Mic volume too low 'in-call'

I'm getting constant complaints from people I call saying they can't hear me. I tried it myself calling from another phone and unless I shout I'm barely audible. If I run the voice recorder app and speak normally then it records quite clearly. Any ideas??
Cheers.

Thanks, but already tried all that. I hold the phone at the sides and talk directly into the tiny mic hole. It's just quiet and muffled but O.K. in the voice recorder app.

Quite frequently I am having the mic cut out all together during calls.  Sometimes this happens even before the call is answered.  Other times it happens during a call.  I can hear the other party fine but they can't hear me.  I've made sure the mic hole is clear and I'm speaking directly into it. 

This is happening with such frequency that I have no faith when I make or get a call that I'll be able to use the phone.  If no solution exists I'll be returning the phone quite soon. 

The problem is to the point now that the mic does not work at all on calls.  But, I have discovered that if I go to speaker during a call, then the mic starts working and the other party can hear me.

I have also determined that the voice recorder and the voice recognition in the Android keyboard can't hear me.  But, I have run the Tricorder (Moonblink) app and it is able to hear just fine.

Hi guys,

any solutions? mine sgs2 with android 2.3.3 also having the same problem. software problems?

Bump

I have the same problem, are there any solutions? 

When using the headset the volume of your calls is controlled by Settings/Sound/Volume/Media.

This needs to be set before you start the call. You cannot change it once the call is in progress. 

The 'In'call volume' accessed by the rocking swich on the left of the phone will attenuate the volume but will only allow you to send and receive audio to the maximum set on the 'Media' volume.

This is not an ideal solution because:
If you are listening to music on the music player set to for example 10 [the maximum is 15 ] and you recive a call the volume of the call will be at 10 and you cannot change it.

My guess is that the Samsung guy who designed the dialer app was in a different room from the guy who designed the Settings/Sound/Volume dialog. and they were not on speaking terms...

The best solution would be for the dialer to use 'Media' volume instead of the useless 'In call volume'.

If I worked in the Samsung office I could go down the hall and tell the guy but instead here we are typing sentences on some obscure forum that i doubt the Samsung guys even read.

So good luck and if you find a better solution share it please.
