I am using this phone since last 1 year but did not suffer any kind of hanging problem. And this phone is best device for gaming lovers. In my family there is four mobiles of Samsung company. The phone has good sound quality, better screen resolution, super amoled display for awesome video clarity. There are lot much things which I love in this mobile phone.and I would like to recommend this brand phones to you not for j7 2016 models but for newer models of this company’s such models like galaxy s8 and c9 pro.
