Why does the screen flicker when adjusting the brightness on the POCO M6?

In a dark environment, setting the screen brightness to the maximum and then gradually lowering it can make your eyes uncomfortable as they adjust to the changing light levels. This abrupt transition can strain your eyes and lead to discomfort.
To mitigate this issue, it is recommended to enable the Auto-brightness function, which automatically adjusts the screen brightness based on the surrounding light conditions. If you find the adaptive brightness setting uncomfortable, you can manually adjust the brightness levels to a more suitable level that minimizes discomfort and provides a more pleasant viewing experience.
