Try turn off adaptive display

Display might dims down due to overheating try to cool your device down after that the brightness will go back to normal

I like you answer.
But the issue you elaborate happened some times.
Moreover the mobile is in AC room.
Using cover makes sometime display issue.
Last 2 days I face the issue without cover 🤷🏻‍♂️😔
