So it's not a Facebook Phone as some had hoped, but Facebook has officially announced a partnership with Google and their Android operating system, unveiling Facebook Home...
If you've used a Windows Phone or Flipboard, the social-centric design of “Cover Feed” should feel comfortable familiar, simplifying the UI of a typical Android device considerably. Live feed updates from friends are available with a swipe and are updated periodically from your home screen, Cover Feed, with access to your own apps and Messenger from your icon at the middle bottom.
Instagram updates, Facebook News Feed, and your friend feed's latest status updates are all served up in a large format style where the usual icon-based system disappears.
Facebook Home will be available for download for Android users on April 12. Facebook also announced the HTC First, the first smartphone pre-loaded with Facebook Home and offering a 4.3" display and dual-core Qualcomm Snapdragon 400 processor (an AT&T exclusive for $99 with 2-year contract).
