An update to Google's search app lets Android users launch their phone's camera, in photo or video mode, with a voice command. "With the Google Search App on Android, you can just tap the microphone or say 'OK Google,' then 'take a photo' or 'take a video.'

I couldn't get it to work with video in my test today on a Nexus 5, but the "take a picture" and "take a photo" commands worked, presenting a choice of installed camera apps to finish the command.

That's potentially a lot harder than just tapping the camera icon. Read the full story at CNET.
