According tomedia reports, a number of iPhone 11 series users recently found that their phones unlocked after the emergence of a “green screen” situation. This is reflected in the fact that after unlocking the phone, there will be a few seconds of green screen problems, and then will recover on their own, but the next unlock will still appear, even after the restart still does not improve.
Some users believe that it may be dark mode enabled, resulting in this situation, and some users said that it may be caused by the screen brightness is too low.
But these explanations seem untenable, as many users say their phones are completely normal and will still turn green. As things stand, the iPhone 11 Pro and Pro Max seem to be more affected.
The issue was originally raised by a small number of iOS 13.4 users, and became more serious with the update of iOS 13.5 and iOS 13.5.1.
According to domestic media reports, Apple China customer service said, did receive similar problem feedback, screen green to the after-sales point to test, if it is a hardware problem, you can go to the warranty procedure.
Since screens are isolated, there are no official documents to answer this question.
