Not seeing any issues with the events. No warnings in console. Please provide details/sample code.

Correct test case

    var win=Ti.UI.createWindow({backgroundColor:'white', layout:'vertical'});
    var view= Ti.UI.createView({
        top: 0,
        bottom: 0,
        backgroundColor: "red",
        width: 50,
        height : 50,
        accessibilityLabel: 'Red view'
    });
   
   var btn1 = Ti.UI.createButton({
       title: 'Add',
       width:100,
       height: 100,
       accessibilityHint: 'This will add view on screen'
   
   });
   var btn2 = Ti.UI.createButton({
       title: 'Update',
       width:100,
       height: 100,
       accessibilityHint: 'This will update the button title'
   });
   
   btn1.addEventListener('click', function(e){
   	view.show();
        Ti.App.fireSystemEvent(Ti.App.iOS.EVENT_ACCESSIBILITY_SCREEN_CHANGED);
   });
   
   btn2.addEventListener('click', function(e){
   	btn2.title = "Updated";
       btn2.accessibilityHint = "This button has been already pressed.";
       Ti.App.fireSystemEvent(Ti.App.iOS.EVENT_ACCESSIBILITY_LAYOUT_CHANGED);
   });
   
   win.add(view);
   win.add(btn2);
   win.add(btn1);
   view.hide();
