this an emergency fix for last patch was merger

using another logic to determine, when need to hide Statusbar and Navigationbar
we dont want systemui visibility reset if lockscreen still enable and ActiveDisplay force to Turn Off

Correct ActiveDisplay visibility when launch Ongoing Notifications

fix Back button navbar cant work on some conditions

since AD detect User Activity, we dont want to override UserActivity inside View, so do only if AD visibilty are Gone
