Samsung has officially ended support for three older Galaxy phone models, meaning they will no longer receive essential software updates. The Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra have been removed from Samsung’s list of supported devices for security updates, as noted by TechRadar. While manufacturers typically continue to provide security patches even after main Android updates cease, the S21 models are no longer listed. This indicates that they will not receive any further system updates, prompting users to consider upgrading for enhanced security.

Samsung had initially promised four years of Android updates and five years of security updates for the S21 series, but these commitments have now concluded in 2026. In contrast, newer Galaxy S models, like the latest Galaxy S25, offer extended support with seven years of 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 might be prudent to wait, as Samsung is anticipated to unveil the Galaxy S26 series later this month. Speculations suggest a potential launch on February 25, featuring upgrades such as a faster processor, improved camera capabilities, enhanced design, and better battery life.
