This is very good phone of samsung under rupees 16000, it comes with 5.5 full hd display , and 13 mp rear camera and 5 mp front facing camera with led flesh light, 2gb ram and mn li-ion 3300mah battery.
This phone works on the android os, v6.0.1 marshmallow plateform
It's cpu is octacore1.6 GHz cortex a53 which is much better in this price.
It comes with accelerometer and proximity sensors , display of this is super amoled capacitive touchscreen, with 16M colour.
In my openion this is much better smartphone of this price segment.
All the best !
