i don think it's help.
because i tried plug the earphone test it works.
i'm sure is not physical problem or dirty get inside the jack port.
i tried to blow the port it doesn't help and everytime i flash a new rom it works for a while then the problem come again.
the only way i found out the restore the headset earpiece speaker work is clear dalvik cache clear cache let it re-optimize those apps. then it work again.
i am wondering is it any google services or apps conflict with some services which occupied the headset earpiece speaker, so we can't hear anything while in voice call.
