Bug Camera out of Focus on Android

Camera out of Focus on some Android devices. Is there a way to fix this?

 

This is happening on Pixel devices.

 

I used to have the same problem with my first AR app for Android. This C# code helped me out and it works perfectly for me, just like a normal camera does. Hopefully this works for you too

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3. using Vuforia;
4.  
5. public class CameraFocus : MonoBehaviour
6. {
7.     void Start()
8.     {
9.         var vuforia = VuforiaARController.Instance;
10.         vuforia.RegisterVuforiaStartedCallback(OnVuforiaStarted);
11.         vuforia.RegisterOnPauseCallback(OnPaused);
12.     }
13.  
14.     private void OnVuforiaStarted()
15.     {
16.         CameraDevice.Instance.SetFocusMode(
17.             CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);
18.     }
19.  
20.     private void OnPaused(bool paused)
21.     {
22.         if (!paused)
23.         {
24.  
25.             CameraDevice.Instance.SetFocusMode(
26.                CameraDevice.FocusMode.FOCUS_MODE_CONTINUOUSAUTO);
27.         }
28.     }
29. }

 

I'm sorry. I should have mentioned. This is for AR Foundation
