Having problems running this example on different devices

[Nicklas1989]

Greetings

This example does not work on different devices for me. I have a Nexus 5 smartphone on which the example works perfectly fine. But i also tried to use it with a Samsung Galaxy S4. On the Samsung nothing happens when i start the example. It just shows me a static picture and some sensor data, but it does not react to any movement of the smartphone. And sensor data also does not change.

I have installed the latest firefox nightly on both device. I also install the webVR addon. Both smartphones run on android 5.x.

Can you tell me the reason why it is not working on the Samsung device?
Sry for my bad english, i hope its possible to get my question.
