Hi there, I compiled the example scene that you've provided in Android Studio with no errors. The APK installs no problem on my Samsung Note8 (Android 7.1.1). When I'm running the application, I get the permission request to use the camera. I permit the application to use the camera. I hit the start key and can see the GUI. The detection doesn't work.I see is the honeycomb graphic overlay with the GUI buttons but no plane detection is happening. Re-installing the application or restarting the phone doesn't help.
I installed the exact same APK on a Samsung S8. The exact same APK works and allows me to successfully place the astronaut. With that said, the tracking is terrible. It can't be compared to ARKit or ARCore. The astronaut slides up or down from the anchored position. Getting closer to the anchored location of the astronaut doesn't result in it zooming but slides it further down.
Here is the video of the "working" markerless app, on my old S8:

Here is the exactly same app on my brand new Note8:

Any suggestions before I get into heavy debugging?
Would love to have an official response about this issue.
I've been developing a cross platform ground plane app; it works perfectly on iOS. On android, plane finding finds planes successfully but there is only rotational tracking.
I installed the Reporter asset to check out runtime logs; there are no errors. It mentions that it did start the Positional Tracker.
Is this issue on the Vuforia team's radar? I also tried 2018.1b4 which includes Vuforia 7.1; I have the same issue.
It happens in both our custom project, and with the GroundPlane demo asset scene.
