When capturing an image with the camera do one of the following:
- If you have the Optical Navi key enabled (default), keep a finger on top of the Optical Navi key to activate the autofocus until a green frame appears. Then press the key down to capture an image.
- If you have the Optical Navi key disabled, press and hold the Navi key to activate the autofocus until a green frame appears and then release the Navi key to capture an image.
In both of the cases the green frame indicates a successful autofocus and the red frame indicates an unsuccessful autofocus.
