When it comes to tablets, Google doesn't even follow its own design guidelines." That's the upshot of Ars Technica writer Andew Cunningham's detailed, illustrated look at how Android handles screens much larger than seven inches, going back to the first large Android tablets a few years ago, but including Android 5.0 (Lollipop) on the Nexus 10 and similar sized devices. Cunningham is unimpressed with the use of space for both practical and aesthetic reasons, and says that problems crop up areas that are purely under Google's control, like control panels and default apps, as well as (more understandably) in third party apps. The Nexus 10 took 10-inch tablets back to the "blown-up phone" version of the UI, where buttons and other UI stuff was all put in the center of the screen. This makes using a 10-inch tablet the same as using a 7-inch tablet or a phone, which is good for consistency, but in retrospect it was a big step backward for widescreen tablets. The old interface put everything at the edges of the screen where your thumbs could easily reach them. The new one often requires the pointer finger of one of your hands or some serious thumb-stretching. ... If anything, Lollipop takes another step backward here. You used to be able to swipe down on the left side of the screen to see your notifications and the right side of the screen to see the Quick Settings, and now those two menus have been unified and placed right in the center of the screen. The Nexus 10 is the most comfortable to use if it's lying flat on a table or stand and Lollipop does nothing to help you out there.
