I bought lenovo K3 note a year ago. It is a very nice phone. Camera is also good. No hanging problems. Little heating problem is there when you use it for a long time, but is manageable. I am using this phone and not facing any issues you can buy it.good performance only problem occurred when you use multiple applications and it remain open in background.also it stop responding when you using chrome browser but it happens sometimes not everyone. Battery life if not enough if you use Internet too much otherwise battery runs full day
