Samsung galaxy j7 is good performance phone its camera is also good its battery is also impressive display is also quite ok but its price is high and the phone really lack of sensors it dont have the simple light sensor which you can get in half price phone and also fingerprint sensor ir sensor and georoscope sensor are also not in this phone so if you really do need these sensors so please dont buy this phone
Otherwise camera and display battery quality call quality is good samsung service is also good but its price is also high and it has lack of sensors.
