Turn down the page, find "do not disturb mode" and open it directly.

4. Then, in the "Do Not Disturb Mode Settings" page, select the "Always" option under "Silent Mode".

5. In this way, no matter under what circumstances strange calls come in, there will be no incoming call reminder interface, which is completely in silent mode.
