Understand why some capabilities are controlled by special settings rather than normal runtime permission prompts.

Core ideas

Use these points to build an accurate technical model before changing the device.

  • Device administration, VPN, notification access and install permissions can change system-wide behavior.
  • Accessibility can read screen content and perform actions on behalf of the user.
  • “Display over other apps” can create deceptive interfaces if abused.

Decision rule

Review special access separately from the normal app-permission screen.

Apply it on your phone

Record the device facts, source and expected result. Make one reversible change, observe the outcome, and keep the evidence needed to undo it.
