Additional Options

If you tap the down arrow from the phone grid display, it will reveal some additional options, such as:

Calibration – Select this if you need to re-calibrate your phone with the glasses.
Head Tracking / Body Tracking – With Body tracking enabled, as you turn your head within the portal, different sections of the portal will become visible. With Head tracking, the portal will move with your head.
Screen mirroring – this option will take you to Air Casting.
Capture – this option will take a screenshot of the visible area in the glasses.
Record Screen – will allow recording a brief 30 second video of whatever appears on the nreal glasses, excluding the background view (there is no camera built-in to record what you’re seeing outside of the glasses).
AR Scan – Not positive, but I think this is for scanning a QR code that is visible within the glasses.
Scan – Allows scanning a QR code from the phone camera.
