Samsung Galaxy Z Fold 5 and Z Flip 5 Receive January 2026 Security Update
Samsung has initiated a new software rollout for its 2023 flagship foldable smartphones. The Galaxy Z Fold 5 and Galaxy Z Flip 5 are now receiving the January 2026 Android security patch, marking the first major update of the new year for these devices.
Update Details and Rollout
The update delivers the latest security maintenance release, which addresses a total of 55 security vulnerabilities identified in the previous version of the operating system. This patch is crucial for protecting user data and device integrity against potential exploits.
Currently, the update is available in Samsung's home market of South Korea. The Galaxy Z Fold 5 update carries firmware version F946NKSSFZA1, while the Galaxy Z Flip 5 update is approximately 385.52MB in size with firmware version F731NKSS5FZA1.

Future Software Expectations
This security update arrives as anticipation builds for more substantial software upgrades later in the year. Industry reports suggest Samsung may release a major update to the Galaxy Z Fold 5 and Z Flip 5 in the coming months, likely bringing One UI 8.5 based on Android 16 QPR2.
One UI 8.5 is expected to introduce a refreshed user interface with improved aesthetics, greater customization options, and enhanced usability features. Such an update would represent a significant mid-lifecycle software boost for these foldable devices, extending their functionality and user experience beyond typical security patches.
Conclusion
The deployment of the January 2026 security patch for the Galaxy Z Fold 5 and Z Flip 5 demonstrates Samsung's ongoing commitment to supporting its premium foldable lineup.
