Lenovo vibe k4 note, it is the best android mobile I have ever seen, because sound reception is very good. It is very easy to use. Android platform gives it a very good performance. Style and design is unique as speaker is on the front, so sound and display you can all see and hear from one place.
Features are there that much that you will love it probably. Most important is battery, only one demerit is it consumes more battery, when I see a video at 29% in just 1-2 min it becomes 15%. and backside become more warm when I do multitasking. So for this I am little bit unhappy for this product. Probably all Lenovo mobiles get warm fast, even in lenovo vibe k5.
I bought it for 12500/- with vr headset. Till now I have good experience with it for this much value it is worth it.
