Use 180 degree as general upside down for rotation choice
The "UpsideDown" field of DisplayRotation stands for reverse portrait.
So the general up side down rotation should be ROTATION_180.
Otherwise a landscape display will get 90 as invalid and 180 as valid.
Portrait display (default h>w)
mLandscapeRotation=ROTATION_90 mSeascapeRotation=ROTATION_270
mPortraitRotation=ROTATION_0 mUpsideDownRotation=ROTATION_180
Landscape display (default w>h)
mLandscapeRotation=ROTATION_0 mSeascapeRotation=ROTATION_180
mPortraitRotation=ROTATION_270 mUpsideDownRotation=ROTATION_90

Disable auto-rotation.
Rotate the device 90-degree counterclockwise.
The rotation hint button should show.
