How do you stop dirt getting in the camera lense space? It's so easy for dust/dirt, (fingerprints trying to wipe it when I see dust)to get in there when you put the phone down facing upwards. I have OCD, in terms of it being clean etc! On my iPhone 5, I left the plastic back casing on as it was two separate sections but the iPhone 6 plus came with one unibody plastic film. (Basically the wrapping it came in) I've removed it and put a screen protector on the front, and a case but the camera lens part is vacant.
