Unlike a typical Samsung mobile, this is more reliable. The android phones from Samsung are usually boring after 1 year and the battery life decreases, color will start fading, etc.
Samsung J7 is not giving all those problems.
It looks stylish and comfortable to handle. The camera(both front and back) are too good! There are many modes.
The inbuilt apps are also useful. Sometimes, the phone hangs and the touch doesn’t work. But on a whole, it is a good mobile and deserved the price you pay.
