iPhone microphone not working

GOT same problem, my own fault i think

I dropped my phone on a slice of bread it got covered with butter, 😊 now my microphone not working, tried blowing with hairdryer sucking and blowing into speaker, but no can hear me, i tried to record via voicemail and i can hear myself very faint, any idea how to unblock?

works on earphone speaker fine.

same problem here as well

Microphone deosn't work with phone calls, unless speakerphone is activated

Microphone doesn't work in Voice memo at all

However, the microphone will pick the slightest noise while recording a video.

things i have done to try and troubleshoot that didin't alleviate the problem:

1. hard reset
2. update IOS

3. Restore and set up as new iphone

4, DFU Mode and Restore

5. Unplug and replug headphones numerous times.

My SWAG: it is software problem on refurbushed phones that are not QC/QT at refurbushment.

Just becuase the decibel needle in voice memo moves when you tap the screen, doesn't mean the microphone actually works.

My Solution; returning to Apple for a replacement. it like Applecare is more than going to pay for itself. Since no Apple store is within 250 miles, I have to wait on shipping.

Just bought iphone4 3 days ago and couldnt use yet cause nobody could hear me since my first call. When i call i hear them clear and also my voice very weak on the back. Tried the voice memo and cuoldnt hear my recording too. Change the simcard to another iphone and it works well. Already restared as asked and nothing happens. Wondering if it,s a software configuration problem or it s simply came damaged from factory. ..

This seemed to happen to me twice right after my Iphone 4 went into temperature mode. And oddly enough I have been in the Sun many times in the past few months and the "temperature mode" just began to happen a few weeks ago. Am going to meet with Genius tomorrow.

Restoring from DFU mode as a new iPhone solved my problem. It's been a week now with no problems. If it is a hardware problem, I'm guessing it will return eventually but I'm hopeful.

Same problem here. Mic hasn't been working well for about a month on and off.

Mic will work after a sync and then shortly after NFG. My carrier is Bell and I'm on a "3 yr.contract".

iPhone now 3 months "out of warranty" and of course I'm now expected to pay over $200 just to get a

quote and such on what the repair will be. Not a happy Apple or Bell customer right now.

Grrrrrrrrrr..........

I had a co-worker that was having the same problem.

I took off her case, turned it off, and blew it out with some canned air.

Her "Home" button was also not working well. I cleaned that with some LPS.

I found that if you take your rear glass of your phone and push down where the dock assembly connects to the logic board the mic works but as soon as you let go it stops again. Trying to pin point where it is. Can anyone else find this.

I had the same issues have had. I took it to the Apple store near me and they replaced it without any questions asked, apparently this is a common issue

hi Everyone I bought iphone 4S from Espoo finland, from Elisa, and I have problem in listining from other side, I went to coplin but they are not replacing my mobile, I am paying every month 25 euro for the mobile for 2 years, but it seems Finnish people are not active in theri business or do not respect their customer, they just avoid things and sell their electronics what I feel.I am very sad now. they want to send my mobile for repair now after long discussion, hope apple will take some action other wise apple will be also lose like Nokia in future

I have an iPhone 4 that has THE microphone problem, and its a couple months out of warranty. I bought a bluetooth headset and guess what, SAME problem. Sometimes it works for about 15 seconds, then stops. This seemed to start after iOS 5.0.1. So what do I do?

This is a bit of a response to anyone interested as you guys seem to have so much trouble. I have 2 iPhone 4s. One works, one doesnt. In the time I've taken to PAINSTAKINGLY take these apart and piece them back together more than 40 times, I can say this:

1. The microphone "boom" is a small rubber connector on the inside of the phone connected to the dock which inturn is connected to the speaker (this means for speakerphone or any noise from apps you use). For the person who spilled butter on their phone, you've blocked this small canal and need to open it up, unscrew the screw to the right of the bottom speaker and the screw to the left that is on the logic board. This will allow you to (gently for god sakes) remove the speaker and expose the microphone to the right of the dock. Pop the rubber piece out (gently, again) and clean it out. It comes out a bit a like a stopper so don't be scared of it but don't break it, obviously.

2. For those who are experiencing issues like flickering sound, flickering voice or other issues like this, it could be hardware. If you can't narrow it down or don't feel like narrowing it down and would rather take it to apple, TAKE IT TO APPLE. God knows I've broken enough parts for two lifetimes opening this thing up. If I had advice for anyone I would say take it to the Apple store and let them deal with it. Just pay them. It's easier, trust me.

3. 5.0.1 has given people problems out the *** that I can't believe haven't been solved. Anything from completely dropping service for 3-5 days at a time or like vinnie has mentioned, a short in the bluetooth or earpiece jack. I have an iPod 3rd gen and a 4th gen with a shorted out ear jack so it isn't uncommon. I have my suspicions about the whole speakerphone/regular mic situation but nothing solid. My guess is that speakerphone works because of a short in the wiring but I can't possibly justify that without thorough research.

In conclusion, be wary of 5.0.1 and squeeze your warranties for all they're worth. As much as I have a weakspot for apple products, I can just as easily move to a different platform without regret.

Soooooo, the new iOS fixes the audio problem. I guess the iOS upgrade was the problem all along. Well, I've already upgraded to a new phone. So do I get a refund for my upgrade cost? Maybe a refund for the two months of not having service?

I have the same fault with my phone, with the mic not working so people can't hear me on calls. It only works if I connect my headphones or use it on speaker phone - not an ideal situation. It was 2.5 months out of warranty when the fault occured.

I am just back from the Covent Garden Apple store and have been told that as I am out of warranty, i have to pay £120 to get a replacement phone which will then only be under warranty for 90 days.

Bearing in mind this fault has not been fuilly explained to me and seeing all the above comments, this could clearly happen again, so I do not understand why I should have to fork out more money for a replacement.

This is not what i was expecting at all and I feel Apple are being very mean by not acknowledging that this is a hardware fault and providing a replacement free of charge.

I was told by the Apple customer services guy that i've had bad luck to get one of these phones and that other phones last longer than 14.5 months!!!

Needless to say I will not be buying a new one and will look into Samsung Galaxys instead. Very unhappy customer.
