Samsung One UI 9 adds on-device AI Privacy Alerts for apps
Samsung began expanding One UI 9 on September 16, 2026, and the update introduces Privacy Alerts, an on-device AI feature that flags questionable app permission activity such as excessive precise-location access or unnecessary background permissions, then suggests limiting what sensitive data apps can reach. Supported devices listed in Samsung's US rollout notice include the Galaxy S26, S26 Ultra, S25, S25 FE, S24, S24 FE, S23 and S23 FE, foldables from Z Fold8 Ultra and Z Flip8 down to Z Fold5 and Z Flip5, and the Tab S11, Tab S10 and Tab S9 tablet families. Samsung notes an alert does not mean an app is malicious and its AI detection may not weigh every relevant factor, and compatibility lists differ by region, with the Galaxy S26+ missing from the feature documentation despite being among the first phones to get the update. One UI 9 also adds Security Brief, which surfaces malware warnings and unnecessary permissions in Now Brief.
On-device AI is turning privacy protection from manual permission checks into automatic warnings, though uneven device and regional lists show the rollout is still patchy.
