[In Android beta] Dark Mode Toggle Switch
Dark mode was just released.
This thread now continues for the valid request to be able to toggle ON/OFF the dark mode regardless of the global settings on your phone.
Original post: Mobile apps would look nice in Dark Mode. Reading the System OS Light/Dark theme option as default, then a toggle in settings if the user doesn't want the app to read the System Setting and a custom theme setting for the Tado app.
