Speakerphone not working

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?

I had this problem too and ended up getting a replacement. The 'genius' was reticent to talk about the problem happening with others. They did a reset/restore which didn't clear things up and then pulled a new phone.

Curious bit - the phone was not in retail packaging - its hard to imagine that they have cycled very much reconditioned inventory already. Anyway the replacement seems to work fine although I learned the hard way that when you restore from your PC that any new photos taken are lost in the process.

I really wish Apple would consider a removable memory card.....

Apple never replace hardware with retail stock when it comes to warranty related replacements. They always use brown box stock which is usually just the hardware itself and doesn't include anything else that normally accompanies retail stock. Whether these are new or refurbished products I couldn't say. I don't think it's ever been confirmed officially if they use refurbished items.

well I'm in the UK, on O2 and guess what, same issue, the speakerphone is noise canceling my voice 😟

What the ****, it seems every Apple product I have fails 😟

Same problem. For 2 days now, no one on the other line can hear my voice when I use the speaker phone. Also, when recording video, the volume in some cases is extremely low. Much lower than when I first bought the phone. I can take 3 videos in a row and two of them may be normal volume. I hope Apple recognizes this as big a problem as the antenna fiasco.

I just had my phone replaced. Set up an appt w/a Genius, told him the problem and he said, "This is a hardware problem. We'll replace your phone."

This just happened to me yesterday....all of the sudden the mic used for FaceTime, speakerphone and video recording stopped working (well not completely stopped, but attenuated the signal so badly that you could barely hear it). The mic used for normal calls and voice memos worked fine. I took it to the Apple store and the tried a couple of things (restarting, "hard" restart, restore) and nothing seemed to work....so they replaced it. I wish I could say that this is an isolated incident, but there were 2 other customers there because their iPhone 4 mics were messed up 😟

I have the same problem "and" I went to the apple store and got a replacement. In 2 days, the same speakerphone problem. If the noise cancelling sw is the problem, Apple needs to fix it!! Thus far, the iPhone 4 has been a bust for me and a total embarrassment for Apple. Below is my running list of iPhone 4 issues:

1. Antenna issues. Lucky me, I now "have to" have a case.
2. Proximity sensor. My face mutes and hangs up calls regularly.
3. Speakerphone just not working which means video / memo notes also not working.
4. Acelerometer not working correctly. If you launch a video while the phone is in landscape mode, it will not auto-rotate. You have to stand the phone up in portait mode and then turn back to landscape for the acelerometer to kick in and rotate the video orientation.
5. Touch sensativity when trying to move an app from one page to another on the iPhone. I have found times where once I go into wiggle mode, I am pushing to go to the next screen it simply will not do it. I have to play with it more more than I had to on the 3G or 3GS.

If not for the easy of itunes and mobile me, I would move to another phone. Still the best "integrated game in town". I hope apple corrects all these problems.

I too am having a speaker problem, people can't hear me when i call them and i have to put it on speakerphone just to have a conversation! This is my 2nd iphone 4 so no way can it just be a one off.
It is really starting to p1$$ me off and i think i'm going to ask for my money back and get something else if they can't sort ASAP!

Do you have Skype running in the background (there are reports all over this forum with Skype interfering with the operation of the speaker and the headphones volume)

I didn't have Skype running. The immediately swapped out the phones saying it's a hardware issue they've had "with some of the new iPhones."

Hey guys,

I don't know if this issued has been solved or if anyone has solved it on their own, but for some reason, I believe it is software, people can't hear me when I put them on speaker-phone and also when I try to record a video sound is extremely low.

What I have found out though is that phone calls and audio on video recordings still work when I use them with the Apple headphones/mic that was provided with the iPhone 4. When I make a video recording while wearing the headphones and then removing the headphones and playing the video on the phone's speaker sound comes out loud and clear.

Again I believe this is a software issue does anyone know if Apple is working on this?

A friend had the same problem since purchasing the iPhone 4.

She went to the Apple Store (Opera in Paris) yesterday, Apple has changed its iPhone immediately.
