Dear friends, I have used this mobile and this is good mobile phone. Display quality is good, camera quality is good, battery backup is average, sound quality is very good with Dolby Sound, look and design is very good, very slim and good looking, but build quality is average. Phone performance and speed is average because k3 comes with 2GB RAM so it’s little slower. For performance I will give 3.5 point out of 5. But overall Lenovo K3 is a good phone. People who are looking a average uses phone 7-8k budget with good display and camera can go for this. Thanks.
