Millions of Android Users Face a Growing Security Threat
Google has issued a major security warning that should concern Android users worldwide. According to the company’s latest Android distribution data, more than 40% of all Android phones are now at serious security risk because they no longer receive critical software updates. This means over one billion devices could be vulnerable to malware, spyware, and other cyberattacks.
The issue stems from outdated operating systems that no longer qualify for Google’s core security patch support. As cybercriminals continue to target mobile devices, experts say users with unsupported phones should act quickly to protect their data.
Why Older Android Versions Are No Longer Safe
Google’s newly released Android version breakdown shows slow adoption of the latest software:
Current Android Version Distribution
-
Android 16: 7.5%
-
Android 15: 19.3%
-
Android 14: 17.9%
-
Android 13: 13.9%
These versions still receive security updates. However, Android 12 and all earlier versions are officially unsupported, meaning they no longer get critical fixes for newly discovered vulnerabilities.
With less than 60% of Android phones still under active protection, a massive portion of users are exposed to threats with no way to patch their devices.
Malware and Spyware Attacks Are Increasing
The timing of this update is especially concerning. Google previously warned that new spyware campaigns targeting Android users are already active. Phones running outdated software are defenseless against these attacks, even if users are cautious.
Unlike temporary update delays, unsupported devices are permanently exposed. Security researchers warn that attackers actively seek out these older systems because vulnerabilities remain unpatched.

Samsung Users Hit by Surprise Support Cut
Galaxy S21 Series No Longer Receives Security Updates
Adding to the concern, Samsung has confirmed that its Galaxy S21, S21+, and S21 Ultra have reached the end of their update lifecycle. Despite being relatively recent flagship models, these phones will no longer receive Android or security updates.
Technology experts warn that continuing to use these devices may pose significant privacy and data protection risks, especially as new exploits emerge.
Samsung has also reduced update frequency for:
-
Galaxy S22 series
-
Galaxy S21 FE
These models have been downgraded from monthly to quarterly security updates, leaving users exposed for longer periods between fixes.
Google’s Advice for Users With Older Phones
Google emphasizes that some protections remain in place:
What Still Works
-
Google Play Protect continues to support devices as old as Android 7
-
Real-time malware scanning and updated threat signatures are still available
However, experts agree that Play Protect alone is not enough to defend against advanced exploits targeting system-level weaknesses.
Should You Upgrade Your Phone?
Security professionals strongly recommend upgrading if your device cannot run Android 13 or newer.
Why a Newer Phone Is Safer
-
Regular security patches
-
Protection against zero-day exploits
-
Better app compatibility
-
Improved privacy controls
A mid-range phone with active support is considered far safer than an older flagship that no longer receives updates.
What Android Users Should Do Right Now
Immediate Safety Steps

Final Thoughts
The Android security risk highlighted by Google is not a future concern—it’s already happening. With cyber threats growing more sophisticated, outdated phones are becoming easy targets. While Google continues to offer limited protection through Play Protect, long-term security depends on running a supported Android version.
For millions of users, upgrading may no longer be optional—it’s essential.
