My face ID is not working after updating my phone to IOS 17.1.1 please solve the issue

My Face ID stopped working after software update to 17.1.1

You're just saying that dozens of Apple customers are facing the same issue directly after updating to the most recent version and it's all a mere coincidence? That's ridiculously rude. Straight in your face.

If Face ID isn't working for you, there is most likely something wrong with your TrueDepth camera. First, look at these two articles for help. If that doesn't fix the issue, then make an appointment at the Genius Bar to have your camera issue diagnosed.

Mine stopped working so I thought but it is actually working but through the back cameras. It will let me set up the Face ID using the screen side camera. But when you use an app and it looks for your face it is accessing to he back side camera. So I have to stand in front of a mirror to get in.
