To activate the dark theme, head to the YouTube app settings and slide the little switch next to "dark theme" to the right ... and hey presto! From there, you'll notice the background of the app darkens to a deep gray color.
YouTube has announced that it's rolling out Dark Mode to its apps for iOS and Android devices.
Youtube is going dark on iOS and Android with a new update. The company did not set a firm date for Android devices to get the new dark theme.
YouTube first introduced a dark theme on its platform last summer with an update to the web-app and is introducing it to mobile for the first time with this update after a brief testing period.
YouTube looks much better with the dark theme, and the viewing experience is definitely superior. Offering a dark theme on YouTube also makes sense from an aesthetic perspective because it gives the app a more cinematic feel.
A lot of people who aren't subscribed to a music streaming service like Google Play Music or Spotify like listening and discovering new tracks on YouTube.
