Speakerphone not working

I think I have the same issue as you. Are you referring to the fact that the microphone is not picking up your voice?

Something strange is going on with my phone, normal voice calls and voice recording works OK, but speakerphone audio input as well as recorded sound in videos does not work. It seems to work just barely as I have found out by tapping the phone while recording or on a speakerphone conversation, that noise is captured.

This seems like a software bug to me... I am restoring the phone now. Hopefully I'm not doing something blatantly wrong.

I had this problem when I first bought the 3G. I had to use the restore option on Itunes. It actually took a couple of different tries and a trip to the apple store in between. But the 2nd time I restored it the speaker phone worked fine.

Having the same problem
at first i thought speakerphone was muting my voice but now after some testing it's clear that a little noise is getting through. Seems like the noise cancelling in the 4 is cancelling too much

Hmm .. scary if the iPhone 4 has assessed your voice as "noise" 🙂

I to am having the same problem.

No one can hear me if I try to use the speakerphone yet if I turn the speaker phone off, I am clear to the caller. I also can not capture sound when trying to record video.

Disappointing.

I have the same problem- it works if you call but if you switch to speaker phone, mic does not work. If this is a noise cancellation issue, then all iPhone 4s should have it, right???

I think this is another of Apple's design flaws.
I pray to God that this is a software problem and gets fixed... I hate to go to apple store and try and get a replacement.

Same problem here. Video microphone and calls using speakerphone pick up a VERY faint bit of sound, but nearly inaudible. I have noticed that there's another thread with people having the exact OPPOSITE problem, they can only be heard when they use their speakerphone. This makes it sound like a software problem, rather than a hardware problem, but who knows. Or maybe I'm just holding my phone in the wrong hand, Steve?

I'm in the UK.

Same problem with me on my new iPhone4:

1. When on speakerphone, it would seem my voice is actively cancelled.
2. This happens with the video camera too - unless I shout loudly - and the phone picks me up faintly.

I telephoned O2 customer service, and they are dispatching a replacement phone ASAP.

Same problem here. Using the speaker phone I can hear (sometimes with a lot of distortion, sometimes not) the other person, but they can't hear me, no matter how loud I talk or how near/far I am from the phone. FaceTime is the same story, as far as the other person not being able to hear me. And recorded movies lack sound. That said, I can use Voice Memos, which records my voice without difficult from the same distance at which I'd ordinarily use the speaker phone. Similarly voice command can hear me. I've spoken to the AppleStore where I picked up the phone yesterday, and the best they've offered is to see me sometime tomorrow, when a technician will take a look it. I don't think they believed me when I described the problem - I offered to demonstrate by switching to speaker phone, but they weren't interested.

BTW, I've since spoken with Apple Technical Support and they noted that they could hear distortion of my voice on their end of the call (I was calling using the troubled iPhone 4), but their only suggestion was to blow compressed air into the headphone port. They think that, maybe, some foreign object in the headphone port has convinced the iPhone that headphones are plugged in, when they're not, and, therefore, the when using the speaker phone, etc., the phone is try to get audio from headphones that aren't present. Unfortunately, having no compressed air available, I wasn't able to try that while they were on the phone. (And, of course, that wouldn't seem to explain the distortion of the call that they reported hearing on their end of the call, or why I can use the phone more-or-less normally when I hold it up to my head.) In any case, the only recourse they offered me was to schedule an appointment at my local Apple Store for me, which I'd already done.

Since the appointment isn't until tomorrow, and there's nothing the Apple technical support people can do to expedite handling of such matters, I have to hope that (assuming the compressed air doesn't do the trick) my local Apple store still has replacement units available tomorrow afternoon, which seems hard to believe will be the case.

As suggested by Apple Tech. Suppt., I've now tried the blowing compressed air both across and into the headphone port and the hole for the noise cancelation mic. No effect whatsoever. Air pressures started at pressures well below what I could produce with my lungs, and proceeded up to pressures far above that, using an air compressor we use to clean circuit boards in our networking shop. Tests were conducted after each "blow", so that, if the blowing worked, that determination would be made at the lowest possible air pressure. (Presumably, sufficiently high pressure air could do damage by itself.) All tests failed. The speaker phone, even when I shouted into the mic, never produced any sound at the receiving end.

I contacted Apple Care. They said that it was a hardware issue with my noise canceling microphone. They made an appointment with a local store. I walked in; they swapped out the phone. Everything is working now.

Interesting. It was the 1-800-APL-CARE (1-800-275-2273) number that I called for technical support, so, if that number means anything, I should have been talking to the AppleCare people. Yet, I did not receive anything remotely like the help you received. All I got was the "hit it with compressed air" answer, with an acknowledgement that it was unlikely that a brand new phone already had a mysterious foreign object lodged in its headphone port. When I asked if there was anything they could do to expedite the process at my local Apple Store, I was told that there wasn't. The lady did, however, express the lament (earnestly, I thought) that she could not do more for her callers. Even if I didn't call the correct number, there's no way the staff could fail to know that all iPhone 4s are covered by AppleCare, since none have had time for their initial AppleCare coverage to expire. So why, Apple, are customers with the same problem, talking to the same people, getting such wildly different treatment?
