Vuforia SDK Version: 4.2 -Description with steps to reproduce:
1. Create new scene.
2. Add prefabs ImageTarget and ARCamera
3. Add sphere as child of imageTarget
(All like in tutorial)
4. Build android apk
Run on device (Reproduces on Prestigio Multipad PMT577_3G with 4.2.2, Samsung Galaxy S4 mini with 4.4.2, not reproduces on sony xperia sola with 4.0.4)
Result: white screen when I point my camera on marker. Camera return to normal when I lose marker (it even possible to extended tracking after, but pointing back to marker puts my app to white screen again).
-Development OS (Mac OS X, Windows, Linux): Mac OS, Windows -Mobile OS and Version: Android 4.2.2, Android 4.4.2 -Mobile Device Manufacturer and Model name: Prestigio Multipad PMT577_3G, Samsung Galaxy S4 mini -Do the Vuforia Sample Applications show the same behavior?: Not tested, but use only vuforia prefabs.

Hi there...
Have you found a solution?
same error here
white screen when found target on some android devices
It's an issue of the shading mode of Unity. I can't find the post -in the forum- where this was discussed but they've solved with setting a legacy custom shader, applied to the model (the sphere in this case).

Also ran same project on iPad Air. There are no white screen, but flashing background (like at this post: https://developer.vuforia.com/forum/issues-and-bugs/unity5-vuforia4-everything-flashing-around-my-object-when-ta) and disappearing UI.

I'm having the same problem: the screen becomes white when ARCamera tries to render some object, be it inside or outside ImageTarget. It does not happen with normal Unity Camera. It also does not happen when I set ARCamera Rendering Path to Legacy Vertex Lit.

Can someone explain this issue? Is this a bug with the new SDK update?
white screen when found target on some android devices
The problem is with the Rendering Path in PlayerSettings>Settings for Android>Other Settings>Rendering. The problem occurs when it is set to Forward or Legacy Deferred (light prepass). Setting it to the other two options worked for me on my one plus one.

This solution worked for our app that we have working on and hence a thumbs up :). But I'm curious about AdreiBackB's problem. I'm new to this. Somebody please respond.
white screen when found target on some android devices
Well, that's exactly what I don't want. I want to use Forward Rendering path.

Ok, I did the same thing maximrouf did here: https://developer.vuforia.com/forum/issues-and-bugs/unity5-vuforia4-everything-flashing-around-my-object-when-ta
and now it works :D

What do I replace it with? Sorry I am new to vuforia and I am making my Graduation Thesis on Augmented Reality. I need help as soon as possible. Thanks.

Same problem here with Unity 5.0.2f1 and Vuforia 4.2.3. Problem only occurs on android. As soon as a image target is tracked, the screen renders white. If the target is lost, the video background stream is restored. App is working on IOS and in editor.

It´s the same thing with my project. :( Please HELP!

Hi,
it seems this issue (white screen) may be related to the one discussed here:
https://developer.vuforia.com/forum/unity-3-extension-technical-discussion/vuforia-42-unity-501-ui-issue
From that thread:

You replaced those files with what? I have the same problem as AndreiBlack but I cant seem to find a way to make it work. Not sure how to "replace it".
Please help

Thanks I followed your advice and changed the shaders the way you said before. And it is working now. Thanks
white screen when found target on some android devices
What change in particular did solve your issue ?
The "queue"="Geometry" change in the VideoBackground shader ? or replacing the Shaders of your 3D models with other Mobile/Diffuse or Legacy/Diffuse shaders ?
white screen when found target on some android devices
As you said before, I looked for the EmulatorVideoBackground and
white screen when found target on some android devices
OK, thanks for confirming.
Note that you can also achieve the same effect of the "Unlit'/Texture" shader by editing the VideoBackground shader of the VideoMaterial and replacing this line:
"Queue"="geometry-11"
with this:

Same issue is also discussed in this thread:
