Hello Facebook application is the new social network Mark Zuckerberg just launched today for our Android devices, but not for everyone.a new app built by the Messenger team. Hello connects with Facebook so you can see who’s calling, block unwanted calls and search for people and places, currently only available for download in beta users in the United States, Brazil and Nigeria. Hello combines information from Facebook with the contact information we have in our agenda to show more additional information on calls, as his profile picture, his job, where he studies, the number of friends in common and other social information such as if today is your birthday so we do not forget to congratulate you on the call. This application offers a powerful Caller ID .
You can also search for people and businesses on Facebook and call them with just one tap. So if a friend tells you about a new restaurant in your neighbourhood, you can use Hello to find their hours, make a reservation and get directions, all without leaving the app.
Facebook Hello show only social contact information if we have added, If you call a person who does not have the contacts you will not see his/her social information, only it will show how many people have blocked the contact , which will help us to know if we have to take the call or not.
