Use Accelerometer for Roll-a-ball Movement

I'm working on maze game for Android in Unity 5.1.1f1 and I have troubles with controlling my ball with accelerometer. At start I tried:

Code (CSharp):

1. public class PlayerController : MonoBehaviour {
2.  
3.     public GameObject sphere;
4.     public Camera camera;
5.     public float speed=200;
6.  
7.     private Rigidbody myRigidBody;
8.  
9.     void Start()
10.     {
11.         myRigidBody = gameObject.GetComponent<Rigidbody> ();
12.     }
13.  
14.     void FixedUpdate()
15.     {
16.         float moveH = Input.acceleration.x;
17.         float moveV = -Input.acceleration.z;
18.  
19.         Vector3 move = new Vector3 (moveH, 0.0f, moveV);
20.         myRigidBody.AddForce (move * speed*Time.deltaTime);
21.     }  
22. }
23.  

But the ball is not moving as it should. Then I tried another solution. But my ball still doesn't move right. It seems like it's sometimes hard to move left/right/forward/backward, also it's possible my ball will rotate in the opposite direction.

Code (CSharp):

1. public class PlayerController : MonoBehaviour {
2.  
3.  
4.     public float speedAc = 10;
5.  
6.     //accelerometer
7.     private Vector3 zeroAc;
8.     private Vector3 curAc;
9.     private float sensH = 10;
10.     private float sensV = 10;
11.     private float smooth = 0.5f;
12.     private float GetAxisH = 0;
13.     private float GetAxisV = 0;
14.  
15.     // Use this for initialization
16.     void Start () {
17.  
18.         ResetAxes();
19.     }
20.  
21.     //accelerometer
22.     void ResetAxes(){
23.         zeroAc = Input.acceleration;
24.         curAc = Vector3.zero;
25.     }
26.  
27.     void FixedUpdate () {
28.      
29.         curAc = Vector3.Lerp(curAc, Input.acceleration-zeroAc, Time.deltaTime/smooth);
30.          
31.         GetAxisH = Mathf.Clamp(curAc.x * sensH, -1, 1);
32.         GetAxisV = Mathf.Clamp(-curAc.z * sensV, -1, 1);
33.          
34.         Vector3 movement = new Vector3 (GetAxisH, 0.0f, GetAxisV);
35.         GetComponent<Rigidbody>().AddForce(movement * speedAc);
36.     }      
37. }

Can someone help me, please?
