Earpiece Replacement and Face ID Functionality
I’ve been asked to replace the front earpiece for an iPhone 11 Pro Max. Will Face ID still work after replacing this part? I’m a bit uncertain about this from the repair guide: “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”.

It seems that the flood illuminator is included in the earpiece that needs to be replaced. Anyone have any experience with this repair?
