Apple today released a new support document with more details on replacing parts of the iPhone with third-party repairs. More specifically, the article mentions that the new iPhone 11 and iPhone 11 Pro can identify non-genuine displays just as older models can recognize batteries that have been replaced.
According to the company, iPhone displays are designed, tested and manufactured in compliance with Apple quality standards that ensure proper functioning and responsiveness for all aspects such as brightness, color accuracy, True Tone, Night Shift and Haptic Touch. Apple says there may be some problems with uncertified displays, including degraded multi-touch performance, unintentional touches, incorrect color calibration, and even more drain.
Starting with iOS 13.1, iPhone 11 owners will see a warning when using an unreal display device. Users will be notified under these conditions and this alert will always be shown by the iPhone in Settings> General> About.
There is also the possibility to see an additional notification that says, “Apple has updated the device information for this iPhone.” This means that Apple will keep records of any eligible iPhone with non-genuine displays for additional services, for example, making repair analysis easier. These notifications will not affect the use of the iPhone at least for now, except, of course, for the quality of the display.
Apple recommends replacing iPhone displays in an Apple Store, an Apple Authorized Service Provider (AASP) or even with Independent and Certified Repair Providers to avoid such a problem.
