The feature is as amazing as the name itself ;)
As we previously had secure folder feature in midrange and flagships, Samsung has done it even better and more accessible!
There are basically 2 features to it.
1) Quick switch
By this feature you can quickly switch between. the private and public version of the same app. by double clicking the power button!
There's also a private play store in the secure. folder so the apps you install In the secure. folder won't show up in the public app drawer.
Isn't it cool?
2) content suggestion.
There is a new app in the secured folder which is called content suggestion Which features the content that you don't want others to see in your gallery!
