I had this galaxy J3 almost a year now. I love it. Performance and display is awesome. I did not encounter any major problems . The only thing I did’t like much is the camera. It still gives descent photos but it comes out blurry sometimes but overall this phone is great. Am not using an sd card and I only have the 8 GB internal so I just keep important apps and 2 games installed. but sometime it have a hamging problem, this is a nice phone under Rs.8000
