Speakerphone not working

Same problem here folks and I just solved it! No need to swap phones etc..

I originally thought it to be a software problem too, very faint audio on my iPhone 4 when using the mic on top of the phone for speaker and video. I too tried compressed air to no avail, so for the heck of it I just stuck the absolute SMALLEST, TINIEST gauge wire ever...I mean like the size of a human hair but more rigid (ideally like a fine strand that would be braided into a copper wire) and while looking through a magnifying glass put it into the mic hole on top of the phone next to the headphone jack and swished it around and - PERFECT audio on speaker and video!!!! To test that it worked, just film a video of yourself speaking and play it back and it should work. I keep the phone in my pocket and the smallest piece of dust or anything microscopic getting stuck in that mic hole will cancel out your incoming audio and make it sound real faint. This problem has been bothering me for months, and on multiple iPhone 4s. From the looks of your posts, it is common so skip the trip into apple for a refurb fru phone and use the smallest gauge strand that you can find and you will be all set. Your welcome!

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.

My name is Farhan.. My speaker phone is also not working and i purchased from Saudi Arabia now returned back to Pakistan. Now again i am looking for someone to return it back in Saudi Arabia from the vendors. Its shocking that its speakers does not work

Not all have the options to use compressed air repair tactics.. The phone speakers should have been working perfectly... Which is not in my case as well...

To Lostmymind and others:

The reason your voice isn't getting picked up for speakerphone and videos is because those features employ a different microphone than the one being used in voice calls. The mic giving u the problem is on the top of the phone near the headset jack (microscopic) it's clogged see my above method to clear it(not compressed air it just jams the debribin farther). I successfully fixed mine several times, along with many other iPhones, it was driving me crazy! Guaranteed to work...

Tom078, right on the money. Unclogged the mic at the top of my wife's phone using your method and presto....calls with speaker turned on, crystal clear again. Thank you. Saved me a 2 hr round trip to the nearest apple store.

Tom, i had the same problem, and voila! perfect working microphone after using a tiny wire to clear out top mic hole. thanx again. i'm surprised the aftermarket case makers haven't put a cap or something to cover the headphone jack and mic when not in use. many people, myself included put their phones in their pockets occasionally, and they're a magnet for dust. trouble is, now that i've pushed whatever was blocking the mic into the phone, how long will it be before it rears its ugly head again. my wife and I love facetiming our grandkids, and we've actually used a landline for audio while facetiming. not anymore!

That fix worked perfectly for me too, I had 100% zero sound before the fix, found a very small fine pin and picked away at the grime in the tiny hole next to the headphone jack, then used a hoover to suck away anything left, if you pick at it to loosen it up until it starts to fall apart, but not push it in further you can actually suck it out with a hoover, this gets rid of it for good instead of a temp fix by poking it and pushing itwards. That is certainly the problem though, they have made the hole so small that it easily gets full of gunk.

By the way, if you use a fine pin or piece of wire, dont poke it in really far as you may damage the mike itself, delicate is the word with this one.

Want again to thank Tom078. He was right on the money in terms of cleaning out the microphone to fix the speakerphone issue. I have found that using a 30g needle (the size diabetics use to inject insulin) is a perfect fit. As creak2k says, be delicate--don't jab aggressively.

Tom is a genius, period...!

A HUGE thank you to Tom078!!!! Your idea worked for me too! I have been so frustrated working with Apple support to try to get this problem resolved. Their solution was to restore the phone, which did nothing. I took a small pin and very softly scraped out the debris from the tiny hole next to the headphone jack. My speakerphone, Facetime and video recording all work perfectly now! So simple... why don't the Apple support staff know these kinds of things??? Anyway, I am very grateful that you took the time to share this info on this message board!

Another shout-out to Tom078...this worked like a charm for me as well

Im having the same problem but mine works on speaker phone. If anybody went to an apple store, did they replace it?
