Some devices are currently known to have problems connecting with Google Zero-Touch, and in doing so, have problems downloading the Ensemble MDM program information. 


This cannot be rectified within Ensemble, as it is a compatibility issue with the software within the devices. Google is working with the manufacturers to address the issues, and zero-touch may work correctly in later software versions of these devices. In some cases, the issue may be specific to a particular country or carrier variant of the device. 


Examples of devices that currently have compatibility issues with Zero-Touch:


SamsungSM-A205F (Galaxy A20)Installing OTA update resolves this issue.
SamsungSM-P610 (Galaxy Tab S6 Lite)Installing OTA update resolves this issue.
SamsungSM-T500 (Galaxy Tab A7)Installing OTA update resolves this issue.
