I have my iPhone on Do not Disturb allow only contacts to ring my phone. Also, for each contact I want to be notified about their texts Ive edited each contact > text tone —> Emergency Bypass on and no text tone. My phone is now back to what I feel belongs to me and not scum using MY phone to bother me for their benefit.
