Samsung Galaxy smartphone owners are urged to check their device models as Samsung has officially discontinued support for three older models – Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra. These models will no longer receive essential software updates, according to Samsung’s recent security update page.
Manufacturers typically provide security patches even after main Android version updates cease to protect against vulnerabilities and data breaches. However, the exclusion of the S21 series from the supported devices list suggests that they will not receive further system updates. Users still using these phones, released in 2021, may want to consider upgrading for enhanced security.
Initially, Samsung had promised four years of Android updates and five years of security updates for the S21 series, which have now reached their end in 2026. The newer Galaxy S models, like the Galaxy S25, now guarantee seven years of both Android and security updates, prolonging the device’s usability.
Notably, the Galaxy S21 FE continues to receive quarterly security updates and is expected to do so for at least another year. For those contemplating an upgrade, it may be prudent to wait as the Galaxy S26 series is anticipated to be announced later this month, possibly as early as February 25. The upcoming series is rumored to feature enhancements such as a faster processor, improved camera, enhanced design, and better battery life.
Mirror Online will continue to monitor the latest updates on Samsung devices and provide timely information on any launch announcements.
