Force chrome mobile browser to view mobile websites I am using chrome browser on a 5.5-inch smartphone. I notice that for phones with big screen, the website defaults to the desktop version. This goes the same for tablets. However, I will prefer to view the mobile website version on these devices. How can this be done?
I Think there is no problem with your phone. The problem is with the Website. Now a days websites are following 'Responsive web design' means 'Websites' automatically rescale/resizes(looks bigger or smaller)  themselves in respect to screen sizes of the viewing device which  depends on the website developer. 
I checked "www.economist.com" website.It only have desktop version so your phone display that desktop version. 
 You can't view mobile version because there is no Mobile version of the site . Be happy :)
