Facebook is testing bringing voice and video calls back to its main app, seven years after it separated them to its side Messenger platform. Some users, including those in the US, will be able to start enjoying the feature from their main Facebook app this week. The reintroduction of the feature is currently only in trial mode, and is designed to reduce the need for users to switch between apps when trying to keep in contact with friends. It comes after Facebook tested the reintroduction of a limited version of the Messenger inbox in the main app last autumn. Connor Hayes, director of product management at Messenger, told <i>Bloomberg </i>that Facebook is beginning to think of Messenger as a service rather than a standalone app, and as such users can expect to see its features slowly become integrated across Facebook’s platforms, including Instagram, Oculus and Portal devices. He said Messenger is the “connective tissue for people to be together when apart, regardless of which service they’re choosing to use". Facebook started enabling messaging capabilities between Instagram and Messenger in September 2020, and has plans to introduce WhatsApp into the mix, too. Facebook’s chief executive Mark Zuckerberg has argued that integrating the company’s messaging services would be beneficial to users, allowing them reach more people and reducing the need to download or jump between separate apps. Facebook confirmed to <i>The Verge</i> that users in several countries would be able to start using voice and video calls in the main Facebook app, for stressed that for a “full-featured messaging, audio and video call experience, people should continue using Messenger.”
