Hi,
Sounds like interference with your phone. A lot of times, florescent lights or other electrical devices can interfere with your phones signal. Does the noise happen when you are in a particular spot, or does it happen if you are in a completely different place?
Doc
It does it everywhere! I've been in my car, I've been in the middle of the yard, in the apt, in a dealership garage.
Are you using just the phone itself, or are you using a Bluetooth headset? Also, what OS are you using? Go to Options>About and it will be listed there.
I'm using the phone itself. OS- would that be 5.0.0.713
