[Galaxy J series 2017] What is the secure folder?
Secure Folder protects your private content and apps, such as photos and notes, from being
accessed by others. Keep your private content and apps even when the device is unlocked.
You can also use multiple accounts on a single device.
Secure Folder is a separate, secured storage area. The data and apps in Secure Folder cannot
be transferred to other devices. Attempting to customize the operating system or modifying software
will cause Secure Folder to be automatically locked and inaccessible.
Before saving data in Secure Folder, make sure to back up a copy of the data in another location.
