How to Fix iPhone X Face ID Not Working

 If you own an iPhone, you've probably experienced Face ID not working at least once, getting a message to move iPhone a Little Lower/Higher. Today, phonefix will share how to fix iPhone X Face ID not working.

Software problem

Step 1 Check for updates

If there is a new version available, downloading and installing it should solve all problems. If you have important data on your iPhone, make sure to back it up using iCloud or a computer.

Step 2 Restart your iPhone

Restarting the phone can also fix the "Move iPhone a Little Lower/Higher" message. Please follow the steps below to restart.

1. Press and hold the iPhone volume keys and the side button, and wait for the power off slider.

2. Drag the slider and wait for iPhone to shut down.

3. Before you start your phone, wait a few seconds, then press and hold the side button to turn it on.

4. After the iPhone restarts, try using Face ID.



Step 3 Factory reset iPhone

If none of these solutions work, the next step should be a factory reset, which may or may not fix the Face ID bug, but at this point you have no choice. Before you factory reset your iPhone, make sure to back it up using iCloud or a computer.


If none of the above methods resolve the message issue, your situation may be related to a hardware failure. The next step is to troubleshoot face recognition.

Hardware problem

Step 1.Test Flood Illuminators

Let's start with the flood illuminator. There are two important parts of Face ID whose behavior relies on flood illuminator support. As part of our day-to-day repair work, we can confirm that the floodlights are working properly by testing the proximity sensor and ambient light sensor. Let's make a call to confirm that the proximity sensor is working. During a call, cover the top of the screen with one hand. We can see that the screen goes black immediately. From this, it is judged that the proximity sensor is working normally.

Next, test the iPhone X Ambient Light Sensor Flex

Turn the screen brightness down to minimum and place the phone in bright light. As the screen gets brighter, we can confirm that the ambient light sensor is working as well. From this, it can be judged that the failure of Face ID is not caused by the floodlight.

Step 2.Test the iPhone X front camera assembly

Let's move on to the next step where facial recognition doesn't work - testing the front camera part.

Open the camera app and swipe to portrait mode. The background is not blurred, which is not normal.

Step 3.Observation point projector

In portrait mode, there is no flashing red light from the dot projector. But Dot Projector should flash red light in normal state. We can now confirm that the Dot Projector is down. This is the glitch that caused the Face ID setup to fail. We can fix the glitch with the JC Dot Flex Cable, which is used to fix iPhone Face ID low/high issues.

If it is a software problem or a temporary system failure, it can usually be solved after restarting. In addition, the infrared camera, flood illuminator and dot matrix projector are paired with the mobile phone. Damage to any of these can cause Face ID to fail, and such a problem is irreparable.

 In today's fast-paced life, the frequency of use of devices such as mobile phones, tablets and smart watches is increasing. Many people often encounter the problem of insufficient power on their devices, especially when they need to travel or do important work. Slow charging of devices may be caused by insufficient power of the charger, faulty charging interface or the use of mismatched charging cables. These problems not only affect the efficiency of device use, but also increase the anxiety of users. There are two main ways to solve this problem: Choose a more powerful charger: A high-power charger can provide a faster charging experience and save waiting time. Make sure to use compatible charging cables and interfaces: Using mismatched charging devices may result in slower charging speeds. Using charging methods designed for your device can significantly improve charging efficiency. Considering these issues, the MECHANIC V-Power series of fast chargers provides users with solu...
