I have read the comments and I am having the same problem as many other people in this conversation blog. People calling me on my S20 FE have an echo on their end when they call me. It is repeating everything they say and it only happens when they call me. It is everybody. But, when I call them, there is no echo. It happens in area code 32526 and possibly others. It just started a few weeks ago but is very significant because conversations cannot occur. I thought it might be associated with my Galaxy watch but it occurs even when it is off. I also restarted my phone. Any other suggestions?
