The Galaxy S IV may well be the greatest phone in the world right now. It has top-notch hardware, shipping with a zippy new Samsung Exynos 5 or Qualcomm Snapdragon S4 Pro processor, and a stunning, never-before-seen 1080p Super AMOLED five-inch display. Its operating system, Android 4.2.2, is slicker than slugs on ice. It also packs new features like automatic translation, a pedometer (and other health functions) and a crazy set of wave-your-hands-in-the-air gestures. It’s all packed into an incredibly slim body just 0.31 inch thick, which is a triumph of industrial design if you stop and think about it. It’s aces.
