What happens to a set up device when it is added to Android Zero Touch?

[MoritzS]

Hi guys,

can anyone tell me what happens to a fully set up Android device when this device is added afterwards to Zero Touch and gets its config? 

Does nothing happen until the next hard reset or is it possible that it does an reset by 'itself'?

Thank you.

Our experience was that devices added to Zero-Touch, after they have been enrolled to an MDM before, didn't result in a factory reset. This is an experience from ~2years ago when we migrated devices from one MDM server to another (before without ZT, after with) and could have changed but i don't think so.

Best is always to test with a single or few uncritical (test) devices.

Correct, nothing happens to the device if its already been configured and is not running in the Out-of-box-experience (OOBE). Zero touch is just a service that points the device to the correct MDM solution (EEM provider) that you have configured in your Zero Touch profile and the device will only download that profile wduring OOBE.

Zero touch is just a simple service just like Apples ADE or Microsofts Autopilot or Samsung KME.
