Lost "none" lock screen option in my galaxy note 3 SM-N900

[Samuel Danny]

I have rooted galaxy note 3 SM-N900
It was fine. But i dont see any "none" option in my lock screen option.
it happened after I root and add face unlock to my phone (i paid someone to do that for me).
And now "none" option is gone.
Please help me restore it.

Notes : someone who I paid can't solve it.
Thanks

The option, Face unlock, seems to have replaced the option, None.
How did you add 'Face unlock'? Could you try to uninstall it in order to resume 'None'?

I try to uninstall face unlock. After I uninstall face unlock, the face unlock is gone. And there's still no "none" option

If you go to Settings, Security, Phone Administrators, is anything checked? One or more of those apps may require a password, pin, etc. Also in Settings, Security, Trusted Credentials, the User tab may have a cert that requires a higher level of security. Some apps install a cert (such as FoxFi) that could cause your issue.

All of my apps didn't need a security. If my apps do, then I'll not be able to use swipe as my lock screen (it has no security at all)..
