Godot 4.7.2

ScrollContainer fails to scroll on Android when “Emulate Mouse From Touch” is unchecked.

I have created a project with all settings to default, added the Android export, and a single scene with

ScrollContainer → VBoxContainer → +50 Labels

I have used the “Deploy with Remote Debug”, then “Remove Deploy”, then a physical phone.

The ScrollContainer only scrolls when “Emulate Mouse From Touch” is checked.

If unckecked, the scrollbar appears correctly, but any attempts to scroll fail. The ScrollContainer is frozen.

I have attached the following script to the scene…

func _ready()


    %ScrollContainer.scroll_started.connect(_on_scroll_started)

    %ScrollContainer.scroll_ended.connect(_on_scroll_ended)

func _on_scroll_started() -> void:

    print("SCROLL STARTED")

func _on_scroll_ended() -> void:

    print(""SCROLL ENDED")

… and, indeed, nothing is printed.

I would like to understand why.

Is this intended? Is it a bug? Why does Android need “Mouse From Touch” checked for this specific type of control to work properly?

Thank you all.

Looks like a bug, open an issue in the issue tracker if there isn’t one already opened.
