How to do it

1. 01

   Open Settings > Apps > Phone.

2. 02

   Turn on Unknown Callers. If the row says Silence Unknown Callers, that is the same switch.

3. 03

   Call yourself from a number that is not a contact, if you want to see it go to voicemail.

People in your contacts, and numbers you have recently dialed, still ring. A school, a clinic, or a delivery driver will not, unless you add them.

Turn it off on a day you are expecting a call from a number you have not saved. The recent-calls list still shows what you missed.
