You can try with the following options:
Code:
mobile_emulation = {
"deviceMetrics": {"width": 360, "height": 640, "pixelRatio": 3.0},
"userAgent": "Mozilla/5.0 (Linux; Android 4.2.1; en-us; Nexus 5 Build/JOP40D) AppleWebKit/535.19 (KHTML, like Gecko) Chrome/18.0.1025.166 Mobile Safari/535.19"
}
chrome_options = Options()
chrome_options.add_experimental_option("mobileEmulation", mobile_emulation)
Basically, you have to change the width & height as well as the pixelRatio & use a real phone user useragent,
The above is set to match a Nexus 5, you can change it to whatever you want, just make sure to set the other values to match as well
