Important Android Security Tips

Samsung Galaxy Note 20 Ultra Review AM AH 20 1

The world is condensing into a tiny interconnected network of pocket-sized computers, and all kinds of data, from emails and messages to social media apps and family images, can be found on these devices. While this may make our lives easier, it also gives cybercriminals an extra avenue into our private information. Read on for five Android security tips to keep your devices and data safe.

1. Use a password

There are many ways to unlock your Android phone: swiping, using a password, entering a PIN, drawing a pattern, using a fingerprint scanner or implementing face ID. Each of these has a different security level; swiping is the most insecure option, followed by PIN, pattern, password, and Face ID/fingerprint in that order. For phones that don’t have fingerprint scanners or the Face ID option, passwords make for the most secure alternative. If a pattern is going to be used, ensure it doesn’t leave a trail when drawn.

2. Secure your connections

Since you carry your phone everywhere, there is a good chance you will connect to a restaurant or bank Wi-Fi network at some point. These networks are often not secured, and your data may be accessed by third parties. The best way to avoid this is to install a virtual private network (VPN) on your Android device and encrypt your home Wi-Fi for maximum protection.

3. Use two-factor authentication (2FA)

Implementing two-factor authentication is the best way to prevent unauthorized individuals from accessing your account from other devices. 2FA serves as a backup for your password, meaning even if someone got hold of your login credentials, they would still need your device to complete a login.

It may be time-consuming and irritating, but it can significantly enhance your security level and give you peace of mind.

4. Regularly update your OS and apps.

Malware typically targets old app versions, which are often riddled with vulnerabilities. The latest versions come with patches for known weaknesses in earlier releases. These new versions are harder to breach since hackers first need to identify vulnerabilities. By the time they identify them, it’s likely the application developer will have perceived them, too. Essentially, newer apps and operating systems will keep you ahead of individuals with malicious intent.


5. Install apps from the Play Store only

The “Unknown Sources” option in your phone’s developer options settings allows for the installation of applications from sources other than Google Play Store. If you enable it, you are able to install APKs downloaded from random websites on the internet. There are many useful applications that are not on Play Store, but it’s advisable to avoid getting your apps from unknown sources as there is a good chance you may install malware in your phone.


Your Android phone may not be as vulnerable to cyber-attacks as your PC, but the threat is still significant. Follow the above tips to increase your security and keep your data away from the prying eyes of hackers.
