How dust gets inside your Nokia Lumia 920's front facing camera

The Windows Phone Central Forums are a place of immense knowledge, resources and camaraderie. There is no better place on the web to hang out if you’re a fan or user of any Windows Phone device. Here is some proof of the kind of content you’ll find inside – this is some Sherlock Holmes level work regarding dust, the front-facing camera, and the proximity sensor on the Nokia Lumia 920.

Forum user Eric Ewing (eeewing) was having some issues with dust working its way into the device and right onto the front-facing camera. Here’s his story and what he found while trying to fix the situation.

His first Lumia 920 was replaced because of the dust in the camera, which could easily be chalked up to problems with being an early production right? Not quite, as his replacement unit started having the same issue.

Communication with Nokia to fix the second handset was fruitless. He started with the support team on Twitter which wanted him to follow the normal repair process – the one that leaves you phoneless for about two weeks, which isn’t satisfactory in the least. Mostly because other members in the forums have reported all they do is take a can of air and blow the dust out for you. He then reached out to Matt Rothschild who passed him to the Nokia Care Team, where Eric learned that the issue was not covered under warranty. He then reached out to Stephen Elop (some members have had success in the past) and did not get a response there.

Frustrated with the situation, Eric decided to be proactive and attempt to fix the issue himself. This is what he found.

At the top of the phone, there is a seam about 1/2mm tall that runs the width of the device. It is located where the glass and polycarbonate housing meet. It’s all sealed except for one part, where the camera sits. The images below illustrate what Eric found.

Lumia 920 Dust Gap

In this image he illustrates where there is a cutout to hold a rubber gasket. However, the adhesive holding the rubber gasket is only sealed on the sides and bottom – not the top. That creates a slight gap where dirt, dust, and other debris could potentially enter the front-facing camera, something that a lot of members in our forums report. I myself have dust in my Lumia 920 from //BUILD and have had issues with my proximity sensor since December. It's maddening to try and make a phone call and not have access to any of the options on screen.  The image below shows the gap above the front-facing camera a lot better.

Lumia 920 Dust Gap in the dark

That all being said, even though they are right next to each other - there is no way for dust to enter the proximity sensor. I couldn’t really believe it either. But Eric found that the proximity sensor and front-facing camera are separated by a wall and sealed up tight, no way for dust from the camera area to work its way to the proximity sensor. So what’s causing proximity sensor problems for users? Your guess is as good as ours at this point.

Understandably, Eric is disappointed that the warranty doesn’t cover dust in the front-facing camera since it appears to be a manufacturing error that is causing dust or dirt to enter in the first place.

Update: After publishing this to the front page of Windows Phone Central, Eric was contacted by Mr. Elop. The email stated that his team will look into the situation. Eric will update all of us if anything noteworthy takes place. Until then. 

Does anyone else have dust under their front-facing camera on their Lumia 920? Any other theories as to what causes issues with the proximity sensor? Still think its dust related? Sound off below.

And thanks Eric for your contribution to the Forums!

  • I'm having the same problem...
  • well - who doesnt? Shame Mr Stephen Elop will not contact all of us :) 
  • Not I. I've had a bumper case on my 920 most of the time I've had it though.
  • You'll probably find that if you push down the top right of the screen, where the ff-camera is, the proximity sensor will stop acting up but you have to do it every time you want to access the in-call menus. This is due to the sensor being loose from the screen or something similar, hopefully Nokia will be able to fix this issue with a firmware update rather than having to replace the phone.
  • I really enjoy my Lumia 920 and the only issue that bugs me is the proximity sensor issue while on the phone. Makes for a disappointing experience, very dissapointing. I started off in December on the Lumia 920 and the issue appeared in January. I have been learly to pump air in the phone and the issue has progressivly gotten worse. I just tried pressing down on the top of the phone on the top right of the screen and the keypad apears. vThylacine.. Thank you for the suggestion. I don't want to replace the phone and also hope this issue will be fixed with a firmwsare update.. I wish Nokia would admit the issue and keep us posted on the fix.
  • Thank you very much vThylacine.  There had been dust accumulating in the FFC since buying my 920 when it first came out 18 months ago (cleaned it a couple of months ago), but just started having problems with my proximity sensor for the first time last week (trouble getting a screen to hang up calls, glance screen not activating, etc).  I had thought it was related to dust again, or possibly from the WP 8.1 Developer Preview, but following your adivce, gently squeezing the upper right of the screen (right on the "NOKIA"), the proximity sensor started working again (don't know how long it will last, but at least I have a temporary fix now).  Obviously, the device is well out of warranty, and there doesn't appear to be a wealth of Lumia qualified repair techs in my area, so if the fix truly ends up being temporary only, I may have to let my 920 go (to my son, to replace his 4 yr old WP 7 device). Your posting seems to be alone in its ability to pinpoint the problem with my proximity sensor.
  • My 1st 920 that I broke my own fault (along with 2ribs slipping on ice and getting hit with a case of beverages) did not have the issue, the 2nd which is a refurbished one does, actually showed up on my door with dust in it, but I have yet to bother with anything other than a quick hit of compressed air which solves it each time I notice it has accumulated
  • I'm more worried about you! Are you okay after breaking those 2 ribs?
  • Lol yeah I'm fine, wife and I were getting home from the grocery store and I told her be careful the ice is really slippery, had a case of beer in each hand and like a cartoon I slipped, landed on one case breaking open a couple with my thigh (and left a bruise the exact shape of the top of the can pull tab and all lol) and the other hand I launched the case into the air straight up, I remember landing in so much pain, and having the sensation of the cold wetness, and of coarse hearing her laughing, opening my eyes seeing the case falling from the sky hitting me square in the chest, and my phone was in my shirt pocket.. All the wind I thought I owned ppppppppwwwewww! Lol next thing I heard was the phones screen cracking like spidered tempered glass lol I laid there for a bit, got up and used the phone to call at&t, 1st time the extra insurance ever was needed for a Nokia for me lol
  • I reported this here 3 weeks after the launch and requested to have it added to the list of known issues. Even posted pictures of the gap. Canned air worked for me and continues to work for me. Even created a video. Elop didn't contact me.
  • My guess is that everybody does, its only a question of time since purchase :/
    I'll probably remove my screen, seal that hole and do something about those way-too-bright-for-watching-videos LED's behind the buttons. After that, the phone will feel less like a prototype.
  • This is merely a programming edit I don't know how they did not think of this Who wants buttons that are bright as hell next to a screen that you are focusing most likely in the dark. I say programming because the lights behind the touch buttons (digitizers?) change based on ambient lighting and if the same is applied to turning them off completely when a video is playing, then that is a simple solution via software rather than hardware. I realize your post is a year old. I too have problems with the front facing camera and the noise cancellation problem.
  • Hi, here: is the huge number of comments about this problem. I'm from Poland I had the problem with dust and dark screen - after blowing all is OK (since two weeks)
  • Hi, I'm from Poland, I had the same problem with dust and black screen during calling. Here you can read some interesting advices:
  • Yep, actually replaced my 920 through ATT because of dust under front camera. Though it was quite a hassle, so your results may vary.
  • I also replaced my white one through ATT, the only hassle I had was convincing them to give me a black one which worked :)
  • Ha, I have this problem as well, but was considering swapping my black one for a white one. Why did you want to switch from white to black, if I may ask?
  • The gloss kept slipping out of my hands and since I volunteer at a horse stable it didn't exactly work out, plus I love the way the black looks :)
  • <p>mine 920 too get hot vry fast nd frnt camera got dusted too...... help?? can i get replacement from nokia care centre?</p>
  • Like they say, once u go black, u won't go back.
  • Ell o ell
  • You really find the gloss more slippery than the matte finish? I have experienced very much the opposite. It's a big part of the reason I'm thinking about switching from black to white.
  • Yea wearing gloves makes a huge difference and like I said I work at a horse stable so we wear gloves a lot
  • Knock on wood: haven't had any dust yet. I bought my 920 on 12/26.
  • +1 No dust. Bought on Day 1.
  • My girlfriend and I bought ours a few weeks after release. I've had mine replaced recently and I have a bunch of dust in mine. Hers has yet to be replaced and she has no dust in it. It doesn't seem to affect the camera quality, though, and I barely use it. I just don't like seeing all the dust in there, it just looks bad.
  • No dust in mine at all neither. I also dont have any cases on it 
  • Wow even a dustproof Otterbox case can't fix that...
  • I had the same problem and replace my last l920.
  • Same issue. At first it was just the FF camera, but the proximity sensor stopped working on phone calls and went crazy with dimming. Bought some compressed air and it fixed the proximity sensor issue, but the dust stays in the FF camera. I also have the issue where the bottom right corner of the gorilla glass sticks out about 1 mm higher than everywhere else.
  • Get your phone replaced.
  • Had the same issue, blow compressed air into the ear piece, it will fix it. It really does work.
  • I figured that's where the dust is getting in. I'll try the compressed air in a can. No wonder my phone keeps going in and out of dim.
  • Don't blow compressed air in there... There's nowhere for the dust to go, just carefully vacum the gap above the sensor and ffcamera. Worked for me, got the sensor working after it been frustrating me for weeks now. :) I'd recommend you don't vacum the earpiece, just feels a bit risky...
  • Immediately after finished reading your comment. I stupidly, unconsciously taking risk blowing my mounth (wet) air around the ffcamera and proximity sensor problem ceased. But still see a dust in the ffcamera
    But for others, please DON'T TRY THIS ON YOUR PHONE unless you really know what are you doing.
  • I checked my phone after reading this comment...
    Yes! My bottom right glass is also sticking out by 1 mm (it goes in if I press though..). And yes my FF camera got a lot of dust under it! Related??
  • That's so funny. After reading your comment, my 8x bottom right glass is also raised a bit. But won't go in when I pushed.
  • Mines is good
  • Got dust inside and sent to nokias repair station without a long term solution in success. My sensor is no more working after a pair of month....! Frustrated too.
  • Tried computer duster and partly worked, then I dismantled the phone and built a new shield out of a different material
  • Mine comes and goes
  • Had this problem with my first and second 920's :/
  • I also had my original 920 replaced due to dust behind the front facing camera. The proximity sensor was also starting to not work correctly. Oddly, my replacement also collects dust behind the front facing camera but the proximity sensor is still working fine going on 2 months now.
  • Same here. Sent mine to Nokia as it was driving me crazy to end calls. The replacement has a little dust but not prox sensor problems
  • I sent mine in to Nokia Care in Singapore and they fixed it... no dust a month later. The Care Centre here claims that they can fix it and reinforce the seal... Not sure how but so far it's working for me...
  • Yeah I apparently have some dust pockets.. My proximity sensor is bad to.. I fixed it once by blowing some air in the ear hole. But now I can't fix it again. This is my second one that has had this issue. The first time I thought it was software related so I reformatted but that bricked my phone and I was with out for two weeks.. I ended up just buying one to tide me over and returned it when I got my replacement back.. Cost me 35 bucks but oh well... Now this ones doing the same thing. Absolutely love the phone but I don't know how much longer I can deal with not being able to tap a button when the machine asks for it.
  • I'm having the same issue with my white lumia. I use a compressed air can to clean the area. Maybe over time as dust accumulates more and more and starts to show up in your pictures Nokia will do something about it.  
  • I have dust under the original 900, and my replacement!! So tacky...
  • I hope the verizon variant doesn't have that issue
  • I've always thought it was a static build up from the wireless charging that attracts the dust to the top of the phone.
  • The wireless charging coil actually sits in the back of the phone, dead-center, right behind the battery. I only found that out, of course, when I opened the phone up, but I don't think it's attracting dust. :-)
  • Mine has dust. Currently on my third replacement. So far all the returns they've sent me are defective. Ridiculous!
  • Refurbs*
  • Same problem here with both the ff camera and the proximity sensor is just terrible too. I love the phone but if I can't use it as a phone then what is the point...
  • i took my lumia 920 back within at&t's return period.   i bought it at launch, and took it back after a week.    multiple problems. dust under the lens.  battery very hot, while using.  very poor battery life.   used it with a macbook pro.  i payed extra for internet connection sharing, and that didd't work for more than 30 seconds, then you would have to restart the phone's software... the phone reset itself about 4 times on top of several app crashes.  the software stopped syncing with my mac.  any time i plugged the phone in it would crash the sync application, (syncing with the app was the only option for using it with a mac pro).  this phone was so terrible i had to take it back.   there was little to no support.  couldn't call nokia, couldn't call microsoft. And at&t thought i had a defective phone.  i took it back to the store and got an iphone 5.   
    want to know how many issues i have had with my iphone since i had it?  ZERO...   i have had the iphone 5 for like 3 months. 
  • Wow.. Smh. Gtfo of this website bro!
  • +1
  • Good day isheep. Glad you enjoy your sissy phone. ;)
  • These types of posts crack me up. A simple google or bing search will reveal many issues with the iPhone 5 that a good number of users are running into: light leaks, easily scratches, SIM card not reading, poor WiFI radio (sometimes works, sometimes doesn't), poor battery life for a good number of users, and how can we foget Maps. There isn't a phone made that one can't go to a forum and find tons of issues for. There are tons of 920 users who have no issues with their phones, just like there are tons who have no issues with their iPhones. This is the reality of building products in China and using users as beta testers.
  • iSheep.
  • I'm on #2 with dust. Going to wait until it gets worse and then warranty it with AT&T. Got dust within first two hours in pocket. WTF!!!?
  • My launch day 920 got dust under its camera and proximity sensor within a month. I've seen replaced it buy my Note 2 has been my primary phone since, using the 920 for only about 10 days in the path 3 months, so it hasn't developed dust yet.
    I set up a survey a few months ago regarding this issue. Many people are reporting dust under their screen but proximity sensors that work fine, but everyone with a malfunctioning proximity sensor has dust under their FFC. The two have to be related. Complete Survey View results  
  • I've often wondered if the blast of air to clear the camera window pushes on the proximity sensor tape connector (encouraging it to pop off).
  • I had the same issue on a phone I purchased on day one at AT&T for my Lumia 920. Took about 3 months before I noticed the build up of dust behind the front facing camera, and then about a month after that the proximity sensor started having issues. I went to AT&T where they proceeded to tell me I got my phone wet and it was moisture behind the glass and I had to push really hard, reference the forums and basically plead my case. I think this is an area Nokia should take notice and get in front of. This could end up being a PR nightmare long term if they don't address and resolve the issues for customers. I have to say the phone quality is top notch, better than any previous phone and day by day the OS and apps keep improving. Look forward to year two and the future it holds. I also have had a TPU style case on mine and the it looked like new when I got it exchanged.
  • I had it with my 1st yellow 920, then got a replacement (reconditioned) from ATT. Haven't had the dust problem, yet.
  • Aww man I've had both these problems. I was told to reset the entire phone by ATT
  • LOL!
  • I have dust on the ffc and I've had problems with the proximity sensor. However, I believe the problems with the proximity sensor are software related more than hardware. For when I switched off the authomatic brightness adjustment the problem went away and hasn't returned since. So my guess is bad sensor calibration on Nokia's behalf, something that wasn't noticed on time to be in Portico. I'm therefore hoping Nokia fixes this in the upcoming GDR2. I recall the first Lumias also had sensor proximity problems in the beggining (my Lumia 800 had), something that an update resolved. But the dust is frustrating. However, I seldom use the ffc. So it's the least of my problems.
  • I do not think so. Everyone with proximity sensor issues has dust under their FFC. My proximity sensor didn't start malfunctioning until I got dust under my FFC. They have to be linked.

  • Apparently everyone has dust on their ffc. However, as it says above in the article, there's no way the dust can pass to the sensor. Therefore the only logical explanation is a calibration one.
    As I said, I no longer have any problems ever since I turned the automatic brightness adjustment off. Yet I still have the dust on the camera. If the problem was with dust in the sensor, turning brightness off wouldn't change a thing since it would be a physical element that was causing the problem.
  • Well, whenever I get a blank screen preventing me from hanging up at the end of a call, compressed air along the top of the glass has cleared away the problem. There was supposed to be no way to break the glass on a Lumia 920 also.
  • Yup, having the same issue with my Lumia 920. Both dust in the camera and Proximity sensor issues.
  • i have dust under the camera. reserved on first day, yellow 920. what i think is some type of liquid cement could fix it.
  • I have one little speck of dust on my ffc after two weeks of usage.
  • Yep. Got dust bits in the front camera. The sensor is fine and working well though. I don't use the front camera much, but seeing dust in there and in the ear piece is annoying, so I use a vacuum cleaner lol.
  • My first 920 had the proximity sensor problem and tons of dust under the front facing camera.. Replacement has been good on both fronts thankfully..
  • One of my coworkers is on his third iPhone 5 due to manufacturing defects. The first time was a bad display, I forget what the second problem was. Point is, even apple has production issues. Antenna anyone?
  • And this is relevant, how?
  • I have dust under mine, and canned air doesn't seem to help anymore. I don't really use the FFC much, but it bothers me that Nokia won't cover this issue under warranty. It also will affect my phone's resale value down the line and I'm displeased about that.
  • No dust nor problems with proximity sensor for me and have had my phone since launch in November. 
  • Clearly a Manufacturing?design defect. Nokia should make a replacement gasket and just fix them. Where's that Commitment to Customers that they showed with the 900 ?
  • People use the ff camera? I've never used it once. Wouldn't know if I have dust.
  • Unfortunately the same issue affects the proximity sensor, which everyone who makes calls uses.
  • I also have dust in my Lumia 920 front facing camera, and I'm also worry about, dust could damage my phone :-(, is there any solution?
  • God.... I'd love to replace my 920. I have the dust issue, plus the unresponsive freeze requiring a soft-reset issue. Unfortunalty ATT customer care is such a pain in the &@&%$%#$& to deal with. Bunch of incompetent fools they are.
  • I too have dust in the front camera.  My phone is also from //Build
  • I get dust in my ffc but it doesn't affect the proximity sensor, still annoying though. Every few days I use can air and it gets rid of most of the dust. do you think it will get worse over time? that would suck.
  • I have dust in my FFC but my proximity sensor works fine. Not sure what could be causing problems there.
  • I already replaced one phone.. Even this new one also accumulated with dust particles :'(:(
  • I've had dust in my Lumia 920 front camera for as long as I can remember, certainly within a week of owning it. Since I don't use the front camera often it doesn't matter a lot but it looks awful and is frustrating.
  • I have replaced two phones because of the dust in the FFC through ATT's Device Service Center.
  • I love to say it, my Samsung ATIV S is flawless and battery lasts a day and half with heavy use including all the bells and whistles on. The only thing the 920 has up it is the main camera. I feel for you folks, I feel worse that I've never met another windows phone user in real life.
  • Go hang out at the local Microsoft store, haha! That what I sometimes do..
  • Its sad but true :( I'll go tomorrow,
  • I have an 820 and not many have that about that I know. My 820 while it has been faulty, it doesn't have the prox sensor or ffc dust issues. Yay for different handsets.
  • Wow, that's some Sherlock Holmes s**t there boo boo.
  • Mine had dust, I was able to blow it away though the earpiece.
  • I also have the dust problem. Did the Nokia send in. They cleaned it. Dust is coming back. VERY disappointed in Nokia for not standing behind this kind of manufacturing defect. I mean, how can dozens of their employees tote a 920 around and not notice this???
  • Don't you know: There is no such thing as dust in Finland. They are dust-proof, like the Sports Almanac in Back To The Future 2. Duh! :P
  • Dust in mine but not my wife's or my mom's. Maybe its a sliding in the pocket thing. There's are never in their pockets.
  • Wow. For the first time yet I'm glad to have my HTC 8X instead of a 920, lol
  • I had the 8x first and if it wasn't for the inferior night time shots and sound recordings at concerts etc I would still have it as I think the 8x takes sharper pictures in daylight
  • As for the proxy sensor. Anyone else notice the matte finish around the camera and proxy window? And also the bottom left corner below the back arrow. It looks like maybe its the anti friction coating. And they didn't want it to interfere with the image quality or the proxy sensor maybe. Maybe there is some internal reflection that catches the sensor. Is there a wall between the 2 parts of the proxy sensor? That may be the problem.
  • My 920 has dust in the front camera, getting worse.
    The proximity sensor errors can be caused by a screen protector if the protector actually covers it. This is due to the curved screen generally creating a very small gap along the edges and messes with the sensor. Gets worse if dust builds up in the screen protector gap. I had to cut away the sensor portion of mine and I no longer have an issue.
  • +1 dust here too
  • Yeah I had mine replaced because the prox sensor was shot. Also had a ton of dust under the front camera. 
  • Don't have any dust issues, but somehow there is an eye lash under my glass above the screen. It is in the side of the screen and is only really noticeable in bright sunlight and only barely sticks out over the actual screen.
  • When the 900 came out.. It did have proximity problems but after minor update my 900 is perfect,even though I was really tempted to get the 920 I felt like my 900 is SOLID!!!
    KEEP TWITTING @NOKIAUS they always respond
  • My son Replaced his Red one through ATT... Big time dust issues...sent one out right away.. Sucks they sent a black one to replace it :(
  • Poor eric :(
    I had the problem with my Lumia 900 and suffer like eric....mobil less for more than 10 days.
    Nokia should offer premium services for their premium customers like Lumia 920 and 820 buyers.
  • Sending my 3rd 920 to Nokia this week. They better not send me the sane phone back.
  • Still rocking my launch day 920 with only the rare problem. No complaints here.
  • Yup. I have had two and both quickly built up quite the collection of dust behind the glass of the front facing camera. I never use it but it sure is annoying. When it starts to fill up the proximity sensor and cause problems, I'm gonna be pissed.
  • So far I have this issue, but nothing seems to be wrong with my sensor.
  • I'm having same problem here but after cutting screen protector above proximity sensor my 920 working perfectly.
  • Yup, did the same and it worked. But still the dust under the FF is very annoying.
  • Sorry for the silly but what is the purpose of proximity sensor ?
    I put my 920 in a case with magnetic clip nearby the FF Camera and ear Phone plug. Will that affect the sensor ?
  • I think the main use of it is that the phone screen turn off when the phone is near your ear so you don't press buttons by mistake when you touch your ear with the phone.
  • Had proximity sensor issues and dust on ffc, sent my 920 to Nokia for repair, got the phone back and the sensor went again a week later, sent it back again and Nokia replaced the phone, so far so good
  • Yes but I use air hoses at work wen I do the I'll feel all edges blow out air and the glass raises during but wen its all done the phones not damaged and still the toughest out
  • Dust on two units over here. It does look tacky.
  • I have exacly the same problem...
  • Could it be related to ATT Lumia 920? I own a international one with non of those issues.
  • Same problems in Finland..
  • Made in China. My Lumia 920 is also all but reliable. Most of the stuff that is made in China has some major flaws, no matter what brand. Only way to get quality is to not buy stuff that is made in China.
  • I've had three Lumia 820's. Two were made in china, after both suffered the same constant rebooting etc and a couple of emails to Mr Elop, I've managed to get my third one as a Made in Finland handset. No issues at all.
  • How is that possible.. We don't make phones in Finland anymore :D Or that's what we are told
  • My 820 heavily dusted, has same issue. But, I can't repair or replace, becuase I'm imported from foreign country this one...
  • HA! FINNALY KNOWN (ups caps lock accidentally turned on) so. My 920 has a small dust in front facing.... But i dont want replace my phone D:
    This is My Favorite phone. Dont want to replaced with same version. How to remove dat dust in my 920? Please nokia, give little service by adding selaed tape in front facing.
    *sorry bad english*
  • Same problem. Terrible design flaw for such a beautiful phone. Hopefully when they decide to fix the error first gen 920 owners can get an upgrade.
  • Exactly the same issue, heavy dust build up on camera and proximity sensor never works, make a call and screen instantly goes black which has lead to some very embarrassing voicemail messages indeed :/ I don't have the means to get it replaced as I cannot be without the phone as it is currently my only source of internet.
  • I have dust in my front camera as well but it doesn't seem to be an issue with the proximity sensor or even picture quality. Only a cosmetic issue to me but im the only one that would ever notice it anyways.
  • I'm going on my fifth Lumia 920 replacement after getting an response from Stephen Elop (via email). The support is amazing, and the response is fast (like next day/overnight shipping fast). Unfortunately, every phone I've gotten has had this issue. I guess I'll be sucking it up though, and sticking with what I have.
    I probably sound silly saying it, but I truly love this phone too much to switch to another model. I can live with the dust I suppose -- especially since I know it's inevitable with whatever replacement I get.
    Thanks Eric!
  • Sadly had the dust issue also on my white 920. I called AT&T and they happily exchanged it (touch wood) 3rd week in with my new unit and no sign of dust. Just have to say, even with the dust issue, what a kick ass phone. Nokia has set the bar high for me, don't think i could go with anything else now.
  • I've been used Lumia 920 for 3 month. I knew that I'm in Beijing, which has a lot of dust in the air. But it's not expected to have it in front camera of your cellphone! I may use the tool to clean it by myself.
  • I have found that the smallest amount of smudge on the glass by the proximity sensor causes it to fail .. I simply wipe the glass clean and it starts working .. It is not dust
  • Would a tiny drop of superglue fix the issue ?
  • Yep! It actually would require either gluing the internal gasket down (which is what I ended up doing) or gluing along the gap (across the entire width of the camera opening) in order to seal it.
  • l also had a proximity sensor issue. Used a vacuum cleaner on high all around the top of phone and all good ever since!
  • This was a problem in the initial batches (another reason to not be an early adopter) and is now fixed.
  • Not according to other commentators who have second gen phones.
  • Like many others, I replaced my handset due to ffc dust build up. I could live with the weird rattle when it vibrated and other little niggles, but I have to say, the replacement handset is a different phone. No dust, no rattle, no screen freezing every now 'n then, improved battery life, and less overheating. :)
  • How many fault and bugs on Lumia 920 are we up to? I'm having a hard time keeping up but it seems to go for a world record or something. Maybe time for a article about what is and what's not and what fixes to expect.
    Currently I wish I could play Spiderman, but you get burned by the phone.
  • If they cannot fix it with a system update they could at least give us a control panel to toggle the proximity sensor on or off! I'm on my second phone after receiving a refurb instead of my old phone back from Telenor in Norway. I thought it was a new phone at first since it had all the factory plastic seals all around it and over the camera, but it has a tiny scatch on the glass so it is a refurb. Anyway, Nokia told me they have a fix for it but the phone isn't sent to them but to someone called mCare. When the people at the repair shop fail to fix it in a better manner than by blowing air on it, they probably reach for their stack of replacement phones, refurbished for other issues. Telenor tells me that I simply have to send it in again. Which is strange as they probably have to pay mCare a lot each time. Two year warranty. If I send it in every month it would quickly amount to the cost of a few new phones.
  • First 920 i got had dust under screen glass out of the box and it was rejecting the sim card, second 920 i got the glass is sitting higher on the right side. I thought Nokia made quality products, don't get me wrong i like the device but ive never had any problems with Samsung over the years.
  • Really to bad that Nokia does´nt make an official statement about this issue! Mine is underway from a repair due to the proximity problem. During night when using my device in the bed the screen saver is also using 100% and other nights it worked as it should lowering the brightness. I don`t know what is wrong and it is even more strange that the problem is periodically!
  • same problem with my NL920
  • Same problem here. Dust particles in the front camera. Phone gets heated, just above the back camera. Dont know this issue is! Neither do I have any hopes with nokia service center to rectify or replace the handset. I think this is one more issue with the nokia service here in lndia.
  • have had this problem from the second day of usage. Thinking of buying torque screws, opening my L 920, and placing something to isolate the camera. Oh and the proximity sensor doesn't work anymore for me too -_-
  • Same Problem :/ Greetings from Germany :)
  • Same problem here with dust on FF camera. Issues with auto-brightness only since Protico, so likely to be software related.
  • I dont have any problems
  • I would suggest that Eruc and others go the extra mile and contact an ombudsman. Nu wrranty on this issue is nonsense. It is too rast for Nokia to dat something like that. I het the feeling the camera is redundant. But then MS necessitates a front facing camera for among other Skype. So this issue is serious. I think a collective complaintvis in order here. Gold luck!
  • Speaking for myself, I'm not sure the situation is serious enough to warrant that. While the problem is certainly annoying, it's not "serious" insofar as all it takes to clear the dust out is a can of air. At the end of the day, I don't want to "stick it to" Nokia or anything...I just wish the phone had the build quality that I'd expect of a top-of-the-line phone.
  • My lumia Was repaired about month ago. I had both problems - dust and proximity senzor disfunctionality. But Now It looks Like The problém Was solved. No dust after month, no problems With proximity and no problems With crapy vibration Noise..
  • I also have dust. Hasn't causes issues yet but I'm keeping an eye on it.
  • I had mine fixed. Just got it back yesterday. Was mega frustrating when proximity sensor was not working... Although less frustrating than the week i had to spend with an iPhone waiting for my Lumia 920 to be returned.
  • I've got a black Lumia 920 with dust all over my ffc, (lumia bought from EE store the end of Dec last year.
    I can be without my phone for 2 weeks while it's sent for repair, so don't know what to do (I've sent nokia a message via twitter, but had no response)
  • Got my Lumia 920 back from repairs for the second time yesterday. Both problems where related to dust under the proximity sensor.
  • same problem here. but as of now, don't care. may care once the other side complains while skyping. that hasn't happened so far.
  • Same issue. Nokia want me to send my phone in for a 3rd time! Ridiculous! I also have light leaking around the screen. I'm so fed up of it
  • Same issue here, dust behind the camera, but blowing air into the earpiece does appear to fix it.
  • Took my first 920 back to Telstra (in Australia) a few days ago to be sent off for repairs. The problem was dust inside the proximity sensor, under the glass. It's supposed to be a couple of weeks before I get it back, but to be honest I have no faith that the repaired unit, or the replacement, will be any better. So shocking to find a smartphone with such a glaring design fault. I don't know what should happen here, maybe Nokia should recall all the sold 920s like car companies do. Certainly won't be buying another Nokia if I have the problem again, and I guess that means no more windows phone either. I signed up just to post under this topic. Please do something about this Nokia.
  • My is the same, Australia Telstra user. Actually there's already a disucssion here:
  • I say this with all honestly and I hope people see this. Usually I'll just lurk around in forums, but I'll post this since it's the truth and I somewhat have proof if need (batttle scar on my phone) Anyways... I had an extremely dusty front camera, pictures came out in horrible quality. I also suffered from the proximity/black during call error. It was very inconvienient and made me hate my phone at times since I won't be able to hang up, add calls, look something up, dial keys, and etc. HOWEVER. 2 weeks ago, I was in the gym and while rolling up my pants to put in the locker, my 920 fell out. It impacted head on the upper right corner. I was concerned, it was a 3.5 feet drop and the internals of the phone sounded loose whenever I shook the phone post drop. Surprisingly, after I dropped my phone, I was able to shake the dust in front of the front camera to the side. Even MORE surprisingly, it fixed the issue of my screen turning black during a call. It's crazy. Simply crazy.
    tl;dr: I had the same issue, dusty camera & poximity censor black screend during call. Accidentally dropped it 3.5 feet onto locker room concrete impacting the upper right corner. Fixed both issues with possitive long term results (2 weeks). I don't know how, but the more your drop your Nokia, the better it will work. Go figure. Again I can't make this up. x.x I don't advise everyone to go out and try it since it may not produce the same results. But has anyone dropped their phone specifically on the upper right hand corner persay?
  • Same problem here, dust and proximity sensor.
    I'm surprised it's taken WPC so long to raise this issue considering how wide spread the problem is.
  • I had my phone repaired twice. First time it was beacause of shrieking body AND tons of dust under ffc the second because of broken speaker. The dust got removed but now, after two months its back there in huge amount. I've tried using compressed air to remove it, but it simply isn't working anymore. Unfortunately it was recently noticed by my coworkers (who are mostly using high end android devices) nad now I am laughed at :). They find it amusing I spent so much money on so poorly manufactured device. It really makes me angry when I compare my phone with my wifes's Lumia 820. Its quality is sooo much better... All these flaws took away great portion of fun and pleasure I experienced when I started to use my precious device... I really like WP8 despite some apps stil lacking, but as for hardware I find my Lumia nothing better then any other high end device around. Whats really cool is its camera, but we all have to honestly agree its only case in certain conditions...
  • Dusty dust dust my front facing is covered, its a blatant manufacturing default. I'm guessing one that is too costly to admit to?
  • I am so confused by this issue. What does "dust under the front-facing camera" mean? How do you know you have the problem in the first place? I'm not trying to be difficult, but I don't understand.  
    Also, were these pictures taken from behind? My proximity sensor appears to be to the right of the camera, which these pictures have to the left. 
  • "Dust under the FFC" is more accurately described as "dust under the glass and in front of the FFC lens." On many Lumia 920's (though certainly not all), dust is entering the phone through gaps in the housing and the fear is that it can cause image quality issues on the FFC, plus cause issues with the proximity sensor. Generally, it's just a problem that shouldn't be happening with a "flagship" phone.
    The sensors look to be a mirror image from what you'd expect b/c I snapped the pics from the inside of the phone looking out. What your seeing is just the front piece of the phone assembly (glass screen and housing)...all internal phone components are removed, as is the rubber gasket that normally sits covering the camera opening.
  • Thanks for taking the time.  
  • Nope no dust on my red Nokia lumia 920
  • Can someone confirm this with the 822? Don't want to worry myself.
  • Yep same here with 920, The sensor is working but my next phone wont be a lumia for sure.
  • get some compressed air and just blow it out from the top,  seemed to work for me.
  • I had same issue I blew into ear phone slot and it started working. I knew to do this as I had exactly the same issue with my iPhone 3GS. I found I was putting the phone top down into my pocket and in the bottom of my pocket sits dust after I bought a cheap sock to put the phone in I don't get any issue. Other than this m 920 has been flawless and would go far as to say the best phone and I've had a few and destroyed a few !!
  • Not a problem per se, but there is dust under the front facing camera.
  • I got mine replaced and still have the same issue. Im just gonna ignore it as i never use the front camera. The compressed air trick works
  • I too have the Proximity-sensor issue, as well as dust in the ffc.
    Nokia Care tried to repair (without providing a replacement unit, extremely annoying!), but the repaired unit now has the same Problem again. I contacted Nokia and my reseller again about the problem, but since 2 weeks got no reaction *at all*. To think that I recommended Lumias to other people >:[
    Nokia really needs to step up Support if they want to compete with the big guys :/
    Also, WP-central, please make your Nokia contacts aware of this thread and escalate. Thanks.
  • Nokia Sweden on Facebook confirms that Nokia now have developed a permanent solution regarding the issues with the proximity sensor.
  • Did they tell how?
  • The didn't say how they will do it
  • Amigo,
    Resolvi da seguinte forma:
    Desmontei o aparelho e fechei a lacuna com silicone.
  • Can't find it but I don't doubt you. In any case it doesn't help much if people already have phones with this problem and they aren't being repaired by Nokia but by someone else, which is at least the case here in Norway.
  • If you look at post by others you will find a thread concerning the proximity sensor. Nokia replyed by saying that they in a couple of days will come up with a permanent solution
  • That is a step forward I guess. I wrote Nokia and asked about it a while back and I was told that they had a fix for it in their repair shop. Which doesn't help me in itself since Telenor sends phones not to Nokia but to some private mobile service shop named mCare. And they cannot fix it. So I'm hoping for a solution in the form of a software update to tweak sensitivity. Or the option to turn the proximity sensor off altogether.
  • Could you please share the direct link to the above on their facebook page? I have looked but I did`nt managed to find it?
  • Search "Nokia Sverige" on Facebook.
  • Same problem here. Dust in ffc and proximity sensor not working. For example having to hung up a call by double tapping power button and then quickly pressing the screen is ANNOYING. Btw, this is my second Lumia.. Same problems as the first one had.. Greetings from Finland!
  • Have you tried wiping the glass by the proximity sensor .. Its locates just above the n in Nokia in the 920.. When my phone does that I just wipe the glass with my shirt and it works fine after
  • Yep, still not working. Tried all, blowing air and even pressing the upper left corner. That worked actually a few times!
  • Btw: My Display is full of 'light' scratches. My old NL800 doesn't have even one scratch, my NL920 has plenty of them. What about your Lumuas?
  • It's he top layer of wax that is scratched not he glass use ordinary furniture polish on it and they disappear that's what I found 
  • Lots of dust.  I also have really dry skin so that doesn't help at all.  I haven't had proximity issues.  I hope the next round of 920s or the next line of flagship phones resolves this.  Amazing phone minus that one annoying little quirk.
  • I'm using my 4th Lumia 920, all change with Orange FR warantly. The 1st had dust and proximity sensor issues, the 2nd, dust and the speaker was not working, the 3rd had dust issue and i'm worried about the one i'm using because it's sometimes turn off by its self... if someone does experiment this issue, please, let me know
  • Strangely enough I had the same problem but I used a can of compressed air right above it and it removed the dust. I do it now every so often to make sure its dust free.
  • I use compressed air every 3 days as my regular phone maintenance
  • i have the 2nd replacment and still suffer under this bloody issues :-(  
  • Oh noo, I decided to buy this phone yesterday.  I think I will go on with my 6 years old N73. Very upset now.
  • HTC....the phone is great.. A lil dust of FFC is not really issue, so much as issues that could affect proximity sensor...then it really sucks, however most people don't have prox sensor issues, just ffc dust which doesn't affect functionality
  • Wow! This all makes me hope that HTC brings something more to the Windows Phone world before my upgrade comes in June!  I've never been impressed with any of the NOKs I've had so they may not get the nod to replace my T-II.
  • Nokia has the apps going for them though, its not something to overlook anymore
  • I also have dust in my ff camera, though I don't have senor issues. Will try vacuuming that was recommended
  • I have dust in my Lumia 920 FFC, but I'm not not having any problems with my proximity sensor or anything else on my phone.  Not going to return my phone to AT&T for a little dust, but will if it malfunctions.
  • I have dust in mine, I also tried to get mine replaced and they wouldn't replace it.
  • I've got some dust in mine too. Was surprised to find it there. It is soo annoying!!
  • I got a Nokia 920 from Nokia for a 2 week trial and that had dust in the front camera, i was quite disappointed to find that.
  • I had the same issue on my launch day 920. Dust began appearing immediately and the sensor crapped out after a month. AT&T replaced it in a surprisingly simple process, and I've had no dust nor other issues after a month with my new phone. As for the sensor, one person posted a fix in the Nokia forums but it involved opening the phone and gluing a chunk of insulation foam in the area between the globe logo and earhole to create a more pressurized seal ... not exactly a simple affair.
  • Everything smells and feels quality except for those damb dust in my ffc! I'll try air but, shouldn't have this issue to begin with. I'll be looking forwward to the follw up to the article.
  • I have the same problem. My proximity sensor fails approximately once per week until I dust the camera with compressed air. I hope there is some way to fix this
  • Everyone complaining about the smallest of things. Dust? Bloody dust, fair enough if the proximity is messed up but dust ffs. Ive had my 920 as soon as it came out in the UK. I dropped it after 3 days, the side, top is cracked. But that's life. I have dust in the ffc but who cares, Stop winging and get over it. You'll never get a perfect phone. As long as you can call and txt, and now surf the net. The rest is a bonus.
  • Well, in my case at least, it wasn't the dust itself so much as the fact it seemed to indicate a poor build which could denote more serious issues (i.e. proximity sensor) that could crop up. So, yeah, I think "winging" about it is fair.
  • Ok 3 things:
    1- its not just annoying dust, if it affects the proximity sensor(don't care on ffc) and when many any call screen stays blackbits a big issue in the main functionality of the device..a"phone"
    2- the 920 is a top of the line product and should perform as such, its in competition with other top of the line products, and it should excel.
    3- why settle for mediocre?
  • It is somewhat annoying when you make a call and reach an answering machine, and there is no way to end the phone call. There is a long recording of you swearing and fumbling and grunting as you try to hang up. I think that a primary requirement for a mobile phone is that it can actually be used for telephony.
  • My ATT 920 has this issue too.  I have you all beat though.  I have to throw hay out to horses every morning and get covered in it sometimes when its windy.  My 920 has a chunk of hay blocking the ffc.  How that managed to get in there is beyond me.  I could care less though, never use the ffc.  When the the waranty expires I'll open the phone up and clean it out myself. 
  • My guess would be the headphone jack.  If you take a flashlight and look in there its completely open to the inside of the phone - total vector for dust and chunks of hay to get inside the top of your phone.
    I'm considering opening it up and sealing the open area with silicone, but don't want to crack the case open if it isn't necessary.  For now I'm going to put a headphone jack cover over the jack to keep that area sealed.  
    Makes me wonder if Nokia layed off too much of their engineering know how for such a stupid design flaw.
  • Yes my NL 920 also dust in front facing camera
  • I didn't have any dust until I read this article and noticed
  • This may be a dumb question but how can you tell if dust has gotten in your ff camera?
  • Use a flashlight to check for dust inside the front facing camera.
  • This is one of my major issues with this phone, the inability to hang up a phone call when it goes to voicemail due to proximity sensor dust. Its making me consider changing to android, especially if it's not covered under nokias warranty.
  • I am having those issues... And can of compressed air does help.... Cause I went from a total fed up proximity sensor and black screens when making calls, to the current erratic state ... Where I works 70% of the time....
  • Yes, it'll just stick to the glass, on the inside. I've had the same with mine but unfortunately it stopped working so got sent to the device support center where they tried to get the phone to actually work but could not. So it was under warranty and got a new phone. I though it was the skin that was causing the proximity sensor to go haywire but didn't know that was part of it.
  • I see a tiny bit of dust now.  Nothing thats really a deal breaker for me.  My samsung focus was much worse.  I had to take it apart and clean every 6 months.  I work in a dusty place.  I'm just hoping the the L920 won't be too difficult to take apart and clean.
  • Same here but no biggie to me. I use the back camera the most.
  • I've got the same problem.  Getting a lot of dust.  Once skype is more integrated into the phone I may use it a lot more.
  • I was planning on purchasing some lumias for some family there any way WP Central can do a poll to see if this is a widespread issue. I know that most of the ppl who are responding do have the issue so its hard to tell how many don't have the issue, so a poll would be helpful. Maybe if it can have an option with dust in front camera, proximity sensor issues, both issues, or neither issues. This would help me and probably tons of other ppl out alot. This can also be useful for Nokia to see an actual percentage count regarding these issues. Thanks so much!
  • This, this problem is keeping me away from Lumia 920.
  • I try and not put in my pocket as much though.
  • I had it in my 1st phone, which was replaced on-site within the 2 weeks at a MS store.  My replacement phone has it.  I strongly believe that if I buy something it shouldn't have these issues, but it's such a pain to get my phone all set up again that I gave in and just bought a can of air to spray it out on occasion.  It's been a livable fix, though a bit inconvenient if I'm travelling for work and need to clear it out, but don't have an air can. 
    Good to see Elop responded.  Hopefully they'll fix it for other devices. 
    My first phone had proximity sensor issues as well, but this phone has not
  • Forgot to mention...the dust for me is no biggie.  Just spraying it once a month is sufficient.  But, before i knew of that fix and the dust started affecting the proximity sensor...that was a big problem.  As others have said, you can't hang up because the screen stays black, and you also can't access the keypad during a call for the help line to report your issue.  lol.  Nokia's been good about service so far.  It'd be great to see some kind of good-will resolution with fixes for those experiencing severe limitations, and something small for those fighting dust.
  • AirSpraying and/or Vaccuming fixes the issue for me... (Yes, I have the issue too and I have been suffering from the first month I bought my Red 920). My friend bought a Cyan 920 and it has no problems...
    A longterm solution would be appreciated though!
  • just pain phone to Cyan
  • When I first bought my 920 I saw a spec of dust. It bothered me but it's not something I use. It appears at this point that the dust is now GONE. Whatever, I'll take it
  • Glad Nokia didnt make all WPs like this, my 810 doesn't have any FFC issues
  • I do
  • Although my speaker is full of dust, ffc seems ok. I was having bad problems with my proximity sensor. , couldn't end calls or dial options during calls. One day phone locked up completely. I called att and they had me do a soft restart and told me to do portico update. Since then my phone has worked perfect. My opinion is that sensor problem is software related. Lumina 920
  • No apparent dust but I am having proximity sensor problems, although, a soft reset appears to have fixed mine. For now at least.
  • Yes and its annoying
  • Same as the ohers with me too.  I compressed air'd it out and the phone works but I too have dim and brightness issues. 
  • Mine has dust extremely bad, I need to try the compressed air or take it in.
  • I noticed dust in mine a few days before this article and now today I realized my proximity sensor wasn't working either.  I used an air can and that seemed to fix it.  Kind of annoying, I was hoping this phone would last for 3-4 years since it'll become a hand me down after I'm done with it.  I wonder how long the air can fix will be effective for?
  • I received a replacement and noticed dust the notorious dust fresh out the box, darn shame I love the phone but since I'm well out of my 30 days I'm stuck with this issue for 2 YEARS!!!!!!!! :( :( :( MEEEE!!!!
  • I suddenly remember reading about someone claiming that turning on and off again the front camera sort of flashes the proximity sensor problem away for a while. Anybody try this? I just did, but then again I also blew into the speaker minutes before. The screen comes back on again now for the first time this week, but it could very well be just the blowing.
  • Yep dust
  • I have dust on my front camera and my headset sound horrible. During phone calls I have to used a head phone with mic, to avoid hearing all the crackles
  • Same problem here, dust in the ffc and many issues with the proximity sensor. I can live with the dust in the ffc but the proximity sensor is killing me. I can usually fix the sensor problem by repeatedly blowing in the gap so I'm almost certain its not software related.
    I've been through ATTs warranty exchange process 3 times with no resolution so now I'm in contact with Nokia support which couldn't comprehend the fact that i was unable to send my phone in for repairs because I use it for work on a daily basis. Based off what I'm reading from everyone else, sounds like sending it in for repairs rarely fixes the problem anyway. After finally convincing them I couldn't be without the phone, support said they would have a support specialist call me to resolve the issue, that was three days ago...
    Wish I wasn't such a loyal fan of windows phone 8/Nokia or this would be any easy fix. What happened to this world class Nokia support I've heard stories about???
  • dust dust dust... compressed air every other day and sensor issues keep coming back. i don't really mind the camera dust because i don't use it often, although it's very disappointing.
  • I had this issue after removing old carpet from my basement. I could see the dust on the inside of the glass. It took me a few days to realize I could get it clean with compressed air (like some other commenters). This was very fine dust, and I haven't had the same issues with larger particles (like wood dust).
    After using the compressed air, and being more careful around dust, I've not had the issue again.  
  • Dear Mr Elop ... your phone design is defective. I hope you can do something about it.
    I will defer my 920 purchase until this issue of dust and prox sensor is fixed.
  • I've got dust under my FF which I mostly 'pushed away' with compressed air. My prox sensor seems fine though.
  • Bought mine in December no dust lucky me I bitch about everything
  • I got dust under my glass in front of the ffc, and found it was entering through the speaker hole.
  • Had the same problem, emailed Mr. Elop. Was contacted 2 days later by the head of Nokia customer care Germany, got a new phone 3 days later, all works fine now without problems.
  • My FF camera is loaded with dust, and my prox sensor operates far from ideally.
    Where do you blow the compressed air? My 920 is a black 920 refurb, to replace my 920 that failed (battery failure)
  • I read somewhere that the dust from prox sensor can be removed by using a vacuum cleaner through the ear speaker (next to prox sensor) ......has anyone tried this?
  • not sure if this link will work, but here's the dust in mine
  • here is a photo showing dust in my Lumia 920
    http://<a href="" target="_blank"><img src="" border="0" alt=" photo 1c4ee036-0f44-41f6-92e3-a045a69526c4.jpg"/></a>
  • I'm another victim of dust in the front facing camera.
  • I am also having same kind of problem. Hope so Nokia will come out with some substantial solution.
  • Same here. Dust, dust, dust
  • I bought my red 920 in early February and haven't encountered this problem to this day. Malaysian unit, by the way.
  • Add me to the list. Dust here.
  • I had dust in my front camera and now the phone is in for repair with a prox sensor problem :-)
  • I have the same issue but thought it due to the earpiece leaking dust and the camera being so close to the ear piece hole. would love to have it fixed.
  • As far as the proximity sensor issue goes, I found that it might well be some electrical problem. Probably some loose connection. When I make a call the screen surely goes black, but when you squeeze the top left part of the phone the screen comes back on. It goes back to back when you release your fingers. To me this is clear evidence of a poor electrical connection.
  • It's True?Ι will cancel my order, Because tomorrow will come from UK. :(
  • Carry your phone in your jeans pocket? Does it sit in there with the earpiece at the bottom of your pocket? ...the place where all that fine pocket lint collects itself. Bingo! Now you know WHY it happens. At least that's my theory.
  • I had the 920 for a week before the ffc filled up with dust.
  • So far no issue here.. Touch wood
  • Same dustprob for me. I'm waiting for a respons. i sent it in for repair last week. i hope to hear something soon!
  • I have the same problem but proximity sensor is working fine as of now
  • Dust and proximity sensor problems here too. I sent the phone to  nokia... two times and nothing, the problem still here. Nokia needs to find a solution.
  • having a dusty front facing camera too :(
  • Well I had my Nokia Lumia 920 replaced 2 times already, I sent an email to Mr. Elop and he forwarded my complain to customer care, that was almost 3 months ago. I have to recognize that in my case they have taken care of me reason why I stick to Nokia. The only thing is that in any of the cases when dust got into the FFC the proximity sensor was failing, so I can't say is related.
  • AT&T actually replaced my 920 due to the proximity sensor issue. Impossible to call many places and "press 1 to continue.." when you can't see the screen.
  • I have the same problem...
  • Agreed.. Phone design is defective.. I love my phone but it sucks to not be able to mute my phone sometimes because of proximity sensor nonsense. Little canned air does the trick but still.
  • Dust in the camera lense and prox sensor bugs out sometimes.
  • I was aware that this was the culprit from the start. Between the glass and the plastic bezel there's a clear gap right above the lens. It probably wouldn't have been as much of a problem if the bezel fit more tightly. But even on my other Lumia, where the glass is tighter to the bezel at the top, dust has found its way in there.
    Short of disassembling the phone, I don't see any way to clean it out. Although, once you're in there I'm guessing you could slip in a piece of rubber or foam to close off the opening. I definitely wouldn't spray compressed air inside. Many of the components inside this phone are sandwiched in place, not actually held with screws. So the pressure can cause stuff to shift and contacts to break.
    Better to just deal with it until a fix comes along. Although, I think it's highly unlikely that will happen. So better still is to get a case.
  • yea i have samo problem. which is fix by dust off spray
  • Have blown out dust on the FFC twice and experienced the proximity sensor problem once which corrected after blowing out the dust with compressed air.
  • Same problem here: dust under the ffc and proximity sensor is faulty. I just recognized that if the screen is black during call holding the phone under a lamp brings back the screen for me. So is the proximity sensor somehow combined with the ffc as an light sensor? Anyone else can reproduce this?
  • Having the proximity sensor problem. I blow air on it almost every week... getting annoying but at least I have a temporary solution 
  • Dear Mr Elop ... your 920 defect is pushing me to look at Galaxy 4. I was ready to buy a 920. The dust report stopped me cold.
  • Of course this is dust related. I bought my Lumia 920 in Desember. I've had the proxy sensor stop working on me twice.
    Luckily for me, my workplace has air compressor. I put it over the mic-in, and blew gently. The front glass actually started to bulge and I saw dust shoot out of the phone. After that, no more problems with the proxy sensor. I've done this twice and it worked both times.
    If this isnt something covered by warranty this will absolutely be my last Nokia phone. I've already sendt my L920 in twice now for random reboots when im only using 4G. So this will most likely be my last Nokia either way, but this seals the deal. 
  • Yep, dust on front camera lens. And if i go to service it will took 5 days to up to 3 weeks before i get phone back. think i will clean it by myself.
  • I also have in my dust, but what causes the problem of the sensor when the phone has no access anywhere, try cleaning the sensor, connect the screen again soon.
  • Same here, dust in front of the front-camera and software issues with the proximity sensor...
    Hope it can be fixed with firmware update...
  • same problem: can see dust on front camera. and proximity sensor problems. Solution? my next phone will br Sumsung
  • Yes. Blank screen in calls.
    No screen protector, wiped sensor area clean, blew compressed air.
    Blank screen unless held in bright light.
    Especially useless at night with little to no light. Kiss the keypad away and hope the other end hangs up.
  • Yep. Between the ones I had replaced, my friends and my roommate's....*all* of them had/have dust under the screen at the front facing camera. They need to get their shiz together as this was the first leap from HTC I have taken and between this and the device (although replaced a few times) still locking up during standby once in a blue moon (which prevents me from using it as my alarm).....if it's not sorted out, my next phone will be an HTC again because none of my HTC windows phones (the older Windows Media Phones not being considered) locked up. One surround had a reboot issue but it at least it never froze preventing it from waking me up for work. 
    I messed since up then a couple of times but I stopped using it as an alarm the second the "working" one eventually locked up. I missed my wakeup by an hour causing me to lose out on a $450 shift and me to have to explain myself. Thankfully it didn't sour my reputation outside that week (at least to my knowledge). 
  • Finally found the problem, and in the discussion area... That are not useful, CEO, like adding a water charcoal.
  • Same problem.  I have to blow my phone out with compressed air every couple of weeks to get the proximity sensor working again.  Great phone.  Fatal flaw.
  • Yes I am seeing the same issue and it is driving mad. This is a defect by Nokia that should get fixed as the front camera is useless.
  • Looks like at&t is wise to this issue. I got a warranty replacement for dust under ffc 6weeks ago and within 2 hours had dust on replacement. Waited for it to get worse and called at&t. Reply was they can't replace unless Nokia admits this is an issue. Chat with warranty next day resulted in "your phone is no longer under warranty" wtf!!?!
  • Confirmed phone is still under warranty, just not for dust under ffc issue. I hope fix is on way.
  • Update: at&t is replacing my dusted phone but after much hassle on my part. They (at&t) called Nokia and Nokia said it IS eligible for warranty but wouldn't say wether it was a KNOWN issue.
  • Replacement  #4 has dust after just a few days.  Don't tell me this isn't widespread!
  • Still no word from Nokia on such a serious issue with Proximity sensor?  Please provide an udpate. Thanks.
  • recycle this......"smartphone" nokia Please.
  • Installed the new Firmware-Update from Navifirm and the proximitysensor problem is solved for me. Good luck to all others having problems...
  • Same issue here. Switched from an iPhone 3GS when 920 came out as it seemed to be the best phone out there at the time. The alternative I considered was Samsung Galaxy Note II. I was debating but, when 920 was announced at $99 on contract versus $299 for the Note 2, the choice was easy.
    However, now, because of this proximity sensor problem, I am inclined to think I made the wrong call. While 920 is still nice for all the smart features it has, as a phone -it sucks big time. I have to say I didn't expect this from Nokia as they've been around making phones for a lot longer than Apple or Samsung. As a phone, it simply fails. If this issue doesn't get sorted out/fixed, I am considering buying the Note 3 when it comes out (at full price if I need to) and probably never buy a Nokia again.
    Nokia, are you listening?
  • my nokia lumia 920
    i have the same proximity sensor problems too
    i originally thought it was my fault as i am a tradie and i am around dust all the time
    the front facing camera is full of dust
    but the phoning and black screen is very annoying i waited a long time for this phone my son got the 820 and has no issues
    blowing soft reset all a pain in the butt when you spend hard earned cash on a device as this you would expect better
    with all the competition out there i just dont get the ostrich mentality stop sticking your head in a hole and do something about this problem
  • I have this issue too...there's so much dust that it makes the front facing camera useless.  I wonder if ATT will allow me replace it with an 820?
  • Has there been any follow-up from Elop?
  • Surprised that no comment has been posted saying the 1308 firmware update should fix the problem.
    As I'm still waiting for it (T-Mobile in Germany) can anybody who already got it tell whether it actually does help??
    The black screen issue is driving me nuts...
  • firmware isn't going to fix a dust issue.
  • Well, all information on that release include that it should fix the proximity sensor issue during calls. It won't keep the dust away, but apparently adjusts the sensitivity of the sensor so the screen won't turn off when not held to the head during a call. So again, any feedback on that?
  • My 920 has dust.
  • Same problem here, this problem have started since last week... I don´t know how can I fix it. ..
    Greetings from Brazil :o
  • Same problem here. My 920 front facing camera looks like a snowglobe. I called Nokia and spoke to some undecipherable support tech in Bangladesh or wherever. First she wanted me to do a system restore on my phone, LOL. I told her nope. Then she told me to call a company named Palco and hopped off the phone with me lickety-split. I called "Palco" and got a voicemail saying their hours were 9-3p Central Time (must be nice). In short, forget this. I'm not sending my phone into some unknown Nokia partner for 2 weeks while they troublshoot bad design. Between this, the proximity sensor getting dusty and not working, and those God-awful Nokia apps I'm done with Lumia phones.
  • I still have dust in mine. I never use my video calling features because of it. My image is so grainy/blurry it's just not worth it. I've called AT&T about it before but all they could tell me is that it is a known case, and that I can swap it under warranty, but it's a swap...not a fix, and I'm just going to have to do it again someday. Not a lot of positivity there. So I never sent it in. I've considered popping it open...but don't have the balls yet as I love the phone too much to damage it. I just hope that the 930 won't have this issue....bad enough I have to deal with the headphone jack no working. The first one went out one day when I plugged in a pair of earphones at home. I swapped it out under warranty and about 6 months later, I plugged it into a speaker at work and pop!.....jack won't work anymore. It's like the cable had static on it or something and took out the jack. I gave up and don't listen to music using the phone anymore unless it's via bluetooth. Really pisses me off :( Now that 8.1 has a built in video option for calls...I really wish more than ever that it didn't have a dust issue. Even though I have never enjoyed a phone as much as this Nokia, this may be enough to get me to switch to the HTC when my contract is up in November....
  • Understand this is an old post but im having probs with dust/condensation inside ffc making my pics have a foggy hazr to them. Gonna try and fix myself..we'll see how it works out.
