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

Dusted Lumia 920

The Windows Phone Primal Forums are a place of immense knowledge, resources and camaraderie. There is no better place on the web to hang out if you lot'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 end-facing camera. Hither's his story and what he found while trying to gear up the situation.

His outset Lumia 920 was replaced because of the grit in the camera, which could easily be chalked up to problems with beingness an early production right? Not quite, equally his replacement unit started having the same effect.

Communication with Nokia to gear up the second handset was fruitless. He started with the support team on Twitter which wanted him to follow the normal repair procedure – the ane that leaves yous phoneless for nigh 2 weeks, which isn't satisfactory in the least. Mostly considering other members in the forums have reported all they do is take a tin can of air and blow the grit out for you. He then reached out to Matt Rothschild who passed him to the Nokia Intendance Team, where Eric learned that the issue was not covered under warranty. He and so reached out to Stephen Elop (some members accept had success in the past) and did non get a response there.

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

At the top of the telephone, there is a seam near 1/2mm tall that runs the width of the device. Information technology is located where the glass and polycarbonate housing meet. It'due south all sealed except for one part, where the camera sits. The images below illustrate what Eric found.

Lumia 920 Dust Gap

In this epitome he illustrates where at that place is a cutout to hold a rubber gasket. However, the adhesive holding the rubber gasket is only sealed on the sides and lesser – 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 grit 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 take access to any of the options on screen. The image beneath shows the gap to a higher place the front-facing photographic camera a lot improve.

That all being said, fifty-fifty though they are correct side by side to each other - there is no way for dust to enter the proximity sensor. I couldn't really believe it either. But Eric institute that the proximity sensor and front-facing camera are separated by a wall and sealed upwardly tight, no way for dust from the camera area to work its way to the proximity sensor. So what'due south causing proximity sensor problems for users? Your guess is as good as ours at this betoken.

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

Update:Afterward publishing this to the front folio of Windows Phone Central, Eric was contacted by Mr. Elop. The e-mail stated that his team will wait into the situation. Eric will update all of us if anything noteworthy takes identify. Until and so.

Does anyone else take dust under their front-facing camera on their Lumia 920? Any other theories as to what causes bug with the proximity sensor? All the same recollect its dust related? Sound off below.
