Cydia has got another new awesome tweak called “camera Buttons”. What it does is that it lets you take photos and shoot videos on your iPhone using volume keys. The tweak gives you complete touch-free control of your iOS camera app. You can easily configure the volume up button, volume down button, and shake action to your desired function from the settings menu.
Here are the options available for CameraButtons:
Take Photo:
Switches to photo mode if not already in photo mode and takes a picture.
Take Video:
Switches to video mode if not already in video mode and begins recording.
Take Photo/Video:
Snaps a photo or starts video recording depending on which mode the camera is currently in.
Toggle Flash:
Switches Flash between Off, Auto, and On modes for compatible devices.
Toggle HDR:
Switches HDR mode On and Off for compatible devices.
Toggle Camera:
Switches between the front and back cameras for compatible devices.
You can download CameraButtons from Cydia via BigBoss repo for $0.99 only. You can also set up a lockscreen launch function which lets you open the camera straight away from your lockscreen by holding own the Volume Up or Volume Down button.
