If I activate global dark mode and then reboot the phone (mi 9T) the switch is activate but it doesn't do anything, I have to switch it off and on again to make it work again.
* Dark/Night mode: Do NOT report ANY issues regarding this! This feature is officially under development and is not fully ready! We have no control over how it behaves and how it looks! Dark mode on Android Nougat and Oreo does NOT apply to the Settings app. Nothing to be done about it. If Dark mode switches on by itself, it is caused by apps with in-app Dark mode, like Google Messages.
