When connected to my headset (Discovery 975), the Storm LED flashes blue as usual. I just recently noticed that when I am actually on a call using the headed, the upper part of the LED window flickers dim red, while continuing to also flash blue.
Does everyone's do this? and what does it mean?
Update: One thread suggests this is an infrared face detection light?

Though I cannot say with 100% certainty, I think it is indeed the face detection technology. It flashes like such on mine as well, and my S2 properly turns off the screen when I am on a call and the phone is up against my face.
