Hey, Thanks for reaching out to us.

To disable the full-screen mode of android devices you can go to policy-> kiosk lockdown-> advanced peripheral settings-> disable full screen. If you want to exit the Web app and go to the home screen, we have no option for that in a single app kiosk. You can add the app inside the multi-app kiosk, this will enable the user to exit the app when not in use. Click here to know more about the single app kiosk.
For configuring the Wi-Fi settings in the kiosk, please navigate to Peripheral settings under Android Kiosk Lockdown. Beneath network, you will have the option to enable the user to turn Wi-Fi ON/OFF, Connect or switch between networks and also connect to hidden Wi-Fi networks. Click here to know more about enabling Wi-Fi settings in Kiosk.

Hope this helps.

Cheers!
