Phone is basically vibrate mode 24/7 the Emergency Bypass toggle setting on each contact set, allows me to hear notifications for text or call for a select few while not allowing the rest. I’ve yet to see this feature on another phone. Just one of the things why I love iOS.
I just set certain contacts in certain focuses. Basically my dnd nobody can get through with a sound like if I’m at a movie or a funeral or something. But sleep focus and work focus I let my family get though in case of an emergency.
