I have received reports of Vuforia problems in some android devices. This is the app: https://play.google.com/store/apps/details?id=com.TreflSA.Roar
The problem is that when the user enters the scene with the camera preview, nothing is there, just black background. Exiting, reinstalling the app or updating android doesn't solve the issue.
This is not happening in iOS, only some android devices. This makes it hard to debug, so I would like to know if the problem is not related to the plugin but the permissions or something like this that could be avoided in a simple way.
The app has been built with different versions of Unity and the plugin and all had the same issue. At the moment is Unity 5.1 and Vuforia 5.
This are the devices that had the issue:
- Modecom Freetab 9000 IPS
- Dell Venue 8 7840 running Lollipop
Thanks a lot for your help,
