Samsung has officially ended support for three older models of its Galaxy smartphones, meaning they will no longer receive crucial software updates. The Galaxy S21, Galaxy S21 Plus, and Galaxy S21 Ultra have been removed from the list of supported devices for monthly or quarterly security patches. While manufacturers typically provide security updates even after main Android version updates cease, the S21 series is no longer listed, indicating no further system updates will be available for these 2021-released phones. If security is a concern, users of these models may want to consider upgrading.

Initially, Samsung had promised four years of Android updates and five years of security updates for the S21 series, which have now expired in 2026. In contrast, newer models like the Galaxy S25 offer up to seven years of Android and security updates, enhancing the device’s longevity.

It is worth mentioning that the Galaxy S21 FE is still getting quarterly security updates and is expected to receive them for at least another year. For those contemplating an upgrade, it might be wise to wait a bit longer as Samsung is anticipated to unveil the Galaxy S26 series later this month, possibly around February 25. Speculations suggest the new series will boast enhancements such as a faster processor, improved camera capabilities, sturdier design, and better battery performance.
