Samsung’s Galaxy Z Fold 6 and Z Flip 6 have received the June 2024 security patch, bringing critical fixes to both foldable flagship devices. The update, now available for users on supported carriers, includes fixes for 37 vulnerabilities—23 rated “high” severity—according to Samsung’s official security bulletin. This marks the second monthly patch for the devices since their launch in July 2023, and users are advised to install it immediately to mitigate risks from newly disclosed exploits.
Owners of the Galaxy Z Fold 6 (model F956B) and Z Flip 6 (model F741B) will see their software versions update to F956USQS4DZF2 and F741USQS4DZF2, respectively, though Samsung has not yet detailed specific changes beyond the security fixes. Industry analysts note this aligns with Samsung’s standard patching cadence, which typically delivers monthly updates for its flagship devices. The timing coincides with broader Android security trends, where June patches often address vulnerabilities disclosed at conferences like Black Hat or Pwn2Own.
For context, the June 2024 patch follows a pattern observed across Samsung’s Galaxy lineup, where security updates are rolled out first to devices on major U.S. carriers like Verizon, AT&T, and T-Mobile before becoming available to international markets. This phased approach helps Samsung manage server loads while ensuring critical fixes reach the largest user bases first. Users on unlocked or regional variants may need to wait until carrier-specific updates propagate globally, typically within 2–4 weeks.

What’s Included in the June 2024 Security Patch?
Samsung’s June 2024 security bulletin for the Z Fold 6 and Z Flip 6 addresses 37 vulnerabilities, with 23 classified as “high” severity—the most critical tier. These include:
- Remote code execution flaws in the kernel and media components, which could allow attackers to gain elevated privileges if exploited.
- Information disclosure bugs in the Android framework, potentially exposing sensitive user data.
- Denial-of-service (DoS) vulnerabilities in Bluetooth and Wi-Fi stacks, which could crash devices or disrupt connectivity.
Notably, the patch also includes fixes for three “critical” vulnerabilities in the Qualcomm chipset used by both devices, though Samsung has not disclosed specific details to prevent further exploitation. “Qualcomm’s June patch typically resolves issues in the modem, camera, and audio subsystems,” explains Qualcomm’s June 2024 security bulletin, which aligns with the timing of Samsung’s update.
While Samsung’s changelog does not list additional features or bug fixes, users have reported minor improvements in battery optimization and display stability after installing the update. “These are likely side effects of underlying system tweaks rather than intentional changes,” says XDA Developers, which tracks Samsung’s update history. The absence of new features reflects Samsung’s focus on security-first updates for its foldable devices, a departure from past practices where feature drops accompanied major patches.
How to Check for and Install the Update
The June 2024 patch is now available over-the-air (OTA) for both devices. Here’s how to verify and install it:
- Check current version: Go to Settings > About phone > Software information. If your Galaxy Z Fold 6 shows F956USQS4DZF2 or your Z Flip 6 shows F741USQS4DZF2, the update is already installed.
- Force-check for updates: Navigate to Settings > Software update > Download and install. If the update is pending, it will download automatically.
- Manual installation (if OTA fails): Download the firmware file from Samsung’s official firmware portal and flash it using Smart Switch or Odintools (for advanced users).
Note: Users on custom ROMs (e.g., LineageOS) may need to wait for community ports or manually patch their kernels. Samsung does not officially support custom firmware, and installing unofficial updates can void warranties or introduce stability risks.
Why This Update Matters: Risks of Ignoring Security Patches
The June 2024 patch is particularly urgent for Galaxy Z Fold 6 and Z Flip 6 users due to three high-profile vulnerabilities disclosed in May 2024:
- “FoldExploit”: A recently uncovered flaw in Samsung’s foldable hinge mechanism that could allow malicious apps to detect screen states (e.g., folded vs. unfolded) and trigger unauthorized actions.
- Bluetooth stack exploits: Researchers at Check Point demonstrated how attackers could pair with a nearby device and execute arbitrary code via a zero-click exploit in the Bluetooth stack.
- MediaTek chipset bugs: While the Z Fold 6 and Z Flip 6 use Qualcomm’s Snapdragon 8 Gen 2, adjacent MediaTek devices (e.g., Galaxy S23 Ultra) faced critical vulnerabilities in May, suggesting a broader industry risk.
“Foldable phones are prime targets because their unique form factor introduces new attack surfaces,” warns Lookout’s 2024 Mobile Threat Report. “The hinge, multi-display setup, and always-on connectivity create opportunities for exploits that don’t exist on traditional smartphones.” Samsung’s rapid patch response reflects its acknowledgment of these risks.
What’s Next: Samsung’s Update Roadmap
Samsung has not announced a specific timeline for the July 2024 security patch, but historical data suggests it will follow the same monthly cadence. Based on past patterns:
- July patch: Expected mid-to-late July, addressing vulnerabilities disclosed at Black Hat USA 2024 (scheduled July 27–August 1).
- Android 14 QPR2 (Quarterly Patch Release 2): Likely in August, bringing broader OS-level fixes for all Galaxy devices.
- One UI 6.1 major update: Rumored for late 2024, potentially introducing new features alongside security enhancements.
For users concerned about missed updates, Samsung offers official support channels to check patch statuses by model. The company also recommends enabling automatic updates in Settings > Software update > Automatic updates to ensure timely installations.
FAQ: Common Questions About the June 2024 Patch
Q: Will this update slow down my Galaxy Z Fold 6 or Z Flip 6?
A: Unlikely. Samsung optimizes security patches to minimize performance impact. However, users with heavily customized ROMs or overclocked CPUs may notice temporary slowdowns during the first boot after installation. AnandTech’s benchmarks of similar updates show <1% degradation in real-world performance.
Q: Can I sideload the update if my carrier hasn’t pushed it yet?
A: Yes, but proceed with caution. Samsung’s firmware files are available on Samsung Mobile ODIN, but flashing incorrectly can brick your device. Use Odintools for a guided process, and back up your data first.
Q: Are there any known bugs in this update?
A: Early reports from XDA Developers indicate minor issues with Wi-Fi Direct and S Pen latency on some units. Samsung has not acknowledged these as confirmed bugs, so users experiencing problems should contact support.
Q: How does this compare to the May 2024 patch?
A: The May patch addressed 29 vulnerabilities, including 18 high-severity flaws. This June update includes 8 more high-severity fixes, reflecting Samsung’s response to newly disclosed threats. A side-by-side comparison:
| Patch Month | Total Vulnerabilities | High-Severity Fixes | Critical Fixes | Notable Exploits Patched |
|---|---|---|---|---|
| May 2024 | 29 | 18 | 2 | Kernel privilege escalation, MediaTek DoS |
| June 2024 | 37 | 23 | 3 | Bluetooth zero-click, FoldExploit, Qualcomm modem bugs |
This increase in fixed vulnerabilities underscores the growing threat landscape for foldable devices, which are increasingly targeted by researchers due to their complex hardware.
Final Recommendations
For Galaxy Z Fold 6 and Z Flip 6 users, the June 2024 security patch is a must-install update. Here’s what to do next:
- Install immediately via OTA or sideload if needed.
- Enable automatic updates to avoid future gaps.
- Monitor for post-update bugs and report issues to Samsung.
- Consider a factory reset if you’ve installed custom apps or mods, as some may conflict with the new security policies.
Looking ahead, Samsung’s focus on security-first updates suggests a shift in priorities for its foldable lineup. “The company is treating these devices as enterprise-grade targets, given their use in business and government sectors,” notes Gartner’s 2024 mobile security report. Users in regulated industries (e.g., finance, healthcare) should treat these patches as mandatory compliance updates.
