My mom uses a j7 gold and its awesome.although it has some draw backs and similary advantages too.like ultra power saving mode which is absolutely awesome and its camera quality is pretty impressive.the disadvantages are its quite similar to any other samsung models and doesnt have many accessibilities like change of font and etc but I would say for the money we put it is quite good and the head set that are packed with samsung j7 are not quite good they are not like any other headsets of samsung they are so plane.and yes j7 take much less time to charge which is an awesome thing.personally if u ask me I would suggest to buy this phone.
