Samsung could resurrect the clamshell (flip-phone) form-factor in its upcoming device named Galaxy Folder (model: SHV-E400K). Roughly sketched up above, it mates the form-factor with the latest mainstream smartphone technologies the industry has to offer.
To begin with, it features a pair of 3.7-inch AMOLED touchscreens on either sides of the top half, featuring WVGA (800 x 480 pixels) resolution, each. The bottom half holds a physical numerical keypad, a D-pad, the primary camera, and a few other of the device' main components.
Under the hood, the Galaxy Folder runs a Qualcomm Snapdragon 400 dual-core SoC clocked at 1.20 GHz, 2 GB of RAM, internal expandable storage (we expect at least 4 GB of it), and cellular connectivity that includes 4G LTE. Android "Jelly Bean" (unsure which version) is at the helm.
