Lenova Vibe K4 Note review - Not a disappointing mobile

Finally received Lenova Vibe K4 Note today morning from amazon, bough from flash sale.

Mobile look/style : (8 out of 10)
Mobile exterior is nice and finish is really cool.

Sound : (6 out of 10)
In full sound music is not clear, in 75 % sound, steroe speaker magic will live.

Offtopic:
Motorola G2 have twin speakers, compared both sound, still Moto G2 sound is perfect and crystal clear,

Camera : (7 out of 10)
Front camera is more than expected, and pictures are cystal clear.
Rear camera is ok, but not best.

Works poor in dark area or dim area, compared to Moto G2 and Redmi Note 4G

DIsplay/touch :
Display is really nice and HD videos are checked, which are played flawlessly without lag, still have to check high bitrate videos.
Touch sensitive is par with top branded mobiles.

Charging :
just plugged now, as 2A charger is supplied, hope it charge quicker.

Gaming :
still have to install CPU intense game, will post review soon

Finger print sensor :
not tried, will post once after trying it.

Cons :
No headphone
Yellow shade in camera view (in dim and dark area focus)
