I have used a Samsung galaxy grand prime. It’s is really bad mobile. It’s performance is not good. Just 1.2 Ghz quad core professor is used in this phone. Working speed is very slow and buffering. Some time it is hanging too much. Worst in performance. Sound reception is bad. Low sound and there is no quality in sound. Body design and style is good. It’s looks beautiful. Camera quality is also low just 8mp. And there is no good features in this phone. Features are less. Price is high when compare to other brands at same features and specifications. With this phone value for money is less. But it is easy to handle some what good. It is user friendly. Simply waste of money.
