A separate, hidden space on your own phone
Secure Folder keeps sensitive photos or apps in a separate space that is fully isolated from your regular gallery and app list, so someone browsing your phone cannot even tell it exists.
Good habits for using it
Set a lock method different from your main phone unlock method for extra separation, and consider backing up Secure Folder content separately, since it is excluded from some standard backup flows by design for privacy reasons.
Frequently Asked Questions
Is Secure Folder content included in a regular phone backup?
By default it is generally excluded from standard backups for privacy, so check your specific backup settings if you want Secure Folder content backed up as well.
What happens to Secure Folder if I factory reset my phone?
Content inside Secure Folder is generally erased along with everything else on a factory reset, so back up anything important beforehand if you plan to reset the device.
