title: Vuforia camera low device camera resolution with Unity
body: <p>How can I force device camera to use highest resolution for AR camera?
  I used Vuforia 6 and Unity 5, but when I publish my app and used on device that has 8mb camera sensor, camera view in app is very low resolution. I think it's 640X480, and it zoomed. </p>
  
  <p>In Unity Vuforia configuration setting I set camera device mode on "MODE_OPTIMIZE_QUALITY" but it doesn't change on resolution.
  My device: Samsung Galaxy Note 12.</p>
  
  <p>I used this script:</p>
  
  <pre><code>Screen.SetResolution(1920,1080,true);
  </code></pre>
  
  <p>and assign to ARCamera but it don't have change. 
  It should work for any device. </p>
  
  <p>How can I fix this?</p>
