I am getting a black screen when I use vuforia on a nexus 9 tablet. I use the latest unity 5.1.1f1 and the latest vuforia 4-2-3 version. I've tested my app on different Android phones / tablets (Sony Xperia Z3, Samsung Note 3, Samsung Galaxy S4 and S5, Nexus 9 tablet and Samsung Tab 3) and it worked on each of them except for the nexus tablet. The S5 and Nexus tablet have the same Android version (android 5.x) . So the issue can't be caused by the android version, right?
I also checked if the camera had the right permission, which was true. I have no idea why it works on each android smartphone but not on the nexus 9. Any ideas?
This is the complete overview of the Player Settings:

Note: if you're using Vuforia 4.2.3, you may want to upgrade to the latest Vuforia 5.0.5.
