When I load an ar scene on my phone, i got a black screen.
But i noticed that the target recognition is still working : I'm able to see 3d object when targeting my ImageTarget. I also noticed that if I close and reopen the app, I got a black screen until the app recognize a target, since the app works perfectly. But if I close and reopen my app a third time, it always freeze and the app crash.
Another weird thing is the fact that if I target an ImageTarget before the loading, I don't have the black screen. But it crash directly when I close and reopen it.
That bug happens ONLY if i install my app from the Play Store. It works fine if I install the app manually. Please note that I have to split my app because of the size ( > 250Mo).
I got that bug on Samsung Galaxy S5, Xperia and LG G3.
I know that the bug may not come from Vuforia SDK, but if you have some hint, that would be great.
Oh and btw, sorry for my bad english
