Removing factory applications
I do not like all Samsung and Google Applications which comes by default with the phone. It collects too many data, runs in background consuming CPU, memory and thus battery power consumes storage space.
- Disable 'Play Store' automatic updater
- Disable all applications which are not needed. Restoring their stock versions if needed.
- Use a Application called Applications Info located in F-Droid package manager to find locations of applications to be deleted.
- Delete using CLI: $ adb shell $ su $ mount -o rw,remount /system $ rm -R /system/app/application-to-be-removed $ rm -R /system/priv-app/application-to-be-removed
file:/system is read-only be default. use
mount -o rw,remount /system to make it writable.
