Samsung had introduced galaxy J7 as a 4G smart phone in recent year 2015.i am just sharing my personal experiance with this phone.i purchased this phone from the shop.it has some apps which are of no use.and the whole software is not up to mark when compared with price.
camera is good.but the software and battery backup is not according to the price tag.i dont like this phone at all.
even it do not have any automatic brightness feature ( sensor) .
