so i just replaced the screen on my 680. screen works great, i can text and make and receive calls. i can hear the person on the other end, but they cant hear anything i say.

ive tried it on speakerphone as well and i can still hear them, but they cant hear me.


anybody have any ideas? im guessing i messed something up when i took the phone apart to replace the screen, but i dont want to just go poking around in there when im not sure what i should even be looking at fixing.

thanks in advance
