I have an s10e and saw an option to "mute all calls, alerts, and media, except for your selected exceptiins" in Settings> Notifications> Do Not Disturb. But I just received a call (my phone rang) from a number I do not recognize which is obviously not saved to my contacts. I mainly did this to mute the multiple spam calls I get daily. Just wondering why this call wasnt muted. Any ideas/tips?
