The Ultimate Guide to Android Security Updates: Why They're Vital for Your Device

Android updates are a common subject that often arises in discussions about the Android operating system. It's worth noting that there are various kinds of Android updates, including one known as a "Security Update." So, what sets these updates apart, and why are they of such great significance?

This article on Cybersecurity Awareness Week is presented with the support of Incogni.

What Is an Android Security Update?

In the realm of Android, updates can be broadly classified into three categories: major yearly firmware updates that increment the version number (for instance, Android 13 to Android 14), smaller monthly security updates, and "Google Play System Updates," which are a distinct type of security update.

An Android Security Update aims to enhance security and resolve bugs, rather than introduce noticeable features for daily use. Although Android typically receives one major version update annually, this frequency is insufficient to keep it fully protected against security threats and bugs.

With the release of a new Android version, it is expected that some issues may arise, as is common with any human-designed product. However, Google prefers not to send a complete system update solely for the purpose of addressing these bugs. Instead, they opt for smaller updates to rectify the specific problems.

These updates, as the name suggests, are crucial for security purposes. Certain bugs pose security risks, but these can be swiftly resolved through updates. Additionally, security updates effectively address vulnerabilities to emerging attacks. They are commonly referred to as "patches," resembling small fixes that enhance the overall functionality of the operating system.

Why Are Android Security Updates Important?

Installing an Android Security Update might not bring any flashy new features to your attention, but their significance should not be overlooked. Software is an ongoing endeavor that requires regular maintenance and updates in order to ensure its safety and security.

These smaller updates play a crucial role in addressing bugs and patching vulnerabilities. Imagine them as tiny holes in a bucket filled with water. While a few small holes may not significantly affect the water level, a multitude of holes could result in the complete bottom falling out.

As mentioned earlier, smaller updates are also essential in promptly addressing new security vulnerabilities. Waiting for a complete version update to fix a glaring security risk is undesirable. Smaller updates enable a faster turnaround time, so it is important to download them as soon as possible.

How to Check for Android Security Updates

With all that in mind, you're probably wondering how to check whether you have the latest security update. It's easy to find out.

First, swipe down from the top of the screen (once or twice, depending on your device's manufacturer). Then, tap the gear icon to open the Settings menu.

Tap "Security & Privacy."

Scroll down to "System & Updates."

Now, you can see the date for the security update on your device.

There is a high likelihood that you may not have the latest update for the current month due to the frequent lag experienced by many Android devices. However, if you own a relatively new Samsung phone or a Google Pixel, it is expected that your device will have the most recent updates.

To verify if an update is available, simply navigate to the "Security Update" section and tap the "Check for Update" button.

Why Is My Android Phone behind on Security Updates?

Ideally, every Android device should receive the latest security update simultaneously, but unfortunately, that is not the reality.

Google releases security updates for its partners (such as Samsung, OnePlus, etc.) on a monthly basis, providing them with the necessary fixes. However, it is the responsibility of these companies to review and approve the fixes, incorporate any additional changes, and subsequently deliver the updates to their respective devices.

Pixel phones usually receive security updates promptly because Google has complete control over the entire process. On the other hand, other devices rely on the manufacturer for updates. While Samsung is proficient at keeping its high-end devices up to date, some lower-end phones may experience delays.

Prior to purchasing an Android phone, it is advisable to invest some time in researching the manufacturer's commitment to providing updates. For instance, Samsung assures five years of updates for numerous devices. It is recommended to avoid manufacturers with a history of delivering poor updates.
