Hello everyone, I recently got Note3.

Today, I looked at my phone through another phone camera and found a sensor which kept blinking all the time. (Please see attached clip)
To me, it seems like an infrared since human eyes could not see it.



Is this normal even I don't have air gesture ON?

Thank you

That is the IR.

If you're using an IR remote app, and you press a key, that'll light up for human eyes to see.

How can it be the IR?

If you were using an IR remote app then you'd have to show the front face of the phone to the TV, which would make looking at the phone screen a bit of an issue.

You mistake my meaning. If you look at the top of the phone, you'll see a small dot next to the audiojack. That is the IR blaster. The blipping dot at the front is the indicator of the IR blaster. It lights up when the IR blaster is transmitting, to alert the user.
