someone wiping the phone and removing the software. To do this the phone must be rooted and then I usually use Link2SD to transfer the app to make it a system app. This has always worked on my old phones - but alas not this time.
The problem is that the system partition (4Gb) is full!! I have deleted all the language packs to try and clear some space - but it is still full! Strangely enough I also uninstalled an "Amazon" app which was listed as being a system app and quite large (from memory I think it was just under 100Mb)... but when I removed it and rebooted the system partition free space remained unchanged! It's possible that Amazon was a user app and I mis-read it... but anyway - I thought that the only way to clear some space was to resize the system partition - so I installed TWRP (3.0.2), have done a complete backup (system/efs/etc) apart from \data as this showed 0Mb and "failed to mount" when I tried to back it up originally.
So, my question is - can anyone help me to free some space from the system partition to allow Cerberus App to be stored there? I did think about uninstalling the VR Gear files as I dont have a VR device and assumed I could re-load these from Google Play if needed - but I do have the Galaxy Gear watch - so decided not to remove these files in case it screwed this up. Not sure which Google Apps I can remove and re-install if needed... so if anyone knows this, then that would be a help too
I thought you could resize the partition in TWRP but cant find any clear details on how to do this, so thought I'd ask here before I screw the phone up :silly:
Any ideas/help greatly received.
TWRP doesn't support encryption so that's likely why /data won't mount. Resizing partitions is typically done via Odin with PIT files, but it's very dangerous, so I wouldn't recommend it.
Luxembourg ROMs have around 130mb free system space, so there must be a ton of carrier bloat in yours. This doesn't sound right though, it's required that there is some space for expansion. Could you run the following command in a root terminal and post the results please?

Thanks Curtis - I left my phone at home today, so will try this tonight and post results. After deleting all the unwanted language files I have about 40Mb space free, but this still doesnt seem to be enough as when I run Link2SD and reboot the phone, Cerberus has vanished and has to be re-installed... although when it re-installs it shows it as an "update" which would indicate that it is installed already - just 'lost' ???
Will update tonight when I get a moment.
Thanks
That's interesting actually. It seems to be indicative of permission issues. The app was successfully moved to the system, but the permissions on its files were wrong and the system refuses to load it(Link2SD's fault, essentially) . It's still acknowledged by the app manager though, which is why it can be "updated". Can you try move it with something apart from Link2SD? I recommend titanium backup.

Thanks Curtis - I have Titanium Backup (free version) installed already so can give it a go - I have only used it for backups (a long while ago) and have never used it to relocate an app... is it fairly self explanatory how to do it?
Will look tonight when I get in
Thanks
Just tried with titanium myself and it fails in a similar manner. Seems Marshmallow is a little fiddly and Link2SD puts out a generic message when it has issues. Titanium just freezes. You'll have to do it manually
First you'll need to clear the system of failed attempts. Look in the /system/app and /system/priv-app with a root Explorer for Cerberus apks or folders. Next, look in the /data/app folder and find the Cerberus folder. Take note of this path.
Next, fire up a root terminal and enter the following commands. In my case I was moving Greenify.
mount -o remount,rw /system
cp - a /data/app/com.oasisfeng.greenify-1 /system/app/Greenify
Replace the data folder with your noted path. The system path can be anything.
Then reboot and the app should be system.
Hi Curtis
Thanks for spending so much time on this.
OK, I skipped straight to the manual relocation method that you said. Whilst the app is Cerberus the APK etc is called System Framework as I have installed the 'hidden' version rather than the one which shows as Cerberus on the phone. However using OI File Manager, when I look in /system/app and /system/priv-app folders there is nothing called Cerberus or System Framework... so I am assuming that there are no orphaned APKs or other files.
But, this is where the strange thing starts, when I look in the /data/app folder, it is empty... so I am guessing I am looking in the wrong place as there are loads of apps! I am looking from home then selecting data, etc... any thoughts?
Oh, I have checked that hidden files are shown too!
Thanks again
i used to install the same app on my S7
please follow this guide & let me know the result.
1- uninstall Cerberus App, Link2SD, TTb, etc. and reboot
2- install SystemCleanup.
3- from the app SystemCleanup swip to tab apps and remove some bloatware like Google books, music, games, google TTS.
4- Reboot & install Cerberus App, do not run it.
5- from the app SystemCleanup go to apps tab and move Cerberus App to system/app & reboot again.
6- That's all.

Hi Abuzar
Thanks for the help... I tried using System Cleanup and initially it didn't work... it didn't show System Framework after cleaning up which made me think it was uninstalled properly. But when I tried to re-install it I got a message asking if I wanted to update the the built in application... so I said yes and re-checked in System Cleanup and it was visible, so I tried uninstalling it and after a couple of attempts it succeeded.
Then I re-installed and it installed it as a new app and it was visible in System Cleanup as installed in /data. So, I moved it to /system and configured it. It now lists in System Cleanup as being installed @auto system+data... so I am assuming it has installed properly... but not 100% sure as it lists some of it in data - so not sure if after a reset it will wipe the user profile from Cerberus or not.
I took a backup in TWRP and thought I would do a factory reset and test it... but on the S7 using factory reset in O/S it asks for my samsung password etc so looks like it may delete my Samsung/Google account's so didn't proceed as I didn't want to delete any online info. So... I tried factory wipe in TWRP but it just said failed "could not mount /data and unable to find crypto footer" and a few more "failed to mount /data" errors... so I gave up and will have to assume its installed properly as a system app
Thanks for all your help.
Just as a final note, the system+data combo sounds normal. Under regular conditions, the system partition is read only, so in order to install any updates to system apps, Android actually installs them as data apps, but cross-references them to system apps and gives them the relevant permissions. You can remove the data part by selecting "Uninstall Updates" in the app info page.

Virus on new phone (Protruly v10s)

So I bought one of these babies from an online Chinese website, after using it for a while, I noticed a few random apps here and there would keep installing themselves (emoji flashlight being one in particular) . I decided to scan for viruses and wouldn't you know it, there were quite a few of the trojan variety. anyway, so i decided to do a factory reset and then I installed malwarebytes to do a scan and what do you know, theres a trojan attached to a couple of the built in system apps (contacts and file manager) which unfortunately I cannot delete, only disable.
So the next step I thought was to do a clean install but it seems to be the case the phone must be rooted before this can happen - and being an obscure brand (Protruly v10s) theres nothing in the way of a guide for rooting for this particular model, or indeed even manufacturer.
so i was just wondering if anyone had any thoughts how to best manage the situation going forward, is disabling the infected apps enough or is the case the apps need to be deleted, and if so, what steps can i take to get this to happen.
thanks
Anyone?
China they are watching us.
Apk apps on file manager
Have the same issue here. Even after deleting each apk in the file manager and reset the phone. The apps keeps coming back. You can also see the apps in the file manager by using esfile manager. Select phone memory and search apk. It will show all the apps that is automatically installing in the phone. Try to delete it but it is like an ai monster it keeps respawning. Hope there are experts that can help us in these issues.

The only options I can think of are:
1) find some way to root the device and remove the problem apps completely from system.
2) if the stock firmware is available for the device, you can try downloading the firmware then extracting the firmware to get access to its content, then remove the problem apps from the firmware then repackage the modified firmware and flash it, it should no longer have the problem apps after flashing.
3) if the original firmware isn't available, you can try finding a compatible firmware from a device with the exact same hardware and try that firmware, if that firmware also has apps that are virus/trojan, remove them before you flash the firmware.

Also, if you're uninstalling the apps but they keep coming back after you reset the device, that seems to suggest that there is a hidden partition on your device that contains a copy of the system apps and it keeps restoring them from that partition when you reset the device. I have a Azpen A 750 tablet that does the same thing, I can uninstall the apps and they stay gone until I factory reset the device, then those apps come back.
It's kinda the same as the process on a Windows laptop that has a recovery partition containing a copy of your Windows system then using the "restore to factory defaults" option to reset the PC.
