What to do when I have forgotten my secure zone pattern in Lenovo K5 Note?

Hey Sandra, you can try this

From android 5.0 L, user can reset his password/pin/pattern by using Android Device Manager(ADM).   

  1. User need to firstly sign in with his/her google account in phone, then enable “Android Device Manager” under Settings->Security->Device Administrators.
  2. Then go to https://www.google.com/android/devicemanager to reset his/her pattern.
