I am Sharing my experience and some facts of k4 note
As you know that it comes with a fingerprint scanner which is good but it supports only 2 fingers which is disappointed. Coolpad note3, letv 1s supports 5 fingers.
it has 1.3 octa core 64 bit chipset but it is hanging and legging while playing high and games. If you like to play high end games then it is not a best choice.
it's 5MP front camara is very good in price of 11000 but 13MP main camara is avrege would be better.
5.5 inch full hd screen is great but I find it is a bit yellow
VR Theator mask wroth ?1300 is a best option for watching movie videos youtube if you buy it with k4 note you will pay only ?500. Which is good deal on amazon.
Dual dolbay atom speaker are best in class for sound quality
Overroll a 5.5 inch 3gb RAM 16gb ROM 3500 mah battory fp scenner Vibe ui nice design is good in price of ?11000
So I recommed it
If you have any problem suggestion question advice then plz comment in disscription
Thanks for read
I hope my review is helpfull for you.
