how do i disable the lock pattern on my lg vista screen

[miltk]

lg vista vs880
android 5.1.1

ever since the sys update, i no longer see the notification when the screen is locked. i have to unlock the screen in order to see if i have any notifications, and that is becoming very annoying. on the lg vista there's no disable function for the lock pattern i set.

anyone familiar with the vista? or help?
