What are these Two icons? I was re-ordering objects on the quick settings When I noticed two icons that I do not recognise:



To clarify, it's HotKnot and BroadCastTile That I am questioning.

Whats odder is that they are not in the Quick settings menu (Even if I add them)



What are they for, and how can I use them?
HotKnot - The technology allows the capacitive touchscreens of smartphones to interact – a feature that can be used for quick data transfer/sharing, in a similar way to NFC.

BroadCastTile - It is just a customizable tile, you can add a custom tile if you know the constraints.
