Blowing air into it seemed to fix mine for now. I actually used a can of computer duster in the earpiece and speaker port like someone had mentioned. Phone seems to work fine now.
My nokia lumia 920 is a great phone except for the problem of the screen going black when i make a call. Now onto my second 920 and the same problem occurs, Nokia i am getting very **bleep** off, but reading everyones posts about blowing into the sensor i decided to blow full steam with a hairdryer, problem fixed, ah nothing like a perfect blow job.
Nokia or the phone carriers should put in place a quality approval mark for cases that they sell as I have just been sold a case by Phones4u which causes this issue on a brand new 920 with, I hope, no dust mucking up the sensor. Don't buy a case which looks as if it has all the right holes yet covers up the screen just above and to the left of the N in the Nokia logo, unless you want to take the phone out of the case each time you make a call.
Had the same problem with the screen not coming back on. Canned air fixed the issue by removing dust.
One can only imagine that the wireless charging pad alot of our phones lay on at night are adding to the issue. It's there for 8 - 10 hours a day just facing up collecting dust.
I had the same issue with making calls. For me the problem disappeared (for now) after changing the setting for display + touch – touch sensitivity back to High ( I had it set to Normal ). I played with other settings, but this did it for me.
Hope it helps.

Yes dust getting in through speaker vent is the culprit, blowing air is a temporary fix as it remains to accumulate further over proximity sensor. I don't know if this is a batch problem or all 920's are susceptible but I feel mine will have to go to Nokia care centre for assessment and sorted. This is a manufacturing processes /design problem, if not already fixed at source it needs addressing as phone is not fit for purpose otherwise.
personally I would like mine replaced as it is just the best phone out there at the minute.
Blowing, touching, messing. Nokia....what is your stance? Nice customer service and manufacturing. What is your testing process? I like my phone and want to keep it, but it is a phone and if I can't use it for that I can always use something else.
BTW - tried them all, except using computer blower....love to just carry that around with me. So stylish.
just got off the phone with an at&t rep. she had me press & hold the volume & power buttons until the phone vibrated - took about 20 seconds. this brought the screen back to light as it re-powered on the phone. she said do NOT press & hold the volume, power, AND camera as this resets the phone. Then she had me look for updates, which it found - she said Nokia released a new update supposed to solve this problem yesterday or early today, but she didn't know exactly when any specific user would get the update automatically. my phone is still downloading updates right now, so i'll see if this happens again. I do a lot of dirty, outside maintenance work for clients, so am constantly exposing my phone to dust & dirt. I'll blow it out, now, on a regular basis, now that I know this is a source of trouble. And,hopefully, the new update will cure the problem, otherwise.

well, i have the newest Update of WP8 in my Lumia 920...
i cant end a call normaly. The screen stays black when remove the phone from holding at my ears... i can touch the screen several times and press other keys with no reaction and the call is ongoing. When the other side cancles the device seems to be alive again...
I had the same problem with my yellow Lumia 920. After reading this, I tried many things, and the one that worked for me is relly scrubbing the top of the screen where the sensor is till its super shiny. I think even the oil from your fingers affects the sensor...
