I accidentally removed the KIES administrator from "Settings->More->Security->Device administrators" by unchecking it. Now if I go to the same list I see only unchecked option of "Android device manager" and no "KIES". I was disabling KIES just to check something and I expected that the checkbox implied that it would be possible to bring it back. But currently that's not an option.
The Android version is 4.3 (official firmware).
