Why do callers hear an echo during phone calls?

i have the galaxy3 and it was doing the same thing!! Drove everyone insane but me because i didn't hear anything! I went into call history log, hit menu, went to call settings, additional settings, and unclicked the Noise Reduction selection and it fixed the issue. hope this helps!

"Hi Wendy

I have the same problem.

It seems to be some clever trick that Samsung have included to try and reduce ambient noise on incoming calls, and have basically made it so that on incoming calls the speaker is on very quietly, which makes a loop and causes an echo for the caller.

When you have answered the call, if you press the menu button, and press ""noise reduction off"" if will fix the echo problem for that call. unfortunately i haven't figured out a way to turn it off permanently yet!

"I finnaly found that the problem became from the extra shell case i used.

so avoid any extra shell case to make a test.

That's the solution a found whith mine. I think that the extra case (not a samsumg case) genarate echo because of the 2 microphones on the top and the bottom, I don't know why but I think that the case act like a echo box."

"if it is in a protective case take it out mine works fine after this.

it is very annoying when it does echo"

"something you can try.

1) make sure the carrier have the hardware you're using is registered to you and not your old phone.

2) use a headset w/ mic and make a call to see if there's an echo.

-if this is yes, it could be your carrier tower OR your hardware

- if no, then it's your hardware.

3) use a speaker phone and see if there's an echo.

-if this is yes, it could be your carrier tower OR your hardware

- if no, then it's your hardware.

if the problem still keep up, or been fixed, let us know! ^_^"

"This is a problem with most phones. Just pick any manufacturer and type their name in google and then put ""echo problem"" after it, without the quotes. You will see tons of phones have the same problem.

The problem is they use the phone case as a type of speaker box. They allow the back of the speaker to ""breath"" into the case so that it can produce bass. That makes the speaker sound better and easier to understand people talking.

If you have a noise cancellation mic at the top of the phone, you can usually put a piece of tape over it and that will help.

A better fix is to take the screws out of the back of the phone (if you are brave) and putt something like a piece of closed-cell foam near the bottom of the phone where the regular mic is. The idea is to keep the sound from the speaker from traveling into the regular mic. If you put the foam too close to the speaker, the callers will be a little hard to understand because their voice will have no bass and it will make the phone sound really cheap.

But it is a lot easier to put the tape over the top microphone. ;-)"
