Lenovo k3 note mobile is not suitable mobile for me. I purchased it 6 months ago. I am not satisfied it. This mobile sound reception is normal. Look of this mobile is simple. This mobile not supported VOLTE. So I have to face many problems to use jio 4g. I have to on any time mobile data. Its battery 2500kmph but Battery back- up is not sufficient. Battery charging time is long it. Samsung Galaxy is better than it. This mobile is costly than Samsung Galaxy j2 but less battery back up and VOLTE. I really dislike it.
