Hi lately I've been getting that "Unfortunately Phone Has Stopped" message, usually when I finish making a call and then go to make another call. I am using the latest version of Marshmallow 6.0, I checked I am updated on my everything. I should mention that I do use wifi calling since that is the default when I am on my home wifi network. And when I switch back to 4G LTE I don't have the problem, but I shouldn't have to do that everytime I want to make a phone call. SO can anyone help me?
