Scale camera to screen height and width

Hi!
I'm developing a game for the ios and android platforms, It's 2d and the thing is I'm running into a problem.
The app's screen is perfect let's say on the Iphone 4S but it's cut off on Iphone 6(+) and android and etc..
I don't care if you have a larger screen you can see more to the side but how do you make the camera display to fit the whole screen?

I work in c#, Thanks in advance!

Code (CSharp):

1. using UnityEngine;
2. using UnityEngine.UI;
3. [ExecuteInEditMode]
4. [RequireComponent(typeof(Image))]
5. public class Background : MonoBehaviour
6. {
7.     public delegate void OrientationChanged();
8.     public static event OrientationChanged OnOrientationChanged;
9.     private Image _image;
10.     private bool _wide;
11.     private void Start()
12.     {
13.         _image = GetComponent<Image>();
14.         _wide = Screen.width > Screen.height;
15.         if (_wide) Wide();
16.         else High();
17.     }
18.     private void Update()
19.     {
20.         var oldWide = _wide;
21.         _wide = Screen.width > Screen.height;
22.         if (_wide && !oldWide)
23.             Wide();
24.         else if (!_wide && oldWide)
25.             High();
26.         if (_wide)
27.             _image.transform.localScale = new Vector3(Screen.height / _image.preferredWidth, Screen.width / _image.preferredHeight, 1);
28.         else
29.             _image.transform.localScale = new Vector3(Screen.width / _image.preferredWidth, Screen.height / _image.preferredHeight, 1);
30.     }
31.     private void Wide()
32.     {
33.         _image.transform.localRotation = Quaternion.Euler(0.0f, 0.0f, 90.0f);
34.         if (OnOrientationChanged != null)
35.             OnOrientationChanged();
36.     }
37.     private void High()
38.     {

40.         if (OnOrientationChanged != null)
41.             OnOrientationChanged();
