The back cover is good material and grip for this phone. I love the curved glass across the sides of the screen. Also the body is palm friendly due to curve edges. This phone is super fast and responsive maybe due to its 4 GB RAM and processor.
It has 4G Volte, Superb display colors, Better touch than any Micromax before, Good battery, speaker is fine and very high and what not.
The only cons is camera is not excellent in artificial low lights, but it is works very good in day light.
