Has anyone had this problem since that "display+touch" update a few days ago? So far, mine's been behaving well, even after I turned automatic brightness back on. Early days yet, but it sure would be nice to think it's fixed. This is the longest it's been working for me in quite some time.
I don't know if the root cause is a hardware issue, software issue, build quality issue or some combination of those, but there are at least two software workarounds I can think of that will resolve the problem:
1. IF (a voice call is active AND screen is blank AND user presses the lock button) THEN (activate screen, disable proximity sensor UNTIL (call ends OR user pushes lock button)). This could be optional behavior, to accommodate those lucky souls that don't suffer from this problem.
2. Have a display option to not use the proximity sensor at all during calls.
That said, mine is still working after the last display+touch update, and I am with no particular evidence hoping that those two things are related.
Having the exact same problem. My phone has been back to Nokia twice already and is waiting to go back for a third time. It seems they just clean out the dust and don't fix the problem. Their support has been extremely unhelpful in getting the problem fixed as all they suggest is to send it back again for repair. So far I've been without my phone for 25 days due it being repaired and is still not fixed.
Don't expect this poor service for a flagship phone that I've spent lots of money on.
To me this is simply unacceptable that Nokia is not handling this better. This is not a new issue, this is something that is occuring on many devices across the globe. How can a phone be functional if the phone aspect doesnt even work properly? I have had to power off my phone just to end a call or wait uncomfortably for the other person to hang up. As a company trying to show the world that they are still relevant and ready to be a global competitor this service and this phone so far is a mismanaged mess. Nokia, wake up.
Yep, this sure does seem to work. Either use your own air or use some compressed air, like I did. If you hadn't noticed, the front facing camera sure does accumulate dust.
Ok.. after shipping my phone off to Nokia Repair Center for the second time, they sent me a shiny new one. This one appears to be working great, and not having the issues w/ proximity sensor / dust... at least not yet. I've had it for about a week now, and I've been checking closely to see if dust appears to be accumulating, and to date, it is not ). I was fortunate to have both a spare phone, and an AT&T Store right down the street (which swapped my SIM card out/back to my old Samsung Focus). So, I got the replacement 920 after about a week, and all is well. I still love this phone, but am still a bit nervous that the issue may come back. Although I do believe I was noticing dust within the first week on the old Lumia 920. Kudos to the Nokia Repair Center in Fort Worth, Texas for doing the right thing. Sounds like they may be starting to at least acknowledge the issue!
Same story here... On my 2nd 920 after 1st replaced by Nokia Care under warranty. Sent me a refurb. Can live w/o the FFC, but the proximity sensor?!?!?!? No dice, Nokia! About to send my refurb replacement unit back to Nokia Care as it's still under warranty, but **bleep**!!! Really lame and annoying... A flagship???
I'm having the same problem with mine here in Norway, I have sent my 920 in two times and now it has just gone a week again and the proximity sensor is starting to get the same issue...
OK, two things, one, thanks for that link to wpcentral, I need to pick up a few extra sizes of Torque screwdrivers and i'll attempt to fix the issue by opening it up and vacuuming out the dust + adding some foam around the missing areas over the weekend. Also on that link it said that there's now a team looking in to it which is good Finally, Nokia seems to be rolling out a new update which deals with "improvements to auto-brightness," anyone know if it could be related? http://www.neowin.net/news/nokia-rolling-out-updat
I've got a good feeling that vacuuming/wiping all that dust out though will fix the problem, so it seems we might have a permanent fix (at least for the people who are having problems with dust)
I'am also experiencing exactly the same!
Do you notice any change in beaviour if you tap the Power/Lock key as this sometimes brings screen back momentarily upon mine?
@aspergerguy. good point. I thought I had posted that here, but forgot. When I press the power/lock button twice, I get a very very short glimpse of the on-call screen. If I'm really quick I can hit the end call or speaker button.
If I hit the speaker button, and the call is on loudspeaker, I have full control again.
Interestingly enough, I tried it with bluetooth again, and the screen locks as if I'm using the phone noramlly

Gave my Lumia 920 for repair at Nokia care centre. I was told that the unit would be sent to L3 facitliy and that I would get it back only after 7 - 10 days. They gave me a standby set - Lumia 610.
Two days later, got a call informing me that my set has been repaired. Apparently, the unit had been cleaned and sensor was working flawlessly. There was no dust on FFC as well. However, over the next couple of days, the following problems surfaced:
What they actually did to the phone is anybody's guess. So I have given it back again today and have asked for a replacement. This should take another 10 days .
To me, it does not make any sense...simple cleaning resulted in these two far serious problems. What is wrong with Nokia support???
Will update the forum once I get the phone back...
