Promethean LE boards - User Restrictions

[petben]

Hello sorry this is a repost, it was sort of incorrectly in the hardware forum. We have some Promethean LE boards and the Android OS is everywhere, really easy to get in to and quite difficult to get out of, there seems to be very limited management potential If anyone has these LE boards and is successfully using them in classrooms I am very interested to make contact.

 

1. I have disabled the floating blue ball menu
2. I am already removing the side bar menus
3. How can I prevent the swipe up from the bottom menu

    

 

1. If this can not be disabled (I bet it can't) , if accidentally gone into how do you get out of these screens and back to the HDMI source (the laptop)? Pressing the input button on the remote control bring up a load of other options that need scrolling/selecting and OK.

 

1. Finally all these system settings can be accessed and changed by a student if they find an empty room, they could change display settings, security, factory reset etc etc. I know there is set screen lock PIN but this will need to be known and used by all the teachers, it would never be kept secret, how would cover staff know it? It would never work. We need a set ADMIN settings PIN, is that possible?
