Samsung Galaxy S21 Software Support Ends: What You Need to Know (2026)

Samsung's Software Support for Galaxy S21 Series Comes to an End

Samsung has announced the end of software support for the Galaxy S21 series, marking a significant shift for users of this popular smartphone line. The S21 series, released in 2021, was initially promised four years of major Android upgrades and five years of security updates. However, as the device approaches the end of its supported life, Samsung has decided to discontinue quarterly updates, leaving users with limited access to essential software enhancements.

The Galaxy S21 lineup, once a contender for monthly and quarterly updates, is now excluded from this support. This means that users will no longer receive the bare minimum of security updates, a critical aspect of maintaining a secure and reliable device. Samsung's official support page confirms this change, highlighting the transition to a seven-year support plan for future models like the Galaxy S25 and potentially the Galaxy S26.

The decision to remove support for the S21 series was not unexpected. Last year, Samsung shifted the device from the monthly update list to the quarterly group, indicating the end of Android upgrades. This change was followed by the discontinuation of security updates, a process that was well-known to users. For those currently using the Galaxy S21, upgrading to a newer model with consistent security updates is recommended to avoid the challenges of using an unsupported phone.
