endoflife.date records OS EOL as 2026-02-21 and security support as 2025-10-06 for Galaxy S21 5G. Both windows had already closed by the 2026-08-20 access date. Samsung later listed the S21 series among devices eligible for four generations of OS upgrades and five years of security updates. These dates are Samsung's published window as recorded by endoflife.date, not a prediction of when updates actually stopped.
