Hidden Security Updates May Be Waiting on Your Phone

Even when your phone indicates it is up-to-date, additional security fixes or protections might be available through separate update channels. Apple, Google, and Samsung each employ distinct methods for delivering these crucial security patches between major software releases.

iPhone Security Enhancements

Apple's iPhones running iOS 27 can receive security improvements through a feature called Background Security Improvements. These updates are designed to protect components like Safari and WebKit without requiring a full operating system update. To ensure this feature is active on your iPhone:

• Open Settings.
• Tap General.
• Tap Software Update.
• Install any available updates to ensure you are running the latest version of iOS 27.

Once your iPhone is updated, navigate to Settings > Privacy & Security and enable "Automatically Install" under Background Security Improvements. While these background updates offer immediate protection, it is still essential to install full iOS updates, which contain broader security patches and system enhancements.

Samsung Galaxy Updates

Samsung Galaxy phones, which run Android with Samsung's One UI software, have a multi-layered update process. Owners of devices running One UI 9, for instance, should check for both Samsung's system updates and Google Play system updates.

To check for the latest Samsung software:

• Open Settings.
• Scroll down and tap Software update.
• Tap Check for updates and install if prompted.

To verify the current software version:

• Open Settings.
• Tap About phone.
• Tap Software information.

Additionally, check for Google Play system updates:

• Open Settings.
• Tap About phone.
• Tap Software information.
• Tap Google Play system update and follow any prompts.

Google Pixel Security Checks

Google Pixel phones running Android 17 also have distinct update pathways. While Pixel devices receive regular Android software updates that include security fixes, Google Play system updates are handled separately.

To check for the latest Android update:

• Open Settings.
• Tap System.
• Tap Software update.

To check for Google Play system updates:

• Open Settings.
• Tap About phone.
• Tap Android version.
• Look for Android security update and Google Play system update sections.

Install any available updates to ensure your device is protected.

The Importance of Verifying Updates

While automatic updates can be convenient, it is advisable to periodically check these specific update screens. Some updates require a phone restart to become fully active, and automatic processes might be delayed by factors like battery life or Wi-Fi availability. Ensuring all available security patches are installed is crucial, especially as manufacturers eventually cease support for older devices. Google currently provides seven years of updates for Pixel 8 and newer models, while Samsung also offers extended support depending on the device. iPhones also receive years of software and security updates, but older models will eventually stop receiving the newest iOS versions.

Beyond software updates, maintaining phone security involves employing strong passcodes, biometric security, and utilizing features like password managers and reputable antivirus software to protect against phishing, malicious apps, and other online threats.
