Mine is also with this problem, around the camera. Really disapointing. I've got a white Lumia, btw. Really seems an issue with the gloss finish. :crying:
I'm on my second white 920, this time I've been keeping an Otterbox Defender case on it for work and day to day use.. and when I want to show it off, I simply remove the case and reveal the sexy, flawless, and scratch free Stormtrooper white Nokia Lumia 920!
Like others have mentioned it is probably the gloss coating. It will never wear off naturally like that so i'm pretty sure it is a result of dropping or scratching somehow.
I think it is normal to have dents and scratches on your phone w/o a case, which is what we all were prepared for when we decided to use the 920 naked
The 920 is worth being used naked. I have slight dents and scratches but they are hardly noticeable thanks to the gloss finish.
It's one thing to keep your phone in a case, to keep in mint condition for trade-ins later which I sort of agree on but you really don't get full advantage of using the sexy 920 in final form.
I would rather sacrifice the mint condition and use the 920 to it's full potential everyday till it dies on me.
