Samsung Internet’s Security Gap: Why Monthly Patches Don’t Protect Your Browser

Samsung Internet Browser Updates Are Separate From Galaxy Security Patches, and That Matters

Samsung Galaxy phones receive monthly security updates, and for many users that creates a sense of safety. A notification appears, the phone downloads a patch, restarts, and the security patch date changes in the settings menu. For most parts of the Android system, that monthly update is important and useful.

But one major app on Galaxy devices follows a different update path: Samsung Internet Browser.

Samsung’s browser comes preinstalled on Galaxy phones, but it is not updated through the same monthly firmware patch that updates the rest of the system. Instead, Samsung Internet receives updates through the Google Play Store and the Galaxy Store. That means your phone can show the latest Android security patch while the browser may still depend on an older browser engine underneath.

For an app that opens websites, runs scripts, handles logins, and interacts with online accounts every day, that distinction is important.

Why the Chromium version matters

Samsung Internet is not built completely from scratch. Like Google Chrome, Microsoft Edge, Opera, and several other browsers, it is based on Chromium, the open-source browser project.

Inside Chromium is V8, the JavaScript engine responsible for running code used by websites. Nearly every modern website relies on JavaScript for login pages, shopping carts, email services, banking portals, ads, videos, and interactive features.

When a serious flaw is found in V8, it can become a major security risk. In some cases, simply opening a malicious or compromised webpage may be enough to trigger an attack. Once Google or the Chromium project fixes such a flaw, the details eventually become public. That creates a dangerous window of time for browsers that have not yet integrated the fix.

Security experts often call this an “N-day” vulnerability. Unlike a zero-day flaw, which is unknown to the software maker, an N-day flaw is already known and patched upstream. The problem is that not every downstream browser receives the fix immediately.

That delay is known as the patch gap.

The patch gap problem on Android browsers

With Google Chrome, fixes usually arrive quickly because Google controls both the browser and the Chromium changes behind it. But when another company builds its own browser on Chromium, it has to pull in the fixes, test them, package the update, and distribute it separately.

That process can take time.

For Samsung Internet on Android, the situation is harder to judge because Samsung has not publicly listed the exact Chromium base used by the Android version of the browser for more than two years. The company does maintain visible version information for the Windows version, but Android users are left without the same level of detail.

That means Galaxy owners can see the Samsung Internet app version, but they cannot easily verify which Chromium version or V8 engine is running under the hood.

What researchers found on a Galaxy S25

Security researchers from OtterSec, working with the group Crusaders of Rust, demonstrated why this lack of visibility matters.

On April 1, 2026, they analyzed Samsung Internet on a Galaxy S25. To find the underlying browser engine version, they had to extract the app from the phone and inspect its files manually, something an average user would not normally do.

They reportedly found that the browser was using V8 13.6, which was already around six months old at the time.

Using a vulnerability that had already been fixed in Google Chrome, the researchers built a working attack against the older engine. Their demonstration showed that malicious code could run inside the browser and execute in the context of websites.

In a real-world scenario, that type of weakness could potentially allow a specially crafted webpage to access information from other open pages in the same browser process, such as an email inbox, a shopping account, or another signed-in website.

The issue was made more serious by the way Android browsers handle process isolation. On desktop computers, modern browsers often place each website into its own process, reducing the chance that one malicious page can interfere with another. On Android, process separation can be more limited. Some logged-in or specially marked pages may receive stronger isolation, but many ordinary pages can share the same process.

That creates more opportunity for a browser engine vulnerability to cause damage.

The specific vulnerability used in the research has since been fixed. The larger concern remains: users still do not have a simple public way to confirm how quickly Samsung Internet receives every important Chromium and V8 security fix.

Monthly Galaxy updates do not cover everything

Samsung’s monthly security patches are still important. They fix vulnerabilities in Android, the system framework, device drivers, Samsung software components, and other low-level parts of the phone.

However, they do not automatically update every app that connects to the internet.

Samsung Internet is updated like a regular app. It depends on updates delivered through the Play Store or Galaxy Store. If automatic app updates are disabled, delayed, restricted to Wi-Fi, or blocked by regional rollout timing, the browser may not be running the newest available version.

This is why a Galaxy phone can be fully updated at the system level while still needing a browser update.

The challenge is that even after updating Samsung Internet, users still cannot clearly see which Chromium base is included. Public browser identifiers found online can be inconsistent, unreliable, or even fake. App version numbers alone do not reveal enough.

Samsung’s public notes may mention that security issues were fixed, but they do not always identify which Chromium vulnerabilities were addressed or when they were included.

That becomes especially important when Google fixes a high-severity V8 flaw and reports that an exploit is already being used in the wild. Without clear documentation, users and security teams cannot easily confirm whether Samsung Internet has received the same protection.

How to check your Samsung Internet version

Galaxy users can check whether Samsung Internet is updated in just a few steps.

Press and hold the Samsung Internet icon on the home screen or app drawer.

Tap the small app info icon, usually shown as an “i”.

Look for the installed app version.

Open the Google Play Store or Galaxy Store and search for Samsung Internet.

If an update button appears, install it.

You can also open Samsung Internet, go into its settings menu, and check the app information section to see the installed version.

This will tell you which Samsung Internet app version is installed. It will not necessarily tell you the exact Chromium or V8 version underneath, which is the key transparency issue.

What Galaxy users can do to stay safer

The simplest step is to keep automatic app updates enabled in both the Play Store and Galaxy Store. That way, when Samsung releases a new Samsung Internet build, your phone can install it without waiting for manual action.

Users who want more transparency can also install another browser as a backup or default option. Chrome and Firefox are updated directly by their developers and clearly show their own version numbers in the app menu. They also receive browser engine updates independently from Samsung’s monthly phone firmware schedule.

To change the default browser on Android, open Settings, go to Apps, then Default apps, and select your preferred browser.

That does not mean Samsung Internet is a bad browser. Many Galaxy users like it because it is fast, integrates well with Samsung Pass, supports useful privacy features, and includes strong ad-blocking options through extensions. For people inside the Samsung ecosystem, it can be convenient and polished.

The main issue is not usability. It is visibility.

For a browser installed on hundreds of millions of devices, users should be able to know which Chromium base is active and whether critical web security fixes have arrived.

The bottom line

Samsung’s monthly Galaxy security patch protects many important parts of your phone, but it does not automatically guarantee that Samsung Internet is fully current. The browser is updated separately through app stores, and the exact Chromium version used in the Android app is not clearly published for users.

If you use Samsung Internet, keep automatic updates enabled and check both the Play Store and Galaxy Store regularly. If you want clearer browser engine information, consider using an additional browser that publishes its version details more directly.

Your phone’s security patch date matters, but it is only one part of the security picture. On any modern smartphone, the browser is one of the most exposed apps you use every day, and keeping it updated is just as important as installing the monthly system patch.
