During some calls I get a high pitched intermittent noise (bit like an old fax machine) which lasts a few seconds and repeats numerous time during the call. The person I'm talking to can't hear it. I doesnt happen everytime but is a real pain when it does. Any ideas?
Sounds like the earpiece speaker is damaged or faulty, might be worth booking it in for repair, or failing that, check with your service provider and perhaps try a new sim card
