YouTube is introducing its ‘Dark Theme’ for iOS devices after the popularity of the same feature on desktop. The “Dark mode” will invert the traditional ‘white’ background with the use of ‘black and dark grey’ and make it more night-friendly for users.
This change can be seen in the main feed, settings, video player and other sections. To activate this feature go to Account > Settings > and choose ‘Dark Mode’
You may not find the option right away since YouTube is rolling out the feature as of right now. So if you have a sudden urge to switch or explore, it should be available to you by the end of the day.
‘Dark mode’ has been one of the list of most requested features since its arrival on YouTube’s desktop version.
