Samsung Galaxy S2 - Android 4.4 (CyanFox 2.0)Unity 4.5.1f3 (Free version)Vuforia Unity SDK 3.0.5
When running the vuforia image sample app (v3.0.6), and my own "hello world" app that I created using instructions from here, it works just fine on my PC with my webcam but displays odd artifacting/screen corruption on my android device. The app works correctly otherwise. It appears to occur on the 'camera' layer, behind the projected 3D world. The pattern of the corruption changes every time the app is launched. Other Unity apps without Vuforia do not have this issue.
I haven't got access to any other devices right now to try on them, will when I am able. Screenshots are attached.

Hi, thanks for your report.
Could you specify the exact model number of your device (as there may be multiple flavours of the Samsung S2) ? you can find this information in the Settings panel of your device.

Thanks.
May I ask you to make the following quick tests to help us narrow down the scope of the issue:

The artifacts still exist in the provided .apk.
I'm just downloading unity 4.5.0.

Thanks :). The phone OS might be important to forward on as well (CyanFox 2.0) but this is literally the only thing that functions incorrectly on it.

I assume the Zombies from Hell app was developed with a previous version of Vuforia (the current version 3.0.5 was just released few days ago

If you've got a pre-3.0.5 APK lying around, I'll test it?

That would be great, yes please.
Also, could you open the Unity sample (or your App) and change the Camera Mode from MODE_DEFAULT to MODE_OPTMIZE_SPEED (look at the ARCamera Inspector)
and run again ?

I'll need a link for a pre-3.0.5 APK.
I've tested with MODE_OPTIMIZE_SPEED before, and it changed nothing. I'll try again with Unity 4.5: nope, issue still present.
Artifacts/screen corruption on Samsung Galaxy S2
Ok, ... there is no need for you to test on pre-3.0.5, we can verify that internally.
And thanks for the MODE_OPTIMIZE_SPEED test.
I will let you know as soon as I get news from our investigation.
