Thanks for a great work. I have one but annoying problem. When I talk and bring the phone to my ear, the proximity sensor turns off the screen , but when I take the phone away from my head, the proximity sensor does not turn the phone screen back, and I have to unlock the phone manualy. I am not able to quickly mute, turn on speaker, dial, end call, etc during call. I wonder if this is just my problem and I have to reinstall the software, or is it a bug to reparil, or i missed some option.
