How to enable YouTube’s new Dark Theme

Google has just released an update to its YouTube app for Android which finally includes the long-awaited Dark Theme. Google first released the YouTube Dark theme for its website last year, but Android users have felt left out for a while since iOS users were treated to the new Dark Theme feature a few months back. The new Dark Theme for YouTube is included in the 13.35 version of the YouTube app which is currently being pushed out across the globe. If you haven’t received the official update yet, you can install it manually by sideloading the signed YouTube 13.35 APK from APK Mirror. 
If you’re tired of being blinded by YouTube’s stark white UI when watching YouTube clips at night, follow the instructions below to enable the Dark Theme within YouTube.
