Prices move; these were read on 2026-10-05. 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.

Feature updates until
Not published by the maker
Security updates until

Basis: manufacturer commitment

Samsung's UK spec API for SM-S938BZBDEUB lists "Security Update Period (Valid until)" as 31 January 2032. That is Samsung's own date, and it is the one shown; endoflife.date records 2032-02-03. Samsung states feature (OS) upgrades as a number of Android generations rather than a date, so no feature-update end date is shown (endoflife.date estimates 2032-02-03).
