A new version of Messenger for Android, famous application designed directly from the developers of Facebook, appeared in April 2013. With it you can chat with a friend even if that application is not open in the foreground, using the chat Heads.
For iOS devices, this innovation is largely restricted to follow the policy outlined by Apple, so that Chat Heads that were introduced only work if the application is open in the foreground. If you want to use this function, even outside the application itself, you can be installed via Cydia the MessageBox, package available only on jailbroken devices.
Also in 2013, the CEO, Mark Zuckerberg, announced the launch, scheduled for April 12, Facebook Home, multifunctional application available exclusively on Android smartphones. It is a graphical interface that allows at any time to access all content posted by your friends and chat with them, especially during normal use of the smartphone. The application for Facebook Home is only available for the HTC One, HTC One X +, HTC One X, Samsung Galaxy S3, Samsung Galaxy S4 and Galaxy Note, while versions for other devices will be announced at a later time.
