Morning. I purchased the BB Bold 9930 for my husband and he is having issues with his call quality. He says he can hear me fine, but he sounds like there is running water, waterfall in the background. We have tried this on several phones, different locations. It still sounds bad. He does not have a case/cover on the phone and we ensured all plastic was removed from the phone. I searched online and it seems others have this problem however, no 'fix' has been suggested. I ensured he is up to date with his OS. Any suggestions? I bought thru wirefly and have 14 days to return. He loves the phone, but the quality of the call is a huge issue. Thanks for your help.
