When discuzX3 is enabled for the mobile phone version, the website will automatically determine whether it is from the desktop or mobile end. How can this problem be solved?

Is it in PHP or webserver? Is it in index. php? The host is processed before this file, but the logic related to useragent is not seen. I would like to know where discuzX3 is and how to judge it? Thank you ~ Is it in PHP or in web server?

No user agent-related logic is found.

You did not find it!
