November 6, 2019 update:
  • There's a new open source Cardboard SDK that offers a streamlined API, improved device compatibility, and built-in viewer profile QR code scanning. We recommend that all developers actively building for Google Cardboard migrate to the new Cardboard SDK: iOS, Android NDK, Unity XR Plugin (SDK)
October 15, 2019 update:
  • The Daydream View VR headset is no longer available for purchase. However, you can continue to use the existing Google VR SDK to update and distribute your apps to the Google Play Store, and make them available to users in the Daydream app.

Degraded controller performance

If controller tracking performance degrades, gets stuck in position, or disappears completely, try these steps to remedy it:

  • Bring the controllers in view of the faceplate.

  • Unplug the faceplate and then plug it in again.

  • Power cycle both controllers.

  • Replace the existing batteries with fully charged AAA batteries.

  • Try moving to a room with different lighting conditions. (Fluorescent lighting and HTC Vive lighthouses are both known to interfere with tracking.)

Flaky Bluetooth pairing

  • If bluetooth pairing becomes flaky, power cycle the controller. If this doesn't fix the issue, re-pair the controller.

Battery life

  • Save battery life on the headset by unplugging the faceplate when not using the headset for extended periods of time. Keeping the experimental 6DoF faceplate plugged into the Mirage Solo significantly reduces the battery life in standby.

  • Save battery life on the controllers by switching the controllers off when you’re not planning to use them.
