I'm in two minds about whether I should get a new phone. The one I have right now (from the Samsung A range) has been randomly restarting, and my sister who has the same phone, has had that happen to her. I don't want to get rid of the phone until it's on its last leg, but maybe it's time for a factory reset.
True. I found a setting in my phone turned on that allowed the phone to auto-restart when performance isn't optimal, but it was only supposed to restart when the phone wasn't being used. Maybe it's time to replace this one.
