Works on speaker only

Your explanation of the problem is not too clear.
If you receive a call and you cannot hear your caller but your caller can hear you, your speaker is bad and will need to be replaced buy phone technician.
If it is that you can hear your caller but they cannot hear you, then your mouth piece is bad and need to be replaced.
Because of the Miniature nature of the Cellphone circuit there is user serviceable part

there are two speakers in every mobile one is the one which is fitted on the top center of the mobile which you listen through when you receive a call. Second speaker is placed at the back of the mobile which speaks when you select speakerphone. The speaker on top has gone bad you need to replace it.

hi,
It seems that the earpiece speaker in your phone might be not working.
Before that verify that the call volume is set to maximum while you are in a call. If still problem persists, then you have to check the earphone present in your mobile.
Please provide your ratings.
Thanks

if you cant hear caller voice. do one thing go to gallery and go to voice recorder and record some voice then save that then go to media and play recorded sound if its working means your loud speaker is working but not ear peic means (ear speaker) not working. so then you need to change ear speaker.you can do your self just watch video on online.

chek the speker if it is ok clean the speaker contact on the board,if not so then replace the board to board connecter(i mean strip)then the problem may solve.even its not working chek the tracks continuty to speaker contacts and audio ic.

keep ur finger on the (#) button that might work

Hi everyone, after spending sometime scouring the internet to no avail in order to fix this problem it suddenly occurred to me that the little holes in the earpiece may have become blocked from sitting around in my pocket. I have carefully cleaned all three of them with a pin and Hey Presto I can hear fine again without going on loudspeaker. Rgds Bill
