Samsung has begun rolling out its security update to the Galaxy Z TriFold, the company’s first and only tri-fold smartphone. The update started in South Korea with firmware version F968NKSS3AZB2 and weighs 528.56MB, according to multiple Samsung device tracking sources.
What’s Included in the Update
The February 2026 security patch addresses 37 vulnerabilities across Android and One UI. According to Samsung’s official security bulletin, 25 fixes come from Google for the Android operating system, while the remaining 12 are Samsung-specific patches targeting components like Samsung Dialer, Settings app, and biometric authentication systems.
The changelog does not mention any new features or UI changes. This is strictly a security-focused update, as Samsung is reserving major software enhancements for the upcoming One UI 8.5 release expected with the Galaxy S26 series launch.
Rollout Timeline and Availability
The update launched first in South Korea on February 23, 2026, following Samsung’s standard phased rollout strategy. The update will expand to additional markets in the coming days, though availability depends on carrier approval and regional schedules.
Users can manually check for the update by navigating to Settings → Software update → Download and install. Note that even when the update reaches your region, it rolls out in stages, so immediate availability is not guaranteed.
Other Devices Receiving the Patch
The Galaxy Z TriFold is part of a broader February 2026 security update wave affecting multiple Samsung flagships. The following devices have also begun receiving the patch:
- Galaxy S25, S25+, S25 Ultra, S25 Edge, S25 FE
- Galaxy Z Fold 7 and Z Flip 7
- Galaxy Z Fold 6 and Z Flip 6
- Galaxy S24 FE
Samsung typically begins security updates with its newest flagships before expanding to mid-range and older devices. This aligns with Samsung’s seven-year software support policy for premium devices, which includes seven generations of OS upgrades and seven years of security patches.
About the Galaxy Z TriFold
Samsung’s tri-fold smartphone represents the company’s most advanced foldable form factor to date. Unlike the dual-screen Galaxy Z Fold series, the TriFold features three connected display panels that fold into a compact device. The device builds on technology showcased by Samsung Display, the company’s panel manufacturing division.
While the Galaxy Z TriFold launched to limited availability and remains difficult to find in stock, Samsung has maintained consistent software support for the device since release. The February 2026 security update demonstrates the company’s commitment to keeping even its most specialized devices secure and up to date.
