I purchased lenovo k4 note 3 months before, and i’m totally setisfied with that product, in the range of 12000 rupess you will not find a supab phone like lenovo k4, its finger print option is awesome, and camra is also good, and few days before I got an update of android 6.0 marshmello which is very nice. So if you are planing to buy an smartphone and your budget is around so lenovo k4 would be the best option for you.
