My Galaxy S2 mini keeps showing the Lock logo, while only a few seconds into a call. It disappears after tapping it twice, but reappears again! So annoying. Somebody help me!
Hello mate!
Is it a lag? I will advice you to shut down the LOCK screen from your settings. The moment you pres the power button the phone is LOCK and if you press it again the phone is UNLOCK. You will no longer use slides or somethings to unlock your phone and the problem should dissapear
Good luck!
