I have seen this on many phones but never had a problem of it for myself. So maybe someone can help me:
Callers are saying they hear themselves echoing when they speak to me. If I turn on "Clear Sound" it muffles it but they still hear it. Does anyone know how to fix this?
My carrier is Verizon and others that I know with the phone have the same issue. It is important to note, the people I personally tested it with, have an S4.
**It is important to note that I do not have a case on the phone. My mics are all clear of dust or anything else. And this is not a slight echo. It is a LOUD AND CLEAR echo. But my voice is fine and I do not hear an echo.
