Galaxy S0 FE 5G continuous notification sound

[MilanC]

Newly bought S20 FE 5G buzzing all the time with notification sound while no new notification is observed in drop down.

No new messages, mails or app notifications yet the sound keeps buzzing. 

Things tried already: 

1. Accessibility>>Notification Reminder >>Turned off

2. Notification silenced by going to specific apps 

The notification sound also comes during phone calls.

Have tried putting the notification sound as "silent". This stops all types of notifications which I don't want. The moment I choose a notification sound instead of choosing silence, the same thing repeats. It's just non stop.

Any solution this would be really great.

Install Good lock and then install Nice catch module. You will come to know which app is causing the nuisance.

Turn vibration history on. Also don't turn off notification vibration. Because this module can't catch what is causing sound, but it can catch vibration. Then check the history.

Try nice catch

Or
Once perform reset normal settings

Settings>general management>select reset>click on reset settings
