It is almost defective piece the camera quality is worst front and back. Having 2gb of ram and nice processor it lags much as if the specification provided is false. Internal is 16 GB and gives only 10 GB for usage. Sometimes sd card doesn't get connected and the performance is bad.
My phone fall once and having gorialla glass it got crack inside screen means harder outside delicate inside. I suggest you not to take this device rather take HTC, micromax , yu yureka, and all .
And don't chose Samsung in your lifetime because it will be a wrong decision.
