iPhone 4s, echo when using apple headset during a call

Problem happens with our without the use of the headset.

Me and wife just exchange our iphone 4s yesterday to a different 4s. she experience the same problem today with her phone. definitely not a hardware issue. Apple should atleast acknowledge the issue. and reassure all the 4s user that fix is coming. maybe majority of 4s owners will not go back to the store and return and say that the phone is deffective.

Its just gonna get more expensive for apple, but i just want a reliable working phone.

The same thing here. But when I use my old blackberry's headphone, no such a problem. One can easily get one OEM headphone on amazon for $1. Iphone4 has the antenna problem, now iphone4s has the echo problem. Apple is really not good at making phones. What are those testing engineers doing there?

Yes, finally some media attention. I know this forum is about the echo issue.. and as it seems to be a sotware issue let me point out a minor one here... My phone is still showing yesterdays' date in the calendar icon TODAY. 🙂

I hope that many other sites such as macrumors, CNET and 9to5mac covers this issue as I belive there are many of us waiting for at least an acknowledgement from Apple that they are woking on a fix. I'm on my 3rd iphone 4S now and hesitant to get replaced yet another time only to find out the same problem...

I'm experiencing the same situation described by others in this thread. I suspect it's a problem with iOS5 and the noise-cancelling feature in the Phone app.

In the cases I've heard it seems like the ambient noise becomes the primary sound in the audio mix. To the point that the caller audio becomes almost inaudible.

If you stay on the call then some sort of feedback happens and the caller starts to hear "echos."

Having written audio processng software, this sounds like it's just a bug in the noise-cancelling software that is using the wrong source signal or something similar.

People please send Apple feedback via the above link. The more of you who do the quicker we can get this addressed by Apple.

I have 2, 64 gb 4s iphones, we share an apple id and thus share music and most apps, we drive around the same community and both use apple earbud/wired head sets.

One phone has no problems. Just doesn't make sense to me

The other phone was replaced by applecare via phone consult which has the same problem. I am going to the applestore to have them run diagnostics.

I have done everything everyone else has, restore from backup, as a new phone, on and off speaker does work but what a serious problem!!!!

everyone, remember to report problem to apple!

I'm in the same boat! Ordered 2 iPhones 4S one has been replaced 3 times and continues to have the same problem while the other one works perfectly!!!!! Not sure what to say... Except hope Apple fixes this problem ASAP!

I am having the same exact issue. annoying!

went to apple store this afteronn,

they will give me another new phone (the 3rd). NOt sure why I want one but since the other phone in our plan/household doesn't have the problem I think maybe it will solve it.

I asked the "genius" if he has heard of the problem and he said no.

he also said that he is asked a few questions on his computer about known issues and this did NOT come up.

Most discouraging.

I noticed the static thread and I think that might be the same problem, only what the person with the problematic phone hears...when the other person hears the echo....this is just a GUESS!

Still waiting for someone to post a solution to the problem

one piece of advice to the apple engineers: use LMS leakage algorithm not the LMS algorithm to cancel the echo. Otherwise, you will get what we have here, i.e., echo occurs as time goes, since the echo canceler has overflowed.

I bet they use LMS algorithm not the Leakage LMS algorithm. As time goes, the canceler starts to overflow and can't function right. When you toggle the speaker, basically you restart the program and the canceler is not overflowed at the beginning.

Why is everyone returning their phones when this seems to be more of a iOS problem? Honestly I do not think this is a hardware issue and the only way to fix this is to contact Apple and describe the issue as detailed as possible and they'll probably release a fix for it in an upcoming iOS version.

So instead of going to the store and returning your phones, contact Apple support and report the issue.

done

Same thing with me, started to get the echo after about 5 minutes into the call with the headset I took off the headset and the echo was still present, I had to end the call it was really bad. I then made a new call without the headset and I had the problem. So now I have an echo on just about every call I make and poor battery performance. GREAT!!
