It seems that Facebook has begun testing a version of its app that has a little bit of Material Design. The aspect that stands out of Material Design in this test version are circular floating action buttons in the bottom right corner of the app. This button brings up options for a new status, photo or check-in.
This action button replaces the current bar at the bottom of the app. This new Facebook version could be a little bir far from conclusion but at leats this shows that Facebook is considering a change and wants to test the waters before it overhauls the app. This version will only be available for Facebook’s selected testers so everyone else will have to wait and see if Facebook decides to implement Material Design.
