[Samsung Galaxy Tab A series Guides, News, & Discus] kennyk09:
After the recent stock ROM update to Android 10, I started having issues opening some apps. Also I couldn't reinstall some apps. Instead of troubleshooting each problem, I decided to factory reset.

Before the update, I was focused on deleting as many apps as possible. That was my goal.

And that led to many system related problems eventually, and the problems became worse after the update. Deleting as many apps actually doesn't help much in saving disk space anyways.

So I decided to change my approach. I now

focus on disabling as many unnecessary services and process from ram and from running services which consume battery. Nothing needs to be deleted, only disable in adb. No root is necessary.

I chose not to disable:

-any apps which may cause potential issues, especially system related ones,

-apps not running frequently enough to to consume battery,

-apps which I can't find enough information about, to be safe.

This is a better approach to maintaining healthy system without having any issues.

I first disabled unnecessary user apps and sytem apps which don't seem to create any issues.

Then checked in device care -> memory and disabled several residing ones, also those in cached ram. I also checked in developers option -> running services and disabled ones I don't use but comes up active frequently.

For unknown apps, I looked them up on Google.

It's still possible my list may include important apps which shouldn't be disabled.

It's also possible more safe apps can be added to the disable list.

Your input is appreciated.

After disabling all in the list, battery lasts much longer and system is operating very stablly.

So far I get only settings crash when I tap disabled functions like digital wellbeings and others, this is an expected behavior.

This approach is surely better for the system than "delete as many as possible" approach.

I didn't even delete Knox and other system apps as this is a conservative approach.

Yet it saves more battery than previous more aggressive approach.

I'm not responsible if anything goes wrong. Do it at your own risk. If you disabled them, you can always enable back if you start having any issues. For command related questions, ask Google.

1. Factory reset

2. Do initial setup

3. Disable apps in below list

4. Some apps need to be force stopped within app info, even after disabling them from adb. I don't know why but it's just one time thing. While in app info, clear all/casched data too.

5. Don't forget to: restrict location usage, other permissions, put apps in deep sleep, turn off notifications, enable power saver

6. Enjoy long lasting battery (

screen on time 10+ hours

) without any system instability
