Try to keep android L talk in this thread to avoid confusion
Is this discussion about Android L only, if so why is it in the 'Sony Xperia Z1' section of the forums?
As you see in this thread you have a chap posting images of the Android L on a Nexus 7 when this is a Sony Xperia Z1 section forums.
Sony's implementation will look nothing like the vanilla Android L.
I am sure there is a sub forum just for Android L chatter irrespective of what device you have outside of the 'Sony Xperia Z1' forum.
