I usually do this every night when I’m about to sleep, and also during times when I want to decompress from the barrage of notifications. Sure, DND mode is a thing but I really enjoy the feeling of being unreachable sometimes. Having it on DND still makes you receive the notifications. It’s also easier than turning your phone on and off. Regarding emergencies, I really don’t have any situations where it’d be so pressing for me to react immediately to something. And either way I’d never sleep having volume/vibration enabled from calls.
Is there anyone that relates to this?
Similar here. My DND runs automatically between 10pm and 7am, but I have a small number of people whitelisted whose calls will come through. Mine also has a setting where it will let someone through if they call twice within fifteen minutes. I don’t think anyone’s ever actually phoned during that time block but it gives me peace of mind to know I can still be reached in an emergency.
