I bought samsung galaxy j3 last year online when itvwas released. I thaught that it it would be good but it was not the phone which I expected for .it has 4g connection and has a good camera quality but others features are not so good.its battery pickup is not so good cannot use it even for 4 hours .it has 1 gb ram and works on android version 5.0 and above, but not a good mobile for playing games and also cannot install apps , it lags a lot whemile installing apps and while running them and somtimes gets switch off .its internal storage is 8 gb which is not sufficient .it is not good enough compars to other samsung j series
