First of all samsung doesnt pay that much attention to the lower end models of it.
It doesny provide any over the air update after maximum of 1-1½half years to their lower end phones .
Coming to software the touchwiz. ui is deprived of latest cleaned and a polished ui.
And the processor is not that strong enough to maintain all the trasitions.
Camera is just okaish that too because of samsungs camera software.
The hardware quality of camera is poor.
The screen quality is good enough as compare to other smartphones but then too it is not good phone.
