You're looking at the monstrous Samsung Galaxy Grand 2. With a screen that measures 5.25 inches on the diagonal, it's got plenty of display real estate—but not, perhaps, quite the guts to support it.
Firstly, despite the huge screen, it only packs 800 x 480 pixels—that's just 178 ppi. Elsewhere, there's 8GB of storage, a quad-core 1.2GHz processor, an 8-megapixel rear camera and no LTE. It will run Android 4.3 and come in white, black and pink colour options.
A dual SIM option hints that the phone will be available globally, but prices are yet to be confirmed. Hopefully it will be mercifully cheap. [Samsung]
