Same problem with me :-when I call to someone they are unable to hear me..but when I take phone on speaker mode or use earphones they hear me clearly.such a expensive phone and having such a basic need probles is not expected from nokia. I purchased it because of faith in nokia brand. I am disappointed.
CALLING SPEAKER ARE NOT WORKING PROPERLY SOUND IS VERY UNCLEAR AND NO ,INTERNET WHILE CALLING
I too have same problem. Forced to use either speaker or head phone, otherwise no one can hear me
