J7 Prime has worst camera among all the j series . Even my previous 5 MP sony hansets camera is much much better. Photo has no clarity. And system error also exists like suddenly android.com has stopped or facebook is not responding. I purchased j7 prime a week ago based on features but truly disappointed. Willing to sell it right away and purchase another but never samsung again. Even network signal strength is so low. while my friends with same service provider and same network uses swiftly I always have to search for network and regiater to use internet services
