Answer 1

Your question was already answered here:

Try this:

1. Open your Settings.

2. Scroll down and select Security.

3. Clear Credentials.

4. Check the Screen Lock setting to see if the low-security options are now enabled.

If that doesn't work, you can revert your lockscreen security to Slide.

1. Set your lockscreen security to Pattern from Settings>Security>Screen Lock.

2. Click the power button on your phone to lock it.

3. Click the power button again, but don't unlock your phone. There should be a button labelled Forgot Passowrd. Note: On some devices, you may need to incorrectly enter the password/pattern several times until that option appears.

4. Enter your Google account credentials.

5. Your lock settings should now be Slide.

Note: With this method, the option for Slide security will still by disabled, but you should still have it as the lockscreen security on your phone.
