I have bought lyf wind 7 last year. In this phone 2gb ram and 16gb internal storage and camera is 8mp back and 5mp front.
After 2 months hanging problem and heating so much in use of Internet or game. Camra of this phone is too good sound quality is average and battery also average of this phone.
I suggest you should not buy this phone but you can buy XIAOMI REDMI4A in same price of 6000. This phone support 4G LTE. Phone is based on Android 5.1.1 lollipop.

Camara- In this phone provides 8mp back and 5mp front camara. Camara quality of this phone is very awesome. Front camara is too good.
Battery- In this phone there is 2300MAH
