Vuforia SDK Version: 3.0 -Description with steps to reproduce:
1 - Background an app on iOS 8 after the camera sucessfully inited.
2 - Return to the app.
3 - 80-90% of the time the camera will display a black screen, and there is no noticible state change on any public variables to tell that the CameraDevice isn't working correctly. Repeat steps 1-2 as necessary.
Forcing the CameraDevice to reinit manually fixes the issue.
-Development OS (Mac OS X, Windows, Linux): Mac OS X -Mobile OS and Version: iOS 8 -Mobile Device Manufacturer and Model name: All -Do the Vuforia Sample Applications show the same behavior?: The Vuforia sample application for Background Texture Access crashes on boot. Built with Unity 4.5.4.
Background Texture Access iOS 8 Black Screen
We are also witnessing this issue. We have seen to occur with both the background texture access method and the regular camera background. If we background the application and immediatly reopen it the camera goes black.

This may be the same issue (there are some differences, but maybe you could check for the error message I posted to make sure): https://developer.vuforia.com/forum/issues-and-bugs/vuforia-fails-initialize-camera

Update:
The pause/resume BTA issue should be fixed in the coming SDK 4.0 release (not the current "beta", but the final 4.0 commercial release that is expected soon).
