Caller's can't hear me!

When I answer or make a call the person on the other end either can't hear me or my voice is vauge. I have tried making a voice memo normally and with a headset and the normal one is very quite where the headset is loud. Also if I put my phone on speaker phone while making a call the other end can hear me perfectly!!

Please Help! Don't like the fact that other people can hear my whole situation.

I couldn't hear the speaker on the other end and they couldn't hear me. I used a toothpick to clean out the microphone and speaker holes in the phone and found there was a slight piece of debris in the microphone. Voila! It's fixed now.

I have 3 solutions

this works on Iphone 4

i have tested all 3 of them, and have had success with all 3 solutions..

The Problem:

Iphone 4 lower microphone stops working.

recording video and memos works fine, but people cant hear me during calls.

just to clear things up for everyone...

when using video recording, memos or anthing else that can record your voice, the iphone is using the TOP MICROPHONE.

when calling/getting calls the iphone will be using the LOWER MICROPHONE.

When you put it on "Speaker" then the phone will use both.

Solution 1:

Change the Dock Connector

if that wont work... then....

Solution 2:

Click on this link, and follow the instructions, on how to fix the Compiler Chip.

iPhone audio problem: fixing an audio compiler chip fault

sounds and looks wierd...., but yes it works....

done it with multiple phones so far...

if solution 1 does not fix the problem, then solution 2 should help allot.....

should the problem still persist, then you might have a problem with your Home button.

See Solution 3 for more info

Solution 3:

Change the Home button.

this last solution was the problem solver for me... i had 7 dock connecters, new and from other broken phones i tested with.

in the end, the home button just gave up when i was swapping around, then i just replaced it, and Voila.... my microphone was working again, and my home button was working too :D

i cant really explain what really happend, but its my 4th iphone i have had these problems with, and all has been repaired with these 3 simple solutions...

i really hope it can help alot of people in here, with issues with iphone 4 microphones not working

Your either looking at the microphone (which is connected to the charge port) or the noise canceling microphone.. They are both parts that can be replaced at a local apple repair facility or you can go to the closest apple store and have them replace it.
