Google Duo has just made it easier to play tech support to friends and family: the video chat app's latest version comes with the ability to share your screen during a call. To access the feature, simply tap on your screen to see the new screensharing icon above the camera-flip one. Tapping the new icon brings up a prompt warning you that Duo will start displaying everything on your screen. If you choose to continue, a red border shows what the person on the other end of the line can see. A couple of red buttons also show up to give you way to stop sharing your screen whenever you want.
