Sure it's some software glitch that Samsung should get rid of quick with an device update. First thought my new S22Ultra has broken speakers but thankfully that's not the case.
Please refer the below:
There are many similar issues; please investigate and provide a quick solution.
I have the same issue - i turn off wifi, and it works normally - but it is a very obtrusive noise, and its so bad I dont want the phone anywhere near my ear. You can hear it on speakerphone as well, but not if I have bluetooth headset connected.
Please make sure that your device is updated to the last software update.
You may try to reset the network settings, from the settings > general > reset > reset network settings. ( CAUTION: This menu deletes all the network information such as Wi-Fi, and Bluetooth).
Kindly try to remove the SIM card from your device for some time, then reinstall it again, after that try to call and dial.
If the issue still exists, you should visit one of the authorized service centers for a further check, and you may refer to the link below:
