This is just a minor issue actually. I just noticed that dust particles are collecting under the surface of my iPhone camera lens. So far, it hasn't affected any of the photos I've taken... yet. Are there any measures that should be taken?
If dust has penetrated the seal between the camera and the glass lens on the case, the only way to clean it would be to open the case up and remove the dust. This can be done by the Apple store or one of the many third party service kiosks/stores in every neighborhood. Are you sure the dust has gotten under the glass? While dust does get inside the phone from storage in your pocket/bag/desk etc., Its a very rare occurence that the dust would make it all the way under the glass.. The good news is that it is serviceable.
Thank for your advices everyone! Right, I'm sure that the dusts I mentioned are under the lens. I will take it to the Apple Store if it started affecting my pictures. Any guess on the costs? For the lens detachment I mean.
