Camera Focus BUG, Focus is not working in IOS Vuforia: 7.0.47 [SOLVED]

Unity: 2017.3.1p2
Vuforia: 7.0.47
Xcode: 9.2

Test on devices: Iphone SE, Iphone X, Iphone 6s, Iphone 8, Iphone 5.

this Code not work (((

Code (csharp):

1.  
2. using System.Collections;
3. using System.Collections.Generic;
4. using UnityEngine;
5. using Vuforia;
6. public class CameraFocusController : MonoBehaviour {
7. // Use this for initialization
8. void Start ()
9. {
10.   VuforiaARController.Instance.RegisterVuforiaStartedCallback(OnVuforiaStarted);
11.   VuforiaARController.Instance.RegisterOnPauseCallback(OnPaused);
12. }
13. private void OnVuforiaStarted()
14. {
15.   bool focusSet = CameraDevice.Instance.SetFocusMode(
16.    CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);
17.   Debug.Log ("Camera Focus is set: " + focusSet);
18. }
19. private void OnPaused(bool paused)
20. {
21.   if (!paused) // resumed
22.   {
23.    // Set again autofocus mode when app is resumed
24.    CameraDevice.Instance.SetFocusMode(
25.     CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);
26.   }
27. }
28. }
29.  

Methods
CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_MACRO);
CameraDevice.Instance.SetFocusMode(CameraDevice.FocusMode.FOCUS_MODE_INFINITY);
do not work too...

How to fix this problem?

 

SOLVED:
1. Added standart CameraSettings script on ARCamera

Code (csharp):

1.  
2. using UnityEngine;
3. using System.Collections;
4. using Vuforia;

2. We wait 10 seconds, we offer the user to scan again Vumark. And Run this code:

Code (csharp):

1.  
2.     public void Execute()
3.     {
4.         CameraDevice.Instance.Stop();
5.         GameObject cam = Camera.main.gameObject;
6.         cam.SetActive(false);
7.         cam.SetActive(true);
8.         CameraDevice.Instance.Start();
9.     }
10.  

3. camera focus )

 

@skdev3

Hy @skdev3 I am facing same problem Camera gets blurry and focus not working on Iphone se,6s,7. I have tried your script but its not working for me.i am tracking on 30 to 45 angle and it works on Iphone6 and ipad but not on 6s,se,7. Please Help..THANK YOU...

 

@skdev3 looks like you are restarting the camera to give Vuforia time to get tis settings correct. I tried your implementation but unfortunately didn't have any success with it. Calling Execute() after 10 seconds just flashes the camera view, but still no autofocus on iPhone 7 Plus.
Running Unity 2018.1

 

Because autofocus is only available again in ARKit 1.5, I would double check you are using the latest version of Vuforia (I’m not sure but if you migrated your project from an older version of Unity to 2018.1 you may still have an older version of Vuforia). I would also be sure your device is running iOS 11.3 or above as that’s the version that shipped with ARKit 1.5.

I would test a brand new test project in 2018.1 on an iOS 11.3 or above device just to test.
