Galaxy j2 is the very bad phone the firat reasone is its a samsung product
because from 2015/16 samsungs company profit graph is geting down and down
its servicing centers are not working well they demanding lots of money for repairing your mobile also they wants more time like two to three months its very frusteting
most of the time when you use this galaxy j2 mobile its hanggingg lot
and switch off automaticaly its charger also very slow if you want your mobile fully charge then plug it for 7/8 hours
and resolution and sound and call connection are not good internal memory is very low thats why you dont install lots of app in your mobile please dont buy it
