Android : How can I switch from Pattern to Slide?

  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 Password. 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.
