Samsung’s Galaxy Z Fold 6, Z Flip 6, Z Fold SE, Z Fold 4, and Z Flip 4 are receiving the One UI 8-based October 2025 update. It also marks the major One UI 8 update’s expansion to South Korea for the 2022 foldable phones.

It’s the last day of October 2025, and Samsung didn’t forget to offer the latest security update to the Galaxy Z Fold 6, Z Flip 6, Z Fold SE, Z Fold 4, and Z Flip 4. The new patch follows the major rollout of the One UI 8 software update.

Samsung’s October update has fixes for 34 CVE and SVE items. The software still lacks some important improvements due to Google. The Android bulletin will now bring an extended set of CVEs for a broad user base.

While it’s a fresh start for Korean Galaxy Z Fold 4 and Flip 4 users, the October patch is a crucial development for the Fold 6, Flip 6, and Fold SE. It will bring a notable improvement in everyday usage as well as key functions.

You can access the latest software through Settings > Software update > Download and install. The October patch can be installed over cellular, but the One UI 8 for 2022 foldable is a nearly 3.5 GB update, requiring an unmetered connection.

Note that the update has started to roll out in South Korea; expansion would take some time.

Also, make sure to back up your data before installing the OTA and keep your phone’s battery charged above 50%. Don’t panic if you see a sudden drop in battery, as it takes about a week for the new software to optimize.
