A new hands-on video displays Canonical's Ubuntu downloaded and running on the original Galaxy Nexus.
The video was taken at this year's Consumer Electronics Show in Las Vegas at the official Ubuntu booth by the tech blog YouMobile.org.
It gives views a first-hand look at the software's interface and featurers. The version in the video is still just a pre-release with the official one coming in April 2014.
The London-based operating system is being developed for smartphones by Canonical, whose founder Mark Shuttleworth recently announced that it should be available on phones and tablets by April 2014.
Shuttleworth also stated that the Ubuntu Phone OS has been designed from the ground up to offer a "crisper, sharper" experience on low-end phones.
He expects many low-end devices to adopt the software which has the ability to be in "lean mode," allowing it to run well on devices with lesser specifications.
The minimum specs for the software to run on will be an A9 ARM processor and 1GB RAM.
The software's "heavy mode" will be designed for high-end hardware and Shuttleworth's goal with it is to achieve a "less complex" user experience than that of the competition.
The devices released with Ubuntu pre-installed will feature most of the bells and whistles of traditional smartphones, but will function as a full PC when docked to a monitor, keyboard and mouse, according to a statement from Canonical.
"We expect Ubuntu to be popular in the enterprise market, enabling customers to provision a single secure device for all PC, thin client and phone functions," said the company's CEO Jane Silber in a statement. "We also see an opportunity in basic smartphones that are used for the phone, SMS, web and email where Ubuntu outperforms thanks to its native core apps and stylish presentation."
