The latest iPhone 13 Series completely disable the Face ID sensor if it’s repaired by someone unauthorized by Apple, and makes it completely useless.
Apple is known to disable Face ID unlock upon a screen repair if it wasn’t carried out by Apple Authorized technicians or repair shops, but the latest iPhone 13 Series goes a step further. Suppose a third-party repair shop fixes the screen on any of the iPhone 13 Series. In that case, the Face ID sensor will stop working altogether, and it won’t let the user authorize payments, sign in to an account, unlock the device (with Face ID), send animojis, and more.
