Test on one iOS device and one Android device. Navigate to an SCORM activity and open the player. Check that if you rotate the device to landscape, fullscreen is enabled. Check that if you rotate back to portrait, fullscreen is disabled. Check now that toggle fullscreen button on toolbar works in both portrait and landscape. Note: When on fullscreen, bottom tabs bar may disappear. Header toolbar will change to black and white, back button and title will disappear. Also System status bar will disappear (where the clock is). Note 2: When using table of contents to navigate fullscreen may be disabled.
