Hey guys yesterday I purchased this phone samsung j7 prime 16 gb model, phone is comes with 3 gb of ram android marshmallow with mediatek chipset its sound quality was good so when you play the music you will get clear sound and the camera was good but not so good you will get good pictures in day but its camera was stuck in low light, the phone was comes but sleek design and light weight so it looks goods when you holds it in your hands it think the phone comes with good value of money I advice all of you to buy this mobile if you are thinking about it
