Recently there have been a lot of reports that the iPhone X’s camera glass has been cracking. The users who experienced the problem have not dropped their phones and mostly the phone has been in a case. And they were using their phones in normal temperatures.
We believe that the glass may have some impurities that cause the glass to spontaneously crack. This exact issue plagued the Nexus 6P a few years ago – the problem was impurities in the glass caused by dust.
Surely Apple will crack down on the issue and get the matter resolved in no time!
