Redmi Note 4 comes with a stunning new look with 2.5D curved glass and slimmer, tapered edges. Complete with a bevelled frame and glossy separation lines, Redmi Note 4 is the definition of power – with a touch of class. The gentle 2.5D curves soften the edges of the Redmi Note 4 display, adding to the clean, minimal aesthetic as much as it does to hand feel.

Black is the new black. The brand new matte black finish is a timeless class act.
