The Browser UA allows the server to identify the operating system and version used by the client, the CPU type, browser and version, the browser rendering engine, the browser language, and the browser plug-in to determine whether the user is browsing from a computer or a phone. The website is then able to adjust the layout of the web page according to the corresponding format so as to improve the browsing experience.

Go to Browser > Settings > Browsing Settings > Browser UA, and select an option. In general, it is recommended that you select Android (default).
