The Galaxy S4 has so many features that Samsung could probably release a CliffsNotes app for all the goodies stuffed inside its flagship phone. You can use gestures to answer calls and skip music tracks — without touching the screen — control your TV, translate multiple languages and a whole lot more. The 13-MP camera is more than just sharp: Its Eraser mode also lets you remove would-be photobombers from your pics. And you can shoot using the front and back cameras at the same time, which is great for sending digital postcards to Mom and Dad. It also doesn't hurt that the 5-inch 1080p AMOLED display is one of the most vibrant we've ever seen.
