Android: With touch screen smartphones, volume buttons are among the few physical keys you can press. QuickClick makes it easy to put them to use for more than volume control.
For example, say you want to take a photo with your camera quickly. You can set it so that if you hit the Volume Up button three times, it will automatically take a photo (with a preset choice to use autofocus or not) and save it to a predetermined location.
QuickClick offers flashlight, photo, video, dictaphone, call shortcut, message shortcut, sound, configuration, app shortcut, and the ability to set a Tasker action for more automation. Each of these options has more choices, after which you need to select a sequence of clicking the volume buttons, such as Up, Up, Down, Down. And that's it. You can review or delete any of the actions at any time. And yes, it can be activated even if your screen is locked.
