First, I am new to these forums and apologize if this question is in the wrong area or if it's already been discussed. I know there are forums about flaking from the matte black iPhone 7/7 Plus. I recently got an iPhone 7 Plus Matte Black from AT&T and have had it less than a week and the home button is discoloring. As seen in the photo attached. Has anyone else had this happen. For the record, it's not the angle that I'm looking at it because the discoloration is able to be seen from all angles.
