As I told before, UI 3.1 seems to have solved the issue.

Thankyou.   Probably need more than a single person's experience with 3.1 to be sure though.  It's definitely promising.

While we wait for the OneUI 3.1 update hoping that it fixes the problem, Samsung representatives please have a look at the video linked below for a full depiction of the issue. Note that the phone is indoor and the ambient light does not change, still the auto brightness does. S20FE Exynos with the latest available update installed.

I am having exactly the same issue. Brightness sensor jumps to zero lux every other second, which makes screen brightness change constantly. Extremely annoying.
