Before you begin
If you’re fixing a broken screen, and the back of your new display already includes a thin metal LCD shield plate, you should follow this shorter guide for an easier repair. But if that LCD shield plate is missing, keep reading—this guide will show you how to replace your screen and keep your old LCD shield plate. The combined earpiece speaker + sensor assembly affixed to the back of the display is paired to your individual iPhone at the factory, so you must transfer it from your old display to your new one during any screen replacement. It contains the flood illuminator, which is part of the biometric Face ID security feature. If it is damaged or replaced, Face ID won’t work, so take extra care not to damage any of these components during this procedure. If damaged, only Apple can restore Face ID function. Note: True Tone functionality is disabled after a screen replacement, even when using an original Apple screen.
