I have this j7 prime from 5 months. It is working very well. It never slow it is running very smoothly it have 3gb of RAM thats helps to run smoother. One of the features of this phone is very impressive it has very good camera quality very good. In outdoor conditions the color reproduction is natural. Its battery backup is also very good. It can last upto one day with heavy uses. So I like this phone at this price point.
