    Hey people,
    I wanted to get this to some notice because I found it actually interesting.
    I got a Lumia 640 LTE a couple of days back and I have been playing around with it and it is a gorgeous phone and a definite upgrade from my HTC 8X which I have been using for over two years now. So I was looking for cases and other accessories and I found this video on youtube about a case.



    What interested me isn't the case itself but the notification LED blinking beside the Microsoft logo in the front through out the video. So I was searching online if I missed the feature but I was sure my 8X was the only windows phone ever to sport a LED notification light and its one I miss on my 640. So is there really a hidden notification light in the 640? and if so, how to activate it??
    Please lemme know

    No LED on any of them, simple as that.

    Apparantly thats the proximity sensor blinking and it could only been seen through the camera but not by naked eye. I came to know of it just now after some looking around

    That makes sense. the proximity sensor works in complete darkness - so it must be IR.
    IR will show up on a video camera.

    Exactly. I actually just popped into this thread to make sure it had been resolved, since I had figured the answer by reading the subject of the topic. You can do the same thing filming a TV Remote. The IR transmitter at the end of the remote will flash for the camera, but you can't see it with the naked eye.
