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.
Agreed, this is an excellent top-tier feature. My phone is always on silent, my watch takes notification vibrations instead of it as well so it’s pretty much always silent. The only person who gets the added bonus of my phone making a noise, especially when I’m asleep, is my partner.
