Google already offers a way to filter calls suspected of being spam. But this new feature goes further, letting you get more information before you pick up a call from a questionable number. Spam calls and robocalls, which use autodialers, are on the rise, in spite of efforts from the Federal Communications Commission to curb them.

Ridding the world of unwanted robocalls is tricky business, since some legitimate communications are made using automated call technology. Those include weather alerts and messages from schools, public utilities and political organizations. Google's Call Screen feature offers another tool that could make it easier to help distinguish legitimate calls from unwanted spam.
