Facebook looks to be testing a new feature that will allow users to launch WhatsApp directly from the main Facebook app.
Last week, a new dedicated WhatsApp button started to appear on some Android versions of the Facebook app, which when tapped took users straight to the popular chat app, the Next Web reported.
The new WhatsApp button can be found in the menu section of the app and has so far been available to some users on Android.
There has been no formal announcement by either Facebook or WhatsApp on the new feature and it is not clear if the feature will also be available to iOS users or all Facebook users across the board.
The feature was first spotted by eagle eyed Facebook user Arvind Iyler who said he noticed the button after changing the language settings on the Facebook app to Danish.
The Next Web noted that Facebook has previously chosen Denmark when testing other new products.
Facebook has recently tested a similar feature with its other subsidiary, Instagram.
Earlier this month it was also revealed that Facebook is working on another new feature called Instant Videos.
The new feature will help users save on mobile data when watching videos in the Facebook app.
Instant Videos will load faster than typical mobile websites as it downloads Facebook videos while connected to WiFi, rather than using mobile data.
Instant Videos will reportedly work in the same was as Facebook’s hosted news content feature Instant Articles.
