Has worked well for ages up until 7 days ago: No new apps and i rarely use them.
Now several times a day one of two things happen:
1. The screen goes black and the device becomes unresponsive
2. The screen glows plain white and the device becomes unresponsive.
the only way to get it working again is to plug it into the mains and it then automatically reboots.
the battery charge sign is full.
Grateful for a solution
Simon
