Samsung named it the Alt-Z life that allows the users to switch between two different views of the same app.
This is like a secret vault in your big house where you can store more private things. You can just store any data that are more important or you don’t want others to see.
Presenting the Alt Z Life - a life where your private content, apps and interactions stay private with Quick Switch.
Quick Switch
From main to private mode with a double click
Quick Switch lets you instantly switch between main and private mode. All private apps, images and folders can be accessed or exited by double clicking the side button. You can even switch between two accounts of the same app. It’s the perfect feature for the Alt Z Life.
Content Suggestions
Intelligent suggestions to help you stay private
Basis the identifiers you set, Content Suggestions feature uses AI to intelligently recognize and suggest images that you may want to keep public *(main)or private and lets you move them instantly to the private gallery.
Secure Folder
Where your privacy is safe
Secure Folder creates a private, encrypted space on your Samsung Galaxy smartphone by leveraging the defense-grade Samsung Knox security platform. The Secure Folder is the perfect place to store all the photos, videos, files, apps and data that you want to keep private. You can also add a passcode or biometric lock to keep your data secure from prying eyes
The new updates with firmware versions A515FXXU3BTGF and A715FXXU2ATGK are being rolled out to the Galaxy A51 and the Galaxy A71, respectively. These updates don’t bring the new security patch, though. If you’re a Galaxy A51 or Galaxy A71 user in India, you can check for the update by navigating to Settings » Software update menu on your phone and tapping the Download and install button.
