The images, which are now based on the 13.04 Raring Ringtail codebase, are available on isotracker. As of now there are four devices that are supported and there is an image for each one of them – Nexus 7, Galaxy Nexus, Nexus 4 and Nexus 10. Instructions to install Ubuntu Touch have also been provided but, we recommend that only power users try their hands on the mobile OS.

Announcing the release Nicholas Skaggs, software engineer and quality assurance community coordinator wrote, “I’m happy to announce the Ubuntu touch images are now available for testing on the isotracker.”

“As such, the Ubuntu Touch team is asking for folks to try out the new images on their devices and ensure there are no regressions or other issues”, he added.

Skaggs added that the Raring Ringtail based images will become default once all the bugs and issues have been resolved. He also added that the team behind Touch will be providing daily images and will also participate in testing at a later stage.

Even though Canonical hasn’t released official images except for the four devices listed above, developers have been busy porting the OS to multiple other devices and the entire list is available here.
