I have Whitedome screen protector and camera protector on mine. I don't use the camera often but I haven't noticed any issues with having the protector on. With my work, I feel my camera would get scratched up easily so I feel better having it on and will take the minimal loss that may come with it.
Is there any big need or issue with getting a protector for cameras?, if so what would be a good choice that wouldn't cause flare or interference with flash?
