Good phone.
I am using it for the past 4 months and feel good using it.
Camera quality, battery backup are good.no heating problem( which most of the costly mobile phone has) .
Very happy using the phone. RAM is 2 GB and with 20 apps running 700 MB remains free It has removable battery of around 3000mAh and this runs easily for 2 days with internet running 24 hours. Many competitors in this price segment are even offering 5000mAh battery.
But keep that in mind they are non-removable battery and when mobile hangs, you have no option to force power off and ofcourse you cannot replace battery in future. Price is the best on Flipkart since Lenovo launched K3 note with Flipkart as selling partner. You will not find Lenovo K3 note in most of the shop for the same reason. Camera is super and 13MP is good enough to capture the moments in good quality. I do not compare smartphone cameras with real SLR camera. 5 MP camera for selphie is good enough and it works fine even on dim light. Touch screen panel is good and it has good sense of tough. Overall worth buying when you have price segment of INR 10000 to 15000.
