Facebook has   recently introduced a new messaging feature called Facebook Chat Heads for   its iPhone and iPad apps. The feature was originally available only for   Android phones and tablets.  
Chat Heads will   reportedly make chatting with friends easier. When a friend sends a Facebook   message, a circular icon with his or her profile picture pops up on the screen. Prior   to the Chat Heads feature, only a notification at the top of the screen   appears upon receiving a Facebook message. 
In both Android and   iOS platforms, the Chat Heads can be moved around the screen. The user can   close the conversation by dragging the Chat Head to the bottom of the screen.   In Android gadgets, the Chat Heads pop up even while using other apps. With   the iOS version, however, Chat Heads appears only while on the Facebook app. 
Facebook has also made   other changes to its iOS app. These changes include new elements on the navigation bar and a sticker capability. Users can also change their Newsfeed   settings to filter updates from   friends. 
In early April, Facebook   has also released a new software called Facebook Home for selected Android   phones such as HTC One and Galaxy S3. The software includes a Cover Feed   feature that displays photos and updates from the Newsfeed to the front of a   user's phone. 
Facebook founder   and CEO Mark Zuckerberg now declares Facebook to be a mobile company as it   has been revamping its iOS and   Android apps for the past year. Users may also expect improvements on   Facebook’s Newsfeed later this year.
