I just switched back to TMO from ATT. While going through all the transfer stuff I noticed that the S20 FE does not offer the "Knock Knock" notification sound that I used on my ATT S9.
1. Are notification sounds carrier specific or device specific?
2. Is their a way to import the knock sound while I still have the ATT S9?
3. Or is there an App with custom sounds?

You can download just about any sound file and use it as a notification sound. I downloaded a submarine dive Klaxon sound file from Wikipedia and use it as a ring tone for the alarm monitoring service.
