Auto practice does not work properly when I am using screen with some white background for example browser. auto brightness increase brightness almost to 70% in dark condition also.
As per your query, we want to inform you that as of now auto- brightness feature is unavailable on Samsung devices, however, you can set Adaptive brightness to set the touchscreen to automatically adjust its brightness based on the surrounding environment.
Path: Settings app> Display >then tap the Adaptive brightness switch to activate it.
