I just bought a new Nokia 6630. However, I noticed a problem. I suppose you are familiar with the noise that comes from a radio when you hold you GSM next to it when on a call(the buzzing, interference sound). Well, I can barely hear it on the Nokia when talking. It is not very loud, but I can definitely hear it. It disappears when on the loudspeaker or handsfree. Any ideas what might be causing it? I mean, the phone is brand new. Is it a hardware fault or it is something normal? I think I've heard it on other phones, but the speaker, by assumption, should be shielded... I know it is the radio transmitter interfering with the audio amplifier/spekaer, but I am wondering what the reason for this might be? Do you think I should replace the phone? Is this present on all 6630s?
