This looks to me more like a hardware issue. Please login or join the forums and post back if the phone was recently dropped or had some kind of moisture encounter.

Please avoid creating multiple threads.

I certainly will (and others will chime in too) but you need to provide more details. Was there a particular event that caused this to happen? Example, phone was dropped or got got wet due to rain?
