Mysterious "Touch Tone" (DTMF) sound during Note 10 Plus conversations?

[Android Central Question]

I recently purchased a Samsung Galaxy Note 10 Plus for Verizon. Since purchasing this phone, I've noticed that frequently my voice calls will have a sporadic DTMF ("touch tone") sound randomly during the call... I'm usually taking on speaker phone with the phone sitting on my desk so I had assumed the other party was simply leaning their chin up against their numeric dialing keypad and accidentally generating the tone...but it happens in quite a few calls and I discovered the other party I was taking to was also taking on speaker phone so neither of us was touching our phone keypads.

Anyone know what the problem is/ how to eliminate the problem?

Googling, I find quite a few complaints of this issue with various carriers and various models of Samsung Note.

Prior to Note 10 Plus, I had Note 5 and Note 2 (Verizon for all) and did not experience this problem.

Thus far, I've found quite a bit of disappointment with Note 10 and it may be the last Samsung phone I purchase. I'm hoping there is a simple way to eliminate this annoyance.

Thank you for any solutions/ideas.

Happy holidays to all,
CR

Can try clearing data,cache,and force stop the phone app and to do that long press phone app icon tap info then scroll to storage , if that doesn't work try in safe mode making calls see if still happening.'ll leave a Link to register so you can communicate here as a guest account you can only post questions but can't reply.https://forums.androidcentral.com/showthread.php?t=409154

Welcome to Android Central! When this happens, and you're on speakerphone, is the screen open to the dialer? If so, do you have a screen protector on? That can sometimes lead to phantom touches, so I'd try taking the screen protector off.

Also, are you certain that you're hearing touchtone tones, not very rapidly-dialed DTMF tones (those are tones produced by the phone system to route calls, and your carrier may have a problem that allows you to hear some of them sometimes). If they seem to be dialed too fast for a person to be dialing them, that's probably what they are.
