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.
This has been on Android for many years.
Been on iOS for 7 years.. iOS 10
