I have been using j7 prime a 32 gb varient from last 2 months till now it has no major problem. Well, coming to the darker side the only thing that matters me the most is after it is connected to WiFi it sometimes hangs a little bit, but its perfectly okay! Not a big issue, And on the brighter side I would like to point its great features like its sound reception and its speaker, it is loud and clear with no noise! . It has a great lustrous design with a curve style on its edges. Its multi window feature is very comfortable and the phone never heats up even if it is used for a long time.Its value for money basically!
