I have bought samsung galaxy j2 about a year ago, it runs good for 3-4 months but after that it goes hang and sometimes it automatically goes off. camera is average and the battery also not runs more than a day. And the other problem is its default storage is phone memory and cant change to external storage of SD card, By default all comes in phone memory and than we have to move it to external storage which is irritating, otherwise itll show notification "storage out of memory". camera quality is good. But this phone cant be used more than a year because it gets too slow even we reset the phone. overall the perfomance of phone is average. The sound(speaker) qualit is too too bad or slow. cant even talk on video or voice call on whatsapp.
