Ok, we found the solution
Using ADB we can deactivate DeviceAdmin and disable the app and uninstall it.
These are the commands we have used:
adb pm list packages | grep airwatch
package:com.airwatch.androidagent
package:com.airwatch.admin.samsungelm
adb shell pm disable-user com.airwatch.androidagent
adb pm uninstall --user 0 com.airwatch.androidagent
adb shell pm disable-user com.airwatch.admin.samsungelm
adb pm uninstall --user 0 com.airwatch.admin.samsungelm
Now we can enroll our device to the new Intelligent hub for Android Enterprise.
Thanks.
