title: Handle orientation's change when device's auto rotate's feature is disabled in Flex 4.6
body: <p>"StageOrientationEvent.ORIENTATION_CHANGE" event does not fire (dispatch) when the Auto Rotate feature of the device is disabled. </p>
  
  <p>I'm developing a game that only must work on PORTRAIT mode. I speculate many users unchecked this option display settings. </p>
  
  <p>How can I detect screen rotation regardless of device setting. Should I use accelerometer for this purpose or there is a better way?</p>
