Google's Ice Cream Sandwich, Android 4.0, is the biggest update the popular smartphone platform has received in more than a year. It adds dozens of features, changes and improves the interface, and makes much better use of the latest smartphone hardware. It may finally make Android tablets viable, too. At launch, though, it's missing a few things, most notably Flash and Facebook support, which mean that you may do well waiting a few months before scooping out some Ice Cream for yourself.
The New UI
The new Ice Cream Sandwich UI integrates elements from the Gingerbread phone and Honeycomb tablet UIs into, hopefully, a harmonious system which will work equally well on phones and tablets.
The look employs a lot of subtle shading, a lot of compositing, and a lot of depth, especially compared to the very flat screens in Gingerbread. Powerful GPUs seem to be assumed here, as screens and images almost always have multiple layers. But a generally spare design keeps it feeling like Android: functional, not showy.
The new lock screen shows the date, time, and your wallpaper. To unlock the phone, swipe right, or swipe left to jump directly to the camera. That takes you to one of five home screens, where you can place widgets or icons at will. You can now create folders on your home screens, and the folder layout is witty and smart: it shows the icons of various items in the folder, stacked. Four favorite icons, now customizable, stay at the bottom of every home screen.
The app drawer is still there, but now it's two-paned: you can flip between apps and a full-screen display of available widgets. Sliding between pages of apps, it looks like each one reveals the next under it. The multitasking interface borrows from Honeycomb: press a dedicated "multitasking" soft key, and thumbnails of the last several apps you've used ghost above the display. (There's that multi-layer compositing again.)
