Marco unboxes the BLU VIVO IV, the new flagship from the company based in Miami. The VIVO IV packs a 5-inch Super AMOLED 1080p display, an octa-core 1.7GHz processor, 2GB of RAM and a design that makes the device the thinnest smartphone on the planet, measuring in at only 5.5mm.

The good news is that just because it's hin doesn't mean the battery is tiny: the VIVO IV's juice pack is rated at 2300mAh.
