Android is entering a dangerous phase. More than one billion users worldwide are now using phones that no longer receive critical security updates, and the risk is growing fast. According to the latest platform data, a large portion of the Android ecosystem is effectively stranded on outdated software.
For many Samsung users, this is no longer a distant concern. It has become a real and immediate problem.
Android update gap leaves massive exposure
Recent Android distribution figures show just how wide the gap has become. Android 16 runs on only a small fraction of active devices, while newer versions like Android 15 and 14 remain far from universal. Everything below Android 13 is now falling behind in terms of core security protection.
More than 40 percent of Android phones globally are still operating on Android 12 or older. That translates to over one billion devices that no longer receive essential system-level security patches.
Galaxy S21 reaches end of support
As of February 2026, the Galaxy S21 lineup has officially reached the end of its update lifecycle. While the Galaxy S21 FE remains supported for a short time longer, the main S21 models are no longer receiving full security updates.
This means a former flagship device, released just a few years ago, is now more vulnerable than many newer mid-range phones that continue to receive regular updates.
Active spyware campaigns raise alarm
Google has warned that Android is once again facing active spyware threats. These attacks are not hypothetical. They are already circulating and targeting weaknesses that exist only in older Android versions.
Devices stuck on unsupported software are unable to defend against these newer exploits, even if users believe their phones are still protected.
Why Google Play Protect is not enough
Google has emphasized that Play Protect continues to support devices running Android 7 and above. Apps still receive updates, malware definitions are refreshed, and basic scanning remains active.
However, Play Protect cannot fix deep system vulnerabilities. It does not patch the Android kernel or repair security flaws at the operating system level. Once official updates stop, the foundation of the device remains exposed.
In simple terms, malware detection alone cannot replace full security updates.
Samsung users face tough choices
For Samsung fans, the situation highlights a growing divide between hardware longevity and software support. A premium phone that cost hundreds of dollars can become a security liability in just four or five years.
This has pushed many users to reconsider upgrade timing. Holding onto an older flagship may feel economical, but it now comes with hidden risks that are easy to overlook.
Apple faces similar pressure, but with a key difference
Apple is dealing with slower adoption of its latest iOS version, but the situation is not the same. iPhones that are eligible for updates eventually receive them, closing the security gap over time.
On Android, many devices never move forward once support ends. There is no delayed fix waiting in the background.
What users can do now
If your Android phone no longer receives security updates, the safest options are limited. Upgrading to a newer device with guaranteed long-term support is the most reliable solution.
At a minimum, users should avoid sideloading apps, keep Play Protect enabled, and limit sensitive activity on unsupported devices. Still, these are temporary precautions, not permanent fixes.
The Android ecosystem’s size is both its strength and its weakness. While choice and variety remain unmatched, fragmented update support continues to leave hundreds of millions of users exposed.
As Android threats grow more sophisticated, long-term software support is no longer a luxury. It is a necessity.
