I've tracked down why some apps don't changed the status bar for tablets running ICS. There was an API change where tablets now use a different method to dim the status bar. I already passed this along to the Plex team who have put it in their test build for their next release. If you have an app you'd like this put into please pass the following information along to the dev team:
Controls for system UI visibility
Since the early days of Android, the system has managed a UI component known as the status bar, which resides at the top of handset devices to deliver information such as the carrier signal, time, notifications, and so on. Android 3.0 added the system bar for tablet devices, which resides at the bottom of the screen to provide system navigation controls (Home, Back, and so forth) and also an interface for elements traditionally provided by the status bar. In Android 4.0, the system provides a new type of system UI called the navigation bar. You might consider the navigation bar a re-tuned version of the system bar designed for handsets—it provides navigation controls for devices that don’t have hardware counterparts for navigating the system, but it leaves out the system bar's notification UI and setting controls. As such, a device that provides the navigation bar also has the status bar at the top.
To this day, you can hide the status bar on handsets using the FLAG_FULLSCREEN flag. In Android 4.0, the APIs that control the system bar’s visibility have been updated to better reflect the behavior of both the system bar and navigation bar:
The SYSTEM_UI_FLAG_LOW_PROFILE flag replaces the STATUS_BAR_HIDDEN flag. When set, this flag enables “low profile" mode for the system bar or navigation bar. Navigation buttons dim and other elements in the system bar also hide. Enabling this is useful for creating more immersive games without distraction for the system navigation buttons.
The SYSTEM_UI_FLAG_VISIBLE flag replaces the STATUS_BAR_VISIBLE flag to request the system bar or navigation bar be visible.
The SYSTEM_UI_FLAG_HIDE_NAVIGATION is a new flag that requests the navigation bar hide completely. Be aware that this works only for the navigation bar used by some handsets (it does not hide the system bar on tablets). The navigation bar returns to view as soon as the system receives user input. As such, this mode is useful primarily for video playback or other cases in which the whole screen is needed but user input is not required.
You can set each of these flags for the system bar and navigation bar by calling setSystemUiVisibility() on any view in your activity. The window manager combines (OR-together) all flags from all views in your window and apply them to the system UI as long as your window has input focus. When your window loses input focus (the user navigates away from your app, or a dialog appears), your flags cease to have effect. Similarly, if you remove those views from the view hierarchy their flags no longer apply.
To synchronize other events in your activity with visibility changes to the system UI (for example, hide the action bar or other UI controls when the system UI hides), you should register a View.OnSystemUiVisibilityChangeListener to be notified when the visibility of the system bar or navigation bar changes.
See the OverscanActivity class for a demonstration of different system UI options.

Say I have an app running, how would I go home or back without the nav bar? We have no physical buttons or capacitive buttons...
Sure some apps let you quit from the app itself but others don't.
Are u saying you would like to have it duck outta the screen?

It would be nice if it was sorta programed as it was on the GNex when in apps such as YouTube when viewing a video in full screen the buttons disappear (actually disappear not dim out) and when you touch the screen the buttons reappear.

The buttons don't disappear, they dim; if you touch them they come back
If anything, I would love to have the app drawer button on the nav bar

Yep agree... this thing with menu top right and notifications bottom left is nuts. Buttons should be near the bottom where I hold it. Ideally the menu buttons (Inc app drawer) would be bottom right and notification top right.
Actually all devices have power button which can be used for getting back from fullscreen mode.
There is an issue on code.google (24546): hxxp://code.google.com/p/android/issues/detail?id=24546
I think it's pretty nice solution. Also there can be "hide" button on panel.
Hi,
i would like to hide navigation bar so i can use PIE for navigation but the navigation bar showing up when swiping from the bottom. For me it is ok that i can show the status bar by swiping from top
So how can I disable navigation bar from showing up when i swipe, but let the status bar function by swiping from top to down when i want
Thanks a lot!
Semi immersive is great, it doesnt show the navigation bar when i swipe from bottom to show PIE, but it shows the status bar, is it possible that it show the status bar only when i swipe from top to bottom, not when i show PIE, i hope i explained it a lil bit better now
Is there a way to customize the navigation bar keys?
To set specific tasks for each press?
For example toggle flash light on long press recent apps button..?
There's this app called custom navigation bar which can do such stuffs and more even without requesting root:

But unfortunately it does not support EMUI
Any other solution?

I hide the nav bar with an app that gets the permission to hide it through adb (eg. Navigation Gestures app). So when I simply press “Hide navigation bar” in the Navigation Gestures app, the nav buttons disappear, but the invisible bar stays on. To remove the bar I first go to the phone’s settings, make the bar hideable there, hide it natively, then go to the Navigation Gestures app and hide the bar there. It’s now gone. But as soon as I make a swipe from the bottom of the screen, the invisible bar appears (without the buttons), pushing the icons up. It only happens on the home screen, not in any other apps.
As far as I understand it’s the phone’s launcher responsible for this behavior, it’s not a bug of the Navigation Gestures app (I tried two such apps). So can the nav bar be hidden completely with adb or otherwise?
How can I hide the notification and status bar and be in full screen ,I have the Chinese version
Go to settings>convenience aid>navigation keys>virtual keys enable virtual keys can be hidden. Or use swipe gestures instead.
