Google Search has been updated for Android with a unique new feature that let's you launch your camera simply by speaking a quick command – yep, sounds like you don't need a dedicated camera button after all.

Using the standard "OK Google," command, you'll naturally activate Google Search. Then, simply say "take a photo" or "take a video" and the camera will automatically launch. As you may already know, the voice activation for Google Search works best on the Nexus and Google Play Edition devices, but with some extra legwork you can get it running on plenty of phones and tablets. Or, just tap the microphone and say "take a video."

It's probably not needed on some devices, however. With the Moto X, for example, you can simply jiggle your wrist to launch the camera, which eliminates any need to use your voice. Still, this is a good option, especially if you want to snap a photo without touching the screen – like when you're trying to grab a selfie, or after you've eaten a handful of potato chips.

You should find the update inside Google Play now, otherwise it'll probably just download automatically in the background. Android Central says it should work on both Android 4.4 KitKat and Android 4.3 Jelly Bean devices.
