Random vibration

[Easy34]

My Samsung S21 Ultra is randomly vibrating for some reason, and I've downloaded Nice Catch it seems that phone calls are causing it, but I have no idea how to stop it

And it pauses my videos each time it vibrates, please I need help to fix it

put the device in safe mode and than after 30 minutes reboot

I have turned on the safe mode and turn it off back  after almost an hour and it's still doing the same thing after rebooting the phone

Same! Finally someone with the same issue. I also downloaded nice catch and it was the Phone app. I called my carriers like crazy to check if those are just missed calls that Phone app didn't register for some reason.

I'm going to write to Members to see if they have anything to provide.
