Face Scanner Screen Lock Prank is a free Android app developed by ShahApps21 in the Utilities & Tools category. It is a prank lock screen app that creates the sensation of a real face detector app. The app features amazing animations, sounds, and themes that make it more realistic.

One of the interesting features of this app is the moving counter lock screen. Users can set a specific time and when the counters complete and match the numbers, the mobile phone lock opens with the camera. However, it is important to note that this is not a real face scanner and does not take any original face calculations. It is mainly intended for creating tricky jokes with friends and family.
