How to remove stain on the back camera iPhone 4s?
I have this stain when I use my iPhone 4s' back camera. It's especially noticeable on white surfaces and is super annoying.
I don't think I had it when I bought the phone.
Anyone knows how to get rid of it?

NOTE: You will need a PENTALOBE screwdriver which is an Apple only screwdriver that you can order from ifixit or eBay.
