My quest has been great, but my right controller seems to be frozen in place. It can track rotation and button presses, but not movement. I have had my fair share of chucking my controller across the room because I forgot to put the strap on, and it has a pretty major crack in it. Is there any way I could restore the tracking of my controller?
Those purple lights are invisible to the human eye. They are used for position tracking. If they fail, the controller will use just inertial tracking (accelerometer, gyroscope), which would let it rotate but not move.
If there's a crack in the tracking ring, it may have broken the connection for the lights, which would make it do exactly what your symptoms are.
