I checked the sample app works fine on Essential PH-1 and Pixel 4a.

I find out that View.onRestoreInstanceState method has not be called if ONYX BOOX's display orientation set horizontal. View.onSaveInstanceState method is called correctly but View.onRestoreInstanceState is not.

This problem reproduce rate is not 100%. Sometimes, ONYX BOOX may call View.onRestoreInstanceState correctly.
