Why is my iPhone Face ID not working and how to fix it
Hi Unfortunately there are few things we can try but here’s what to try Your best bet is to try reseating and cleaning the Face ID connectors with isopropyl alcohol Here’s a guide for getting into it iPhone 12 Front-Facing Cameras Replacement Unfortunately that’s really your only shot unless you can find someone who specialises in fixing this sort of things as this part isn’t really fully replaceable as apple pairs this part to every individual iPhone which makes makes things much harder so if you want the issue fully fixed and can’t find someone to fix the component you will have to get apple to fix it as they are the only ones who can pair a new Face ID module. Hopefully this helps Any questions please ask Thanks:-)
