By interchangeing two iPhone 13 Pro screens, the Youtubeur Phone Repair Guru realized that Face ID no longer worked on his devices.The function is deactivated if the screens are exchanged, but reappears once the slab is put back on its original device.For the moment, it is difficult to know if it is Apple's desire to limit repair, poor manipulation of the videographer - Ifixit had noted from the iPhone X that Face ID was very sensitive to screen replacement - or something else.
Blocking Face ID for third-party repairers would be a rather daring approach on the part of Cupertino, because none of the components of facial recognition technology is apparently linked to the screen, these being all included in the phone box.The apple could not use the security argument to justify this blockage as it could have done with Touch ID (some components are well linked to the slab).
One hypothesis is that the screens replacement process on iPhone 13 includes an additional validation step, only step available for Apple Store and approved approved repairers.Another possibility, an iOS bug, as was the case in the past during replacements of the Touch ID button by non -approved repairers.
In recent years, Apple has implemented several measures concerning the unofficial components installed by third -party repairers.From the iPhone 11, a message in the settings indicates if the installed screen is not official.IPhone 12 can prevent the user if the photo block is not original.In the event of a change of battery excluding Apple circuit, iOS invites you to change battery.
Apple justifies these steps by explaining that it has a large number of approved repairers, which is not necessarily true in all countries.She also defends herself by arguing that the installation of unofficial parts can be dangerous for the user and damage his device.Apple has not currently responded to media requests on this inoperative ID ID case on iPhone 13.
Update on September 28: Ifixit confirmed that Face ID no longer works in the event of a screen change by a third party.
