Facebook Introduces Caller ID, Dialer App for Android Phones

Facebook Inc. is testing a new application that will act as a caller ID and allow users of the social network to block calls on their mobile phones.

The app, called Hello, will gather information that has already been shared on Facebook. That enables users to see details about callers who aren’t saved in their phone contacts, the Menlo Park, California-based company said Wednesday in a blog post.

Users can also make calls and search for people and information about businesses within the app. Privacy settings match those on Facebook. If a number is shared only with one group, for example, it will be available only to that same group in the app.

Hello is being tested on Android phones. It was built by the company’s Messenger chat application team and comes from Facebook’s Creative Labs, an effort started last year to retain engineers and put more experimental projects into the market.

Few of the Labs apps have received any significant traction. Apps released include Slingshot, a Snapchat Inc. competitor for disappearing photos; Mentions, an app for celebrities to see what people are saying about them; Hyperlapse, an app for time-lapse videos; Rooms, an app for anonymous group sharing; and Paper, an app for consuming news and Facebook posts in a magazine style.
