Divi_S , via OnePlus 7 Pro , May 15, 2021 : I had a recent update of Oxygen OS 126.96.36.199.GM21AA. After the update, the brightness of the screen goes high and low continuously during usage. The adaptive brightness feature is ON. Without this update, when the adaptive brightness feature is ON, the phone adapts correctly for each new brightness but it doesn't fluctuate continuously until the phone has been exposed to new brightness level. It is uncomfortable to read any content when brightness become too low and too high as our eyes have to be adjusted for it.
