Major problem of this phone is lagging and getting slow and slow with time and battery given is only 1500 mah which drains fast some times very fast like counting 15 14 13.1% . I can say this the worst battery life I have ever seen. And it is still on android 4.2 jelly bean and I hope can't gonna receive any update from Samsung.
But camera of this smartphone is above average but shutter speed is slow. Gaming is good but you can't download games like asphalt games etc because storage is only 2gb and ram also less it has to be atleast 1gb all I can say that this phone is worst except camera
