It’s rear camera is 16 mp with LED flasg and front camera is 8 mp. Its camera quality is very good. It’s Android version is 6.0.1 marshmallow. It’s ram is 3 gb so not hanging problem. And its rom is 16 gb it is too low. And its sound quality is good. And many features also in this cell but it’s price is too high.
