This device is launched by an Indian company Reliance and believe me it’s performence is better than many samsumg mobile. The sound is good, camera is good, performance is nice, lots of new features are given in this device. It support 4g volt and you get a jio sim with this device, means free internet, free calling, free message for three months.
Now look drawback of this device is that, it hangs sometimes, the battery backup is not up to the mark. But you can not question it because of its lower prize ( 4, 199) . Not other brands will give this much in this cost so, I completely recommend this phone to every citizen who want 4g mobile in less cost.
