You need to reset the orientation to SCREEN_ORIENTATION_SENSOR after a few seconds so the sensor will start to work again..
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
new Handler().postDelayed(new Runnable() {
@Override public void run() { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR); } }, 2000);
