Samsung had promied to give a mobile having turbo speed technology and so they launched J2 16 series. It only provides 8 GB ROM which is less as compared to other models available in the market today.Another main problem is its backbody. It is very delicate and easily breakable. I am having J2 and my mobile’s backbody broke 2 times till the date.Also, its processor is also very slow as it is having a quadcore processor, which disables it to operate it fast under wi-fi and other internet connection.The display clearity is also not to the point.Also the camera result is also below average.
