I want to be able to only allow text messages and calls from people in my contact list. This means I don't want notifications or calls whatsoever from anyone else. And I don't want to even know they called or texted when I check my phones history. Is this possible? I don't mind paying for an app that does this but I have heard that there is a way to do this using Android itself. Any idea? I am using a S21 ULTRA
