My 8100 keeps shutting after a few minutes, before it shuts of the camera flash comes on really bright and then it goes off, the phone led then flashes red twice as if it is about to reset and reboot, sometimes it does, however if doesnt stay on. when it goes out the led goes it to sequence of three quick flashes, the it pauses, then two quick flashes then pause then back to three flashes....what do I do? I've tried wiping and reinstalling without restoring backups same issue. Any suggestions
