Facey its a wonderful app shows you who touched your phone without your permission.

How to use :

1 - Activate device admin app
2 - Enable permissions (Camera)
3 - Configure the app

When someone tries to open your device :

- Turn on/off alarm
- Turn on/off flashlight
- Turn on/off vibration
- Lock the screen after 3 attempts

The app automatically takes a picture after the second wrong attempt

Why need you to activate device admin ?

WTMP needs administrator rights to find failed unlock attempts. Android will only detect a password or pattern as incorrect if it contains at least 4 digits / characters or pattern dots.

Enjoy using the app ;)
