Replacement earpiece speaker with proximity sensor flex cable for iPhone XS. Attention: The Face ID function is not reversible. The sensor detects when your face is close and turns off the display, while the earpiece speaker controls the sound during a call. If both of these parts are broken, making calls may be difficult. Repair your iPhone XS so you can make normal calls. Professional installation is recommended. All parts are tested before shipping. Compatible with A1920, A1997, A2098, A2097, A2100.
