Front cam not working after screen repair

I repaired a iPhone 15 Pro Max last week and placed a new screen. I had no passcode so could not test it.

Now the iPhone has come back and the front cam isn't working. In the camera app it just doesn't switch from back to front camera. And in other apps or configuring face id it is just a black screen.

I tried restarting the device and resetting the settings. Also updated the device with IOS18 from 17. I also ran diagnostics and in the camera image and face id test it says that the camera is not connected. So I opened the device and reseated the connectors. Still nothing, than I cleaned the connectors on the mainboard as well as both flex cables but still nothing. I could also find no damages on the flex cables or camera modules.

I also connected the device with 3utools and the verification report gives a score of 100 but under front camera it says N/A (not available).

Anyone have any idea what the problem could be? The device was severely dropped to be fair and outside of the touch screen the LCD itself was also shattered.

Do you think replacing the front camera incl. the IR camera would work? I can order a pulled part (so it's original) but will the face id work again after running the repair assistant?

Thanks in advance!

I replaced the front camera incl. IR sensor today with a pulled part today. After that cam still wasn't working so I did a DFU reset. After that the front cam worked but sadly no face id. Ran the the repair assistant and diagnostics but sadly no working face id.

Does somebody have an idea what I can try to make it work? I read somewhere that you could dissemble the sensor it flex from the front camera but cannot find any instructions on how to.

Just fyi, I placed a new front camera + IR flex (pulled part). But both didn't work on the latest IOS also after running the repair assistant.

As a last resort I did a DFU reset and the front camera worked but no face ID.

So I cut out / opened the metal bracket containing the original IR camera and replaced only the front camera flex from the pulled part. After that everything worked as normal.

So even with latest IOS it looks like the Face ID / IR is not swappable.

For future repairs, always test the phone in front of the customer prior to repair. I understand you couldn't based on your description. I always check the following.

  1. Make a call testing ear speaker, speaker phone, and mics.
  2. Both cameras.
  3. Face ID.

If the phone is blacked out, I let the customer know that the drop and or damage sustained could have caused other issues that are unknown until further testing.

To answer your question, yes, an OEM pull is supposed to work now using the repair assistant.

Thanks for your answer! I normally do that too, or at least (if possible) before I start the repair (or during/after). But I was not in direct contact with the user in this particular case.
