Ice Cream Sandwich: What to expect from Android 4.0

— -- The term Ice Cream Sandwich may bring to mind a tasty frozen treat, but Ice Cream Sandwich is also the latest version of Google's mobile operating system, Android. Android is used on both mobile phones and tablets, and Ice Cream Sandwich (Android 4.0) is the first version of Android to be optimized for both.

Why is it called Ice Cream Sandwich?

Google has named each version of Android after a dessert item, in alphabetical order. There was once a version of Android named Cupcake and later versions named Donut and Eclair. A few phones sold on the market today are still running Froyo, and Gingerbread is currently used on the majority of new Android phones. The version known as Honeycomb was designed for and is used on many new Android tablets.

Why would I want Ice Cream Sandwich?

Ice Cream Sandwich is a big deal, and it differs from every Android operating system before it. Ice Cream Sandwich blends parts of Gingerbread and parts of Honeycomb into a single version of Android that can be used on both tablets and smartphones.

Android owners have long been plagued by something called fragmentation. With fragmentation, software that is written for one version of Android might not look so hot or work the way you expect it to on a device running another version of the OS. With different manufacturers releasing phones with a wide range of specs and custom software, it can be hard for developers to create apps that work for all phones and for phone makers to create phones that can be easily updated to new versions of Android.

Ice Cream Sandwich is expected to unify Android as a whole and set a few norms that should make the updating and development processes a little easier. The OS also offers quite a few new innovative features that are well worth a look.

Visual updates: If you're already an Android user, then Ice Cream Sandwich is going to look a lot different than what you've become accustomed to over the years. Google has completely overhauled the OS to make it more user-friendly, giving the entire operating system a new modern font and a magazine-like feel.

Improved camera: The camera app in Ice Cream Sandwich comes with a number of built-in photo editing features, so you can adjust your pictures directly on your phone. Improvements include basic things like red-eye reduction, cropping and straightening, and Hipster filters that add Instagram-like effects to your photos. The camera also has a single-motion panoramic mode, allowing you to take panoramic shots quickly and easily.

Voice typing: Android has had voice recognition capabilities for a while now, but Ice Cream Sandwich takes things a bit further by allowing you to say what you want to type. The feature will likely come in handy when you need to send a message while driving or when you need to keep your hands elsewhere.

Improved contacts and voicemail: Ice Cream Sandwich improves how Android displays your contacts with the People app. The app lets you see at a glance how you're connected to someone, as well as check out that person's latest moves on social networking sites. The OS also integrates visual voicemail, which lets you view and play each of your voicemails individually rather than having to listen to all of your messages at once. Voicemail can be sped up or slowed down while you're listening.
