Microphone iPhone 3g problem....


Hi.
I am an Italian user, sorry for my broken English.
I own an iPhone 3G 16GB.
I write because the phone has problems with the microphone.
The microphone is not working properly.
Details:
1. The microphone (the internal component) works, that's for sure!
2. The cavity of the microphone is not clogged.
3. During the call and the applications (*****Off/vocals memo), microphone detects the sound sporadically.
4. The microphone is operating properly for several hours, but also the reverse!

How is this possible?
How I can solve?

Hello,

We had a similar problem.

Try to replace the entire flex and microphone. Clean the connector on the system board. The problem should be resolved.

I elimate the flex of the microphone. I installed 2 cables directly replacing the flex. I also replaced the original Apple microphone with a microphone nokia 1200. The problem is still there. Sound is disturbed or absent. However, the problem is sporadic Which connector I have to clean?
