Is it possible replace Face ID parts?

You can only replace the front-facing camera. Here is the iPhone X Face ID tear down and analysis.

When the flood illuminator module flat cable get damage, Face ID wont work. You can fix that by replace the flood illuminator module flat cable but the original sensor has to move to new flat cable.

I have been reading some emails from the Chinese suppliers, that replacing the screen makes Face ID stop working. Even though the camera system is separate from the screen, Apple have made replacing the screen kill Face ID.

i would assume the face id is using the front facing camera, so unless the camera has some sort of feature like touch id i would say aslong as its an original apple camera then face id should still work

• There are 8 components packed into the front of the phone. Infrared Camera; Flood Illuminator; Proximity Sensor; Ambient Light Sensor; Speaker; Microphone; Front Camera; Dot Projector;
• The infrared camera, the dot projector and the front camera are located on the back glass assembly. The flood illuminator, the proximity sensor, the ambient light sensor, the speaker and the microphone are located on the display assembly. Please be careful when disassembling or repairing the phone. Damage of any of these components might cause Face ID failure.
• The three parts ( infrared camera, flood illuminator and dot projector) are paired to the phone. To keep Face ID working, the three parts should always be the genuine parts.
• Please be noted that there is a slot on the display assembly. When assembling the phone, the fold of the speaker flex cable should be placed correspondingly in the slot to prevent the cable from getting broken. Which will also result in the failure of Face ID.
• Warum Face ID nach einer Reparatur nicht funktioniert

I would not be too worried. Face ID is not on the screen when disassembled, so I think there will be less of a chance of damaging it.

From what I understand the dot projector is unique to each device.

I was testing the face id and it doesnt work It says "Face id not available" . I tested with two new phones . It doesnt seen interchangeable.

Note: i forgot to try doing a software restore. I will try and update when i get a chance.

I have done much testing on this manner. there are two pieces to this puzzle that make this an impossible task and a warning for future screen replacements. the two pieces that are matched (excuse my lack of true tech verbiage). the two pieces that are married together are the front camera module and the front ear piece flex from the lcd itself. any change to these two will render the face id useless. not a hard wipe or a complete reinstall of ios will fix this. treat these two pieces as careful as you would an home button on the i6 and up. make a mistake and there is no turning back. on a side note: turns out that every single lcd for iphone 8, 8+, and x has their own SPECIFIC brightness file stored inside the lcd chip itself. change the screen (either using a actual lcd off another device, replacing with oem product or aftermarket lcd and the brightness will always be dimmer. nothing you could do to fix that if you throw away and misplace the original screen that was there in the first place. they do sell machines that can copy the files from the original lcd so it can be transferred to new screen. but I have yet to see them work reliably.

I accidentally ripped a flex on the front camera module. I managed to get the flex unsoldered from the sensor. I plan to order a new front camera module and transfer the flex from it. I don't know if it's been done or attempted, but wish me luck.

Isn't possible, once it's been change then automatically the id will be certainly lost

my iphone Xs max has stopped working front camera but face ID still works fine

so i m thinking to replace only the front camera inside the face Id module by tearing down the module

so my question is will the face ID still work if i change only the front camera inside the module?

So it looks like the Front Camera is it’s own module in the TrueDepth assembly and also uses it’s own Flex Cable. Would it be possible to just replace the Camera and leave the IR Camera and Dot Projector alone and still retain FaceID functionality? Sure seems like it.

Hi my dot projector dosent work if i get that hole part from another iPhone x then my face id it will work or not ?

I work on iPhones all the time and I stopped at the iPhone 10 and above because they're hardware and software secure/ booby trapped. First the earpiece and front facing camera/IR illuminator is booby trapped. Second the LCD has firmware that can be checked and modified during any software update. I've had more than one iPhone 10 malfunction after proper LCD replacement including loss of sound from the earpiece and/or loudspeaker, the phone refuses to turn off (goes through the motions but returns to the home screen), loss of Face ID. After the replacement LCD was installed the phone worked fine. After the software was updated the phone started having problems. The LCD was an aftermarket/non-Apple inc. LCD

Face ID can be one of the hardest things to repair, as you can tell. I would recommend sending into a micro solder specialist.

As mentioned before, you need to transfer the proxy sensor to a new flex cable. There is anither component on the front facing camera, and the idea is the same. You need to transfer it to the new front camera.

This is onyl acheivable via mirco soldering
