Starting with iOS 18, Apple no longer requires the original serial number from your old screen to activate the True Tone function. However, if the new screen lacks a serial number, the auto-brightness function will be disabled.

PicoRepair ensures that the new screen retains auto-brightness by reprogramming it with the original serial number. We recommend asking your repair shop to copy the serial number during the replacement process, as retrieving it later can be challenging.
