Samsung Rolls Out Critical April Security Update for Galaxy Foldables
Samsung has officially initiated the rollout of a brand-new software update for its previous generations of Galaxy foldable smartphones. This essential package includes the April security patches and successfully eliminates dozens of newly discovered vulnerabilities. If you own a compatible device, it is highly recommended to install the update as soon as it becomes available in your region.
April Security Patch: What You Need to Know
The latest update specifically targets the Galaxy Z Fold 5, Galaxy Z Flip 5, Galaxy Z Fold 4, and Galaxy Z Flip 4. According to Samsung’s official release notes, this firmware resolves a total of 47 security flaws found in earlier versions of the operating system.
Keeping your device updated is critical for protecting your personal data against emerging threats. Following the recent Samsung One UI 8.5 update delay and March security patch, this prompt April release demonstrates the company’s ongoing commitment to device safety.
Supported Devices and Firmware Versions
Currently, the security patch has been deployed to users in South Korea, serving as the initial testing ground before a global release. The specific firmware versions for the updated models are identified by the following build numbers:
- Galaxy Z Fold 5 – F946NKSS6FZCS
- Galaxy Z Flip 5 – F731NKSS6FZCS
- Galaxy Z Fold 4 – F936NKSS7IZCS
- Galaxy Z Flip 4 – F721NKSS7IZCS
In line with the manufacturer’s standard rollout procedures, users across other international regions can expect to receive this security package over the air within the coming days to weeks.
How to Check for and Install the Update
To ensure your smartphone remains secure, you can manually verify the availability of the new firmware. Simply follow these steps:
- Navigate to the Settings app on your device.
- Scroll down and select Software update.
- Tap on Download and install.
If the update is live in your region, your phone will automatically begin the download process.
Looking Ahead: The One UI 8.5 Beta Program
Security patches are not the only developments happening behind the scenes. Samsung is simultaneously developing the next major iteration of its custom interface. The Galaxy Z Fold 5 and Galaxy Z Flip 5 recently gained access to the One UI 8.5 beta version, which is built upon the Android 16 (QPR2) architecture.
This upcoming software introduces a completely redesigned user interface alongside a suite of new features that participants can thoroughly test prior to the official stable launch. While we eagerly anticipate broader firmware rollouts, such as the Samsung One UI 8.5 beta for the Galaxy Z Fold 6 and Flip 6 rollout, older generations are not being left behind.
Although the Galaxy Z Fold 4 and Galaxy Z Flip 4 are slated to receive the stable One UI 8.5 update eventually, they have not yet been included in the current beta testing program.
