Android L is available now if you have a Nexus 5 or a 2013 edition of the Nexus 7 – you don't need to sign up for an expensive developer account or anything like that. We've installed it on the Nexus 5 and left our Nexus 7 on Android 4.4.4 KitKat so you can see the differences. Also see: Android L offers remarkable battery life, but it's no faster than KitKat

Google has somewhat gone to town with Android L using a new design language called 'material design' which uses a new colour pallet while focusing on depth. Android L is also littered with new animations giving a more fluid feel.

Watch the video to see the new look and feel of the lockscreen, homescreen, notification bar, settings menu, navigation buttons, recent apps and more. It looks pretty different to the current KitKat interface.

There's also enhanced notifications, performance and battery life. Some things we can't show you in the video are the new Android runtime (ART), the 5,000 new APIs and Project Volta (battery performance). Google says the new battery saver mode and other tweaks will boost the battery life of the Nexus 5 by 90 minutes.
