Samsung has begun the rollout of the One UI 9 beta for the Galaxy S26 series, featuring enhanced security measures. Key additions include the Auto Blocker with a security report feature and the reinstatement of USB connection blocking in Maximum restrictions mode. The beta version allows monitoring of "unknown" apps, alerting users to high-risk applications and blocking their execution and installation. Users can access the Manage unknown apps section in Settings to view and uninstall sideloaded applications from non-approved sources. This feature aims to improve user experience and security oversight, with expectations for inclusion in the stable release.
