I recently installed some application. It asked my to accept a certificate and set a screen lock pattern. I have since uninstalled it, but I still can’t disable the screen lock (which I don’t really want).
Go to into Settings > Security > and Clear credentials
. It’ll let you change the lock code then! 🙂
If you do not know how to disable, turn off lock screen, pattern, pin, password or swipe then.
Settings > Security > Lock Screen (Swipe, Pattern, PIN, Password) > Enter the code > Choose None
