iPhone 4S mic not always working

i have the same problem, spoke to apple and was told i can have a replacement unit, wait for it.............. in the middle of november !!!!!!!!!!!!

what crap, they will collect my unit in 3 -5 day, then i can wait for any email confirming delivery of the new one.

i can't even keep the old one until a new one is there for me, "sorry can't do that" , just told i will be at the back of the queue.

i told them to just refund me then, p!ss poor customer service this time

It sounds like I am having a similar issue. Siri works great at times.

When its working correctly:

When I speak, the graphic microphone level goes up and down, meaning your voice is being registered.

When its not:

I bring up Siri, the level will stay down. If I yell into the mic, I can get it to register, i will see it go up and down just a bit. It seems that the mic is not being activated in speaker phone mode or something like that. As if it needs the mic "boost" on, and it sometimes doesn't activate.

It is pretty frustrating. I have been able to make calls without any problem so far.

I'm not sure how to fix this when it happens. it just seems to fix itself after a min or two.

I have a similar problem. About 1/3 of my outgoing calls show that they are connected and show a call timer, but I can't hear the other person and they can't hear me.

If they don't have replacements available, I guess I will just wait it out for the supply to catch up rather than be without a phone for a month.

Hi,

I've just purchased the new iPhone 4S 64gb, but have a problem when using the headphones and speaking to someone on the phone.

I have used two different apple headphones, one which came the iPhone 4S and one from my old iPhone 4.

When using the headphones in a call, after 5 mins the line crackles and you cannot hear anything. I have to remove the headphones and use the phone by putting it next to my ear and then it is fine. I have also put the headphones back in to the phone whilst on the call but still experience the same problem.

Just tried out my ear buds today and they clearly aren't going to work. Tried my identical 3G set and the same problem. the female part is not up to spec. If I wiggle it a bit, it works for a second then quits. this is not a good sign. I hope the rest of the phone isn't as poorly constructed.

Well, I was wrong. they work fine but have to be REALLY pushed in. Seems the collar is tight and needs a very FIRM push down to get a full contact. It's working fine now with new and old headsets. Whew!

I am having the same problem half my calls the person on the other end cannot hear me 4s 32 gig black. Boy this is very frustrating bought the phone from apple. My guess is I will be without a phone if i take it to the store for repair. this really stinks. brand new Phone and it does not work its primary function. I thought this was a problem with Sync in my Raptor but no this is not the issue. it sounds like others are having the same problem.

also have mute problems when calling someone but can hear them if I huse hands free speaker.

Same issue here, when I call someone they can't hear me but I can hear them. Have to hangup and call them back, and SOMETIMES it works. Still we shouldn't have to do that. Primary function of the device, and we can not rely on it. Unbelieveable.

After a literally disasterous two days with the iPhone I was able to exchange it today for a black box replacement. Unfortunately the replacement is locked........ Ugh...... I have to go back to Apple again, but at least this phone works right now......

Also, I am curious to who may be using an Otterbox for a cover? Would that interfere with the reception. I'm thinking this may be an issue being mine and my wife's phone have them on.

there's another thread with the same issue now 2 pages long im hoping they find a fix soon as when it happens i cant see its connected to click speaker on off so i look a total idiot to business collegues software fix needed fast and badly for this bug

When I went back to the Apple Store yesterday they hooked the "damaged" phone up to a computer and ran a series of hardware tests. They were able to determine from these tests that the microphone was faulty among other issues. I did not have to plead my case, I did not have to stand there for half an hour waiting for the phone to malfunction.

Funny enough that they replaced my unlocked unit with a locked one. I called Apple Care Support and my case was brought to a third tier specialist who is currently in the process of adding my current phones serial number to the unlocked database. She said she would call me back sometime yesterday. Well, that did not happen and the phone is still locked. But I KNOW Apple will make good on this.

If you are experiencing the microphone/speakerphone issue I would have to recommend that you make a Genius appointment. If your phone is unlocked and you will need a replacement make sure you are vocal about that fact. And make sure you do not walk out of the Apple Store with a locked phone. You can determine this by testing another carriers micro-sim or you can simply plug your new iphone into any mac in the store and go through the visual prompts on the phone until you reach the one that displays the plug into iTunes icons. At which point you should see displayed in iTunes "Congratulations, your iPhone has been unlocked".

I'm having a similar issue: During most of my calls, the caller can't hear me, but I can hear them fine.

SIRI works fine, so the mic isn't broken, but something with the software or att carrier is messing up.

Well I set up an appointment with my not so local Apple store for Monday, both mine and my wife's phone. I know they know about this issue, and I just want a good working phone. I really love this phone and it's features.
