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.
My mom knows exactly what hours I work and yet she calls at random times, often just to say hi or see how I’m doing. She hates texting and exclusively calls. I know she has good intentions but I could never turn this setting on for her, my phone would be ringing in the middle of meetings all the time.
