Empty DeviceOrientationEvent in Web Chrome

I have a Zebra TC55 mobile and in the lastest Chrome version when I try to get orientation data the device returns a null event. If I try it with other mobiles the command is working. The code is so simple and is the next:

window.addEventListener('deviceorientation', function(event) {
console.log(event);
});

And the response is a event with all the fields empty.

DeviceOrientationEvent {isTrusted: true, alpha: null, beta: null, gamma: null, absolute: false, …}

Any help would be great. Thank you in advanced.
