Possible values obtained from the Hinge_Angle_Sensor

I am developing a game application using foldable devices with Unity.

I tried to obtain the angle at which the foldable device is open using the Hinge_Angle_Sensor added from Android 11. However, I could not read values from the sensor on Fold1 and Fold2, and on Fold3 and Fold4, I could only obtain three values: 180/90/0.

I would like to ask if those three values are the only values that can be obtained from the Hinge_Angle_Sensor of Galaxy devices, or if I developed it incorrectly.
