I am a Samsung lover.i used every single phone that samsung releases.
I bought J2 in december 2016.
I thought that it will be a great phone.but no its not at all.
Bad things-
Camera not so good
Ram is not good
Phone is very slow
Hanging to much.
After using it 1 month I sold it and buy iphone7.
If you are a game lover and want a good performance from your smartphone then dont buy thiss. Thank You
