A sizeable smartphone designed with productivity in mind. Visually the Galaxy Note 4 doesn't stray too far from its predecessor, the Galaxy Note 3 and has the same fake leather backplate and metallic sides. The Galaxy Note 4's button placement is also the same and the Galaxy Note 4 has a physical front-facing home button and volume and power controls on its right side. Under the hood, though, Samsung has made a few changes, one of the biggest of which is the inclusion of the custom fingerprint scanner debuted on Samsung's regular-sized Galaxy S5 handset.
