I Built my project using Unity 5.2.4, and it worked perfectly. Thanks for the reply.

Just to exclude that it's not a "migration" issue with your project, could you:

- create a New Unity project

- import the ImageTargets-5-5-9 sample unity-package

- add your key to the ARCamera

- build and run, and see if you get the same behaviour?

I Just made a build of my project using Unity 5.1.3f1 (32-bit) and Vuforia 5.5.9 and after 30/40seconds my Galaxy S6 screen gets noisy.

Am I doing something wrong?

UPDATE:

Vuforia 5.5.9 has been released and should fix the noisy/static camera image issue reported below:

Also, make sure to check the Unity Migration Guide before upgrading to Vuforia 5.5:

We have an internal ticket already filed for the Galaxy Alpha issue with SDK 5.0.5 as discussed from this thread:

https://developer.vuforia.com/forum/issues-and-bugs/camera-focus

In regards to Galaxy S6 with the GPU image static, it is discussed in this thread:

https://developer.vuforia.com/forum/unity-extension-technical-discussion/strange-ar-image-samsung-s6

The device profile for GS6 was updated to correct the problem with GPU image randomly showing static and should be included in the latest SDK 5.0.10.
