In the GIF it looks like it’s working, though.

i made the button and its work for some move

Are there any errors in the output?

nope they no error , i dont want to make mobile player hold the button like just press 1 button the move activated

There’s a better way but I don’t know it, but here’s the simple way I guess:

local uis = game:GetService("UserInputService")

local button = script.Parent -- your button object

if uis.TouchEnabled then -- Checking if Touch Enabled if true then a mobile player is playing
	button.Visible = true
end
