I have been using this for the past 1 month and I have made few ponits about the device.
Sound-
It has that special Dolby Atoms Sound in it which is just next to awesome when you listen in headphones. Bass is awesome and also the clarity. In speakers its a bit more than average.
Easy of use-
Its running in the custom UI of lenovi, Vibe UI, which is easy to use. It also had an app drawer and also has few themes, but not many.
Design-
The design is average.
Not that special but the speakers which was in vibe k4 note in the front was better one that in back.
Range of features-
It has given features as in MIUI like dual apps, second space or quick ball.
Durability-
It can last long as its hard.
Value for money-
I would like to rate 9 out of 10.
I would like break down my ponits in Pros and Cons.
Pros-
Excellent rear and front camera.
Good battery life.
3 Dolby Atoms.
Cons-
