October 2026 One UI 9 update arrives for Galaxy S24 Ultra

Samsung’s latest October 2026 security update has just gone public for the flagship Galaxy S24 series. The month is about to end in a couple of days, but the company has started patching its popular flagship lineup released in 2024.

Users of Galaxy S24, S24+, and S24 Ultra are the first to receive the October 2026 security update in South Korea. The Fan Edition, Galaxy S24 FE, could join the party with the mainstream models in the next few hours or days.

Note that this is an initial rollout, which could take a few days to go global. At present, only Korean consumers are getting the over-the-air update. Expect up to 83 patches on the base and Plus, and 79 on the top tier Ultra version.

Build versions:

• S921NKSS6EZJ1: Galaxy S24
• S928NKSS6EZJ1: Galaxy S24+
• S928NKSS6EZJ1: Galaxy S24 Ultra

Samsung has recently released the Android 17-based One UI 9.0 update. The broader expansion is already underway, but the company went ahead and dropped the first security booster for the flagships back home.

One UI 9 already improved security and privacy status, but the October patch was absent. Thanks to this minor OTA, users of the three flagship phones are receiving the latest Android and One UI patches detailed this month.

A software update notification will pop up as you use your device. Meanwhile, you can trigger the update manually to speed up the process. To do so, open SETTINGS > SOFTWARE UPDATE > DOWNLOAD AND INSTALL.
