Available on Many Galaxy series smartphones, the Secure Folder feature on Samsung Galaxy Note 10 allows users to store private, highly sensitive files in an encrypted environment. The most interesting thing about the Secure Folder is that the files stored inside the folder are completely isolated from the rest of the device and are locked behind biometrics or passwords. For instance, if you’ve stored some files in the Secure Folder, then you will only be able to access them inside the secure folder as those files can’t be viewed from anywhere else on the device.
