I purchase this Samsung galaxy j4 4 month ago. Very easy to use and design is good so easy to carry. screen quality is also good and better sound quality but, the performance of the phone is very very poor initially it works fine but after 2 month it start hanging and shows forced to shut down application. And sometimes it reboots unnecessary. Don't know the reason but it sucks I always keep internal memory as minimum as possible but still face the same problem. Either it has good battery backup but very poor performance.
