Hello @Fabricio_Leite,
It sounds like your device is on an earlier firmware than 8.1 .
The Joya A6 did not have setup wizard (Hi there…) until Android 8.1 .
However, Joya A6 was bundled with SOTI MobiControl.
You would need to use the SOTI Mobicontrol app to enroll.
If you need functionality supplied by enrolling from the Hi there screen, you would need to update to 8.1+
A lot of the documentation online only covers how Android Enterprise behaves currently.
You may find enrolling via the app satisfies your needs, even though newer documentation suggests enrolling from the Hi there screen is required.
