The battery backup is not more. The phone hang too much. It’s camera is not so good. The mobile hotspot takes too much power of the battery. The RAM is also not bad but the internal space is not so large. After 1 month or 2 months the phone started hanging and for that we formet our phone and lose all data. The system has not given the hidden features. and it is not updating. In other phone like J5 J7 the version is 5.0.1 after updating it increases to 6.0.1 but J2 is not giving the version 5.0.1 to updating.The screen is not bad
