    For some reason, I can't activate android device manager...
    It is - Settings->Security->Device Administrators.
    When i click to activate it just goes back to the previous screen unchecked.

    I have Samsung galaxy s4 or gt-i9515 running the lollipop release.*

    Sorry for my bad english, im from Latvia.

    Welcome to Android Central! Try going to Settings>Security>Clear Credentials. Now try again.

    Are there any other Device Administrators listed there?
