Replace a malfunctioning earpiece speaker and sensor assembly in your iPhone XR and fix problems with phone call audio. This speaker is used to listen while the phone is held to your ear. The assembly includes the flood illuminator and proximity sensor.
Note: The Earpiece and Front Sensor Assembly includes the flood illuminator, which is part of the Face ID security feature. The illuminator and sensor array are paired to the logic board in an iPhone XR. Replacing this assembly and the components that are paired to the logic board will not restore Face ID functions.
