Questions about system app freezing/uninstalling/OTA on Android 10 - Android Q&A, Help & Troubleshooting

Hello everyone,
it seems like with Android 10 the whole freezing/uninstalling process of system apps has changed. And it can also somehow make you fail to install any OTA updates later on.
I couldn't find any definitve answer to some of my questions (maybe because Android 10 is relatively new). So here I go:
Freezing apps:
1. Going into "settings -> apps -> show all apps -> 3 dots -> show system -> disabling any app" is the same as freezing an app with e.g. "TitaniumBackup Pro" or "App Freezer"?
2. I understand that if I freeze an app, another app (or the system) can't call/start the frozen app in case it is needed?
3. Could this lead to system crashes or higher battery drain because of frequent requests of an app trying to call a frozen app?
4. Freezing an app and applying an OTA update will keep the app frozen?
Uninstalling updates of system apps and getting more storage:
So the system app itself is inside /system/ but only the very basic version of it.
Every update of a system app is stored inside /data/.
So basically, uninstalling every update of all my disabled system apps would give me some free usable storage in /data/
5. Is that correct?
6. Uninstalling updates but then applying an OTA update will only (if ever) update the system app but will not add anything to the /data/ location?
7. Or would I have to uninstall the updates manually again from my frozen apps after an OTA to relief the used space in /data/?
OTA Updates failing to install because of freezing:
Tampering with the /system/ partition will make any OTA updates to fail installing. Often it seems to be enough to just mount /system rw.
8. Does that mean freezing on a rooted device via "settings -> apps -> 3 dots -> disable" will already prevent me from installing any OTA update?
9. Does that mean freezing on a rooted device via TitaniumBackup Pro will already prevent me from installing any OTA update?
10. Does the magisk module "Terminal Debloater" work and how is it different from 8. and 9. ?
A lot of questions, I would be very happy if someone could answer them.
Thanks in advance!

[Q] Solution to insufficient space? Google Play

I am using in my CM9 in my vibrant after a brick and installing a 2.1 rom, I can not downloading more applications after installing some small applications, does anyone have a definitive solution to this problem? Thank you.
I can't tell if you're on cm 9 or 2.1 right now but...
On 2.2 disabling voodoo always worked for me, if you're using it give that a shot.
If you're running CM9 you might be running low on space in your /datadata partition. Tell it not to use it with this command that you can run in terminal emulator:
Code:
su
touch /datadata/.nodatadata
(Had to Google the correct command/what it is myself)
I've been able to get around that by clearing the data for the Market/Google Play Store app.
System Settings -> Applications -> Manage -> All -> (Market/Store app) -> Clear Data.
I played with ics for a few months and never had that issue. The only time I ever have is on 2.2 roms with voodoo. I remember seeing a thread about this a long time ago too, I think it was in the i9000 forums though. Other than that the only time I've had that error before was way back on the g1 when I actually ran out of space lol

This has worked for me on froyo. Google play kept popping up with a space error when trying to download new apps.

[Q] problem with root/ uninstalling apps

Hello. I'm not very experienced with android and recently got a new z ultra (6802). I think it came with 4.4.2 or 4.4.3 i'm not sure, but as soon as i turned it on i was notified to update to 4.4.4. All went well and one of the first apps i installed was clean master. I hadnt tried to root the phone and i was thinking about it mostly in order to get rid of some preinstalled apps, but i found out that clean master had an option to "deactivate" them so they disappeared and all was fine. The last few weeks i loaded the phone with all sorts of useless stuff i wanted to try, and today i tried rooting it using this tool and everything worked ok. Then i did a hard reset and started setting everything up again... But this time clean master, root app delete and 2 other apps of the same type wouldnt uninstall system apps (despite having root access now). Any ideas on what to do? Is it because of the root - should i try to unroot it? Where can i find these ftfs needed? I saw some in the forum but they are for 6833..

Well, clean master is one of the app I hate most. Killing app processes frequently and clearing app caches are the bad ideas for android devices because android system always try to restart apps everytime you kill. So it greatly reduces battery life. Clearing caches can make apps to start slowly.
That's not the point, right? But just a suggestion not to use task killers and cache cleaner if you have enough RAM and storage space.
Ok now for your problem not uninstalling system apps,
-Install ES File Explorer
-Tap the upper left of the app (three striped shape)
-Tap Tools, Tap Root Explorer (not on the button "On") giving/allowing/authorize root access
-Now Tap Mount R/W and choose every partition as R/W then Tap OK
-Let's get back to explorer, Tap the upper left box labelled as "/" (it will redirect you to root of the Device)
-Go to "system" folder in explorer
-There are two folders in Kitkat, namely "app" and "priv-app"
You can now choose apps to be uninstalled that you couldn't uninstall inside these folders by removing any apps (and .odex files) by Long pressing on apps and choose multi apps at once.
For me, I don't delete apps that I wanted to uninstall but I cut them and create a new folder on sd card and paste them all in that new folder for later needs (you can navigate to internal or external storage from the upper right box of the Explorer, to create new folder, tap on the button with "+" sign at the bottom left corner of the app). Don't delete apps that you don't know well because doing so can prevent your device from booting up.
P.S. You can also install apps as system ones in that reverse way (copy, paste from external to system/app). Remember not to include space in the name of the app you wanted to install as system.
Remember to restart the devices after moving/deleting apps.
I think you now understand how to do. Good Luck, mate.
Thanks for taking the time to help! and es file explorer looks like a really nice app. i followed your instructions and moved some of the apk and matching odex to sd card. the problem is the apps didnt dissapear from the list and as soon as i was done play store was downloading new versions of the apps i moved... what i dont understand is why it worked in the first place when it was new! could it be the sony firmware it came with? since this failed, is there an app to freeze these things?

One thing I left to say that you must restart your device as soon as you finish moving/deleting system apps. After rebooting, the device system will delete app leftovers. It will solve your problem of not disappearing from the list.

No system apps to hibernate with Donation Package ?

Hi guys !
I have been using Greenify for quite some time now and finally decided to get the Donation Package in order to unlock some more advanced features.
There's no way to know (or so I think), but I guess deep hibernation, at least, works fine. However, even though "Greenify system apps" is ticked, the only change I noticed in the wizard is SuperSU, which appears when ticking the box in the right up corner menu. I did reboot several times, but with no luck.
As for my configuration, my device is a Honor 5C L51 on Android Marshmallow. I use the EMUI stock ROM (v4.1.2 at the moment) and Nova Launcher Prime.
Do one of you guys have any idea how I can greenify my system apps ? Or is it normal that only SuperSU appears on that list ? I do understand that these options are experimental, but if there is something I misunderstood to get this working, please let me know.
Thank you for your time.

- is device rooted?; can't hibernate most system apps w/o root
- make sure working mode is set to 'root' in settings
- if still no joy consider making Greenify a 'system' app which gives Greenify some additional powers if not running Xposed
- that said there are few (often no) system apps that benefit from hibernation

Thank you for your answer.
I am root and Greenify's working mode is "Root + Boost (Xposed). I'm confused about what you're saying though, how can one change an app priviledge from user to system ?

If you have Xposed there is no benefit to migrating the Greenify apk to the system partition. Make sure Greenify actually has root permissions. Change the working mode to 'non-root' and then removed the related entry from SuperSU (or whatever root manager you are using). Return to Greenify and select boost mode [or whatever is need to return to "Root + Boost (Xposed)"]. You should get a SuperSU prompt ... either immediately or when attempting to manually hibernate an app.

Just did all that and nothing changed. I also tried to untick the "Greenify system apps" option box and tick it again with no luck. However, I noticed that I could actually make SuperSU appear and disappear from the list of greenifying apps like I mentioned in my first post even if the box is unticked.

Not much more to say. Either: 1) you have no system apps running aside from SuperSU [seems unlikely]; or 2) Greenify does not have sufficient permissions to see and act upon system apps. Good luck chasing this one down.
SuperSU typically runs as a user app regardless of how Greenify characterizes it. You can check current status from within SuperSU.

Notifications only coming when opening app!

Hey guys,
I'm on latest MIUI 11.0.8.0 Global Stable, bootloader unlocked, rooted, and with TWRP. I debloated using XiaomiADBFastbootTools, but then went a little overboard and removed all "the crap" using SD Maid Pro's App Control. I made sure I searched on google before removing anything. I've even removed the Battery Saver app.
But now after doing this, the problem is my notifications are not coming. It's as if the phone kills all apps in the background. Like I'll open WhatsApp and all the messages will load at once. Same with Hangouts, Gmail, etc.
I downloaded the current rom again by going into Settings > About Phone > System Update > Download latest package. It downloaded the 2gb rom and booted into TWRP and flashed. I again rooted, installed Magisk, etc, but this is not fixing it.
What should I do? I even cleared Cache/Dalvik Cache and that didn't fix it.
Please help
Change battery optimization settings
Hello,
Open your app settings and set battery restrictions settings to no restrictions.
For example, you wanna do it with whatsapp:
1. Tap and hold whatsapp icon.
2. Select app info.
3. Select battery optimization/restrictions.
4. Change to No restrictions from MIUI battery saver.
5. Move one step back again and turn on Auto start option.
I hope this will solve your issue.
this happens when I restore with migrate, it is something related to interaction between apps and google play services as i recall.
for the apps like WhatsApp, gmail.... and g pl services, try to clear storage of the apps then sign in again, then go to twrp and clear caches, hope these steps solve your problem
I tried all of the above, and I'm still facing issues. Something interesting happened. I have the Outlook app installed, and there is an option of "Test push notifications" in Troubleshooting. I tried it and it gave me the message "Timed out waiting for a notification. Make sure you have enabled notifications for Outlook in the Android settings."
Another issue happened with the Warframe Android app, where it was not able to enable push notifications.
Now I am 100% certain I have removed/deleted an essential process using the SD Maid Appcontrol (mentioned above).
How do I reinstall the complete ROM and reset all the settings without losing data?

I don't remember what processes I deleted. They all seemed "crap".
Is there any way I can reinstall the entire ROM, reset all the inner settings, but still keep data?
If not, I guess I'll start taking backup coz I just lost a job because I didn't read the email on time -_-

Thanx. Installing Migrate.
BTW, another weird thing. I don't get notifications that there are updates available for my apps in play store. I manually opened my Play Store, clicked My Apps, and it showed 15 of my apps had updates available. I'm really getting pissed off now -_-
I fixed it I took backup of the important apps with Migrate and then wiped everything, even the internal, and then using TWRP, I installed the latest Global Stable (V11.0.9.0.QEJMIXM) recovery rom and then rooted and installed Magisk and restored the backup with Migrate. I even debloated again but this time using XiaomiADBFastbootTools 7.0.
This fixed all the problems I was facing, and everything is working perfectly fine.
Thank you so much guys, for all the help. Really appreciate it

Accidentally went too far adb uninstalling system apps, system now half broken, how to fix?

A few days ago I had a joyful night uninstalling a bunch of system apps with adb pm uninstall. Maybe because I did not check thoroughly on which package I should uninstall, now I have faced some consequences: OneUI Home crashing on widget page, settings crash on accessibility page etc..
So I am fixing the phone right now. Since I deleted system apps, so factory reset may not work (?). I think I can also flash a factory rom on the phone if needed. However, it would be great if I do not have to wipe everything since some of my apps' data cannot be backed up easily.
I am thinking about grabbing a factory firmware, extract all original apk and try adb install them back, that will make the app a user app, so will that work? Also for future references, is there a safer way to backup an apk file before I attempt to adb uninstall?
Edit: S21 home screen pinch to widget screen crash: Apparently I am not the only one. There might be a bug at One UI Home's late February update.
Factory reset.
A package disabler can be an easier/better option plus you can do it on the fly as needed.

The only NON-root solution that let’s you disable any unwanted packages that come pre-installed / installed with your phone / tablet.

I've been using this one for years.
I know it works with Pie. Lol, no Q for me.
Updates can kill it so if it works... leave it be.

I was thinking about making a script to do that. (And my baby step almost killed my phone).
Forgot to mention I actually did not know the existence of package disabler you linked. I should give it a try.

It's a good app. Useful in tracking down issues as well since it's running in real time.
It can also clear system apk caches that Settings can't touch presumably because the latter leaves nulls. I was able the repair a system apk cache glitch like this saving me a factory reset.
Just protect your critical data; OS's are expendable
ADB AppControl appears to be safe as it backs up .apk if user selects Uninstall
