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?
