With our TC70x and TC72 devices, after some seemingly random amount of time ranging from a few hours to overnight, if the devices are not used then they will go white as pictured below. Tapping on the screen does nothing but if I click the Square button I get the Administrator and Refresh Buttons. If I click the Administrator button and type in the admin password, then I can access the device like normal, everything is fine. If I then switch the device back into User mode then the white screen comes back. So it is the kiosk mode itself but I am not sure how to prevent this.
Devices: TC70x and TC72
OS: Android 8.1.0
MobiControl: 13.7.5 Build 1013
Patching: Does this on a device with no LG patches and one with most recent
