Hi,

Can you hear OK on a call when using earphones with a microphone attachment that is plugged into the phone?

Can you hear OK when using the phone in loudspeaker mode (aka hands free mode)?

Is the phone in a protective case at all? If so can you hear OK when it is out of the case?

Have you checked that the volume level is OK when on a call?

What have you tried?
