"StageOrientationEvent.ORIENTATION_CHANGE" event does not fire (dispatch) when the Auto Rotate feature of the device is disabled.
I'm developing a game that only must work on PORTRAIT mode. I speculate many users unchecked this option display settings.
How can I detect screen rotation regardless of device setting. Should I use accelerometer for this purpose or there is a better way?
