w880i microphone

[k0va]

I didn't know where to put this topic so i put it here,
Problem is that my microphone one day just get too silent nobody could her me when i talking, so first thing i do i go to service ( good one, that's what people says ),
and they replace my microphone ( it isn't so cheep ).
Everything was fine for fiew days after what people start complaining again that i m to silent.
So i use google to find out other people experience, and i find lots of people that have same problem, but no solution. (even in topsony archive )
Becouse it seems like serial bug on this phone, i decide to write post, and hope if anybody who know something about electroinc could help me.

Second problem is chargeing. when i connect my phone to adapter, it doesnt show any signs of chargeing, on usb it look like he charegeing but after a wihile battery went empty.
:S

If somebody had same problem or knows that what could be, please help, becouse i like w880i, and i wont give up just jet.

I would ask for help in se service, but i don't have god experience with any of services in my town, nobody does, so i would risk to try replace microphone my self. (if necessary, or even some chip if i could find it ) (i wouldn't ask this if this doesn't seems like serial bug in w880i )
I do have some experience with electroinc just not with mobile phones


Thx
