Hiding the bottom navigation bar in kiosk mode

Hello everyone,

I would like to configure a kiosk mode with real fullscreen.

With real fullscreen I mean:

- no address bar (top)

- no status bar (top)

- no notifications (top)

- no navigation bar (back, home, apps) (bottom)

I'm using:

- EHS (Enterprise Home Screen v 2.6.1)

- EB (Enterprise Browser v 1.7.1.0)

- Symbol MC9200 Handheld scanner (Android KitKat 4.4.1)

I've managed to do almost anything except the "no navigation bar (bottom)" and I don't know how to do it or if it's even possible.

Did anyone managed to configure it or have any hint to share?

Thank you.
