I have been trying to elevate an internal Demo App to Device Owner on my rooted S8 and keep having problems.
Ways I have tried:
1) NFC provisioning (as explained here )
When using NFC with Android Bean to set the Device Owner the S8 shows a "Cannot create working profile due to the security guidelines of your device"-error
2) Adb provisioning (from console):
When using
dpm set-device-owner my/app/namespace/.DeviceAdmin
in a windows console I get the following error
java.lang.SecurityException: Neither user 2000 nor current process has com.samsung.android.knox.permission.KNOX_PROXY_ADMIN_INTERNAL.,com.sec.enterprise.permission.MDM_PROXY_ADMIN_INTERNAL

Adding the missing permissions to my manifest did not change anything.
3) Create xml-file manually (as explained here )
In this case I can create the xml in the right folder, but when I restart the phone the file gets deleted and my app is not registered as Device Owner
Are there any more ways I could try or does anyone know where the problem is?
