Android tip: Your volume buttons can double as a camera shutter - Pocketables. Most of us are using our phones as our primary camera. One of the annoying things about the cameras, however, has been the lack of a shutter button. We were all used to pressing it with our right index finger to shoot a photo. Newer versions of Android, however, have made this a non problem. While you can get apps to make your volume button double as a shutter, I am happy with the built in Kit Kat command to tap to take a photo. Just tap anywhere on the screen to activate the shutter, and, boom, photo taken. Now, get out there and take some pictures.
