Motorola V551 / V330 / V547 / V555 / V557
Black Screen
I've had my phone for about 2 days and after about 5-6 minutes the phone's screen goes black. I've turned off all the settings that could be causing this but it didn't help, the screen still goes black. This is annoying because if I am in a conversation for more than 5 minutes then the screen turns black and disrupts the call...anyone got any advice???
