Facebook might introduce an Android dialer with call blocking capability
While Facebook Home wasn’t much of a success, they aren’t done experimenting with its mobile apps. A leaked screenshot from Android Police shows the existence of an Android-only dialer app. Its unique feature is that it shows you information about who’s calling you and automatically blocks calls from numbers you commonly block. The app is called Phone but Facebook won’t talk more details about it at the moment.
