To celebrate the launch of the brand new Samsung Galaxy S4, EE have released a new hands-on video showing off the phones new features, including the full HD Super AMOLED display, eye tracking and air gestures. The phone promises to be one of the biggest tech launches of the year, and because it is Samsung's flag-ship unit, if you're a phone aficianado, chances are it's already on your radar, but the video below offers a comprehensive look under the bonnet of the phone, which promises a slicker experience with a raft of new features. And size is one of the key issues here - not only of the launch, but also of the phone itself, which boasts a giant 5" display, which is crystal clear thanks to its Full HD (1920 x 1080) resolution, putting it on a par with the biggest HD TVs. The phone also features a massive 441 pixel-per-inch count, which outstrips the iPhone. Coupling that with a fast processor, 4G compatibility, and two cameras, one with a high-resolution 13 megapixel sensor, and the other, a two-megapixel front-facing camera - there's even an infra-red transmitter that turns it into a TV remote control if desired. All in all the hardware is hugely impressive. http://youtu.be/kWV_dZX89Mk
