In this article you will learn how to effectively protect your Android tablet or phone.

Even though Android is the most popular and the best mobile platform, many specialists don't regard it as the most secure one.

That's why security of Android devices is not an issue we should neglect.

In this article, you will discover  5 essential ways in which you can protect your Android device and data contained on it.

Why is security of Android devices so imporant?

Before we begin to discuss ways to ensure security of our Android device, I want to explain why Android security is such an important issue which by any means shouldn't be neglected.

Android phones and tablets are the most technologically advanced devices on the market. They are used to facilitate every aspect of our lives and most people don't part with their phones ever for a minute. Our Droids are a source of the most sensitive personal data such as:

  • logins and passwords to various e-mail accounts and social networking sites
  • financial information
  • personal photos and videos
  • personal correspondence (SMS, MMS and e-mail messages)

That's why if we don't apply the below-mentioned methods, we will put all of these data at risk.

Use Some Android Security Apps

In the Google Play and Amazon, there are many security apps for Android. It's enough if you use one or two but don't neglect this. I recommend using one antivirus app and one app for protecting your phone and data from unauthorized use (the most popular and the best one is Lookout).

To choose Android security apps for your device, read the article about the best Android antivirus app and the best Android security app.

Lock Your Android Device

If you don't lock your Android device, you  provide access to data and information contained on it to anyone. Fortunately, Android provides three kinds of security lock. You can protect your device with PIN, Face Unlock or Pattern.

In practice, PIN works best because Face Unlock will very often fail to recognize you and Pattern (if you lock and unlock your device often) will simply remain on the screen until you wipe it off manually.

If you don't want to enter PIN every time you want to unlock your Android phone, you can use the option of automatically locking phone after, for example, 5 minutes.  To set a screen lock, go to Settings > Security and then choose PIN, Pattern or Face Unlock.

Consider Using Encryption

A great advantage of Android devices is the possibility of encrypting all your data on phone storage. This basically allows you to protect your device from anyone's reading what's on it.

Once you encrypt your Android device, you will have to enter a numeric PIN or a password each time you power it on. To activate phone storage encryption, go to Settings > Storage > Phone Storage Encryption.

Check App Permissions

Each time you install a new app from Google Play, you will see a pop-up window with app permissions (e.g. whether app has access to your personal information, your location, phone calls and so on). Always read this information especially if you install an unknown app.

Don't Download Apps or Games from Unknown Sources

This the rule no. one when it comes to Android security. There are many apps (hundreds of millions) in two biggest sources, that is, Google Play and Amazon so there is no need to risk by downloading apps from unknown and insecure websites.

Remember that all the Android apps and games I talk about on this site come either from Google Play or Amazon.
