I brought a lenovo k3 Note a week before by exchanging my old lumia 520 Phone for 2500 INR on flipkart. Thus the phone costed me just 7500 INR.
The phone has a great camera quality. I even tried clicking selfies in night, the photo quality was good. The battery backup of the phone is great.
The best part of the phone is that You have a virtual phone inside the phone. And that is referred to as safe zone. Thus u have two zones of the phone, namely open zone and secure zone. Thus u can keep ur private photos and videos in the secure zone.
