Last week, 9to5Mac reported that Face ID stops working if you replace the iPhone 13 screen with a third-party repair. Now a new video shows that it’s possible to replace the screen and get facial recognition to work, but it’s not easy.
When we covered the original Phone repair guru video, he said that even when you replaced your iPhone 13’s screen with another original screen, a message appeared that said “Could not verify that this iPhone has a real Apple screen”.
He then suggested that there are workarounds like other parts of the new screen, but most repair shops wouldn’t because it’s “too fancy.”
In this spirit, I correct, a third-party repair shop in the UK, has proven that it is possible to replace the iPhone 13 screen without losing Face ID, but, indeed, it is a very sophisticated process.
In a blog post, I correct explains why Face ID is disabled on the iPhone 13 when replacing the screen and also gives the context since Apple introduced this technology with the iPhone X:
“According to our research, the iPhone communicates with the screen via an electronic chip integrated into the screen. This screen chip is an integrated circuit (an assembly of electronic components made as a single unit) responsible for translating your analog touch (your finger pressing your screen creating an analog signal) into a digital signal (for your iPhone understand that your iPhone is a mini computer and does not understand analog signals)
(…) The iPhone 13’s display IC now not only acts as an ADC, activates True Tone, carries a ROM for the non-genuine message, but now also communicates with Face ID. We believe this communication with Face ID is a bug in iOS15. But it shows us how much more complex the display IC will be in the future. We expect that the next generations of iPhones will contain 2 biometrics in Face ID and in the Touch ID screen. We expect that replacing a screen in the future will turn off onscreen Touch ID.“
While our last take on Apple’s action concerned the Right to Repair law controversy, I correct has a different take on why the Cupertino company is so picky about third-party repair shops:
“In my opinion, and something I cannot comment on for the whole industry, is that this is not a fight against third party repair, it is the fight of Apple with China. As consumers and repairers, we are right in the middle. Apple designs great technology on the outside and inside, they have it produced in China, which then takes the technology apart and manufactures alternative parts. Apple is using its own genius against the Chinese by blocking spare parts. Unfortunately, this also means that they also block the use of their own coins. This genius of the big tech makers can be seen as a control through the serialization of parts, as discussed today.
This decision to turn off Face ID was originally viewed as a checkmate decision by Apple, but today I’m happy to report that it’s just a check.“
You can watch his seven minute video showing the same as Phone repair guru then how to replace the screen while keeping Face ID on iPhone 13:
