This is my experience.

I tried to put a lock on the smartphone,
but there is a message that you have to input the password to put a lock on the screen.
I was troubled.
I inputed some passwords,but they were useless.

Maybe in the past I set a password but not put a lock.
But I forget the password.

This problem was solved by using this application.
