Helo my dear frienda. Today I am share my personal opanion about Samsung Galaxy J7 Prime. I am using Galaxy j7 before three month.j7 is a good set. Its sound is normal.neither more nor less. Its styal and design is also good but when we talk about its other feature like its battery backup, Ram Rom and andriod virison so it is nothing. According to other set like oppo A37. My friend use this oppo A37 it is good shape bettery bacup is good all other feature is good according to j7. J7 look is not best. So friend don’t waste your money for purchase this set.
