Uninstall system app

This may not work on all devices as some will just “disable” those apps, not showing them as an icon but still listing them among the installed apps, occupying disk space. But at least the process won’t start and won’t occupy memory and use battery time.

  • Connect to the device using adb
  • Check for the name of the package to uninstall with pm list packages -f $packagename
  • Uninstall it with pm uninstall -k -user 0 $packagename, where $packagename is the output of the previous command
