Options faults and speaker headset iphone 4s

Question

Hello people.

 

I have here an iphone 4S I just bought two problems.

I bought it second hand, and Trusting a little more than the person who sold it to me, I have not tested thoroughly before making the deal. Already half channeled the subject with him, but I wanted perfectly identied the two problems to quantify a little it's worth the arrangement.

 

The first problem is that calls the headphone sound is also low hear, as if scratching or metallic.

I understand that resolves changed the handset, which is the earpiece speaker, ie this.

 

But then you have another problem. What if I put the call on speakerphone mode, then the person you call, do not listen. I guess it's a different microphone that is used when talking in normal mode. And that piece which I know to locate. In ifixit there these options but do not know who will. And my English is rather bad.

 

You know which is the part that I want?

Answer 1

From what I've read online seems to be audio Flex. or something like that. Nor do I record audio when recording video.

I have also read that it can be dirt in the hole of the microphone that is next to the headphones, but I do not seem to solve cleaning.
