Every managed Android device has an app in charge of its management. When that app is the device owner, set during first setup on a new or factory-reset device, the organisation controls the whole device. Android calls this a fully managed device.
That control is what field, delivery, warehouse and ward teams need: work apps install and update without prompts, Wi-Fi and VPN are configured before the device reaches the user, staff cannot switch off the passcode or install unknown apps, and a lost device can be locked, put into lost mode (Android 11 or later) or factory reset from the console.
The device-owner app is usually Google's Android Device Policy, driven through an EMM. Some fleets need their own custom DPC instead, for example devices without Google Play, or controls no EMM exposes. We build both routes and help you choose between them.
