Dear all, I noticed a circular notch around the rear microphone hole. It's normal ? Could you post photos of your rear microphone? Thank you

I don't have the Air 3, but I had the Mini 5 as does a relative. They had what sounds like the same problem having kept it in the case since new (I got Cellular so had removed it periodically to change sim card and give it a clean at the same time.) I noticed the issue when changing their screen protector and unfortunately not all of the build up would come off.
