Samsung galaxy j2 isn’t good phone I will never buy this The first problems or disadvantages is the heating issues with the device. Now I believe it has nothing to do with the processor because the heating problem is experienced while charging the device even if you don’t use. It is not like insane over heating issues but why it should heat at all when it is just charging the battery.Next Galaxy J2 2016 issues or cons is that it does not support USB OTG cable. I want to suggest you please don’t buy this phone
