Overview

• Users report that customized Do Not Disturb exceptions revert to defaults, which can silence calls, messages, app alerts, and alarms.
• SamMobile says it reproduced the problem on its Galaxy Z Fold 7, noting settings were lost after being configured the previous day.
• The issue is tied to the stable One UI 8 build that ships on the Galaxy Z Fold 7 and Galaxy Z Flip 7.
• A fifth One UI 8 beta for the Galaxy S25 series includes a changelog entry claiming to fix the DND reset behavior.
• Owners of the new foldables have not received that patch yet and are advised to double-check DND exceptions or avoid relying on the feature until an update arrives.
