What does „Stranger face“ do?

The switch „Panic on a stranger face“ locks Semanty in the background. It opens only with your face or finger.

Step by step

  1. Open the menu.
  2. Tap „Phone protection“.
  3. First turn on „App lock“.
  4. Set a face or a finger in the phone settings.
  5. Allow the camera if the phone asks.
  6. Turn on „Panic on a stranger face“.

Good to know

  • It locks at once, as soon as Semanty goes to the background.
  • It does not wait 20 seconds like „Lock in the background“.
  • The phone PIN does not work here.
  • The screen says to unlock with your face or finger.
  • The camera also locks when there are two faces.
  • It also locks if someone takes the phone.
  • That is after a frame in which there was no face.
  • It does not delete the keys.
  • If the lock is off, turn it on first.
  • Then it says „Turn on the lock first“.

If it does not work

  • Without the camera it says „No camera permission“.
  • Give permission and turn the switch on again.
  • Without a face or a finger, a PIN alone is not enough.
  • The text says to set a face or a finger.
  • Set them in the phone settings.
