My iPhone x just got water damaged and my face id doesn’t work. But i’m not getting any message that says “Face ID not available”. I checked flood illuminator and dot projector by ir camera and only flood illuminator works. Is it possible that only the IC of dot projector has got damaged (not the part that produce some sort of unique id, only the part that emits ir dots) and by replacing the dot projector IC it would work?
Dot projector upper layer can be replaceable.It`s complex but can be fixed able.I have done it.
No, unless you go to Apple directly, the dot projector is irreplaceable.
To fix a damaged dot projector, you need to transfer the encryption chip as I learned from below.
And to test Face ID parts, you can follow steps in the repair guide: Troubleshooting iPhone X Face ID Not Working ‘Move iPhone a Little Lower/Higher’
