If u want a smart phone with all features that would cost around 20k then you must try Redmi Note 3 .
It took me 3 flash sales to buy this but now you can buy directly from any shopping site or mi.com .
About features .I have no words.
.
.
.
It has 16 mp and 5 mp pixel camera.
Although night vision is weak but daylight photos are mind blowing .
You can also take pictures using audio or biometric scanner.
.
It’s processor and graphic card .about it I don’t want to mention because everyone knows how powerful they are in this phone
.
Battery life is very long.
But charging time is also long as it doesn’t support fast charge.
.
High Resolution screen.
Excellent color reproduction.
Large screen.
.
3gb ram and 32 GB ROM.
.
Fast Biometric Scanner.
Chip level Security.
.
Metal Finish. .
And many more in software of OS MIUI
.
It’s is best product under 12k.
