Uhm, there won't be a point, since what an SIII sees, a One X sees the same way. All Android devices work that way. Basically it just tells the site that what type of device accesses it and it displays the corresponding version of the website. Using an iPhone UA shows the iOS version, using an Android UA will show the Android version of the site, regardless of it being an SIII or OneX. Both will see the same thing.
