Create work profile

On most devices, creating work profile is not allowed by the system when the device owner exist. Because the system add no_add_managed_profile user restriction when a device owner is set. Device owner can't modify user restrictions set by the system, but if your device is rooted, you can disable this restriction by executing the following commands in adb shell.

pm set-user-restriction no_add_user 0
pm set-user-restriction no_add_managed_profile 0
pm set-user-restriction no_add_private_profile 0
pm set-user-restriction no_add_clone_profile 0
