iPhone X Face ID NOt working after change screen Rumor
 

People said the face ID will stop working as soon as you replace the screen. I havent have a chance to work on iPhone X yet but if anyone have work on iPhone X please confirm the info

Is Face ID stop working because changing screen on iPhone X?


Also on the 8/8 plus the light sensor will stop working too after change screen. I think it is a non sense rumor but still need confirm from a Pro

help me anyone same problem

Nope , it get stop if you mistakenly damage the cable of face id.

That is what I really think too. But many people who fixing phone report there is a problem with Face ID after changing screen

Also the same with the light sensor.

I will update when I have some customer come to my shop for 8/8 Plus

I currently dont service iPhone X

I confirm that the auto brightness broken after you change the screen. Even when you factory reset the phone. The auto brightness still not working

Got a phone that come today and it stop working as soon as the new screen was put on the phone.

So have you confirmed it?

Is it can be work with original touch screen?

The LCD and the sensor tight together.

Work like home button and motherboard ---> you change screen, the light sensor will not work.

Original LCD that come with the phone --> Working

The screen replacing would not affect face ID function at all according to our practical verification.
1. Resort to resetting face ID. Go to Settings > Face ID & Passcode > Reset Face ID
2. Disassemble the phone.
3. Then remove screws
4. Solder the Flood illuminator module to a new flex cable
5. Replace with a new flex cable. Remove the Flood illuminator module on the flex cable first. Prepare a new flex cable.
6. Re-solder the ambient light sensor module and earpiece speaker.
7. Re-assemble the phone and test. Press power button to power on. Go to Settings > Face ID & Passcode > Set up Face ID. Face ID can be set up successfully.

Have you ever confirmed the hardware issue? You can ask Apple Support to check whether the screen is installed without problem.

While for the software issues, you can try to update with iTunes or update iOS on iPhone X. It is also possible to fix potential system errors with an iOS system recovery Mac, using it to repair with No data loss. Or you can apply it to remove your Face ID without passcode and iTunes quickly.

It maybe is caused by camera flex cable damage during screen replace. Check this repair case - iPhone x face ID not working after change screen please, you will get something from it.

you need to buy new flex cable and replace 2 old sensor to new cable flex

Thank you guys! I have solved this problem

;)How can you solve your problem?
These are some method I find:
1. Fix Face ID Not Working by Cleaning TrueDepth Camera. The Face ID relies on the TrueDepth on the notch above the screen to identify your face, so iPhone face recognition fails if the camera is covered with dust or other things.
2. Managing ID Settings
Step 1. Open the Face ID & Passcode menu in Settings

Step 2. Toggle the Require Attention for Face ID switch and Attention Aware Features switch to disable them.
3. Update iOS
4. Add an Alternate Appearance
5. Use some iOS system repair tool such as TunesKit iOS System Recovery to fix without data loss. I think this must help you. Those software can fix other iOS system issues, too.

Why Face ID Can Be So Easily Damaged And Hardly Repaired?
