I have used my BB9900 for two months. It works really good until today. My friends heared a nuisance water fall sounds when we were during the call. My system is 7.1.0.746. Is that hardware problem? Anyone can help?

have you try to do hard reboot, my co-worker's 9810 fixed by hard reboot.
pull the battery and card out for 5 mins, and put it back

Did you dropped the handset?

Has it happened during any other calls besides the one with your friend?

May be is the carrier signal.
Try to make calls from other cell (move some miles away) and notice if it happens again.

I have tried to use bluetooth and it is clear as crystal. I think the microphone might be damaged.
