After starting a dark mode for the desktop surface, Facebook confirms that a dark mode is also being tested for its mobile apps. As first noticed by SocialMedia todayFacebook has made dark mode available to a very small percentage of people worldwide, a spokesman said The edge in an email Sunday. The mobile version of the dark mode that Facebook introduced for the desktop last month is said to "reduce glare," especially in low-light environments, the spokesman said. There is still no timeline for when dark mode will be available to all mobile users.
Users who already have the new dark mode on mobile devices have tweeted screenshots of how it looks:
It's a bit surprising that Facebook took so long to introduce a mobile dark mode. The Instagram and WhatsApp apps and Facebook Messenger already have a dark mode. Twitter has had a version of night mode for its Android and iOS apps for some time, and even Google introduced a dark mode for its app earlier this year.
Low-light and dark-mode variants that allow users to change the background color of an app window to black are popular not only because they make it easier for some users to view apps and are more aesthetically pleasing, but also because most dark modes versions can also help extend a device's battery life.
