Showing Secondary ToolBar items - best way?

I use two devices for testing my app:

1. Phone(Android 4.0.3). It has a hardware button menu
2. Tablet(Android 4.2.2). It has no hardware button menu.

This is code my ToolBars

  <ToolbarItems >  
    <ToolbarItem Text="Action1"  Order="Primary" />
    <ToolbarItem Text="Action2"  Order="Secondary" />
    <ToolbarItem Text="Action3"  Order="Secondary" />
 </ToolbarItems>

When I run app on the phone button with secondary items not showing.

I need to press the menu button that would showing secondary items.
When I run app on the tablet button with secondary items showing. This is normal?
I tried to use this code:

           ViewConfiguration config = ViewConfiguration.Get(this);
            Field menuKeyField = config.Class.GetDeclaredField("sHasPermanentMenuKey");

            if (menuKeyField != null)
            {
                menuKeyField.Accessible = true;
                menuKeyField.SetBoolean(config, false);
            }

I first run app on the phone button with secondary items not showing. Second and other run - button with secondary items showing.
But this hack. The default behavior of the application is that normal? What do you do in this case?
