many users have noticed severe scratches on the back of the display units of the iphone 17 series at apple stores. this was attributed to a defect in the material that is prone to scratches, but apple later issued a statement denying this claim. apple stated that the cause of the scratches was a problem with the bracket material used in the display units. after investigation, it was found that the metal material on the edge of the bracket had adhered to the back of the iphone 17 series due to repeated lamination of the display units. this material can actually be removed.
to completely address this issue, apple recently replaced the brackets at the renovated apple store in ginza, tokyo. this involved installing a silicone protective ring on the original brackets. this protective ring is made of soft silicone and prevents serious metal "scratches" when the iphone 17 series comes into contact with it.
of course, the scratches already present on the display units also need to be cleaned. apple has instructed employees at its stores to regularly clean the display units using a mixture of salt and regular cleaning solution. this method can effectively remove scratches on the back.
a test was conducted on an iphone 17 pro as a sample on the website, and it was found that cleaning with a mixture of water and sea salt was very effective. of course, these stains are relatively minor and should be easily removable with other solvents.
display units on store shelves are often handled and installed frequently, so they are prone to wear and damage. however, regular cleaning is essential, as users may misunderstand that there are problems with the materials of the iphone 17 if they are not cleaned regularly.
