Hi, My phone recently decided to randomly turn itself off, And has since not allowed itself to turn back on. When holding the power button the handset vibrates, but nothing else happen's. Also when connecting it to PC Companion, It detects the phone then drops the connection over and over... Please help, I'd like to be able to keep this handset. The Phone is a Xperia Play, Black with a 16GB memory card, And has been regularly updated though PC companion.
