How it works?

Note

All checks are performed on a background thread (Dispatchers.IO) to ensure your device remains responsive during the scan.

  • If "Search Root" is pressed, it Checks 40+ System Paths to Find Traces of Root Access. If it finds, Root Traces are Found. If not it is clearly shown.
  • Now if "Verify Root" is pressed the App Executes su -c id and if it returns 0, Root Access is Verified. Else, Root Access not Available.
  • For BusyBox Checker, it checks BusyBox Specefix Paths. If not Found, the App executes su -c which busybox to verify BusyBox Installation.
