An Android is a complex piece of electronics: delightful, inspirational, intimidating. Obviously, that qualifies an Android phone or tablet as the next great thing. It also means that if you want to get the most from the device, you need some gentle hand-holding and careful explanation.

This Cheat Sheet provides that information, plus plenty of tips and tricks and other useful information that help make your Android mobile device experience a pleasant and productive one.

Android Home Screen

The main screen on an Android is called the Home screen. It’s where all the action takes place: where you start the apps, work the widgets, and check out what’s going on via notification and status icons.

You find several Home screen pages, some marching off to the left and others marching to the right, for a total of anywhere up to nine Home screen pages, depending on the device. Each Home screen page can be adorned with icons, widgets, and sneeze globs. Only the sneeze globs are easily removed by using a microfiber cloth.

Android Navigation Icons

Androids feature common methods of using the Home screen as well as various apps. The two forms of navigation are gesture navigation and the traditional navigation icons found at the bottom of the touchscreen and illustrated nearby.

Gesture Method Icon Function
Back Swipe the screen inward from the outer left or right edge.
Go back, close, or dismiss the onscreen keyboard.
Home Swipe up the screen from the bottom.
Go to the Home screen.
Recent Swipe up the screen, but pause about one-third of the way.
Display recently opened apps.

Common Android Icons

Various icons appear while you use your Android mobile device. These icons serve common functions in your apps as well as in the Android operating system. Common icons and their functions are shown here:

Icon Name Function
Action Overflow Displays a list of actions, similar to a menu.
Add Adds or creates an item. The plus symbol (+) may be used in combination with other symbols, depending on the app.
Chevron Pointing in various directions, expands or collapses a card, menu, or other item.
Close Dismisses a card, clears text from an input field, or removes an item from a list.
Delete Removes one or more items from a list or deletes a message.
Dictation Activates voice input.
Done Dismisses an action bar or confirms and saves edits.
Edit Lets you edit an item, add text, or fill in fields.

Search Searches the screen, tablet, or the Internet for a tidbit of information.
Settings Adjusts options for an app.
Share Shares information via a specific app, such as Gmail or Facebook.
Side Menu Also called the hamburger, lets you view the navigation drawer available in most Android apps.

Android Touchscreen Operations

It takes a certain finesse to work a touchscreen. Here are some of the common operations you can perform using your fingers on an Android’s touchscreen:

Action How It’s Done
Tap The basic touchscreen technique is to touch it. You tap an object, an icon, a control, a menu item, a doodad, and so on. The tap operation is similar to a mouse click on a computer. It may also be referred to as a touch or a press.
Double-tap Tap the screen twice in the same location. A double-tap can be used to zoom in on an image or a map, but it can also zoom out. Because of the double-tap’s dual nature, I recommend using the pinch and spread operations to zoom.
Long-press Tap part of the screen and keep your finger down. Depending on what you’re doing, a pop-up or card may appear, or the item you’re long-pressing may get “picked up” so that you can drag (move) it around. Long-press might also be referred to as tap and hold.
Swipe To swipe, tap your finger on one spot and then move your finger to another spot. Swipes can go up, down, left, or right; the touchscreen content moves in the direction in which you swipe your finger, similar to the way scrolling works on a computer. A swipe can be fast or slow. It’s also called a flick or slide.
Drag A combination of long-press and then swipe, the drag operation moves items on the screen. Start with the long-press, and then keep your finger on the screen to swipe. Lift your finger to complete the action.
Pinch A pinch involves two fingers, which start out separated and then are brought together. The effect is used to zoom out, to reduce the size of an image, or to see more of a map. This move may also be called a pinch close.
Spread In the opposite of pinch, you start out with your fingers together and then spread them. The spread is used to zoom in, to enlarge an image or see more detail on a map. It’s also known as a pinch open.
Rotate Use two fingers to twist around a central point on the touchscreen, which has the effect of rotating an object on the screen. If you have trouble with this operation, pretend that you’re turning the dial on a safe.

Android Tricks to Remember
