When a scanner device has been successfully been enrolled onto MobiControl, a Lockdown lockdown profile is applied to them by default that which limits the users user's access to the device to only being able to launch the MobileWMSMobile WMS application.
The lockdown screen can be modified to include links shortcuts to launch other apps or to launch the on-device browser to access web - resources
Examples on of that can be found here:

And if you need to access settings or other apps then than those on the lockdown then screen, you can unlock the devices following this guide: https://taskletfactory.atlassian.net/wiki/x/iJC0B
The lockdown screen can also be removed altogether if you want to provide full access to the devices. If that is the case, please let us know in a service desk ticket.
