Ubuntu Announces Its Phone Interface

Canonical demonstrated Ubuntu for Phones in early 2013 as an attempt to extend Ubuntu from PCs and servers into smartphones. The interface emphasized edge gestures: swiping from different sides of the screen opened applications, controls, or navigation.

Canonical wanted one underlying Ubuntu platform to span phones, tablets, and desktops. The long-term vision included “convergence,” where a phone connected to a monitor and keyboard could behave like a desktop computer. Applications were encouraged to adapt to different screen sizes rather than exist as completely separate mobile versions.

The project never achieved enough hardware and application support to compete with Android and iOS. Canonical ended its phone effort in 2017, but the convergence idea survived elsewhere as modern phones became powerful enough to drive desktop-style interfaces.
