Samsung galaxy J7 prime is the best in all samsung J7 series. Beacuse this phone’s size is mediam. Not too big and not too small. And its ram is 3 GB. That is not hangable. And the J series not so hang as per my view. It’s 4G LTE phone too with dual sim. That is sim 2 holder and memory card holder is one. But I dont need memory card beacuse its internal is 32 GB. And it has 13 mp camera with auto focus. And front camera with sweet selfie. It has finger print lock on home button. And work good. We can upgrade its verson to oreo( 8) . One little problem this phone hasn’t slim body.
