    Led is flashing/blinking really fast but faintly while I am on a call. It's as if the light blinks based on the sound of either party talking.
    This is on 9930.

    Are you sure it's the LED and not the little circle next to it?

    That's the proximity sensor, it senses your face and shuts the screen off while you're on a call.

    I think you are right.. I never noticed this in other phones, usually it is pretty much invisible (I guess they use infrared or front facing camera to determine that) Thanks!

    Yup, it's the proximity sensor.
