Samsung Galaxy May Face OS Update Cutoff, Putting Millions at Risk
**The Samsung Galaxy S21 smartphone series is facing an uncertain future when it comes to software updates, leaving millions of users vulnerable to security threats. The 2021 flagship lineup, which includes the S21, S21+, and S21 Ultra models, was initially promised five years of security updates upon its release in January 2021.
However, with the latest firmware update, G99xNKSSCHZA5, which brings the January 2026 security patch addressing 55 known vulnerabilities, it appears that Samsung has reached the end of its software support window. Despite this, Samsung has not formally announced the end of support for these devices.
The lack of protection will leave Galaxy S21 owners exposed to malware, hacking attempts, and compromised applications. Without regular updates, phones become more susceptible to online threats, making it a broader cybersecurity issue across the Android ecosystem.
As one of Samsung's best-selling models, the Galaxy S21 series remains widely used, with banking apps, password managers, and two-factor authentication increasingly common on smartphones. The absence of software support will put users at risk, especially considering the escalating online threats.
The situation is set to worsen in February, when Samsung may remove the S21 models from its quarterly update list, officially concluding all support. Users who continue using their devices beyond that point will do so without the safety net of guaranteed software maintenance.
Meanwhile, Samsung's newer flagships, such as the Galaxy S25 and upcoming Galaxy S26, offer up to seven years of software support, providing users with a safer and more secure mobile experience. Trade-in values for the Galaxy S21 are currently modest, around $100 for a base model toward a new Galaxy S25 Ultra, but are expected to decline further once the S26 is released.
For those considering an upgrade, Samsung's foldable phones, such as the Z Fold 7 and Z Flip 7, offer full software support. Mid-range models like the Galaxy A57 are also expected to receive extended security updates.
Users who opt to keep their Galaxy S21 devices may still find basic performance intact, but will need to weigh the risks of operating without ongoing security protection. Newsweek has attempted to reach Samsung for comment via the company's website.
The unfolding situation serves as a stark reminder that smartphone manufacturers have a responsibility to ensure their devices remain secure and protected against online threats. As the digital landscape continues to evolve, users must be aware of the importance of staying up-to-date with software updates to avoid falling victim to cyber attacks.
