Face ID will no longer work on iPhone 13 if you replace the screen without Apple’s help. How can you get around this problem

Also confirmed by iFixit specialists, the “trap” strained by Apple in the design of iPhone 13 phones is an effective means of discouraging screen replacement interventions outside the repair centers authorized by the American company.

Given that Apple does not offer alternatives to Face ID authentication (eg fingerprint reading), losing this feature is a difficult compromise to “digest” for fans who have already paid substantial amounts on the new iPhone.

Considered one of the fiercest opponents of the “right to repair” movement, Apple has over time raised numerous obstacles to prevent the repair of devices outside its own service centers: screws that can only be unscrewed with screwdrivers owned by Apple technicians, “coded” components so that they cannot be replaced by other compatible parts, housings designed so that they cannot be disassembled without the aid of special tools, clauses providing for the cancellation of the guarantee, etc.

Even though many of the demands for the “right to repair” movement have been transposed into EU law, forcing Apple to abandon more aggressive practices such as coding parts to not work at all, the company has still found “loopholes” in legislation to sabotage repairs. unofficial, disabling certain phone features for security reasons.

Called “serialization security,” Apple’s strategy involves disabling certain features, or even the entire device, if an unauthorized component is detected in its configuration.


The process involves using specialized software to record the serial code, unique to each iPhone component, directly on Apple’s servers. Designed to be impossible to fool, the system does not allow the reprogramming of the serial codes assigned to the components, and to access the Apple servers you need the Apple Services Toolkit 2 software and the credentials of an authorized Apple repairer.

Described as “a black day for both amateur and professional repairers”, Apple’s move to “connect” the Touch ID sensor to the OLED screen module via software, even if they can be physically separated from each other, can only be reversed with great difficulty. According to iFixit, repairers will need a microscope and new expensive equipment to try to “transplant” the microcontroller that stores the identity of the old screen to the replacement.

Previously, until the iPhone 12 generation, only the physical replacement of the Touch ID sensor triggered its de-authorization, the screen replacement having few unwanted side effects.
