Both my husband and I have an iphone 11. He is one that always uses the speakerphone. Every time I call him, I hear myself talking when he has his speakerphone turned on. Same thing happens if he calls me. Our phone cases do not cover any of the openings at the bottom. This is becoming very frustrating as we are having to work from home and headsets do not fit properly. Speakerphone is the easiest for us to use, but so annoying when the person calling has to hear themselves "repeating" everything through the echo.
