I'm not quite sure anyone else is having this problem - I searched this thread and found nothing... When I answer a call, sometimes the call screen gets minimized and switch orientation to landscape mode. When my call is ended, I have to maximize the call window again and then wait another second or two in order it will switch back to portrait mode so I could press the "END" button...
Is there anything you can do about it jaeezzy? Maybe something is "stealing" the focus from the call screen, and forcing it to minimize?
