Android Security in 2023: How to Protect Your Android Device

Android devices have become an integral part of our daily lives. Millions of Android users rely on their devices for communication, production, and entertainment. Yet, many people throw caution to the wind when it comes to keeping their smartphones or tablets safe and secure. Keeping any internet-ready device locked down is essential, and this article will explore the best practices and tools that will help ensure your device remains protected and your data stays private.

Security should always be a top priority regarding your Android device. We not only use our smartphones and tablets for playing games, checking out an odds calculator, and sending text messages to our friends but also for sensitive things like online banking and paying our tax bills. Android security is not only about protecting your device from outside threats but also about safeguarding your privacy.

Keep Your Android Software and Apps Up To Date

Staying up-to-date with software updates is one of the most crucial steps in ensuring your Android device’s security. It does not matter if you use a top-of-the-range Google Pixel 8 or a more budget-friendly device; keeping its inner workings patched up with the latest software update is essential.

Although software updates can occasionally disrupt your phone or tablet usage (have you noticed they seem to happen when you are busy?), they often contain security fixes and close potential loopholes that cybercriminals could previously take advantage of.

Keeping your applications up-to-date is equally important. While most updates fix minor bugs or improve the app’s look, developers work countless hours behind the scenes, ensuring their apps cannot be hacked or controlled by an external source. They release security updates that you should never ignore.

Also, be cautious about where you download your apps. It is possible to “side load” apps onto an Android device, but you should stick to downloading them from the Google Play Store, which has strict security measures in place to verify the legitimacy of apps.

Use Strong Authentication Methods and Check App Permissions

Anyone who regularly accesses the internet knows the importance of a strong password for logging into apps and websites. However, you should also set up robust authentication methods, such as fingerprint or facial recognition and two-factor authentication (2FA). Securing your device with biometrics ensures nobody, but you can access your data if your phone or tablet is lost or stolen. 2FA sends an email or text message when you log into an account, again adding a layer of security.

How many people reading this article have downloaded an app from the Google Play Store or anywhere else and clicked install without reading the privacy settings or the app permissions you are granting to the app? While most apps are legitimate and only want access to parts of your Android phone that are necessary for it to work, some request permissions they do not need. For example, ask yourself why a price comparison app requires access to your phone’s microphone or why a photo editing app claims to need your contacts to operate. You should regularly review your installed apps’ privacy settings and permissions and adjust them to ensure they only have access to the bare minimum required to work.

Safe Browsing Practices, Public Wi-Fi, and VPNs

Common sense and being aware of potential dangers are powerful lines of defense in maintaining the security of your Android-powered device. Avoid clicking on suspicious links or downloading files from untrusted sources, and you will not go far wrong. In addition, ensure there is a padlock icon in the address bar, particularly on websites where you are entering personal information, because this shows the connection between your web browser and the website server is encrypted.

Public Wi-Fi networks can be convenient, but they are often less secure, making them a target for cybercriminals. By all means, use public Wi-Fi for everyday internet browsing, but think twice about completing sensitive transactions like online banking while connected to public Wi-Fi. If you must use public Wi-Fi to conduct your business, consider installing a Virtual Private Network (VPN).

VPN use is increasing as more people take threats to their online privacy and security more seriously. VPNs are highly complex, but their apps are simple to use, even for the less tech-savvy Android users out there. At their core, VPNs encrypt your internet connection to make it impossible for anyone to eavesdrop on your online activities. It would take a would-be hacker billions of years to brute-force crack AES-256 encryption, meaning it is virtually impossible to do so.

Back-Up Your Data and Enable Remote Tracking and Wiping

Computer users are constantly reminded to back up their data in case the unthinkable happens, and their hard drive fails. There are few things in life as frustrating as losing all of the data stored on a device. Android smartphones and tablets often contain hundreds of phone numbers and email addresses, countless photographs and videos (some irreplaceable), and even work-related documents. Regularly backing up your data to a secure location, such as cloud storage or an external hard drive, means your important information is easily recoverable should your device become compromised.

Similarly, most Android phones and tablets have a “Find My Device” feature that allows you to track your device should you lose it. Enabling this feature makes it possible to send messages to your phone or tablet, lock the device, or even erase its contents from another device or computer. 


Android security is more critical than ever right now, not least because we are becoming ever more reliant on our smartphones and tablets in our day-to-day lives. Keeping your device and apps up-to-date is your first line of defense and the most crucial step you can take to secure your Android device.

Common sense and being vigilant also play a significant role because most virus infections or similar stem from user error rather than hackers gaining access to a phone or tablet. Keep your wits about you whenever you access the internet.

You have just learned about some ways to stay safe online while using an Android device, so by incorporating those tools and practices, you can keep your device safe
