Learn how to locate common Android hardware features, how to charge the device, turn the device on or off, lock the screen, unlock the screen, and power off an Android phone or tablet.
- [Instructor] All Android devices offer consistent and similar features, which provides you with an advantage. Once you learn these features, working with any Android phone or tablet is familiar to you. On the front of the gizmo, you're going to find the touch screen, which works as a display and as an input device reacting to your touches. Navigation buttons are found at the bottom of the touch screen. They may also be physical buttons located below the touch screen. Not readily visible is the front-facing camera, which is found right above the touch screen somewhere.
Android phones feature a speaker at the top center, which is where you place your ear during a call. Android tablets put their speakers on the left or right sides or the top or bottom sides, depending on the tablet. Around the edge of the device, you'll find several useful items. They may not match the specific locations shown here, but look for them anyway on your own device. You have the Power/Lock key, the Volume key, a headphone connector, which may not be at the bottom edge as shown here, the USB cable connector, and a microphone.
You might also find a microSD card slot for removable storage and a SIM card slot used on cellular devices to connect to the mobile data network. The back of the device features a rear camera. A flash LED can be found next to the camera, though not every Android tablet features a flash. To charge your Android's battery, connect the power cord to the USB connector on the bottom of the device. Connect the other end of the cable to a charging adapter, then you plug the adapter into a wall socket.
The phone or tablet charges whether it's on or off and you can use the device while it's charging. As a tip, you can charge it any time, you don't need to wait until the battery is completely drained to charge. To turn on your Android, press and hold the Power/Lock key. Keep holding it until you feel the device vibrate or you see a startup logo, at that point, release the Power/Lock key. As the device charges, you'll see some startup animation, it may be the Android logo, the manufacturer's logo, and you may hear some music or other sounds playing.
Once startup is complete, you may need to unlock the screen. If so, work the screen lock and the device continues to start. Eventually you see the home screen, which is where you can start using the phone or tablet. Your Android stays on most of the time. When you're done using it or you need to set it aside, you lock the screen. To do so, quickly press and release the Power/Lock key. When the device is locked, the touch screen goes dark and it no longer accepts input. The device continues to run, however, music will play, phone calls can come in, updates are made, and alarms will trigger.
The device saves power while it's locked, so your Android locks itself automatically after a given period of inactivity. This automatic locking is similar to Sleep Mode on a computer. To unlock your Android, quickly press and release the Power/Lock key. Swipe the screen and work the secure screen lock if one is applied. Some devices feature lock screen apps, such as the Camera app. Lock screen apps allow you to quickly unlock your Android and instantly run the app.
To do so, swipe the app launcher icon across the lock screen. You don't need to work the secure screen lock, the app just starts. Now, if you do need to access other places on the phone or tablet, you must work the secure screen lock to continue. It's rare that you need to turn off your Android. Most of the time, you just lock it. When you do need to turn off the Android, press and hold the Power/Lock key. When you see the device options menu, choose Power Off. You'll be prompted to confirm, tap the OK button if you are, and the Android turns itself off.
Turning the device off isn't the same as locking it. When the Android is off, it no longer works. It won't receive phone calls and alarms won't trigger. Remember, it's rare to turn off your Android. Most of the time, just lock it and you'll be fine.
