QScreen::orientation() does not return actual screen orientation on android

QScreen::orientation() does not return actual screen orientation on android if it was not specified by setOrientationUpdateMask. But acording to documentation ( http://doc.qt.io/qt-5/qscreen.html#orientation-prop , http://doc.qt.io/qt-5/qscreen.html#setOrientationUpdateMask ) setOrientationUpdateMask() should affect only orientationChanged() updates.
