The captured webpage is different from a real phone simulates the capture of mobile phone viewport when using the viewport feature.

Sometimes it doesn’t render like on a real mobile phone because the websites are not responsive the viewport sizes but try to detect if the device is a mobile phone or not. For these sites, what you see in the browser and what is captured by is different from what you would have in a real phone.

Most of these sites use the user-agent information to detect mobile device. You can change the user-agent of the browser to fix the problem.

How capture a mobile version of the website with a custom user-agent

1. Install our Chrome extension

If you haven’t already, go to our Chrome extension page and click on Add to Chrome.

2. Follow the same steps as capturing a mobile version
