Samsung's 2023 phones hit their promised OS limit with the latest update.
TL;DR
- Engadget reports One UI 9 is the final major OS upgrade for 2023 Galaxy S23 series, Z Fold 5, Z Flip 5 and select A-series models.
- According to Engadget, the update started rolling out in South Korea on October 14, 2026, with security patches continuing through 2028.
- According to Engadget, newer S24 and later devices get seven years of updates, but the policy does not apply retroactively to 2023 models.
Engadget reports that Samsung’s One UI 9, based on Android 17, is the last major software upgrade for several 2023 Galaxy models. This includes the S23 series, Z Fold 5, Z Flip 5, and certain A-series phones from that year.
According to Engadget, the rollout started in South Korea on October 14, 2026 for the S23 lineup, reaching Europe shortly after. The foldables received it in the US on October 23. Engadget notes a Samsung support rep confirmed this as the final OS jump, according to a tip shared via SamMobile.
According to Engadget, these devices still receive security patches through 2028, matching Samsung’s original five-year promise from launch. Engadget points out the S23 series launched on Android 13, so the four promised upgrades are now complete with Android 17.
According to Engadget, other 2023 models like the S23 FE, A54, A34, M54 and the Tab S9 series are in the same situation. Newer phones starting with the S24 get seven years of updates instead, but that policy did not apply retroactively.
The Tea
This draws a clear line under Samsung’s older flagships, pushing owners to weigh upgrades sooner even if the phones keep running fine. Security support lingers, but the feature train stops here.
