@markymarks Not sure what you mean by administrator but often on a computer system administrators have permissions for items like that. If you don't have administrator authority you won't be able to stop it.
If you have a eork6 issued phone with an administrator, you cannot override it. The only thing you can do is not put personal stuff on the phone. However, if it's your personal phone, that you bought and is not related to work, then there should be no adminitrator and you may have inadvertently purchased an enterprise version. Still nothing you can do about it and there should be no one peeking into you phone habits because an administrator has not been set up. If you happened to buy a used phone, get rid of it because you dont know who's looking and grabbing your passwords.
