Face ID issues after battery replacement (move a little higher/lower)

So after replacing my battery Face ID is no longer able to register my face always saying to move the phone a little higher and then to move the phone a little lower in a loop. I believe the issue is the dot projector. Heres what i’ve tested so far:

  1. putting the original battery back in
  2. cleaning all connectors
  3. reseating back cameras
  4. taking out the sensor module containing the front camera and putting it back in
  5. reseating and cleaning everything on the sensors connected to the screen
  6. called apple support who ran diagnostics and said that they didn’t see any issues with the hardware
  7. cleaned the dot projector with isopropyl alcohol

The front camera and back cameras still work as well as the proximity sensor and ambient light sensor. I also used an old camera to see that the flood illuminator was lighting up. The only thing that refuses to light up is the dot projector. Thanks for the help!

Answer this question I have this problem too

Is this a good question?

Rewa has just recently made a video on this. It cannot be fixed by a 3rd repair. You have to go to Apple but even then they won’t work on the phone because you swapped the battery.
