i have a gn2. and when making a call the screen blinks in and out . i cant hit any of the buttons to control anything. can somebody tell me what this . and how to fix it ??
as your Note 2 should be still under warranty, you can simply ask the service centre guys to do a check. Very likely, it is hardware issue. If you do not want to visit service centre, you can try to do a factory reset. Of course, you need backup your data before resetting.
