So I’m using a 1st person lock LocalScript but I got a problem in cellphone where you cannot rotate your screen (So you can only look forward). I’m PC It does work correctly but in cellphone It doesn’t let you rotate your camera. Also this script is BIG so If you don’t have much time left to read this whole script I recommend you to not see it.
I know there’s a lot of good people here, and if you can give me a hand with this I’ll be very very grateful to you ! 
Here’s the full script:
repeat wait() until game:GetService("Players").LocalPlayer.Character ~= nil
local runService = game:GetService("RunService")
local input = game:GetService("UserInputService")

CanViewBody = true -- whether you see your body
Sensitivity = 0.1 -- anything higher would make looking up and down harder; recommend anything between 0~1
Smoothness = 0.05 -- recommend anything between 0~1
FieldOfView = 100 -- fov
HeadOffset = CFrame.new(0,0.7,0) -- how far your camera is from your head
local cam = game.Workspace.CurrentCamera
local player = players.LocalPlayer

local character = player.Character or player.CharacterAdded:wait()
local human = character.Humanoid
local humanoidpart = character.HumanoidRootPart
local head = character:WaitForChild("Head")
