Your smartphone is more than just a communication tool – it’s your wallet, your photo album, your ID, and your gateway to the internet. With so much personal data stored on mobile devices, hackers are constantly looking for ways to exploit vulnerabilities. Fortunately, there are simple steps you can take to protect your device and your data.

This guide from Google Keith, your trusted source for tech questions and how-to guides, will walk you through the essential practices to help secure your smartphone from hackers.

Keep Your Operating System and Apps Updated

One of the easiest and most effective ways to protect your mobile device is to keep your operating system (OS) and apps up to date. Software updates often include patches for security vulnerabilities that hackers can exploit.

Why It Matters

  • Hackers target known flaws in outdated software.
  • Updates improve both security and performance.

What You Can Do

  • Enable automatic updates for your OS and apps.
  • Regularly check for updates manually if auto-update is off.
  • Delete apps you no longer use to reduce potential entry points.

Use Strong Passwords and Biometric Locks

Your lock screen is the first line of defense. A weak password or no password at all makes it easy for someone to access your device if it’s lost or stolen.

Best Practices

  • Use a strong passcode (avoid “1234” or your birthdate).
  • Enable biometric authentication like fingerprint or facial recognition.
  • Avoid using the same password across multiple accounts.

Pro Tip

Use a password manager to generate and store complex passwords securely.

Enable Two-Factor Authentication (2FA)

Two-factor authentication adds an extra layer of security by requiring a second form of verification in addition to your password.

How It Works

After entering your password, you’ll be asked to verify your identity via a code sent to your phone or an authenticator app.

Where to Use It

  • Email accounts
  • Social media
  • Banking apps
  • Cloud storage

Recommended Tools

  • Google Authenticator
  • Microsoft Authenticator
  • Authy

Be Cautious with Public Wi-Fi

Public Wi-Fi networks are convenient but often insecure. Hackers can intercept data transmitted over these networks, including passwords and personal information.

Tips for Safe Browsing

  • Avoid accessing sensitive accounts on public Wi-Fi.
  • Use a Virtual Private Network (VPN) to encrypt your connection.
  • Turn off auto-connect to open networks in your settings.

Install Apps Only from Trusted Sources

Downloading apps from unofficial sources can expose your device to malware and spyware.

Safe Practices

  • Stick to the Google Play Store or Apple App Store.
  • Check app reviews and developer information.
  • Be wary of apps that ask for excessive permissions.

Watch Out For

Apps that request access to your contacts, camera, or microphone without a clear reason.

Review App Permissions Regularly

Even legitimate apps can overreach when it comes to permissions. It’s important to audit these settings regularly.

How to Do It

  • On Android: Go to Settings > Privacy > Permission Manager.
  • On iOS: Go to Settings > Privacy & Security.

Permissions to Monitor

  • Location
  • Microphone
  • Camera
  • Contacts

Revoke access for apps that don’t need it to function properly.

Use Mobile Security Software

Just like your computer, your smartphone can benefit from antivirus and anti-malware protection.

What to Look For

  • Real-time scanning
  • Anti-theft features (remote lock, wipe)
  • App privacy analysis

Trusted Apps

  • Norton Mobile Security
  • Bitdefender Mobile Security
  • Avast Mobile Security

Back Up Your Data

If your phone is ever hacked, lost, or damaged, having a backup ensures you don’t lose important data.

Backup Options

  • Cloud Backup: Microsoft OneDrive (all platforms), Google Drive (Android), iCloud (iOS)
  • Local Backup: Backup to your computer via USB or Wi-Fi

What to Back Up

  • Photos and videos
  • Contacts
  • Messages
  • App data

Set up automatic backups to keep your data safe without thinking about it.

Be Aware of Phishing and Social Engineering

Hackers often use deception to trick users into giving up personal information.

Common Tactics

  • Fake emails or texts pretending to be from your bank or a trusted service.
  • Links that lead to fake login pages.
  • Urgent messages asking for immediate action.

How to Stay Safe

  • Don’t click on suspicious links.
  • Verify the sender before responding.
  • Use spam filters and report phishing attempts.

Lock Down Bluetooth and Location Settings

Leaving Bluetooth and GPS on all the time can expose your device to tracking and unauthorized access.

Best Practices

  • Turn off Bluetooth when not in use.
  • Use While Using the App for location access.
  • Disable location history if you don’t need it.
