The logo and the iPhone word on the back of my iPhone looks like this:
Both seem to have this 'ring' around. I'm using a SwitchEasy screen protector at the back but the ring has been there since before I put it on. Same goes with my Aunt's black iPhone 5 but my matching iPad Mini doesn't have this problem.
So, what is this problem called and what caused it? And how do I get that ring out? I checked the photos of the iPhone online and they don't have this.
