Prices move; these were read on 2026-10-04. Used and trade-in figures are CeX's own, for an unlocked handset at this device's base storage. CeX prices each colour separately, so a grade shows as the range across them. The eBay figure is the middle of the used listings on sale that day — what sellers are asking, not what anyone paid. We hold no stock and take no commission.

Basis: Maker commitment, via endoflife.date

endoflife.date records active (OS upgrade) support ending 2027-02-17 and security support ending 2028-02-17 for Galaxy S23. Samsung's UK launch article stated 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 will actually stop.
