Support for the Galaxy S21 is coming to an end, which impacts the security updates you will receive.

      Samsung has altered the update status for the Galaxy S21 regarding security updates. The latest security update pages no longer list the Galaxy S21, S21 Plus, or S21 Ultra as part of the monthly or quarterly tracks, indicating that these devices are likely out of the regular patch cycle.

      Changes in updates typically occur gradually. However, it would be wise not to rely on a consistent schedule for new patches, especially if you utilize banking applications, store two-factor authentication codes, or access work accounts on your phone.

      This change aligns with the S21's initial timeline. The series launched in 2021 and has already received the expected four major Android OS upgrades, including Android 15 with One UI 7 anticipated in the first half of 2025. The last routine security patch was reportedly provided late last year.

      The S21 has now diverged from the standard update track.

      A significant aspect of this shift is the alteration in expectations. Phones listed for monthly updates receive consistent security maintenance, while devices not on any list enter a waiting phase for updates, which may only occur when significant issues arise.

      Although your S21 may feel the same on a daily basis, moving away from the update schedule often means longer intervals between the minor updates designed to mitigate security risks over time.

      Implications for daily use

      For most users, the main downside is increased uncertainty. If you conduct financial transactions, store sensitive documents, or depend on your phone for work login, extended time between updates raises the stakes for maintaining robust account security, strong passwords, timely app updates, and careful app permissions.

      It also clarifies a common misconception. Samsung's new seven-year update policy applies only to the Galaxy S24 series and does not extend the support period for the S21.

      Next steps if you continue using it

      If you decide to keep your S21, ensure it's updated with the latest available version, and focus on implementing basic security measures to minimize the risk of account compromises. Utilize a strong screen lock, keep applications up-to-date, and delete any unused apps. Take action promptly.

      If you're considering an upgrade, there's no need to rush into purchasing a new flagship device. Consider your usage patterns, and explore the current best Samsung phones. If you frequently handle accounts and work access, a newer model with a consistent update schedule would be more advisable. For lighter usage, you can afford to wait as long as you maintain discipline and periodically check Samsung’s update pages.
