Problem with microphone (i4gs+)
 

Hello,

I have a problem with microphone in my phone i4gs+ (is the same model like sciphone 4g and hiphone 4g etc).

I've just received this phone and any caller dont hear me if I talk to him.

The problem is the same like in sciphone. The microphone is too quiet.

I just found about enginner mode, but the code from sciphone doesnt work on my phone.

I'm completely resigned, do you have any possible solution?
