Samsung Ends Software Support for Galaxy S21 Series: What Users Need to Know
Samsung has officially concluded software support for its Galaxy S21 series, marking the end of an era for these flagship devices. Launched in 2021, the Galaxy S21 lineup—including the S21, S21+, and S21 Ultra—was initially equipped with Android 11 and received consistent updates to stay current with Google’s latest software releases.
Samsung’s Update Commitment
At the time of release, Samsung committed to providing four years of major Android upgrades and five years of security updates for the Galaxy S21 series. This policy ensured that users would receive significant software enhancements and security patches up until early 2026. However, as of February 2026, this support period has concluded, and the Galaxy S21 series has been removed from Samsung’s official support page for monthly and quarterly updates.

Transition to Quarterly Updates
In February 2025, Samsung shifted the Galaxy S21 series from a monthly to a quarterly update schedule. This change signaled the approaching end of the devices’ support lifecycle. The transition from monthly to quarterly updates is a standard practice for Samsung, reflecting the company’s policy of reducing update frequency as devices age.

Implications for Galaxy S21 Users
With the cessation of software support, Galaxy S21 users will no longer receive security patches or system updates. This lack of updates can expose devices to potential security vulnerabilities and may result in compatibility issues with newer applications and services. Therefore, users are advised to consider upgrading to newer models that continue to receive regular updates to ensure optimal performance and security.
Samsung’s Evolving Update Policy
The Galaxy S21 series was among the last to benefit from Samsung’s previous update policy, which offered four years of major OS updates and five years of security patches. In contrast, newer models like the Galaxy S25 are now supported under an enhanced policy that provides seven years of both Android OS and security updates. This extended support reflects Samsung’s commitment to offering prolonged software maintenance for its latest devices.

Looking Ahead
As technology continues to advance, the end of support for older devices like the Galaxy S21 series is inevitable. Samsung’s updated policy for newer models ensures that users can enjoy extended periods of software support, enhancing device longevity and user satisfaction. For Galaxy S21 owners, transitioning to a newer device will provide access to the latest features, improved security, and ongoing support.
