Detect mouse movement in certain direction does not work correctly on mobile

Help and Feedback Scripting Support

--------------------This is in a localScript
local detect = script.Parent.detect --this goes to an imageButton that is the child of a surfaceGui that is attacted to a block

local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local mouseX

detect.MouseButton1Down:Connect(function()
	mouseX = mouse.X
end)

detect.MouseButton1Up:Connect(function()
	local diffX = mouseX - mouse.X
	if diffX > 80 or diffX < -80 then
		if diffX < 0 then			
			print("right")
			mouseX = nil
		elseif diffX >= 0 then			
			print("left")
			mouseX = nil
		end
	end
end)

This works fine on PC. But on mobile, this will work but if I try again in the same direction as the previous, it will not work. Another issue that only happens on mobile is I can just click on either side of the surfaceGui without dragging and it will still run.

You should set ‘mouseX’ to ‘mouse.X’ not ‘nil’.

Tried it and it didn’t change anything.

I tried putting a print in the mouseButton1Up function both before the first if statement and after. The first print before the if statement works. the one inside the if statement does not.
