For me it’s having to make an emergency call and the person on the other end either just won’t listen properly, ignore me, not understand me, act in a weird way, or the call has technical problems like there is no reception where I am and I have to run around forever to find signal or a different phone.
I have no idea where that comes from, I’ve never even made an emergency call.
Looking at your comments here, I can see why that was happening to you on reddit.
