Input.compass horizontal shaking

Questions & Answers

Hi all!
I’m trying to build some sort of compass app (android). Simply via a camera oriented to a canvas(with webcamtexture) and the sprites which oriented around my camera( with a degree marks).
Unity 5.3.1f
The image to understand:

When I turn my phone in horizontal projection those degree marks are not turning smoothly. They are quite shaky. The video to understand:

Any ideas why it’s so shaky? And how to fix that?

The code:

using UnityEngine;
using System.Collections;

public class QM_Compass : MonoBehaviour {

private Transform myTransform;
public int facingDir;
public int degreeOffset;
public float test_float;
public Transform scrollBar;

    void Awake()
    {
        Input.compass.enabled = true;
        Input.location.Start();

    }

	void Start ()
    {
		myTransform = transform;
	}
		void Update () {
        test_float = Input.compass.trueHeading;
        if (test_float > 360) test_float = test_float % 360;
        transform.eulerAngles = new Vector3(0, test_float, 0);
        degreeOffset = facingDir = (int)test_float;
	}
}

It looks like you are getting the data that is available to you, but the data is inaccurate. I would try checking Compass.headingAccuracy over a series of frames and see if you are getting reliable reading, and if you are that is doesn’t have inaccuracies.
