The Galaxy Note 5 had block phrases but the note 20 doesn't.
Please put it back
I want to block creeps telling me they want my house. Message always starts with I'm looking at your house
I want to block email to sms mms from Hotmail Gmail etc.
Also you should default share read status to off so these creeps don't know its an active number. It's irresponsible to turn it on without notifying the user.
