Samsung Galaxy S21 Series Loses Security Support, Users Urged to Upgrade
Samsung Ends Security Updates for Galaxy S21 Series

Samsung has issued a critical alert for owners of its popular Galaxy S21 smartphone series, confirming that these devices will no longer receive essential security updates. The technology giant has officially ended support for the Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra, removing them from its security update page. This development means users of these models, first launched in 2021, are now at increased risk of cyber threats and data breaches without ongoing software protection.

Security Update Page Revised

As recently spotted by TechRadar, Samsung updated its official security update tracking page to exclude the S21 series. This page monitors all Samsung phones that continue to receive monthly or quarterly security patches, which are distinct from annual Android version upgrades. The removal indicates that these older models will not get any further system updates, leaving them exposed to potential vulnerabilities.

End of Promised Support Period

When the Galaxy S21 series debuted, Samsung committed to providing four years of Android updates and five years of security updates. With 2026 marking the end of this five-year window, the company has fulfilled its obligations. In contrast, newer models like the Galaxy S25 now offer extended support with seven years of both Android and security updates, significantly enhancing device longevity and user security.

Implications for Current Users

For those still using a Galaxy S21, S21 Plus, or S21 Ultra, this change poses a serious security concern. Without regular patches, these phones become more susceptible to hacking, malware, and data theft. Experts advise considering an upgrade to maintain protection, especially for users who handle sensitive information or rely heavily on their devices for daily tasks.

Galaxy S21 FE Still Supported

It is important to note that the Galaxy S21 FE remains on the supported list, receiving quarterly security updates. This model should continue to get patches for at least another year, offering a temporary reprieve for owners. However, its eventual phase-out highlights the broader trend of planned obsolescence in the smartphone industry.

Upgrade Considerations and Timing

If this news prompts thoughts of upgrading, timing could be advantageous. Samsung is anticipated to unveil the Galaxy S26 series later this month, with rumors suggesting a launch as early as February 25. Expected enhancements include a faster processor, improved camera capabilities, a more durable design, and better battery life, making it a compelling option for those seeking modern features and extended security support.

As the situation evolves, users are encouraged to stay informed about Samsung's announcements and weigh their options carefully to ensure continued device security and performance.
