I have made an application using unity and vuforia. It all worked well to samsung galaxy tab 10.1, 7 and galaxy note of the previous generation. Then when trying it on Samsung Galaxy Tab2 10.1 with Android 4.0.3, Model:GT-P5100 and kernel: 3.0.8-482645 and the 7" version it won't work. The funny thing is that it will work on the Galaxy Note with 4.0.4 Android, but the previous 2 models can't update to that android firmware. By the way, the application starts but after the splash screen it shows a black screen. When pressing the home button, you can see that the camera gets activated but while returning on the application it crashes.
Also i had the crash problem after returning from a web link to the application on the previous generation tablets. Anyone have a tip? I'd be glad!
