If the Galaxy S III was gently mocked for its design, the S4 has been the unwitting focus of a full-on roast. In a video explaining its design choices, Samsung explains that while the Galaxy S III was inspired by nature, this time it decided to ask the question "how can we change people's lives for the better?" It concluded that it should be more rational with the S4's design, toning down the curves and eliminating some of its predecessor's flourishes. This focus apparently helped the company make the phone thinner while including a larger display. The product designers say they still managed to introduce "emotional elements" through CMF (color, material, and finish) choices, though.
