The led light that come from the notch

As I said, a camera can see IR light, but the human naked eye cannot. There is nothing wrong with your phone.

And how do you know this? You cannot see that light, it is infrared.

You're welcome

You should not be able to see the Infra Red light from the notch. If Face ID works on your phone it works just fine. Some cameras are able to capture the light, but the human naked eye should not be able to see it.
