Face ID and screen brightness dimmed! Ambient light sensor replacement
Solved! I don’t have a simple solution but try leaving it in rice for a week or two.
In my case it was sunscreen residue that came inside the headphone speaker, so i had to pour alcohol inside multiple times (be careful and don’t try this unless you’ve lost hope) aswell as drying it in rice for weeks
My iPhone screen suddenly went dark which I initially thought was just battery juice running out. However, I noticed it actually still was on while using it in a darker room. I could barley see anything so I tried to restart it.
When booting up, it did light up normally but it dropped brightness immediately after. Also, An error message ”Unable to start up Face ID” appeared.
i tried restoring the phone with iTunes and stopped auto brightness and Truetone from settings, without any improvements.
I believe this has to do with the ambient light sensor, because the problem doesn’t seem to be a software issue and it’s affecting screen auto brightness function and Face ID.
I have experience replacing bad batteries and broken iPhone screens but never had to change a sensor component. I read that changing them will lead to iPhone not recognising the new component and losing Face ID. I also read about this recognition problem being solved back when apple released IOS 12. If not, is it possible to reprogram the new sensor? Also, where can I buy this part from?
P.S: Apple fixes it free of charge for apple care and warranty holders but I don’t have that option so it’s going to be a pricey fix with apple. I would rather do it myself if possible.
Thanks in advance!
