- Prevents application removal
  Application may abuse the framework's APIs to prevent removal.
  evasion
- Queries a list of all the installed applications on the device (Might be used in an attempt to overlay legitimate apps)
  banker discovery
- Removes its main activity from the application launcher
  stealth trojan evasion
- Requests accessing notifications (often used to intercept notifications before users become aware).
