Something bizarre happened to me just 1 hour ago. I just came back home from my home town using Nokia Drive (aprox 90min) and everything was completely normal. After i parked my car and got the mobile, it shows a green vertical line on the screen. It´s visible in every app and not in the main menu. Tried to solve it by powering off and on again, restoring...so i assume that´s a screen problem. Have you had that problem?
I wouldn´t like to send it back to the nokia care point, as it has all my job documents, contacts....
Thx!
