Galaxy Z Fold3 and Z Flip3 are the latest phones to get October 2021 Android security patch

Sagar, 30 September 2021

Samsung once again became the first company to release a new Android security patch ahead of schedule as it rolled out the October 2021 patch for the Galaxy S21+ and S21 Ultra a few days ago. And now, it's the Galaxy Z Fold3 and Galaxy Z Flip3 that are getting the latest Android security update.

The new build for the Galaxy Z Fold3 comes with firmware version F926NKSU1AUID, and F711NKSU2AUIE for the Galaxy Z Flip3. A detailed changelog of the update is unavailable, but it should bring more to the smartphones than just a new security patch.

The update for both smartphones is seeding in South Korea across different carriers, including KT, SK Telecom, and LG U+. If you haven't received it yet, you can try checking it manually by navigating to your device's Settings > Software update menu.

While the Korean Galaxy Z Fold3 is already receiving the October patch, unlocked and carrier-locked units in the USA are only now getting the September 2021 security update with firmware versions F926U1UEU1AUI4 and F926USQU1AUI4, respectively.
