Does anyone know what the icon with the 2 rectangles and arrows means? I don't see any app that it's connected to and it's still there after I reboot. I tried looking up glossaries of icons and I don't see it anywhere.
That is the "Direct/Android Beam" part of the NFC.
It allows "sharing of images or music by holding devices together"
It is under the "Share & Connect" area in Settings.
