Help Voice echo without case

dwally89 · Mar 20, 2012

Hi,

I've had a Samsung Galaxy S2 now for a few months and almost every time I place a call (or receive one), the person on the other end of the line complains that they can hear an echo of their own voice. I'm not using a protective case on my phone.

Does anyone know how to fix this problem?

Thanks

I already looked through a few of these threads before posting.
All of them seem to mention that the person is using a protective case on their phone, unlike my situation.

I had the eco problem too but i don t use my silicone case anymore and the problem is gone.It seems you have a faulty mic and the only solution is to replace it.Cheers.

Is it not more of a software problem than a hardware problem?

the internal microphone and speakers are NOT isolated as best they can be. either the isolating material has slipped, allowing voice to echo thru the inside of the phone, crashing into the mic causing echo, or there was never enough isolating material to begin with.

So I can be assured that it's definitely not a software problem? Possibly something to do with noise reduction?

The mic is the problem because it s not implemented corect in to the phone case and transmits vibes to the other mic located at the top of the phone.I'm sorry for my bad english in from Romania.Hope this helps.

Of course it has to do with noise cancellation,if you disable the upper mic via noise cancellation you will won t have the echo.
TO disable the noise cancellation press menu key when you are in an call and then you have a option to disable it.The bad thig is that you have to do this every time you recive or start a call.

Will I get a lot of noise though because of this?

Of course not,you will have a lot of noise only if you are in an noisy environment,look at the older phones they did not have the noise cancellation feature and they where just fine.But i recomand repairing your phone to a GSM service
