Android 17 has arrived for your 2024 Samsung flagship. One UI 9 is now rolling out in the United States to the Galaxy S25-era platform’s predecessor , the Galaxy S24, S24+, S24 Ultra, Galaxy Z Fold6, and Galaxy Z Flip6 , bringing Samsung’s latest software platform to some of its most capable hardware.
Coverage depends on how you bought your phone. Galaxy S24 series owners on AT&T and T-Mobile are receiving the update, while US customers holding unlocked versions of the Z Fold6 or Z Flip6 are also in line now.
What the Update Delivers
Samsung’s latest update ships Android 17 alongside the September 5, 2026 security patch, putting your phone’s defenses current with the most recent fixes available.
Firmware version strings confirm the build for each device. Galaxy S24 series units carry versions ending in EZIF, the unlocked Z Fold6 receives firmware F956U1UEU4EZIH, and the unlocked Z Flip6 gets F741U1UEU4EZIH.
Who Gets It and How to Find It
Samsung distributes major updates progressively across carriers and regions, so an eligible device may not receive a notification right away, even if your model is confirmed on the list.
To check manually, open Settings, select Software update, then tap Download and install. If the update has reached your specific unit, it will be available to download from that screen.
Download size matters here. Galaxy S24 owners upgrading from the previous stable release should expect a package of nearly 4GB; those moving from One UI 8.5 are looking at approximately 3.8GB. Beta participants will likely receive a smaller incremental package.
Use a reliable Wi-Fi connection before starting. A download that size on a mobile network can strain both speed and your data allowance.
Back up your data before installing. A major operating-system update is not the moment to discover your photos were not syncing properly.
What This Means Going Forward
Android 17 reaching the Galaxy S24 series and sixth-generation foldables gives owners Samsung’s current software platform without requiring a hardware upgrade.
That is a practical benefit for anyone who paid flagship prices in 2024. Samsung is expected to expand the One UI 9 rollout to additional countries, though timing for specific markets remains unconfirmed.
If your device is not on the US list yet, the international expansion is reportedly coming. No fixed schedule has been published publicly.
