Hey! Is there a certain type of code where it only happens for certain devices?

I found this link on the devforum about an existing topic: https://devforum.roblox.com/t/how-to-detect-if-player-is-using-a-phone/178533

You can use UserInputService and GuiService to determine whether a player is on mobile or not.

local UIS = game:GetService("UserInputService")
local GServ = game:GetService("GuiService")
local te = UIS.TouchEnabled -- can you touch the screen?
local ke = UIS.KeyboardEnabled -- is there a keyboard?
local me = UIS.MouseEnabled -- is there a mouse?
local ge = UIS.GamepadEnabled -- is there a gamepad?
local tenfoot = GServ:IsTenFootInterface() -- is tenfootinterface enabled? (a roblox ui exclusive to console)
 if te and not ke and not me and not ge and not tenfoot then
     -- your code because its a mobile device
end

--[[
same thing with detecting consoles and pc's

if ke and me then
    pc
end

if tenfoot then
    console
end
]]

Hope this helps

There's no native way to get the user's device type. However, there are some functions that may interest you:

UserInputService.AccelerometerEnabled

UserInputService.GamepadEnabled

UserInputService.GyroscopeEnabled

UserInputService.KeyboardEnabled

UserInputService.MouseEnabled

UserInputService.TouchEnabled

UserInputService.VREnabled

GuiService::IsTenFootInterface

Mobile devices have MouseEnabled and KeyboardEnabled false. Most mobile devices should have an accelerometer and gyroscope.

Console devices have KeyboardEnabled false, and IsTenFootInterface true.

I may have missed some functions or properties from the wiki, but you can explore yourself.

Also, here's a snippet of code I found on the DevForums, I forgot who the original author was, so I apologize if it was your's.

local GuiService = game:GetService("GuiService")
local UserInputService = game:GetService("UserInputService")
function getplatform()
    if (GuiService:IsTenFootInterface()) then
        return "Console"
    elseif (UserInputService.TouchEnabled and not UserInputService.MouseEnabled) then
        --touchscreen computers now have touchenabled so make sure to check for lack of mouse too
        --also, not all phones/tablets have accelerometer and/or gyroscope
        local DeviceSize = workspace.CurrentCamera.ViewportSize; 
        if ( DeviceSize.Y > 600 ) then
            return "Mobile (tablet)"
        else
            return "Mobile (phone)"
        end
    else
        return "Desktop"
    end
end
