Facebook has just release a new update for the official app and also the Facebook Messenger app for Android in preparation to welcome the launch of Facebook Home.
If you check on the Play Store, it will prompt you to update both apps. Facebook has promised to launch Facebook Home, their very own customized launcher for users to install and literally take over the original interface of the Android today, which is 12th April.
After updating, you can go to the settings under Facebook app to enable Facebook Home. It may not be available to download until the app is released on the Play Store but what you can use now are Chat Heads.
Go to Facebook Messenger and enable ‘Chat Heads’ under notification settings. New messages will appear on your screen on top of whatever app you are looking at. Just like the screenshots above.
