Recently i have replaced the back glass of my iPhone 12 as far as I know face id should not be affected by it but still it doesn’t work. It did work before the replacement.
O have on of those heat tables so i can remove the back glass a bit easier.
when i want to do the face id it says that it is not available

Hi furkan,
So what method did you use to remove the back glass? Heat gun? That's the most common way for us home DIY-ers to do it. The downside is that there are a lot of components on the other side of that sheet of metal the glass is mounted on, and it's not at all uncommon for those components to get damaged as a result of the heat used.
By far the safest way to do a glass replacement is to basically gut the phone before starting so you don't get heat damage on any of the components; of course once you've gotten to that point you might as well just buy a replacement housing. The use of a laser to burn off the adhesive is what the professional repair shops use, as it doesn't transfer much heat to the inside of the phone, but that's not something most of us have access to.
Can you be a bit more specific on what isn't working with your Face ID? Is it not available, or it's telling you to move a little closer/further away, or what?

I am having the same issue, because I did a back glass on a 13 mini however now the phone says Position your face within the frame.
It’s not available
@miskaylaxjames Generally that particular error is related to the front camera. Did you also do a back glass replacement? It's possible you overheated the flex cable on the selfie camera causing damage. Does the camera work otherwise?

Open the phone and remove the front camera, Face ID module and check you haven’t damaged the ribbons.
