Why why why can't samsung fix the problem with the galaxy j3 prime restarting!!! It's been over 5 months that it's been crashing. I've factory reset my phone 2 days ago and it hasn't worked at ALL. if someone can help, please tell me what to do, weather its waiting for an update or doing something in settings.
you restoring your settings? because that could be the issue. try just restoring contacts maybe messages calendar pictures and just do not restore your settings and just manually set it up. because I had a similar issue with my s9 and I did a factory reset and I did not restore the settings and the issue seems to have been solved for me.
