The Alloy Wheel Fitment, Tyre Stretch, Rolling Radius & Speedo Error Calculator
Align the center line of your phone screen with the center divider of the VR headset lenses, secure the clips, and put on the headset.
Turn the controller off. Ensure the analog joystick is perfectly centered and untouched, then turn it back on. Calibrating the stick at boot-up usually resolves drift.
