Original Story: The long rollout for the Lumia Denim firmware update continues as Microsoft's support page has confirmed it is now available on more devices in the UK. Specifically, O2 owners of the Lumia 635, Lumia 930 and Lumia 1520 can now download Denim, along with owners of the unlocked country variant for the 1520.
Once updated, owners of supported phones should be able to use the new Lumia Camera 5.0 app with 4K video, Rich Capture, and faster startup times, along other many new features. As always, it may take a few days for the over-the-air Denim update to reach all of the devices.
Thanks to the many folks that tipped us!
