- Android's new security feature, app quarantine, is set to enhance the operating system's defenses against potentially harmful applications.
- App quarantine on Android 15 will impose restrictions on quarantined apps, such as disabling notifications, stopping ongoing activities, and limiting communication with other apps.
- The QUARANTINE_APPS permission is tightly controlled and reserved for the system's verifier app or entities with the same digital certificate as the operating system.
- The official rollout timeline for app quarantine remains uncertain, with no manual method for users to quarantine apps currently available.
- User interface enhancements are expected when app quarantine becomes available, providing clear information to users when launching a quarantined app.
