title: Face detection not working for Front Camera
body: <p>So basically, i have this code, </p>
  
  <pre><code>        if(mCamera.getParameters().getMaxNumDetectedFaces()==0)
          {
              System.out.println("Face detection not avaliable");
          }
          else
          {
              System.out.println("Max faces: " + Integer.toString(mCamera.getParameters().getMaxNumDetectedFaces()));
          }
  
          mCamera.setFaceDetectionListener(new FaceDetectionListener() {
  
              @Override
              public void onFaceDetection(Face[] faces, Camera camera) {
                  // TODO Auto-generated method stub
                  System.out.println("Face detection callback called." + Integer.toString(faces.length));
  
  
              }
  
  
          });
  </code></pre>
  
  <p>After calling <code>mCamera.startFaceDetection();</code>, the callback is called, everything works as normal. However, if I change cameras, the same code results in the callback never being called. The <code>getMaxNumDetectedFaces</code>, returns 35 for both cameras, so I assume its supported on the front camera. I can change the camera back and forth, calling this code each time, and it will work for the back camera but not the front one. </p>
  
  <p>Is there anything else I might be doing wrong?</p>
