I used Samsung j7 for about 6 month. I liked this phone. I like the ui which is Android N and Samsung has its default launcher which probably good now a days. Samsung mobiles were famous for lagging but in terms of j7 I haven’t faced any kind of lagging problem while I was using this phone. camera is good. built quality is awesome to hold in hand. the grip was amazing. overall good phone in compare to price and other Samsung phone.
