Replacing of iPhone X display assembly usually won’t affect Face ID. However, we get complaints from our clients that Face ID on the phone failed after replacing of the display assembly. We have done some researches and our guess is that the problem might be caused by improper operation during the replacing process, which results in damage of flex cables or other components.

There are 8 components packed into the front of the phone. Infrared Camera; Flood Illuminator; Proximity Sensor; Ambient Light Sensor; Speaker; Microphone; Front Camera; Dot Projector;
The infrared camera, the dot projector and the front camera are located on the back glass assembly. The flood illuminator, the proximity sensor, the ambient light sensor, the speaker and the microphone are located on the display assembly. Please be careful when disassembling or repairing the phone. Damage of any of these components might cause Face ID failure.
