This is a new issue a few of us have brought up and we are investigating, this also appears to be an issue with the iPhone 8 and 8 Plus.
This is also an issue I have on my personal X.
I replaced my cracked screen with an original screen pulled from another X, and the ALS (Ambient Light Sensor, responsible for auto brightness etc.) no longer works, myself and a few others have also noticed that the brightness also isn’t as bright as it used to be overall.
If you put on your original screen, the ALS works again we have found.
So this is definitely to do with the screen being replaced and not user fault.

When we have an idea how to fix this, we will update accordingly.
