Hi friends I am sheeraz nawaz khan.llets study about j2 core this is a phone with a shameless battery backup we know that Samsung is an leading brand of India but the phone launched by Samsung is not so good because I am using the phone from last tow monthsbthe battery backup of the phone is very bad I have to charge it many time in a day the clarity of the voice is very bad because the base of the volume is very highthe clarity of the videos is also bad so my opinion is too don't buy it to go because I am using it and I am going to sell it very soon
Thanking you
