Finding out how far a GUI from InputBegan has been dragged?

So I have been having trouble finding out how far a GUI button has been dragged

Here's what I tried to do

local ImageButton = script.Parent.ImageButton
local UserInputService = game:GetService("UserInputService")

ImageButton.InputBegan:Connect(function(InputObject)


    print(  UserInputService:GetMouseLocation())    

    print(InputObject.Position)

end)




UserInputService.InputBegan:Connect(function(InputObject)
    print(InputObject.Position)
end)

All of these print different positions which makes it very difficult to track how far a GUI has been dragged

I was planning on using UserInputService's InputChanged for this

Does anyone know how I can figure out how far a GUI has been dragged?

UserInputService.InputChanged:Connect(function(InputObject)
    -- Planned on Minusing from the InputBegan position to see how far it was but Input Began won't return reliable positions


end)

Also I know I am being a bit needy

BUT I DO NOT WANT ANY ANSWERS USING 1. A while True Do loop 2. :GetMouseLocation()

:GetMouseLocation() has an big issue with it's offset difference in Mobile and PC meaning

A PC position will be accurate however a Mobile has an

Offset which makes it so that it's innacurate

I don't know why
