Zero-touch enrollment simplifies the enrollment process for Android devices. Upon first boot, the devices automatically check for the assignment of a specific configuration and download the correct device policy controller app (in this case, TinyMDM). This app then completes the setup of the managed device without requiring any action from the end-user!
To be eligible for zero-touch enrollment, you must purchase devices directly from an enterprise reseller or a Google partner. This reseller sets up your ZTE account when your organization first purchases devices registered for ZTE, and you will manage everything for your organization from this web portal.
