I 've had S10 for around 3 months and had issue with adaptive brightness for first time today, brightness was pretty low earlier today. I've had a look at this thread and reset the Adaptive Brightness, so will see how it goes.
Having forwarded my error report to the Bugs Department, I was informed that the issue will be resolved in an upcoming software update. Need to see, in my case it has been a bit better lately but still issue at times.
