The YouTube app for iOS received dark mode earlier this year, with Google promising to roll out the feature to Android devices in the future. The search giant is apparently making good on that promise as dark mode has appeared on some handsets running Google's mobile operating system.
The rollout is occurring in phases and there's no definite timeframe that details when it will be completed. If you have received the update, the dark mode toggle can be accessed by navigating to Settings (by tapping on the user avatar) > General section of your Android device.
Like dark mode for iOS and the web version of YouTube, the Android version allows you to change the white backdrop into a dark color and select their profile header. The dark UI is especially helpful during the night time as it reduces eye piercing glare, thus helping to prevent strain on your eyes while watching videos.
The feature has increasingly become a popular addition to several apps, with Twitter having recently introduced the Night mode to its Progressive Web App. Microsoft is also rolling out a dark mode for Outlook on the web. YouTube first unveiled the dark mode in August last year along with a range of other capabilities and redesigns across its desktop and mobile experience.
