Stain/discoloration on the back of iPhone 7 plus
I bought this iPhone a month ago and I immediately put it in a case. I took the phone out yesterday and I noticed the back is stained around the camera and above the Apple logo. The color looks brighter on those areas and it's really bugging me. I tried cleaning it with a cloth and water but that didn't do anything. Is there any way to fix this? Thanks.
iPhone 7 Plus, iOS 10.2
