Why does Android Device Manager not changes my password?

Question

I have an Android phone with password, but I don't remember it. I have access to the phone through Android Device Manager. I tried to change the password with it, but when I set the new password, Android Device Manager says:




The phone has a password, the password you just entered will not be used




How can I change the password? I have not logged in with Samsung and adb does not recognize the device.
