When samsung galaxy j series launched I was exicited to buy a phone of this series.But when I bought samsung galaxy j3 then after few weeks this mobile started to be hang.and day by day it hangs a lot. when I contact to service center then they respond that it was happen due to downloading lots of aaps in your mobile.
But when I uninstall apps then also my mobile was hanging.then I changed my mobile.This is worst mobile I ever bought.so I adviced to all that please dont bought this mobile or any mobile of j series because this series hang a lot!
