Most of us are used to ignoring security update notifications. Even I often treat them this way. Like, what is it this time — another stability improvement? Although sometimes updates are truly important. The March patch for Android is exactly the case when you shouldn’t ignore it. Samsung has already released an update closing 65 vulnerabilities, 8 of which are recognized as critical. Let’s break down why they’re dangerous and how to check whether the protection has reached your smartphone.
The Android update is more important than many think.
What Vulnerabilities Were Found in Android
Let me start with the main point: critical vulnerabilities in Android are not an abstract threat, but a very real opportunity for attackers to gain access to your smartphone without any visible action on your part. The most dangerous class of such holes is Remote Code Execution, meaning the execution of arbitrary code remotely. If such a vulnerability exists in a component that processes incoming data (for example, in a media codec or the Bluetooth stack), it’s enough to simply be within the attacker’s range.
The March 2026 Android security bulletin features vulnerabilities in several system components at once. Some of them affect the Linux kernel, others affect proprietary drivers and Qualcomm components. This is exactly why each manufacturer has its own patch: Google releases a base update, and Samsung, Xiaomi, and others add their own fixes for specific chips.
Which Samsung Smartphones Have Already Received the Patch
Samsung didn’t delay with the March update. The patch is already available for the flagship Galaxy S26, S25, S24, and S23 lineups. If you have one of these smartphones — check for updates right now. Settings → Software Update → Download and Install.
Always check if there’s an update available for your phone.
Owners of budget and mid-range devices will have to wait longer. Samsung traditionally rolls out patches to flagships first, then to the A series, and only then to the most affordable models. If you have a Galaxy A35, A25, or something from the M lineup — the update will most likely arrive within a few weeks, not days.
It’s also worth noting that the March update closes not only Android vulnerabilities but also specific holes in the proprietary One UI shell. So Samsung’s list of fixed issues is even broader than that of “stock” Android.
What to Do While Waiting for the Update
While the patch is on its way to your smartphone, there are a few simple measures that will reduce risks. First, don’t connect to unfamiliar public Wi-Fi networks — some vulnerabilities are exploited specifically through the network. Second, don’t open suspicious links in messengers — even from familiar contacts, if they may have been compromised.
And the most obvious but effective advice: enable auto-updates for apps and the system itself. Many people keep this feature turned off to save data — and end up walking around with security holes for months. Critical patches usually don’t weigh much, but they close exactly those vulnerabilities that attackers are actively exploiting. This is definitely not the place to save on data.
