If Samsung’s Android lineup is feeling a little sparse on AT&T, don’t worry… there’s about to be a new flagship in town. We have just exclusively received a photo of an unnamed Samsung device complete with sliding QWERTY keyboard that’s headed to AT&T in the coming months. While we don’t have much to go on, the device will sport the four-button Android layout as opposed to Samsung’s typical three-button layout at AT&T’s request, and the QWERTY keyboard even reflects that.
