    I'm using my key2 since two weeks, everithing goes fine but I can hear a kind of hiss or whistle while speaking with somebody on The Phone....
    Is there somebody with The same problem? Any suggestion?
    Many tks

    Do you hear this sound when you wear headphones/earphones, or just through the phone's speaker?
