    Hello,
    I have Lg G3 s, I want if anyone knows why I can not lock my phone with the options below: none, swipe and knock code. But also I can lock with pattern, pin and password option. Why?
    Thank you

    Do you have any installed certificates? Maybe to connect to some Wi-Fi network like eduroam?

    I had a similar problem on another phone and that was the reason. However, I can see that it is not the case.
    So, to be clear, you can set the lock screen to anything but none, swipe and knock?

    Do you get an error or you just can't select the options?

    Go to security settings-> device administrators and see if there is anything weird. Also, go to safe credentials ou trusted credentials and, on the user tab, clear them, if there are any. These are just some suggestions that I got from a Google search...

    I tried this option I have many trusted credentials in system. Do you mean to clean them? The user tab is empty. I do not know why. Do you have another option?
    Thank you

    Try going to the system app called lockscreen settings or something like that and clearing data / cache. If that fails, try googling it further. Maybe you can find someone with the same problem. If all this fails, you can always reset to factory values. That should do the trick. There must be a less drastic solution though
