Then works brilliantly for 2+ days. It can be more than a week. Could it be an app or hardware problem.

I would recommend that you first try shutting it down completely by holding on/off and vol+ at the same time for 10 seconds.</P> <P>If that doesn't help i recommend that you try making a repair of the software using a computer and the USB-cable.
