before audio IC's.
try if your phone microphone is laying well between the board and micro phone position. check again.

CHECK your microfon position on the chasy and his conectors on the PCB / if all ok reflow ( CHANGE COBBA ) like VIVEK sayd !

Try to jumpper the mic pad's to resistor arround the Cobba IC's, it shown in 3310 service manual. if it still bad, change the COBBA Ic's and use Nokia tool.
