Samsung has officially reached the end of software support for the Galaxy S21, S21+, and S21 Ultra. While modern Samsung flagships now boast seven years of updates, this older generation was subject to a different policy. Launched in January 2021, these devices were promised four major Android OS updates and five years of security patches.

As of today, those five years have passed. This means owners of these devices will no longer receive vital security updates or system improvements, potentially leaving the hardware vulnerable to new exploits over time. For those still using these phones, it may be the ideal moment to transition to a newer model to ensure data protection and access to the latest features.

Recommended Upgrades for S21 Users

With the support cycle for the S21 series concluded, the Galaxy S25, S25+, and S25 Ultra serve as logical successors. These newer models offer significantly improved performance, better cameras, and longer-term support. Current buyers may also find hefty discounts on these models as Samsung prepares for the launch of its next generation of smartphones.
