Apple will notify the warning message on iPhone 11 and iPhone 11 Pro running on the iOS 13.1 if it detects that these devices are not using the Apple Genuine Display. The warning is displayed on the lock screen and appears for 4 days. After that warning will appear on the Settings App for 15 days before it is moved to Settings >>General >> About section. Anyway, the warning appearing on the lock screen or Settings doesnot affect the performance but reduces the true tone that had been happening since 2016.
As iFixit points out, the warning message appears when Apple Genuine Display is switch to another one. The way to avoid this situation is getting the Display installed from the certified Apple technician who uses the verified software tools to repair the display.
Apple seems to add this new warning message to the updated iOS 13.1, as it is not present in the previous version of iOS 13 and iOS 13.1.
We’ve tested this with genuine parts on iPhone 11 models. The warnings were not present in iOS 13.0 or the beta for iOS 13.1, but they show up when you change out screens with the final version of 13.1 installed. We used screens from the same models of iPhone 11, just days old, but without the software verification tools available to Apple-certified technicians, our units had warnings about a “genuine Apple display.”
We even swapped the Face ID hardware from an iPhone’s original display to the replacement, hoping that would convince the phone that it still had its original screen, but the screen warning remained. It seems that Apple cryptographically pairs each screen to the iPhone it ships on.
As it seems that Apple had a great move for the positive outcome, as all the consumers are aware of the duplicated display that isn’t the Genuine Apple Display.
Are you excited to get this update on your device?
