iPhone X - No Face ID after replacing the display, what to do?

Question

Hello.
Today I replaced the LCD in my iPhone
Strangely enough, face ID doesn`t work on the old LCD either, I doubt I could have done anything with face ID because I didn`t even touch it.
I only unplugged the LCD and the speaker module that is mounted on the LCD.
I am asking for help and some advice.
Thank you .

It will probably never work. It`s like touch ID and a fingerprint reader. You can replace it, but it won`t work with another one.

So why doesn`t it work even on the old LCD?

djjack · Answer

You probably need to program the new LCD with the input from the old LCD.

Dawkobor · Answer

But how to do it and who does it?

staś pytalski · Answer

There are devices for copying LCD content. A good service center has a device for such repairs.

There is also the issue of originality... Not every replacement can be programmed, but it is a matter of input from the old display

blahfff · Answer

It doesn`t work because you probably somehow damaged the tape or one of the elements responsible for FaceID. Unfortunately, these tapes are quite delicate. Programming the display only affects TruTone functions.

Dawkobor · Answer

Yes, the tape was slightly damaged, the service technician will try to solder it, but he doesn`t know what the paths look like and he is not sure about this operation. If it fails, it is possible to replace the entire Face ID with cameras so that Face ID works from another phone.?

blahfff · Answer

Unfortunately not. Only an authorized Apple service center can do this, including replacing the entire front. The situation is identical to that with TouchID.

Dawkobor · Answer

Is it possible to change the face ID itself?
The service technician suggested that I try to buy a new whole module and replace only the face ID tape, I marked it in the photo. He says that we can try this option because the cost of the entire face ID module used is PLN 70. Do you think it makes sense for fun? The cost of replacing the entire thing at an authorized service center is very high, he wanted to solder the flex tape for me, but he doesn`t have the appropriate equipment and he doesn`t know if it can be done at all, there would probably be 2-3 paths for soldering.

blahfff · Answer

Maybe someone will correct me, but as far as I know, the tape itself cannot be translated. You can transfer the elements responsible for FaceID to a new tape.

Dawkobor · Answer

What elements should be transferred from face ID to the new tape? Could you explain this more? Added after 6 [minutes]: Do you know someone who could solder it for me?

blahfff · Answer

Everything is described and shown in the first link, including the video. Unfortunately, I cannot advise anyone who could deal with this.

RafalB · Answer

Unfortunately, 3 elements are responsible for the correct operation of FaceID and none of them can be damaged. The elements on the front cam assembly are very mechanically sensitive and there is basically no way to repair them. If the tape is damaged, it can be repaired or replaced (IR camera or dot projector) must remain original.

JacekJbk · Answer

I only unplugged the LCD and the speaker module that is mounted on the LCD. This speaker module is one of the elements of Face ID. It is very easy to damage it, and that`s probably what happened.

Dawkobor · Answer

Hello. This tape has been replaced and now it says Face ID is unavailable. Now I don`t know what could be wrong...

VectaVecta · Answer

After replacing the tape, there was a problem with the TrueDepth camera. Does anyone have any ideas why? Before the tape was broken, everything worked.

bert_studionapraw · Answer

Hello, hello.

Describe the problem in more detail, every detail will be important for Face.ID.
You have already written today about the Face.ID problem in model 11, in fact it is quite a similar case. You can also use an analogy to that one.
