So recently my Nokia Lumia 920 screen crashed and all I see is a mix of colored pixels on the screen and I can't do anything, can't turn it off, what should I do?
First start by holding the power button and the down volume button both for about 20 seconds to see if it will power off and restart. Then post back.
That is weird that it froze with the colors on the screen. I have had a couple of crashes in the almost 3 months I have had the 920 every time the screen was black. I haven't had any lockups sense the Portico update. Have you updated yet?
Was it like a "white noise" screen? I got that once, after using the phone for about a week. I was talking on the phone while it was charging (from a regular electrical outlet), and it got quite overheated. When I was done talking and put the phone down, it looked like that. Had to google how to soft reset the phone, which thankfully helped.
Hasn't happened to me since, but I'm having regular (pretty much daily) problems with the phone just restarting - typically that I take it up after not having used it for a while, and the screen is all black just saying "Nokia" in white text and nothing happens. Have to soft reset the phone every time. Also, from time to time, it will prompt me to enter my PIN-code. Weird indeed.
