QRCodeTrackingSupported returns false in build but works in Editor

I’m working with the Meta MRUK QR Code Detection sample. The QR code detection scene works perfectly in the Editor, but when I build the project for Quest 3, the property QRCodeTrackingSupported is not have a green tick:

Due to this, the QR Code is not getting detected. This functionality works perfectly fine in the Editor and is detecting the QR codes properly as well.


Here’s my setup:

  • Unity 6000.1.4f1
  • OpenXR 1.15.0
  • Meta XR SDK v79
  • Meta Horizon OS v 79 (Quest 3)

Has anyone seen QRCodeTrackingSupported return false only in build? Any guidance on the correct setup or SDK version needed for QR code detection on Quest 3 would be really appreciated.

Thanks!

Just double checking, but have you enabled experimental features in both your app manifest and on your headset?

**Meta XR Core SDK and MRUK are both on version 78.0.0

Thanks, I didn't know that we had to run a separate ADB command to enable experimental features on Quest, I thought enabling the developer mode from settings would be enough. It is working now, thanks a lot! :)
