Android Zero-Touch-Registrierung
In brief
Android zero-touch enrollment is a Google process for Android Enterprise with which company smartphones and tablets are automatically integrated into the company's device management when first switched on. The reseller registers the devices with the company in advance for this. Before sale, a device must be removed from the zero-touch configuration, otherwise it will register with the old company again even for the new owner.
How zero-touch works
Android Enterprise is Google's program for business use of Android. With zero-touch, an authorized reseller assigns the purchased devices to the company's account via their IMEI or serial number. The company links them to a configuration for its mobile device management. When an employee switches the device on, it loads this configuration and sets itself up as a company device without any manual steps. This also happens again after a factory reset.

What to note when retiring devices
Automatic enrollment is practical in operation but an obstacle when reselling. Before handing over, you should release the device from the zero-touch configuration or account, remove it from the MDM and erase the data. For Samsung devices, the same applies to Samsung Knox.
