Fully managed device for work-only company-owned devices
Fully managed devices are company-owned and used exclusively for work purposes. If a device is set up as fully managed, Android Device Policy automatically applies policy settings to the entire device. This makes it possible to apply the same policy to fully managed devices and devices with work profiles.
Dedicated devices (formerly called corporate-owned single-use, or COSU) are a subset of fully managed devices that serve a specific purpose. Android comes with a broad set of management features that allow organizations to configure devices for everything from employee-facing factory and industrial environments, to customer-facing signage and kiosk purposes.
Dedicated devices are typically locked to a single app or set of apps. Android 6.0+ offers granular control over a device’s lock screen, status bar, keyboard, and other key features, to prevent users from enabling other apps or performing other actions on dedicated devices.
