Apple ditched Touch ID in favor of Face ID when it launched the iPhone X back in 2017. Although the company reintroduced the fingerprint reader in more affordable iPhones, the convenience of Face ID likely means Apple has no intention of bringing back Touch. An identifier for any featured iPhone model launching in the future. Fortunately, that didn’t stop a moderator from doing the job himself and returning the feature to an older iPhone.

Although the A12 Bionic is several generations old, the SoC powers a family of iPhones that don’t support Touch ID. On Twitter, @lipilipsi revealed that it is still possible to bring a fingerprint reader to a device that appears to be either the iPhone XS or iPhone XS Max after looking at the virtual wallpaper. However, the modder did not use an in-screen fingerprint solution due to obvious space limitations.
Instead, it’s built a fingerprint reader into one of the iPhone’s side buttons, which is a clever approach and something Apple has done with the iPad mini 6 and iPad 10 as well. From its video, it appears as if @lipilipsi attached a component directly onto the A12 Bionic die, then used the ribbon cable to carefully attach the side button to recognize your fingerprint.

He meticulously soldered wires to go through the circular hole of the logic board to create as much space as possible, and at the end of the little video, he shows that the iPhone does indeed recognize your fingerprint. Although the text on the screen is another language, using Google Lens on our smartphone, the machine learning translation shows that iOS recognizes the presence of an additional sensor.
The software instructs the user to keep lifting and placing a finger on the sensor to register the first fingerprint, revealing that such a modification is possible, but it will definitely void your warranty on a newer iPhone. We are curious to see if this mode will be possible on the iPhone 13 or iPhone 14. We hope to see something like this from lipilipsi.
In case you forgot, this is the same guy who modified his eSIM-only iPhone 14 Pro Max to accommodate physical SIM cards, so his talent is immeasurable.
