Auto-face unlock is a very useful feature that let you save time. But sometimes, you just want to check your notifications without unlocking your device.
While your device's screen is off, this flow will await notifications from the Sms App, Snapchat, Gmail or Twitter (You can change or add other app in the notification blocs) and will disable auto face-unlock to let you look at them.
Otherwise, without notifications of these apps, auto face unlock is configured to be "on".
