wybitny2 I agree with that. But that duplicate control in the Android menu is on a higher level than the duduOS menu. So it allows me to have the backlight automatically change with the time of day, even if the day/night mode in duduOS is set manually. This means that I can have absolutely all duduOS menus without a white background. And as I mentioned, I don't like having any screen with a white background, either during the day or at night. For example, if you want to change an equalizer setting, during the day, it appears with a white background.
