iPhone 4s mic issues

I am also having this problem. went to store did a few restores but still having issue. The proximity sensor interefering with the mic seems to be accurate for me. I am also getting a random echo. 16gb 4s at&t.

hardware problem - iPhone 4S 64gb White

I have received a replacement iPhone today.

But I am still having the same hardware problem, when using the headphones in a call - I cannot hear the other person and the other person cannot hear me.

I have to put the phone on loudspeaker and then switch it back to the headphones, this then works for couple of minutes and then I'm again faced with the same problem.

Since Ive had the replacement I have made 20-30 calls and have had an issue with every call which i've made using the headphones.

Firstly, I was given a refurbished iPhone even though the my original iPhone was within 14 days of Purchase.

I would like for someone to get in contact with me and resolve the issue I am having as this phone is absolutely useless.

Same problem! no matter who you call or who calls you it randomly cuts out and ur for ever yelling the the iphone 4s saying 'can you hear me!!' i have found that if im laying down and got the fone under my head or resting it on my ear there it happens more requently :S

also anyone having probelms with reception? i get calls cutting out when i have full reseption and i cant call back for minuites because the fone is searching and then says SOS ONLY :S never happened to me and expesally since im with telstra

The restore did not work. Turning off siri and bt did not work. Still experiencing about 30% of my calls having the strange echo and no voice transmission. I am getting new hardware in a few days. It seems like the lucky number is 3 iPhones to get this bug fixed.

I am also just begining to have issues connecting to the AT&T network whereas when I first got the phone things seemed fine. Full service throughout my apartment, the signal never degrades, but the phone just wont connect to the network.

Went to the Genius Bar and after testing they could not reproduce my problem, but they replaced the phone as it was "new". The new phone seems to be Ok, but I am not wild about the call quality, hoping it is just due to where I am calling from. I have not really had enough time to test it sufficiently. But I must say the Apple staff were very helpful and cooperative.

My Mic is not working at all on a iPhone 4S 64GB Black. Works fine on speaker mode. Tried Restore, DFU restore, so only option left is replacement! Have found a lot of posts about this issue. Keep the faith folks- this is my first problem after 9 iPhones!

I’m having the same problem with my 4s iphone. I took it back to Sprint, but they told me to go to the Apple store. First I thought it was the earphone till Apple told me that it could be the mic and they gave me a new phone. Problem is I’m experiencing the same thing with my new 4s phone. After 30 minutes of using the earphone there's a cracking sound.

If the problem isn't a constant one, and people can hear you sometimes, it seems like if you turn the vibrate off on every function that it fixes the problem. Really strange, but it has worked so far.

I have this problem too! It's only started happening recently. My iPhone 4S was working fine and then it started to happen. What I have noticed though is that it only happens when calling other iPhone's, has anyone else noticed that? I can talk to other people using Blackberry or Nokia etc and they can hear me fine but as soon as a call is made to an iPhone or received from an iPhone, it starts the microphone muting issue again! They say they can hear me occasionally, a bit like a broken signal connection but then it goes mute. Is it just an iPhone to iPhone issue? Has anyone else noticed that?

Brand new Iphone 4s 32g black. I had the same problem, MIC not working on outgoing calls. I removed the SIM card and re-inserted, and now it works! I've tested and retested and I could not replicate the issue. Before the issue happened on every outgoing calls.

Got my new iphone 4s yesterday from apple store online in Norway. Mic was not working right away after setup and restore from iphone 4 backup. I can't seem to do anythin about it. Sometimes the microphone works (for Skype, Magickack, Voice memo records) and sometimes it just doesnt. Well, acutally form listening to the voice memo records i can tell that the microphone 'works' but there is a lot of white noise and i can here my voice only very quite in the background.

Outgoing calls work with the headset and when I activate the speaker.

Again, the funny thing is that the microphone seems to turn itself on and off (mute) at random, even if I don't do anything...

My frustation is that tomorrow Im going for business tryp and my New Iphone 4s is not working properly ;-(.

I hope when I come back to Norway the apple store online change my iPhone 4s for one who works.

Same problem after upgrade to iOS5.01 today. My new white 32G 4S loses its microphone intermittently. This needs an Apple fix and pronto.

I see an obvious bug: when I tap the mic mute icon while making a call, it doesn't turn blue.

The temp fix seems to be this --

* tap the speaker icon

* tap the mic mute icon

-- see both in blue state.

* tap speaker icon again to turn it off

* tap mute icon to turn it off

-- microphone now works -- for the current call only!

I'm haing same problem...people either can't hear me, say my voice is very distorted or ask where I am because they can hear the rain [when it's sunny]

I bought 4iPhone 4s, this one with audio problem, 2 with batteries goinf flat within hours [Apple replaced one and fixed the other].

So I suppose if we are getting only a 25% success rate, Apple should do better than making me waait 3 days to meet at the Genius bar.

Suggestions for something better than iPhone 4 are welcome

I am from NZ and face the exact same problem. It work fine for the first 24 hours (Siri not calling) and when I received my first call it just muted. I hope apple replaces it, it brand spanking new...

I am also seeing this issue.

I should have used the phone on the iphone store before bringing it home. Now I have to take it back and get it replaced.

Reading the board I don't think the software reinstall is even worth the effort.
