The iPhone face ID module is a complex system. Sometimes we don’t know why the face ID system cannot read our face. Here is a repair case about iPhone X face ID issue we would like to show you here. The face ID system keeps showing the message “move iPhone higher” but cannot read your face. We assume the dot projector may be damaged. We need to separate the dot projector and replace the flex after our test. Here we would specify the details.
1. Tear down the display and take down the front-facing camera module
1.1 Power off the iPhone, unbolt and remove the two pentalobe screws on the bottom

2.3 Install and connect the camera model back to the iPhone, turn on the iPhone to test and see if no “unable to activate Face ID on this iPhone” shows on the screen, that means dot projector data has been backup successfully
2.4 Power off the iPhone, disconnect and take off the camera module again

3.5 260℃ hot air gun blows on the flex and separate the disk from the dot projector flex
