Windows Phone 8: How to find the App list
All of the apps on your phone can be found in the App list—just flick left from the Start screen to go there. You can pan up or down in the App list to see your installed apps, or tap a letter to jump to a section of the alphabet.
Your apps don’t need to stay put on the App list, of course. You can tap and hold any app to pin it to Start or to uninstall it.
The App list is also the place where you can check the status of an app download or installation. If there’s a problem with an app, you can usually tap Attention required below the app name to get more information.
Note: Games don’t appear in the App list. They’re grouped together in the Games Hub, so it’s easy to browse your collection.
