I agree with Keith. Possibly the mic is broken and so, the sound feed wont work? have you seen a cellphone technician? or might as well, if your phone is still in warranty, why not visit the manufacturer's service center?

So last week i droped my phone
and last night
when i tried to called my friend
they couldn't hear me
i thought it was a joke
so i call another
same thing happend
and another
they still couldn't hear me
i think its was probably because of last week when i droped my phone
but it was working untill last night
So
is it because the setting of the phone?
or is it because i droped it?
sorry if im in the wrong forum
im new ):
Help Please?
