Access through recovery mode on devices with traditional partitions. Note that many newer devices use A/B partitions where system cache clearing is handled automatically.

Background Process Management

Stop Background Processes

List all running processes:

adb shell ps

Check memory usage by process:

adb shell top -s 6

Check CPU usage by process:

adb shell top -s 9

Kill specific process by PID:

adb shell kill <PID>

Prevent Apps from Running in Background

Stop specific app from running in background:

adb shell cmd appops set <package-name> RUN_IN_BACKGROUND ignore

Force stop an app:

adb shell am force-stop <package-name>

Example – Stop Facebook from running in background:

adb shell cmd appops set com.facebook.katana RUN_IN_BACKGROUND ignore

Bloatware Removal and App Management

List Installed Packages

List all packages:

adb shell pm list packages

List third-party packages only:

adb shell pm list packages -3

List system packages only:

adb shell pm list packages -s

Search for specific app:

adb shell pm list packages | grep <search-term>

Uninstall/Disable System Apps

Uninstall system app (user-level, can be restored):

adb shell pm uninstall --user 0 <package-name>

Disable system app:

adb shell pm disable-user --user 0 <package-name>
