When the phone turns on the auto brightness in the notification center, and moves from a place with dark ambient light to a place with bright ambient light or from a place with bright ambient light to a place with dark ambient light, the screen brightness adjustment does not keep up with the light changes, and there is a delay.
Since it takes a process for the eyes to adapt to the change of light, when the phone automatically adjusts the screen brightness, the brightness will not change immediately and the brightness change will be completed within a few seconds. This is a normal phenomenon, please feel free to use it.
