I believe that I am having a similar issue with my ODG R7s. I am trying to use the stereo rendering sample, but cannot detect the images. However, when deployed to my tablet the sample works well. Any advice would be greatly appreciated.

Thanks

I think something is wrong with the glasses. When i run adb logcat and run the sample or the calibration tool i get lines like:

E AR      : Failed to open predictive sensor

E camhalwrapper: camhalwrapper with lock protection enabled!

E mm-camera-intf: Open sensor_init subdev failed

E QCamera2Factory: qcamera::QCamera2Factory::QCamera2Factory(): 0 camera devices detected!

I've run trough all apps installed and turned off the camera permissions restarted the device and tried again but the same thing happens.

Do you have any idea how to fix that? 

I tried with colored picture - still no result.

Hi. 

Yes. Optical see-through with vuforia config because i only have hololens as option for config. Stones and chips is also activated. 

When i tried to calibrate the device with the app, when i look at the picture it doesnt recognize the calibration image as well. I've printed black and white images is this a possible case?

Hi Djungalio,

Have you set the Vuforia Configuration file up with the proper optical see-through settings?
