Iphone 4 people cant hear me during calls.

will new iOS resolve the problem ? Faith....

Hi guys, I'm from Brazil.

I wish I could fix it doing the way you told in video, but after a few tries I had no success.

Now I am looking for a place to send my phone in order to fix it. If you have any tips where to send it (even out of my country).

Thanks for your help.

The only thing that work for me for this problem is go to apple and pay SGD$350 to replace it with new iphone.

this problem makes me thing thousand times to buy another iphone

I still have this problem, even after pluggin-out cables under wifi and plugging-in back and even after putting cardboard as shown on the videos to fix this problem. Which flex cable do I need to replace for this to permanently solve this issue???

Sorry if I am repeating a solution but got bored at page 20 🙂

The way I fixed this was going to: "Settings" > "General" > "Accessibility" - Then turn on "Hearing Aid Mode" under "Hearing" apparently this disables the noise canceling microphone.

It worked for me - Let me know if it sorts out any of your problems too!

Thanks

James

After i sent my iPhone 4 into warranty i saw a improvemnt and the problem does not appear as often (daily) as before, but this voice problem still exists. Before i sent my Iphone4 to warranty this problem was daily but only on 3G network, if i switch to 2G then it works. I think this is a software problem and Apple did not found a solution so far 😟

That my friend is not working, tested on my iPhone4 neverlocked, i`m not using JB. Having the same problems even on 2G and of course on 3G.

I`m sending my phone back to waranty.

Thanks a million! Seems like its working.....

Good post. I will look into this.

I'm on my second iPhone 4 (32GB). My first one had this problem. Of coourse the Genius bar has *Never* heard of this before so I was left to purchase a replacement for £120. A few months later (today), I was back at the Genius bar with the exact same problem as my first iPhone. Again, this problem is unheard of so after a diagnostics check (passed) and a restore (no effect) and verifcation that the SIM works in other phones my only recourse was/is another replacement for another £120. I decided to pass. I own 3 Macbook pros, 2 mini's, 2 AppleTVs, 2 iPhones, a iPad3, a Time Capsule, an Airport Express and countless iPods (my house is an Apple Shrine). I now also own an Android phone. Its definitely not a better device, but it does actually work as a phone.

Maybe I'll be back for the 5 but after the cost, time, and the way they treat loyal customers I'm not so sure.

After sending my iPhone4 to warranty the second time, I received a brand new iPhone 4 replacement. I just hope that this one works okay 🙂

Hello,

I have the same problem on my iPhone 4 16GB

Apple ask me that this is a software problem so i tried different solutions:

- restore phone: not working

- plug/unplugg headphone: working sometimes but not fixing the problem

- use Hearing Head Mode: working 2/3 days and after the problem still appears

I precise that vocal memo are working fine on my phone, this is just during a call

And after several months of problem i finally found a solution !

This is not a software problem, this comes from the hardware. All you need to fix it is a screwdriver and a cardboard. The solution is described here: http://www.youtube.com/watch?v=0jhWxYTVxe4

This works fine for me and i don't have any problem since several weeks (mainly i don't have to pay for repairs or a new phone)

I hope it will help you

Hi there I just experienced this problem today.. I had made a phone call this morning everything was fine. 2 hours later I made another call and could not hear anything. They called me back and I kept saying hello etc.. We texted and they said they could hear me. So I turned my phone off still did not work. Rebooted it. Recorded my voice and that seemed fine. Made another call and it only worked when I pressed speaker.

So searched it up and saw where it said restore it... no way I was doing that... take it back to att... maybe. Then I read to use the dust air compressor SOOOO I tried that and it worked barely as in I was pressing my phone up so hard to my ear to hear it... I sprayed more and I thought I messed it up pretty bad bc I didn't hear anything at all lol Then I see the youtube videos taking it apart... Don't have the tools to do that. SO I turned my phone off again and sprayed the top speaker close then a few inches away and kept my phone off for about 5 minutes.

It works!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I can definitely hear it better than before but its not as good. But hey its working. Hope this helps someone out =]

Today 09/07/12

What I have just done is by hardly pressing the back of your phone and the so call the silence revived instantly thank God I don't waste any money for apple or phone engineers again

I had a similar problem and havent seen the solution that worked for me posted anywhere so thought I would post here. My issue was people said they could barely hear me on calls. The phone has worked perfectly for about a year and a half but last week the problem started. I tried soft and hard resets but those didn't work so I took it to my local apple store. They fixed it by going to settings > sounds > ringers and alerts. The slider was nearly all the way to the left edge and the woman from the genius bar simply moved the slider to the middle. Problem solved. Obviously the ringers and alerts setting should not impact the microphone volume but apparently there's a software glitch that does. Simple solution that's worked perfectly for me. Hope this works for others.
