Following the launch of its latest smartphone, the Galaxy S4, Samsung is offering a closer look at some of the device's new features via one of its YouTube channels. 

We mentioned both the Dual Camera and Sound & Shot features in our recent hands-on with the Galaxy S4. Dual Camera allows you to capture either video or still images simultaneously. As one camera shoots the primary image, the other camera is also capturing an image that can be inserted into the primary image in a smaller window. Sound & Shot allows you to automatically record sound for nine seconds while you take a shot. In manual mode, you can pair a longer recording with an image, though the sound is captured after the image is snapped.
