This is a subject that has been brought up many times with no resolution. I would like to try again due to the severity of the issue. On the X when you hit the end button on a call there is a beep. This is not too bad unless you have a bluetooth in your ear. For some reason it is very loud in your ear with the bluetooth. I am on the phone all day and this is a major problem. I even bought a different brand of headset to no avail.
