With this feature, users will now be able to conveniently sort their news feed posts based on the Most Recent, Most Relevant, and Already Seen categories. Firstly, the Most Recent section is present to sort posts in chronological order, the Most Relevant will remain unchanged as it currently is right now and lastly, the Already Seen section will display posts that have already been seen by a user.

— Jane Manchun Wong (@wongmjane) February 18, 2020 At the time of writing, the Tabbed News Feed feature on Facebook is said to be already running live for some Android devices across certain regions. According to a member from the XDA team, the new feature appears on their own device under a separate Home, Recent and Favorites section within the News Feed tab. Facebook has not officially implemented Tabbed News Feed within our region just yet. With that said, do ensure that you have the Facebook app updated at all times to promptly receive the feature when it is made available soon. (Source: Twitter via @wongmjane, XDA)
