How to disable Android app if no option for that ?
 

As titled, I found my tablet suddenly becomes sluggish, I believe it was some apps I installed to caused that, without uninstall the apps to try I want to disable them to see if any difference, but there's no such option on the settings, and it was not a system app but installed from Playstore, so there must be a way to disable it but how ?

it depends on the version of android and the app. Probably you can remove the permissions, probably you can send it to deep sleep, probably you can hibernate it. You may have more possibilities on a rooted phone but without details hard to say anything. Would be also nice to check resources (if you have enough ram/storage/whatever).

I am running on Android 12, and just learned that there's no disable option at all in the apps settings, it must be hiding in somewhere...
