Samsung's One UI 9.5 will introduce an app lock feature that enhances user privacy by allowing applications to be secured with a PIN or biometric authentication. Users can activate the app lock by pressing and holding an app icon in the app drawer, where a padlock icon will appear. Accessing locked apps will require biometric verification or the device's screen lock, and once locked, the app's widgets and shortcuts will be removed from the home screen, with notifications concealed. However, content from locked apps will still be accessible to other applications with prior permissions. Currently, Samsung devices offer the Secure Folder feature, which has limitations, as it creates a cloned version of the app while leaving the original accessible. The new app lock feature is similar to the one introduced in Android Canary 2608, indicating a possible influence on Samsung's development.
