I used two cases on it: first for a couple of months a tech21 silicone case then a wallet case with a plastic phone part.Do you case your phone?
It has been there ever since I took the case off a couple of years ago.I was thinking it could be residue from inside of case if you just took it out and noticed it. I had that from a case on my 6 and it came off. If you took the case off a while ago and this just happened, then I don't know, sorry.
I actually don't know if there were scratches in those two spots!Looks like the finish may be coming off the phone. Many of the blemishes appear to originate from where the metal has been stamped/engraved for lettering/numbering as well as the Apple Logo. I wonder if the two rogue large blemishes started out as small scratches.
Is there anything I can do about it?Looks like the finish may be coming off the phone.
