Now Facebook Messenger seemingly due to prolonged external nagging has started public testing Dark Mode in certain countries. In May last year, the social media giant had announced a major design change in its messenger app, including the dark mode. This isn't the first time Facebook Messenger users are getting dark mode. Earlier in September last year, some users reported getting dark mode in the Messenger app before it was rolled back.

 Facebook promised a dark mode in its Messenger app last year, and it seems that the company has now started testing the feature. According to well-known app teardown expert Jane Manchun Wong, Facebook Messenger is showing 'dark mode' option but only in some countries, and it's still incomplete. The screenshot included a picture of a dialogue box saying, "While we put the finishing touches on dark mode, it won’t appear everywhere in the app." The screenshots made it clear that the social media giant is secretly working on the dark mode feature and this year we might see the new tool rolled out for its Android and iOS users.

Dark mode makes it easier to look at the phone’s screen in night time and also extends the battery life of Android smartphones.  Google has confirmed that use of bright colors within apps drain the phone’s battery and reduce eye strain and. The Dark Mode will reduce battery consumption on smartphones because there will be minimum colours used on the display. Once Facebook finishes the final touches, we shall see the Dark Mode feature on its messenger app.

The dark mode feature will turn the background colour to black and its text to completely white. However, the icons will still remain coloured, with only the white spaces transformed into black, or as it's called  Dark mode. Rival WhatsApp also seems to be testing Dark mode for its app on Android and ios though the feature is still in beta।
