Do you know how to remove this message?
Remove "locked by android device manager" without factory reset. 

Here are the steps:


Ask the owner in order to get the passcode or password
(Once you have the passcode or password) Go to settings > Lock screen
Enter passcode or password
Select none or whatever you choose to use
In order to see it, swipe down from the area at the top (Notification panel)
You will see a new (android device manager icon) at the top of your screen. The icon looks like a raindrop (green in color) with a bullseye (white in color) icon inside the circle
Tap and hold the ADM (Android Device Manager) icon
Tap app info
Tap Manage Space
Tap clear all data


Now the icon has been removed.
