Face ID not working after water exposure
I waded into some water (depth maybe 30cm above iPhone level), incorrectly assuming my phone would be fine. The phone shut off, and I just let it sit and dry out for the next few days. After turning it back on, the phone got very hot so I turned it off again.
After a week, it no longer got hot but got an occasional green vertical line. Again, phone off, and after half a week no more issues.
All functions of the phone now work, but FaceID does not work anymore. I took it to the Apple store, and whilst they said that all it would take would be to reseat the camera unit (or something along those lines), they would not work on it due to evidence of water damage.
Any insight or advice would be appreciated, if its an easy fix id like to get in there and sort it out! After all, FaceID is half the reason I love the new phone.
Is dit een goede vraag?
