I have a Samsung S23 which is a supported device. it's on Android 14 and ONE UI version 6.1.
when I try to merge a three way call only one person can hear hear me.
to merge the call I am dialing the first number letting it connect then tapping merge call and selecting a contact from my address book. the contact is then added to the call but only one of the numbers can hear me.
how do I resolve this
