My Gear VR/Oculus Go Controller keeps getting off-center.
When you use the Gear VR or Oculus Go controller, you may notice that the orientation is a little off. Reorienting the controller resets the on-screen pointer to the default position, making everything right again.
To reorient the controller, press and hold the Home button from any screen until the circle fills up. When the circle disappears, the controller is reoriented.
