I've had the feeling my N8 has been on it's way to dying for a while...and then this happens..........
I have just picked it up and it's vibrating like somebody is phoning me, but the screen will not respond, and Yes I have tried hard resetting it, all that does is make the screen flash on and off a few times. The screen just goes back to being unresponsive...it's driving me mad.....heeeeelp
Thank you in advance
Sounds like you would need to get software re-installed at Nokia Care facility at the very least now.
