This app allows you to change the current System's Dark Mode by using a Quick-Settings tile.
To insert the above-mentioned tile in Quick-Settings, open the Quick Settings and manually add the tile in the list of available tiles. Please note that not all Android versions/devices allow apps to change the System's Dark Mode. In this case the only solution remains to use the Android's System Settings.
