Android 4.0 makes it easy for you to create folders on your home screen that contain apps, in case you want to group similar items together to save on space or make things more tidy. While previous versions of Android had folders, they're easier to manage in 4.0, and their appearance has a sleek new look as well.
Android 4.0 makes it easy to create folders of applications on your home screen (left). Tap a folder to expand it and see what's inside (right). Click to view larger image.
To create a folder in ICS, all you do is drop one icon on top of another on your home screen. You can add more items into the folder the same way.
Once a folder's been created, you can tap the folder to open it and show all the apps within; you can remove any item from the folder by touching it and dragging it out. You can name the folder, too: Just touch your finger to the text that says "Unnamed Folder" and type in any name you want.
Finally, you can place any items you want in the Favorites tray below the home-screen panels so they'll always be handy: Just touch and hold any icon that's already in the tray to move it out, and touch and drag any other icon in to replace it. You can even create folders within the tray, if you're so inclined.
Working with widgets
We can't talk about Android apps without talking about widgets. Widgets are one of the most powerful features Android provides; they essentially give you live, functioning programs right on your phone's home screen. Widgets let you do things like scroll through your inbox or your calendar, flip through current forecasts for multiple cities, and adjust your phone's basic settings without ever having to open a program or leave the home screen.
Many widgets can be resized in Android 4.0. Click to view larger image.
Widgets are frequently included as components of applications. For example, if you download the Pandora app, you'll also get the Pandora widget, which you can put on your home screen (or not) as you like. Some developers also offer standalone widget downloads, like the popular Beautiful Widgets and HD Widgets collections.
You can see a list of widgets on your device by touching the Widgets tab at the top of the app drawer and swiping left or right through the list. Placing a widget on your home screen is no different than placing an app shortcut: You press and hold the widget you want, then drag it wherever you wish on your home screen.
