I LOVE the phone.. my phone just likes to restart it self at random times..I would still buy /get a new one.
Try to disable wi-fi (WLAN) - well, it was a problem with Lumia 920 a year ago, but then there was an update and that problem was gone ....
Of course, if that continue, try to get a new one ....
Jarip!! THANK YOU!!! this seeems to be the problem.. No random restart today (never happend before) when i have Wlan off
Everyone who mentioned sensitive screen, does it not help when you go to settings -> touch and then change sensitivity to normal?
