My friend is having this phone and he is using it from 10 months.This many days are enough to test mobile.
He had purchased it from flipkart the shopping giant.they delivered on time.Although packing of the product was good.
Now coming to the product.It was working fine till he did not damaged it?.Performance of the phone was good, we played heavy game like mortal combat, but we did not faced any lag.If you leave 5, 6 apps in background you will not face any type lagginess.Performance of the phone is up to the mark.They provide you with timely update.
Lenovo ui that is vibe ui is a good looking and user friendly UI which works excellent.
We did not face any lag in day to day usage.
