Samsung Galaxy J7-is a very weak phone. It’s sound reception is very bad. I also use this phone. It is not ease to use it catches virus very quickly and it damage our phone. It’s design is very thick. It phone has features of smart glow it very bad it reduce battery back up. The files was open vey late. It’s camera is very blur. It quality is very low. It is very high in cost, so I suggested to you that to did not buy Samsung Galaxy J7-6 it is hangable phone. My father think that buy this phone so I suggest him to did not buy this phone.
