So unless your iPhone 13 is taken to an Apple store, a repair shop in Apple's Independent Repair Providers network, or a shop with more advanced tools, you're risking that functionality. Hillary Kladke / Getty Images The culprit is a small microcontroller chip paired with the phone's screen, which has to be synced in order to work properly. Apple has yet to provide independent repair shops with a way to replace or pair new screens and microcontrollers, making the process practically untenable for smaller businesses. Some shops can move the chip from the old screen to the replacement, but it's a much more labor-intensive process that requires micro-soldering. martin-dm / Getty Images According to iFixit, Apple support has said the issue would be addressed in a future iOS update. iFixit theorizes that Apple could update the software to issue a warning that FaceID can't be verified rather than lock it out entirely. This is just speculation, however, and relies on Apple deciding to make such a change. Currently, the only notable difference between iOS 15 and iOS 15.1 has been the addition of an error message stating that FaceID can't be activated. Was this page helpful? Thanks for letting us know!
