Problem with Gyro in Unity Android project

I would like to get a reference to Gyroscope and retreive its rotationRate.

Using code like this:

 ...
 void Start() {
   if (SystemInfo.supportsGyroscope) {
     gyro = Input.gyro;
     gyro.enabled = true;
   }
 }
 
 void Update() {
   if (gyro.enabled) {
     Debug.Log("Gyro: " + gyro.rotationRate);
   }
 }
 ...

The problem is that SystemInfo.supportsGyroscope returns false. gyro.enabled = true; doesn't do the trick, since Gyroscope.attitude keeps returning (0, 0, 0) object.

I am using Unity v5 along with Unity Remote 4, and have Dell Venue 7 connected for quick debugging. Everything worked fine just 2 weeks ago with Unity v4. Now, after upgrade it stopped working.
