Forgive me if I stating the obvious to some but I thought Id share just in case. When using Android and Chrome a shortcut can be created to the home screen on the android phone which goes straight to full screen and prompts for username and password (username and password details can be stored in chrome if needed). To do this go to the SHAC/NAC IP address in chrome. Select smart phone visualisation. Then select the three dots top right hand corner on Chrome banner and select "Add to Home Screen". Follow the on screen prompt and place shortcut on home screen. Click on it and it will open up in full screen without address banner as if it were an app. See screen shot. I not sure if this is the same on iphone as I don't have one be good if someone could confirm. :) This can be done on any Android tablet or phone.
