Follow the steps in this guide to remove or transfer the earpiece speaker and front sensor assembly in your iPhone 12. This assembly is affixed to the back of the display and also includes a microphone, ambient light sensor, flood illuminator, and proximity sensor.
This assembly 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.
The flood illuminator forms part of the biometric Face ID security feature, and Face ID functions will fail if the original component is damaged or incorrectly installed. Replacing it with a new part will also cause Face ID to fail, 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.
What you need

Power off your iPhone before beginning disassembly.

Remove the two 6.75 mm long pentalobe P2 screws at the bottom edge of the iPhone.

-
-
-
Push the blue handle away from the hinge to engage opening mode.

The title of this Guide is "iPhone 12 Earpiece Speaker and Front Sensor Assembly Replacement". The text and photos ONLY SHOW DISASSEMBLY AND THERE IS NO GUIDE ON REASSEMBLY...ESPECIALLY THE DETAIL OF HOW THE PART IS REATTACHED TO THE SCREEN! My experience of this guide is that it is a 50% proposition and is not helpful.

Finally someone said it, any one that’s doing something like this as a beginner is kinda screwed with reassembly the whole in reverse doesn’t work with visual people
