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


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


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.

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?

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?
