Samsung continues its commitment to device security with the latest monthly patch now reaching more Galaxy devices across its ecosystem. While many users are eagerly anticipating the major One UI 7 update, the company is ensuring all supported devices remain protected against the latest security vulnerabilities.
US Galaxy S23 Series Now Receiving March Security Patch
Samsung has begun rolling out the March 2025 security update to the Galaxy S23 series in the United States. The update is currently reaching carrier-locked variants of the Galaxy S23, Galaxy S23+, and Galaxy S23 Ultra under the build numbers S911USQS6CYB3, S916USQS6CYB3, and S918USQS6CYB3, respectively. Users of unlocked models can expect to receive the update in the coming days as Samsung continues its phased deployment strategy. This follows last week's initial rollout that prioritized the company's latest flagship devices, including the Galaxy S24 lineup.

Comprehensive Security Improvements
The March 2025 security patch addresses a total of 58 vulnerabilities, making it a significant security maintenance release. Of these fixes, 51 come directly from Google to address issues within the Android core system, with 11 classified as critical and the remainder as high-priority items. Samsung has contributed an additional seven fixes specifically for vulnerabilities that could potentially be exploited on Galaxy devices. While the update doesn't introduce any new features, it significantly enhances device security by patching these identified vulnerabilities.
Expanded Device Coverage
Beyond the Galaxy S23 series, Samsung is extending the March security update to several other device families. The Galaxy Z Fold 6 and Galaxy Z Flip 6 were among the first to receive the patch last week, with the rollout now expanding to include the Galaxy S24 series, Galaxy Z Fold 4/Z Flip 4 and newer models, and the Galaxy A55. As is typical with Samsung's update schedule, availability will vary by device model and region, with some users receiving the update earlier than others.
Looking Ahead to One UI 7
While the security patch provides important maintenance, many Galaxy users are more excited about the upcoming One UI 7 update based on Android 15. Samsung has confirmed that the One UI 7 beta program will be expanded to the Galaxy S23 series at the end of March, following the beta releases for the Galaxy Z Flip 6, Galaxy Z Fold 6, and Galaxy Tab S10 series scheduled throughout the month. Users interested in joining the beta program can apply through the Samsung Members app once it becomes available for their eligible device.
Update Timeline Expectations
The stable version of One UI 7 is scheduled to begin rolling out to devices in April, starting with the Galaxy S24 series. For Galaxy S23 owners, patience will be required as the beta testing phase could last approximately four months based on Samsung's previous update patterns. This suggests that stable One UI 7 for the S23 lineup might not arrive until mid-to-late summer, though exact timelines have not been confirmed by Samsung.
