How to Make a Folder
To create a folder, long-press an app. Press and hold a finger on the app until you feel a mild feedback vibration and the screen changes. Then, drag the app onto another app to make a folder. This is the same as on iOS devices such as the iPad and iPhone.
Name Your Folder
Unlike iOS, Android doesn’t provide a default name for new folders; it appears as an unnamed folder. When a folder is unnamed, nothing displays as the name of the collection of apps. To give the folder a name, long-press the folder. It opens, displays the apps, and launches the Android keyboard. Enter a name for the folder and tap the Done key. The name displays on the Home screen.
Add Your Folder to the Home Row
You can also drag the folder onto your favorite apps on the bottom of the Home screen on Android phones. That makes it two clicks to get to the app, but Google demonstrates this by grouping Google apps into a folder and putting it on the Home row at the bottom.
Some Things Do Not Drag Like the Others
Dragging order is important. You can drag apps onto other apps to make folders. You can drag apps into existing folders to add the app to the folder. You cannot drag folders onto apps. If an app runs away when you drag something on it, that could be what happened. The other thing you can’t do is drag Home screen widgets into folders. Widgets are mini apps that run continuously on the Home screen, and won’t run properly inside a folder.
