There's also a data saving mode for mobile data networks and WiFi on Android in certain markets, including Brazil, India and Indonesia. Google says when it's active, both you and the person you're calling will save data. The feature will arrive in more regions in the coming months.

In addition, Google is letting you spice up your video voicemails. On Android (and soon on iOS), you can add text, emojis and doodles to your messages.
