    Enhanced Now nudge
    Now nudge provides helpful suggestions in more places throughout your Galaxy experience.

    Location access transparency
    Stay on top of your location privacy. A blue indicator will appear at the top of the screen when an app accesses your location. Tap the indicator in the quick panel to see which app it is.

    Stronger security and privacy protection
    Alerts will appear in your Now brief to let you know about risks from malware, apps from unknown sources, unnecessary permissions, and other issues that may put your security and privacy at risk. Apps that have been identified as malicious or vulnerable will be blocked from opening until you make a decision about whether to remove them.

    AI privacy alerts
    Get help protecting your personal data. AI will monitor how apps use permissions and notify you about unnecessary access to your personal data.
