Do you observe a similar crash when running our Vuforia Core samples (unedited)?

If so, what is the device model you're using?

  • To find an Android device's model number: Settings->About phone/device->Model number
  • To find an iOS device's model number: Settings->General->About->Model (usually ends in "LL/A")
