Facebook Is Testing Moving Function Bar to Bottom of Screen for Android App

In the near future, Facebook app users on Android can find their function bar on the bottom of the screen, if the testing goes successfully. That way it will resemble the layout on iOS more.

As per Android Central, moving the bar to the bottom could be intended to make the navigation better and eliminate the need to use both hands while on the app. The first picture is the current layout, and the second is what is being tested.
