BOLD 9900 - Can't hear callers when I answer the phone or dial out!!

[ Edited ]

Argh please help! I bought a 9900 recently and when people call me or I call out, I can't hear them! They can hear me fine when I answer but the line is completely dead - radio silence! Every other sound aspect on the phone is working fine - alarm, BB alerts, ringtones, etc


I took it to a phone shop fo repair yesterdy and they changed the speaker/mic, but to no avail. It still doesn't work. What could be wrong and is this fixable?!


Thank you.

Welcome to the BlackBerry® Support Community Forums.


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.)
How to use BlackBerry®  Desktop Software to restore data to a BlackBerry®  smartphone from a backup file

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.

Thank you

Re: BOLD 9900 - Can't hear callers when I answer the phone or dial out!!

I had this problem twice. First with a 9800, then with a 9760. I tried to reload the telephone software: didn't work. Then I solved the problem by doing something silly: I plugged my headphones to the telephone and made a couple calls switching from headphones to speaker. When I unplugged the headphones it worked. I thought I got lucky the first time but then when it happened the second time it worked for me again. Hope this helps.
