Samsung's new AltZLife feature lets users create a 'Private Mode' for supported applications
Stock Android still doesn't let you run two instances of the same app, forcing users to look towards third-party solutions such as Parallel Space. Thankfully, some Android Forks offer the functionality. Samsung has taken that concept a step ahead by allowing users to create two separate profiles for supported applications.
AltZLife lets you create two distinct profiles, namely, Regular Mode and Private Mode. The former is meant to be used as your daily driver with your regular suite of applications. The latter is intended for more sensitive information that needs to be kept from prying eyes. For example, one could use an instant messaging app linked to a work phone number in Regular Mode. The Private Mode instance of the same app can be bound to a personal number. This feature will come in handy for those who juggle between different social media profiles.
Samsung has also made it relatively easy for users to switch between the two instances of an app. Double-tapping the power button when inside a supported app will let you seamlessly switch between the two modes. You'll also be required to input a password/PIN/pattern every time you switch between the Regular and Private Mode of an application.
It is unclear if all apps will support the functionality upon launch. Samsung's material around the subject seems to indicate that only a handful of apps will be compatible. Samsung Knox encrypts all of the apps that operate under Private mode (and the data they generate). While that ensures ironclad security for the data in question, you also run the risk of losing the functionality should you ever decide to root your phone.
