I m usnig samsung galaxy j7 nxt from the six month.i m telling you its is awsum .samsung company give us a 2 gb ram for this but it is enough for us as well as for this phone also.In my opinion 2 gb ram is enough for this phone as compare to the other mobile phone.Any program or any task u proformed very well with this given ram and there is new android version named is naught 7.0 .if u want to perform multi tast in single given window .You can easily perform the multi task with this phone.accroding to me this phone is too good n compatible.but I suggest all of you, I think you have to try once in new era. Thank you
