If waiting for the Android L release to land is already getting to you, we have some soothing news. Developers, given the early release, have dumped the backgrounds online for all to have.
As is typical with any new mobile operating system from Android there is usually a set of unique wallpapers that suit that release. Android L is no exception. In fact with its new shadow laden Material look there are plenty to choose from.
You can either save them from the gallery as smaller versions below or use this Dropbox link to download them all directly to your mobile from here.
Of course this is just a temporary stop gap. The real full Android L release, which will likely be called Lollipop, won't be out until later this year. So, you know, make these last.
