Samsung is extending its latest security updates to a range of its Galaxy devices in the United States, including the Galaxy Z Fold 5, Galaxy Z Flip 5, Galaxy Z Fold 4, Galaxy Z Flip 4, and the Galaxy S23 FE, alongside the already updated Galaxy S23 series.
Galaxy Z Fold 5 and Z Flip 5 Receive March Security Patch
The Galaxy Z Fold 5 variants in the US have begun receiving the March 2024 Security Maintenance Release (SMR), with improvements targeted at enhancing security for users. The carrier-locked versions of the Galaxy Z Fold 5 are getting update F946USQS2BXBE, while the unlocked models are receiving F946U1UES2BXBE. This rollout is primarily focused on implementing the latest security patches.
Similarly, the Galaxy Z Flip 5’s carrier-locked variant has been updated with firmware version F731USQS2BXBE, echoing the commitment to bolster security. Samsung is expected to extend these updates to unlocked models and advance the security release to the 2023 foldable models globally.
Galaxy Z Fold 4 and Z Flip 4 Get Security Enhancements
For users of the 2022 foldable models, the Galaxy Z Fold 4 and the Galaxy Z Flip 4, the March security updates are initially available for carrier-locked devices, with build numbers F936USQS4EXBD and F721USQS4EXBD, respectively. Samsung has concentrated on delivering the latest security patches in this release, without additional feature updates. Those anticipating the One UI 6.1 feature update may have to wait a little longer.
Security Patch Details for Galaxy Foldable Devices
The March security patch from Samsung addresses numerous identified vulnerabilities, with around three dozen Android OS corrections and nine specific fixes for Galaxy models. This monthly security update might seem modest compared to previous releases, yet it addresses critical security issues that users are encouraged to install promptly.
Users can manually check for the latest security updates via their device’s Settings app.
Galaxy S23 Series Also Secures the March Update
Continuing with its update rollout, Samsung is also deploying the same security patches to the Galaxy S23 lineup across the US. The update, initially released for carrier-locked models last week, has now been made accessible to unlocked Galaxy S23 devices and the Galaxy S23 FE model.
The flagship Galaxy S23 receives an update with a build number similar to that of carrier-locked units ending in BXBD, while the Galaxy S23 FE is being updated with the version S711USQS2BXBF. Samsung’s changelog explicitly indicates that these updates are security-focused, strengthening the devices against potential security threats.
Samsung remains committed to providing timely updates to ensure the security and performance of its devices, reflecting its focus on customer security and experience across its range of smartphones.
