I am using J2 for 1 year. In my opinion it’s not a good phone. Battery life is too bad. Main problem is the ram and internal memory. 4 gb of 8 gb internal memory is full of preloaded app . Design is good. It’s sometimes get stuck. But this phone is easy to use for a new smartphone user. In this price range anyone can get a 100 times better phone than J2 . And a cons. is that J2 doesn’t get marshmallow.
