Change your earpiece.Need to know in phone have 3 kind of mic:1,microphone to make somebody hear our voice. 2.Ear piece to make we can hear for sombody voice. 3..Buzer to make phone ringing or louder sound when somebody speak (speaker). in that case your earpiece is not work,so change your ear pice. I hope it help.
you have 2 speakers. 1 ear speaker for calls and 2nd one for ringer, MP3, loudspeaker etc. Make sure your ear speaker volume is all the way up, nothing in the way ( dirt - make up - metal shavings etc ). If all is good have your ear speaker replaced.
If you are using the windows operating system, Try one of the following.
1) Check you have plugged the mic properly into the socket
2) Goto volumecontrols->advanced and then check if the mic is in muted. If yes, uncheck the option.
3) Goto Controlpanel->Sound->recording option and check if the mic is enabled. If not enable it.
4) If still its not working, Try installing audio drivers.
When you make call no body can hear you because there will be mic in your handset it might be in loose contact or the mic is damaged ...
and you cannot hear them because the ear piece speaker is also in loose contact or it is damaged ...
if you are good at opening the handset then just open it and just have a check is there any miscontact in both the mic & the ear piece speaker ...
i think the mic and ear piece speaker are not touching to the circuit board so as it is not in contact you are facing this problem .. check for the miscontact and solve it ... if they are damaged then replace with the new ones.. while purchasing the new ear piece & mic buy which is compatible to your handset model .. if you are not good in opening then just visit the technician ... he will do it ... The price of the ear piece speaker & the mic are very cheap ... if you visit the technician then he may take the service charges extra ...
any doubts reply me i am always here to assist you thank you bye ..
