Yes. For Store Applications, the navigation bar setting has limitations on non-rooted Android Enterprise devices. The visibility of the navigation bar is controlled by the OS/device firmware in many cases, so Hexnode cannot always suppress the Back icon completely.
If the requirement is to prevent users from leaving the app, confirm that the device is correctly locked into single app kiosk and that no allowed exit action is configured. However, hiding the Back icon itself is not supported for Store Applications on standard Android Enterprise devices unless the device provides additional OEM-level controls, such as Samsung Knox navigation restrictions.
If the kiosk is web-based, use the Website Kiosk back button restriction mentioned above. The icon may remain visible, but the back navigation action will be blocked.
