I had my bold 9780 for over a year now, never had a problem and about 3 weeks ago it started to make high-pitch noises during calls. While those noises, the caller sounds like he is far away from his phone. The noises come and go like very quickly. It is disturbing. Does anyone have an idea what to do?
Thank you very much in advance, kind regards,

Welcome to the BlackBerry® Support Community Forums.
First verify with your wireless service provider that they are not having any reported issues with this in your calling area. If they are having no issues, I would suggest to do a clean reload of the BlackBerry® device software as shown here: http://btsc.webapps.blackberry.com/btsc/KB11320, please test before restoring any data to the device.
If this resolves the issue do a selective restore of essential data (Address Book, Calendar, Task, Memos, BBM contacts etc.)

If the issue still persists after the reload, further investigation might be required. To help further diagnose the cause, contact your wireless service provider or BlackBerry® Technical Support Services for further review and support.
