My Desire has developed a strange buzz in the speaker when on a phone call, almost as if the speaker is slightly loose, if I turn the volume right down, the buzz goes......not really the answer though is it. So, my first point of call was to speak to HTC (UK) who were very friendly and have arranged for a courier to come and pick it up on Monday to take it away to investigate......7 working day leadtime. has anyone else encountered this "loose speaker/buzz" issue at all? has anyone sent their phone back for a repair? was it a good service? should I speak to service provider (Orange) instead?
