Finally an official dark theme, this should've been released years ago already. White themes are only good for burning your eyes, even with the lowest brightness settings. Same goes for desktop, white websites aren't that comfortable to be read. Hoping GSMA also introduces a dark theme.
I had this long time ago on my android, if you have root just download substratum and swift black theme and install layers.
