Back in 2016, a new app/feature of the Galaxy Note 7 was an app called Secure Folder. The idea behind the app is that users could put things inside of this folder and it will be protected from prying eyes and would only be accessible if the user were to authenticate themselves using their fingerprint.
It was later suggested that Secure Folder could be coming to the Galaxy S7/S7 Edge, and fast forward 2 months later and it looks like the app has indeed arrived for Samsung’s 2016 flagships. According to Samsung, “Secure Folder leverages the defense-grade Samsung Knox security platform to create a private, encrypted space on a Samsung Galaxy smartphone.”
“Apps and data moved to Secure Folder are sandboxed separately on the device and gain an additional layer of security and privacy, thus further protecting them from malicious attacks.” At the moment it seems that it is only compatible with both the Galaxy S7 and S7 Edge, but it should be noted that users will also be required to have Android 7.0 Nougat on their phones as well, so if you haven’t updated to Nougat yet then you will need to before downloading it.
The app isn’t available from the Google Play Store and users will need to go to Galaxy Apps if they want to get their hands on it.
