I was playing around with some settings on my N95 8GB and turned an option called 'Screen Rotating' to the automatic setting. I also turned my screen brightness to maximum. This now casues my phone to keep rebooting. My phone will power up and then once the front screen has loaded the moment I go to do anything it then reboots again. How can I change it back or manually reset it? I can't update the software as the phone does not stay on for that long.
