Samsung tonight announced its flagship iPhone competitor, the Galaxy S 4, at an event at Radio City Music Hall in New York City. The new smartphone is set to launch in April on all four major U.S. carriers. The new phone gets a slight screen size increase to 5" from 4.8", with a 1080p display at 441 pixels per inch (compared to iPhone 5's 326 ppi) that Samsung is calling "Full HD Super AMOLED." The phone also houses 2 GB RAM, a 2600 mAh battery, a micro SD card slot for expanded storage (in addition to the 16GB, 32GB and 64GB variations) and a rear 13-megapixel camera. There is also a front-facing camera that can record 720p video. Image via
