Introdução
If your iPhone 12 Pro screen is cracked, not responding to touch, or not showing a picture when your phone is powered on, use this guide to restore your iPhone to working order with a new screen, a.k.a. display assembly.
The combined earpiece speaker + sensor assembly affixed to the back of the display is paired to your individual iPhone from the factory, so you must transfer it from your old display to your new one during any display replacement. It contains the flood illuminator, which is part of the biometric Face ID security feature. If it is damaged or replaced, Face ID will cease to function, so take extra care not to damage any of these components during this procedure. If damaged, only Apple or an Apple-authorized technician can restore Face ID function.
Note: On iOS 17.6 and earlier, True Tone functionality is disabled after a screen replacement, even when using an original Apple screen. On iOS 18 and newer, you can calibrate your new screen using Apple's Repair Assistant to restore True Tone functionality on genuine screens purchased from Apple.
