You should be able to enable Automatic Dark Theme Android App with the toggle at the very top, after finally launching the app you’ve just installed. The app is set to enable the dark theme at 10 PM, by default. The dark theme will also be automatically disabled at 7 AM. You can enable the option above or simply adjust these timings to follow the sunset and sunrise. This is not an app you’ll be opening a whole lot after the initial set up, though the app itself follows the dark theme toggle as well.

You can also toggle the Switch of the theme only when the phone is locked. This seems like a subtle option to include but it is not. While you’re using an app the system switching to a dark theme would result in the app restarting or crashing. Obviously for the user experience, it is not good at all.  While the device is locked, the App still gets around this by simply doing it. Google’s method was to retract the feature altogether after testing it in beta.
