Looks like Sprint really is prepping a 5-inch Android flagship of its own: the Vital. Thanks to an anonymous source, Engadget's received a motherlode of details on the upcoming, white-labeled device, giving us a glimpse at everything from renders to a slickly produced promo video. Based on the information at hand, the ZTE-made Vital should rep an HD display (resolution unspecified) of the 5-inch variety, an unnamed dual-core processor clocked at 1.5GHz and paired with 1GB RAM, 13-megapixel rear camera, 8GB of internal storage (expandable via microSD), NFC and a healthy 2,500mAh battery. As you can see from the image above, the Vital will also be running what appears to be an unskinned version of Android Jelly Bean -- version 4.1, according to the documents -- and will run on Sprint's 4G LTE network. We're not so sure the Vital's going to sway consumer interest away from its more bold-faced rivals (i.e., HTC One and Samsung Galaxy S 4). But competition's always a good thing and if Sprint can price this one right, it might even have a fighting chance. Hit the break for the promo video.
