Samsung Galaxy J2 is good samrtphone but not recommend bcz in market avilable other best smartphone.
if talking about Samsung galaxy j2 features so samsung give only 1.5gb ram so I have face very hang issue if I use multiple application at a time.
battery backup is only 2600 mAh power so I need to charge phone twise a day.
camera result is ok 8MP bcz samsung give a good camera.
graphics are same all samsung device nothing to different other samssung device.
if your budget under 8000 to 10000 INR show other smartphone.
