Samsung Galaxy J7 comes for Price Rs. 17, 900. It has Operating System of Android OS and v7.0 ( Nougat) . It has Octa core processor. It has RAM of 4 GB and Internal Memory of 32 GB. It has Rear Camera of 13 MP with Auto Focus and LED Flash. Front Camera of 13 MP. It has non removable Li-ion 3300 mAh battery. There is no Biometric Unlocker such as Fingerprint Sensor, Iris Scanner. In my opinion, design of this phone is too common. I have noticed that phone slows down during normal usage. However it is bit pricey. There are better alternatives in the market.
