With this setting on, any press of the power button during a call ends it. That includes pressing it to wake the screen, for example to reach the dial pad in a phone menu. If you often need the keypad during calls, leave it off and hang up with the end call button on the screen.

During a call the screen turns off when you hold Kompakt to your ear and should wake again when you move it away.
