Several users of iPhone 13 have reported a problem that is, to say the least, random: The device's screen turns pink, making it impossible to use the phone without restarting it.
One of the first cases to be reported dates back to October, in the discussion forums Apple. Although, in this case, the device in question was replaced, other users began to report the same problem in the following weeks and months. While some customers managed to replace the iPhone 13others were not so lucky, since the Apple said it was just a bug from software. Reading the reports, it is not possible to find a pattern that explains why this happens, although it seems to be restricted to the line iPhone 13. According to one user, in December: "I had the same problem when taking a photo and the screen not only froze, it turned pink and then restarted. I called AppleThey made the diagnosis and said there was nothing wrong."
Also on the social network RedditSome users ended up reporting the same situation: "This happened to me the other day while I was in the car. It was preceded by my GPS was giving me completely wrong directions, away from my destination, until I turned it off and on again. During this time the screen turned pink".
Among all these complaints, the blog My Drivers discovered that Apple made a statement on the Chinese social network WeiboThis is precisely because the vast majority of cases appear to have been in China. According to the US company: "We have not detected any relevant problems with the hardware of the devices, since this situation [pink screen] is caused when the system is locked."
According to the publication, the Apple advises users to do backup of your data, and install the most recent update available, in order to rule out incompatibility between a version of the application and the version of the iOS. Since then, the iOS 15.3 RC does not mention fixing the pink screen bug, which also causes confusion among users, since some of these reports first appeared when the iPhone 13 was originally released.
