If you've still got a Sony Xperia Z1 collecting dust in a drawer, or a OnePlus One that you just couldn't learn to love, then good news as now you can turn them into something new.
Canonical, the company behind open source Linux distribution Ubuntu has announced that its mobile operating system has been ported by the OS's community to work on both the Sony Xperia Z1 (first released in 2013) and the OnePlus One (which made waves in 2014). It is showing both these phones running Ubuntu off at Mobile World Congress, which is currently taking place in Barcelona.
So if you want something new to play with, with a whole new suite of apps, it might be worth a try. Ubuntu OS goes heavy on multitasking, allowing you to run mobile and tablet apps side-by-side, and you can even resize them if you like. Plus there's built in support for Facebook and YouTube - so even if it has fewer apps than Android, you'll have at least a couple of the essentials.
Though be warned: Installation isn't for the faint-hearted. To install it on your phone you'll need to be running Ubuntu on a desktop computer already - and then you'll need to carefully follow instructions on the command line. [Via Slashgear]
