The first mobile phone running the Ubuntu operating system will be released next week.

The phone will be made by Spanish company BQ, and is an adaptation of a phone that normally runs Android.

Instead it will run the Ubuntu Phone operating system. That is a re-purposed version of Ubuntu, the free and open source Linux operating system, that has been shrunk down for phones.

The operating system’s features include the fact that it has no lock screen. Applications will unlocked when needed, and the screen instead shows a circle in the middle that visualises what’s happening on the device.

The operating system includes common applications like Facebook and YouTube, and built in utilities like a calculator and email.

But as well as the operating system and the mid-level specifications — which allow the phone to be sold for only €169.90 — the company hopes to drive interest by offering the phone through a number of flash sales.
