I just found a button on my phone saying secure folder and it's in my quick settings and I want to know exactly what it is for and how do I use it . Like for example what kind of things do people usually put in it and how to you out stuff in it? Thank u
The Secure folder is a Private space in your phone. You can lock apps, photos and more things inside it. Everything works like normal apps except the fact that it is secured by the lock type of your choice and has some restrictions like you cannot access your regular storage or sdcard from Secure Folder (This is because of Secuirty).
Before you can use the Secure Folder in quicsettings, you have to configure it, like setup password etc. You can access the settings at Settings > Biometrics and Security > Secure Folder.
I hope that clarifies. Still for detail you can visit the link provided by @Jay94.
