Within two months of normal use of Motorola Defy, it has started showing up with issues. I have recently noticed that a part of my mobile screen is not responding and seems to be a complete dead patch. When I use the keyboard, sometimes few letters are not responding to the tap of my finger. I am unable to understand what must be causing this problem. Does anyone know what could be the issue with my mobile phone? Does anyone have a solution or this? If yes then please reply my post and help me get rid of my problem.
