So I was cleaning my iPhone 5 (wiping it down, etc.) and noticed dust on my camera lens. When I tried to clean it I realize its actually under the lens. Now pictures don't seem to be too affected, maybe a bit more noise. But has anybody else had this problem? Would Apple replace the phone? This would be the 4th iPhone 5 for me due to a plethora of defects if so. I'll take a picture when I'm home and have access to another camera.
