4. Factory Reset iPhone

If simply resetting your iPhone settings doesn’t do the trick, then we’ll have to perform the most dreadful method available – Factory resetting the iPhone. Follow the steps below to ensure you properly perform this task.

This method will completely wipe your device of all data. So make sure to back up any important files before doing so. Hopefully, the “Face ID not working move iPhone lower” issue can disappear as well.

5. Test Flood Illuminator

This is a test specifically targeted to troubleshoot the Face ID functionality itself, due to hardware issues. If none of the above methods fix the “Face ID not working move iPhone lower” issue.

The Flood Illuminator can be tested by the Proximity Sensor and the Ambient Light Sensor. To test the proximity sensor, follow these steps:

Step 1: Go to your Contacts and make a phone call with someone.

Step 2: Make sure to cover the proximity sensor with your hand. The screen will turn black if the proximity sensor is working. If you don’t know where the proximity sensor is, you can cover the entire top screen part with your palm.

Step 3: To test the Ambient Light Sensor, set the screen brightness to the highest and hold the phone in a dark room; if the brightness reduces, the Ambient Light Sensor is working fine. You can also test it by reducing the screen brightness to the lowest and then holding the phone under bright light; if the sensor is working properly, the screen brightness will increase. If the Proximity Sensor and the Ambient Light Sensor are working fine, the “Face ID not working move iPhone lower” message has nothing to do with the Flood Illuminator.

The next half of testing the flood illuminator is to test the Ambient Light Sensor. To do this, set your iPhone’s screen brightness to the highest possible setting, and hold it up in a dark room. If the phone’s brightness starts to dwindle, then it means that the Ambient Light Sensor is working as it should.

Once you’ve determined that both sensors are working, then the “Face ID not working move iPhone lower” is not caused by the Flood Illuminator.

6. Check the Front Camera and Dot Projector

This is to test another potential hardware issue to see if your “Face ID not working move iPhone lower” is due to faulty components.

Open your phone’s camera app and switch to Portrait Mode. If the Dot Projector is working, your phone should start to emit a blinking red light. Otherwise, it’s not working properly.

The dreaded “Face ID not working move iPhone lower” issue might not be common for most people, but these methods should fix it should you be one of the unlucky people to still be encountering the error. If none of these fixes do it for you, then it’s best to head over to your nearest Apple store to get your device checked.
