New Facebook app Hello will be connected with Facebook so you will know everything about people who calls you even if you doesn’t have the caller saved in your phone.
Hello recognize the caller for you and tell you whatever the person has accessible on Facebook for free. Also there is function that is maybe even more useful and that is blocking of callers. If you don’t want to talk with someone you just block caller and no calls from this person reach you.
It is all connected together and if people start using Hello Messenger will benefit from it too.
