Group conversations are better than ever
Send photos or emoji, see when people are engaged in the Hangout and message friends anytime, even if they're not connected right now.
Get together over Video and Voice
Turn any Hangout into a live video call with up to 10 friends or simply search for a contact to start a voice call from your computer.
