S9 Sudden Change in Brightness Levels [Solved]

[JohnyLivinston]

Unusually my S9's brightness has now spiked up although I am on Auto Brightness. This is very unusual that in my usual office setup the brightness remained very comfortable. But now it's higher than usual. Anyone else felt the same?
Device runs on February Security update. 

Solution:
When Adaptive Brightness is turned on, it learns our usage pattern and once learned, it sets a value. And that's what has happened in my case. If its learnings are not favorable, we have the option to reset the usage patterns from settings under Adaptive Brightness. After I reset it, it's back to normal. It's the lack of awareness of such wonderful settings such issues have come. Rather the phone is perfect. I thought I explored my device in full. But surprised I found something new. This is with regards to Pie update I guess. Thanks.

I kept an S8 in parallel and tested the same. S9 spikes high than it was before.

Actually I found the solution just now. When Adaptive Brightness is turned on, it learns our usage pattern and once learned, it sets a value. And that's what has happened in my case. If it's learnings are not favorable, we have the option to reset the usage patterns from setting under Adaptive Brightness. After I reset it, and it's back to normal.
