Well said jseaver. I am still having the problem, and going into week 3 of working from home here in CA, I am relying on the phone function more than ever. I have a regular iPhone 11, no pro or anything. And like most I’ve seen here the echo is heard by people at the other end, not me. As if the mic is not muting when someone at the other end is speaking, and they are hearing their voice coming out of the speaker bounce back through the mic. Too bad that it seems that the phone function of smartphones these days is secondary to their function as streaming and texting devices or cameras.
I am on conference calls several times a day and have had to resort to using my earbuds. Not my preference, but it works.
