Security and apps

a touchscreen device that uses fingerprint recognition security

Security

In this activity, you will read about how to use apps, see notifications, and we'll look at some security options.

If you have a touchscreen device of your own, then you probably want to make sure it's secure. Some devices have a fingerprint security option. When you turn this on you scan your fingerprint and then use that to unlock your screen every time you use it.

Launch lesson

If you don’t have a fingerprint option, you can still set an unlock code number, known as a passcode or Personal Identification Number (PIN for short), or even a pattern. These are then requested every time the screen is used.

To set any of these security features you need to find the 'Settings' options.

The Settings options can be different depending on which device you’re using, but they all do similar things.

Applications or Apps

One of the great things with touchscreen computers is how easy it is to get software for particular tasks. These software programs are called applications, or apps for short.

Your device will already have a place to get or purchase apps. It might be called ‘App store’, ‘Google play’ or 'Windows Marketplace', depending on the type of touchscreen device you own.

Apps

Apps - short for applications - are programs that you can install or delete from your device. Your device will probably have apps that come with the device and you don't need to install them. On your device, you'll find such apps as Calendar, Contacts, Maps, Clock and others. You don't need to pay for them and they're ready to be used right away.

You can also get apps to play games, connect with people you know, edit pictures and probably every other task you can think of to do on a computer. Such apps aren't always free and you'll need to be careful before installing an app.

How to get apps

You'll find lots of free apps but there are also lots that you need to pay for.

Often, paid apps have more features but it’s best to check that you really need them before you buy them.

Check apps before you buy

Always check reviews and ratings for apps, especially for apps that you need to pay for.

Checking what other people think can be a good way of finding out if you'd be better off with a free app or paying for one.

Check who created the app

Look at who has created the app too. If an app is for a major company, like your bank, it's probably going to have been created by them too.

Lots of smaller companies create apps, but ones from companies you've heard of are likely to be safe and easy to use.

eSafety Tip

Do a little research into an app before downloading it - don't download just any app. Ensure you're downloading phone or tablet applications from reputable, trusted sources. Read the reviews before downloading an app.

Notifications

Apps can make using your touchscreen easier. One of the ways they do this is with notifications.

Notifications on touchscreen devices can vary depending on the device.

One of the most common notification methods is for a small symbol to be displayed at the top of the screen.

On most devices, you will be able to use the swipe motion, by placing your thumb or finger at the top of the screen and dragging down, to show all of your notifications.

Next, you’ll be able to tap any of them to see more details about that notification.

Home button

Most mobile devices have a 'Home button'. This can vary depending on which device you're using. The Home button is good to get back to the main screen of the touchscreen.

On an Apple device, the Home button is a circular button below or to the side of the screen. On an Android device it’s also a small circle but this time, it’s on the screen itself.

Too many apps

When you're using a touchscreen, if you have too many apps running at the same time it can start to slow things down. You can avoid this by closing apps when you're not using them.

The procedure for closing apps is different depending on the device you are using.

To close an app in Windows devices, long tap on the app and drag it to the bottom of the screen. Let go to close the app.

Closing the app in Apple devices

Quickly press the home button twice. Find the app you want to close and swipe up. This app will disappear from the screen.

Closing the app in Android devices

Tap the small square at the bottom of the screen. This will show you all the apps that are currently open. Long tap an app and swipe to the side. Letting go will close the app.

Hamburger menu

Most touchscreen devices have smaller screens than laptops and desktop computers, and so many websites hide their menus to help reduce the amount of content on the small screen.

Most websites use a small image of three horizontal lines to show that there's a hidden menu. This image is sometimes referred to as the 'Hamburger menu', as it looks a bit like a hamburger. Tapping this hamburger symbol, or icon, will open the hidden menu.
