Facebook has splintered chat away from the main Facebook app to move people over to its Messenger app. However, the company is looking to bring people back to the primary Facebook app by adding voice and video calls.
Bloomberg is reporting that some Facebook users in the US will be able to make and receive calls directly from the Facebook application. This should make it so anyone with the feature won’t need to frequently switch back and forth between Facebook and Messenger. However, the feature is currently in testing, so you may not see it on your Facebook app yet (if ever).
This might be just the beginning of Facebook bringing back features to the main app, as a tiny group of users also received the Messenger inbox in the main app last fall.
