To find the Secure Folder on an Android device, especially on Samsung phones which commonly have this feature:

• Swipe up from the home screen to open the app drawer and look for the "Secure Folder" app icon to open it.
• If you can't find it, use the search bar at the top of the app drawer by typing "Secure Folder" and select the app when it appears.
• Alternatively, access it via Settings by going to "Biometrics and security" (or "Security and privacy"), then "More security settings," and selecting "Secure Folder."
• If Secure Folder is hidden in the app drawer, go to Secure Folder settings and enable the option "Add Secure Folder to App screen" to make it visible.
• You can also open Secure Folder using Google Assistant by saying "Open Secure Folder," then entering your password or pattern.
• Additionally, remapping your device's side key (power button) to open Secure Folder is an option for quick access.

This feature allows securing files, apps, and data separately, enhancing privacy and security on your device.
