My phone is on do not disturb 24/7. I do miss some calls occasionally, but in general its been a big improvement. Been doing it for the past 8+ years. The phone is there for me, I'm not there for the phone.
You can have it on DnD and still allow calls though. I have the same on iPhone but 1 contact (my wife)is whitelisted and I always get notifications from her and _all_ calls go through because I never know from which number they call from the bank or school
