Home Screen

You can make Kiosk Browser SE the device home screen so that when pressing the home screen, or back button the user ends up in Kiosk Browser and not the ‘desktop’. When the device is booted Kiosk Browser SE will automatically start.

Orientation Lock.

Kiosk Browser SE can lock the screen in landscape or portrait mode. No amount of rotating the device will make it change.
