I am trying to use the setScreenTimeout function of CustomDeviceManager but I still get an error: "Admin does not have com.sec.enterprise.knox.permission.CUSTOM_SYSTEM".
Permission is present in my Manifest.
I activated the ELM license successfully but I still have this error.
I tried to activate the KLM license and then the ELM license but I have an error on the KLM license (invalid product key).
