We all have seen that sometimes we have problems when talking to the phone and we can't heared by the other shouting that we are speaking inside of a barrel...i have seen this many times....so after a little research and some help from chinese forums i found that the problem is the second mic behind the phone next to the camera...(the little hole) the fix is that we disable this mic through settings and hoping that this will fix it...i also found that inside the call settings we can check the hearing aids...so you can test it and choose the best solution!!so we have

1)Check the hearing aids inside Settings-Call Settings
or
2)Open dialer dial * # * # 2846579 # * # *
2a)Enter the test mode
2b)Select ProjectMenu 3
2c)Bbackground settings
2d)Dual mic settings and check off!!

I can't tell for sure that this will help exacly cos many said that the little 2nd mic used for video sound recording...so you can try to see which fits you the most!!Im still testing both os if someone notice some changes feel free to comment!!

To forum dev..please don't move this too...and please make a general forum for pro version of the phone cos we only have development!!thanks!!

Dear pikachukaki,

I have tried the 2846579 fix and it works... for some time! Because after a while the dual mic returns to ON... Probably there is a process which is terminated due to Android memory management strategy, and when it reverts to ON the mic goes back to being problematic! There are possible options:

1- find out which process is responsible for this setting and find a way to prevent it from closing;
2- find out why that process turns dual mic on; there must be a setting somewhere, but I couldn't find it;
3- ask Genokolar what he did in his Cyanogenmod 7, because it works correctly!

I have not the knowledge nor the time to work on it now... :-( but I can beta test anything anyone will have to suggest!

Regards,

Ciumbia.

Hi, I am using MIUI 4 with the dual mic enabled in the factory settings and haven't noticed problems while calling. Just to inform you.

Sent from my U8800pro using XDA

Anyone have news about this issue? I'm going to unistall ICS because of mic problem. ATM the only rom w/o this problem is the cyano 7.2. So maybe knowing how he fixed it we can fix it in other roms too.
