Apple iPhone XS Max Ear Speaker with Sensor Flex Cable Ribbon Replacement
Follow the steps in this guide to remove or transfer the earpiece speaker and front sensor assembly in your iPhone XS Max. This assembly includes the earpiece speaker, 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 can restore Face ID function.
