My phone has lost its sound and when someone rings it will only vibrate then when i answer, i can hear them but they cant hear me, I have checked and it is not on silent.

how do l make my samsung s8300t ring longer?l keep missing calls because it only rings for about 10 seconds.

repair your speakers

well the ringing is from another speaker that works as a loudspeaker/ handsfree on your phone

as a preliminary check try connecting a headset and answer the phone if you can hear the other party then the problem is with the earpeice, you might want to get it repaired

change your speaker in your cellphone

Okay, here's your answer:

1. Open up your menu and go to "Settings"
2. Select "Sound"
3. Select "Alert Type"
4. And finally select ring and vibrate

Cheers!

I know it's a flip phone and I am not familiar with this model, but sometimes the <--> button on the side is pressed by accident, this can adjust the volume [*during a call*] up or down.

I'm having the same problem. However, I have discovered that it is something to do with the upper slide part of the phone. For some reason, if you push the slide down just a bit when you're trying to play music the sound comes on. Not sure how to fix this problem other than scrap the phone.

have the microphone replaced on the phone.

i had the exact same problem. basically (sounds a bit weird) but it happens if you drop your fone and the only way to let people hear you again is by dropping it again! so whenever you drop your phone you have to drop it again to fix it.
