Iphone 12 Pro Max camera lens
The lens - or whatever glass is the outside layer - on two of the three back cameras on my iphone 12 pro max is damaged. Can this top-most glass layer be replaced by itself? If not, if this is the only issue needing repair, is the repair replacing the back glass or the camera lens assembly? I presumed the back glass was all one piece and would need to be replaced, but an Assurion (certified apple repair) shop said the camera is the replacement for this issue (based on a description over the phone), and then I see self-repair videos replacing just the glass over the camera lens itself.
