With the new layout options, UI3 requires camera layouts to be edited from the (right-click) context menu. On my android phone, this is achieved by long pressing on the screen to bring up the menu.
However, I have most of my cameras displayed on Amazon Fire tablets and I can't bring up a context menu by long pressing on the screen.
Has anyone got this to work (I'm using Fully Kiosk) If this is a non-function of Amazon Fire tablets then the UI3 would require a button to edit the layout as I can't see a way to do this currently?
