Hi @tamcat ,
Have you checked all the settings for the Do Not Disturb feature to ensure that they are what ''you'' want?
To turn off some or all sounds, swipe the status bar down with two fingers and tap ''Do not disturb''. Check what the settings are in these options:
''Total silence'': Turn off all sounds and alarms. Override sound settings from other apps. Set how long to stay in this mode, or choose indefinitely.
'' Alarms only'': Set how long you want to only hear alarms, or choose indefinitely. Tap ''More Settings'' to customize which other interruptions to receive.
''Priority only'': Set how long you want to only hear priority interruptions, or choose indefinitely. Tap ''More Settings'' to customize which interruptions to receive.
To create an exception for repeat callers that allows a call from the same person within a 15 minute period, tap ''More Settings > Priority only allows > Repeat callers''.
