How to reproduce:
1. Open the attached "862093orientation.zip" project
2. Build and run on android device
3. Run the app keeping the device portrait oriented. The label should read "Portrait"
4. Tilt the device 90 degrees counterclockwise. The UI should autorotate and the label should read "LandscapeLeft"
5. From now on, keep the device with this orientation, do not rotate it anymore
6. Press the LandscapeLeft button. This will disable autorotation and force the screen to stay oriented in LandscapeLeft. The label should show LandscapeLeft
7. Press the LandscapeRight button. This will force the screen to stay oriented in LandscapeRight (upside down for you). The label shows "LandscapeRight"

Expected result: the label reports the device orientation, and it should not be dependent on the screen orientation. It should always read LandscapeLeft if the device is tilted 90 degrees to the left!
