Samsung galaxy grand prime packs really low end specifications with such a high price tag. It is just a waste of money.
You can buy devices which performs a lot better than this one.
Since it is a Samsung device, UI is really bad looking and it lags after few months of usage.
Phone gets over heated if you play heavy games for 5 minutes. Applications sometimes take time to open and overall user experience was not smooth.
Camera performance was average nothing that great.
I suggest you to buy some other device in this price range.
