If you use the previously installed Internet browser on your Samsung Galaxy S9, you may notice that this website does not display in a mobile optimized view. T
his means that the page is very small and displayed in full width and size.
The background for this is that the "desktop view" is activated in the Internet browser settings.
This means that the visited website is displayed as if you were accessing it from a desktop computer.
This sometimes has the advantage that you can navigate better. How to activate the "mobile view" again on the Samsung Galaxy S9 is described briefly here:
1. Open the browser "Internet"
2. Tap on the symbol with the three dots in the upper right corner --> Select "Request mobile website"
Then the mobile view of the website is requested again by your Samsung Galaxy S9, which is now displayed to you in a so-called "responsive design".
