To serve better user experience, FaceBook rolled out a major upgrade to its Mobile site m.facebook.com that delivers the best possible mobile Web experience no matter what device you’re using.
Lee Byron, Interactive Information Designer at Facebook stated “With the new m.facebook.com, users with high-end touch devices will see a rich touch-friendly interface; for users with feature phones, the site will look and work great,”
Earilier, Facebook has multiple versions of its mobile site, touch.facebook.com for touch devices, and m.facebook.com for less feature-rich mobile devices. The mobile web for touch device which adapts on the device hardware capabilities like a phone with no GPS will not see the Places Check-in feature. Feature phone users will see a scaled-down version of the mobile site, with an interface adapted for their screens.
With the new m.facebook.com, users with high-end touch devices will see a rich touch-friendly interface; for users with feature phones, the site will look and work great.
Every device uses the same framework. This way we can move even faster and build new features just once for every mobile device. It also means that everyone can access the same features, whether writing messages or checking into Places. There will no longer be a difference between m.facebook.com and touch.facebook.com, we’ll automatically serve you the best version of the site for your device.
The new site is powered by a UI framework based on XHP, Javelin, and WURFL, a detailed database mapping user agents to device capabilities. This enables us to very precisely target experiences and features to thousands of different devices. The 0.facebook.com site also uses the same codebase as m.facebook.com.
