What is Samsung Dual Apps?

Samsung Dual Apps is a dual app feature provided by Samsung for users. Its core is to allow users to log in to two accounts of the same app on one device at the same time. This feature is currently mainly implemented through “Samsung Dual Messenger”, which is applicable to social applications such as WhatsApp, Messenger, LINE, Facebook, Snapchat, Telegram, etc. Unlike the traditional “multi-user mode” or “app clone”, Dual Apps does not need to switch users or login status at the system level, but directly generates a “clone version” for supported applications. Users can set parameters such as notifications and interface language for the two accounts separately to achieve true account isolation.
