The features which the j7 is providing is the most promising mobile I have ever seen. The sound qualitity and also additional head set of 3.5mm jack is producing the high sound qualitity.
The picture contrast of the j7 is much better in comparison to its segments. The phone is also very strong. The bike mode which is provided in this phone is the advanced feature noticed in this segment of mobile.
In my opinion especially for the youngsters I recommended to purchse j7.
