Everything seems to work fine except callers can't hear me, but I can hear them fine. I have to scream really loudly into the microphone for them to hear anything and they say it's really, really faint. One caller said it would be loud and then soft?! It's been 2 days now.
I usually have full/near full bars AND 3G while making calls... I have tried it in multiple service conditions, but no difference.
