I have a Samsung Note but am having trouble with the microphone. In the normal mode of making a telephone call the microphone does not work but if I select 'speakerphone' then the microphone works normally and I can carry out out normal phone conversation. In the normal phone mode I have tried turning 'Mute' on/off but still the microphone does not work. Does anyone have an answer to this problem please? Cheers, Toon Army.
