According to https://android.gadgethacks.com/how-to/test-your-samsung-phone-by-using-secret-code-0-0162420/:

Accessing the Secret Diagnostic Menu

Before we begin, it's important to note that this feature may not be available on your device. Certain carriers, most notably Verizon and Sprint, have been known to block the code-based diagnostic mode on their Samsung smartphones and tablets, though newer phones from Sprint like the Galaxy S6 seem to have this functionality restored.

To get the ball rolling, simply open your Samsung's phone app. From there, enter *#0*# using the dial pad, and the phone will immediately go into its secret diagnostic mode. Note that the process is automatic, so there's no need to tap on the green call button to enter the command. So if you enter the code and nothing happens, the feature is disabled on your device.

Maybe a Verizon agent can check and confirm whether the Verizon version of the Samsung phone(s) have this feature disabled or not?

I have a Samsung galaxy s9 smg930v and want to use this to test the upper mic to see if its damaged. IT repeats everything callers say back to them. Very annoying. Also have a cracked screen so when I change it I want to test the new one.

Thank you for those details on the issue with your mic on calls, Tim20376. Some cellular service issues can affect the audio of calls, so it's best to try recording a voice memo or video from your phone to test the mic is recording audio properly outside the call.
