How does iphone switch between computer version and mobile version?

Hello, my 4S has also entered the default mobile version of Baidu.

This is because Baidu has the function of automatic identification code and will give priority to the user's equipment needs. The two versions at the bottom of Baidu switch randomly. When you say switch back to the webpage, you mean go to another website. However, some websites only have WWW domain name sites, which can only be viewed in the computer version mode, and some only have WAP or 3G sites, so the computer version does not exist. If it is to save traffic, then I suggest that some third-party browsers complement Safari. For example, the Dolphin browser can enter common websites by voice Baidu search or gesture, and UC can go to the map and compress it into a mobile version of the webpage. You can try.

I hope I can help you.
