Pros of the phone:Great User Interface, Sound quality is good, Display is nice.Cons of the phone:Phone lags while playing high graphics games, Camera is average not too great, Lotof bloatware in the phone, Phone gets heated while playing games, Minimum 1 GB Ram is always occupied for OS and preinstalled Apps, Battery back up is average.If you want to buy a Lenovo phone then buy Lenovo K4 Note which is much better than k3 note and sar value is also less than k3 note.
