OrientationEventListener (Tablet vs Mobile) 90 degree difference

Im using an OrientationEventListener to determine the orientation, but I have a problem in that the tablets are landscape and the phones are portraits by default. This means that OrientationEventListener returns a value of 90 for a portrait on tablets, but 0 for a portrait on mobile phones.

The activity I use has a camera, so I can’t change the orientation, so I use the Orientation value to reposition several elements on the screen as needed.

Is it possible to determine if the device is a tablet so that I can adjust the value accordingly. How can I determine the value of isTablet?

            if(isTablet)
            {
                orientation += -90;
                if(orientation < 0) //Check if we have gone too far back, keep the result between 0-360
                {
                    orientation += 360;
                }   
            }

int getScreenOrientation(Activity ctx)  {
  Point pt = new Point(0,0);
  try {
    Display dsp =  ctx.getWindowManager().getDefaultDisplay();
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB){
      dsp.getSize(pt);
    } else {
      pt.x = dsp.getWidth();   
      pt.y = dsp.getHeight();
    }
  return  (pt.x <= pt.y) ?  
    ActivityInfo.SCREEN_ORIENTATION_PORTRAIT :
    ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE;
  }
  catch (Exception e) {}
  return ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED;
}

This only solves the orientation problem, it does not detect if it is a tablet. In fact, most of my 7inch tabs have no problem with orientation mismatch. I found it only on my NEXUS 10 and on the TV android.
