In a test build of its mobile software for Android devices, Facebook seems to be finally headed down the flat UI path that Twitter and a host of other apps have already traveled. Aside from that, navigation in this build has been shuffled around to make room for title text and a search icon according to the findings of the folks over at Android Police. Buttons for News Feed, friend requests, updates, notifications and the complete menu are situated just below with controls for both status and photo posts alongisde check-ins relegated to the bottom of the screen. Of course, this is pre-release software and the aforementioned tweaks may get scraped much like Twitter did with a beta version last week before the official rollout.
