I just noticed this. To the left of my led indicator is a small circle (proximity sensor maybe) there is a VERY dim red light. Barely noticeable but there. It is constant on. Anyone else have this, or know what it is?
mine is only ever "on" or "blinking" when i am in a call. if you're in a call and change to speaker phone you will notice that it goes off. it is definitely the proximity sensor though.
if you really wanna blow your mind, search for the red light in your trackpad. i heard that's the optical trackpad sensor. only ever saw it at 2am with no lights on, but i swear it was there and that i was not seeing anything.
