title: Python and Selenium mobile emulation
body: <p>I'm trying to emulate Chrome for iPhone X with Selenium emulation and Python, as follow:</p>
  
  <pre><code>from selenium import webdriver
  
  mobile_emulation = { "deviceName": "iphone X" }
  
  chrome_options = webdriver.ChromeOptions()
  
  chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
  
  driver = webdriver.Chrome(r'C:\Users\Alex\PythonDev\chromedriver')
  
  driver.get('https://www.google.com')
  </code></pre>
  
  <p>However, nothing happens: my page is still a normal browser page, and I don't see it as a mobile page.</p>
  
  <p>What is missing or wrong in my code?</p>
