I Just bought thuis phone few days back as I was planning to buy K4 or moto G4+.
But I am glad that this was launched and I bought it within a week.
Its a good phone in this range as we have another phone from lenovo subsidiary firm Moto G4+ in the same range, but in comparison of Moto G4+, it has better battery backup, camera.
It doesnt lag and 64GB card run smoothly.
Battery stays 1.5 days with wifi on. As I use WIFI in my office and at my home as well.
Smoothly run Asphalt and modern combat 4.
