Samsung unveiled the Galaxy S4 at an event at New York’s Radio City Music Hall on Thursday. Samsung’s latest handset has a 5inch 1080p screen. The screen is sharper but smaller than the Samsung Galaxy S III. and it comes with a built-in infra-red diode.
The S4 also has several new technologies intended to help users interact with the phone. For instance, the screen now senses fingers hovering just above the screen, and some applications react. The Mail application shows the first few lines of an email when a finger hovers above it in the list, and the Gallery application shos an expanded thumbnail.
