Last week, Samsung debuted its Galaxy S 4 smartphone, which includes a 5-inch screen, either a quad cord 1.9 gigahertz processor or an octa-core 1.6 gigahertz processor, and a Super AMOLED screen with 441 pixels per inch. Samsung also showed off some of the key features of the new offering, including Air View (which allows for touch-style interaction without having to actually touch the screen), multitasking and multiscreen capabilities, the expanded notification bar, and the dual camera. See the video below for a full demonstration of these features.
