On-screen navigation buttons on new Phones

[0vZ]

Hi guys!
Can you give me some info about on-screen navigation buttons (back, start, search) on new phones like lumia 630, 730, etc?
I want to know, how can I hide them? and how to check, if they exists?

I don't think you can show/hide them programatically using C# or VB. The user toggles them by swiping upwards from the bottom of the screen, similar to the Action Center. They take up the bottom 40px of the screen, so Lumias that have them have screens 40 pixels higher than the standart resolution but this doesn't apply for all phones. I couldn't find any API for it but there are only a few phones with on-screen buttons so you can check that until there is one.

As startrunner said there is no API currently to check this or control their visibility from within 3rd party apps. From a developer standpoint they function exactly the same as hardware buttons in terms of what event handlers to tie into.

You can hide the soft navigation bar programmatically, like this:

           Windows.UI.ViewManagement.ApplicationView.GetForCurrentView().SuppressSystemOverlays = true;

Note that this works when "Navigation Bar" is set to Auto in Phone Settings, which is the default.
