Install Android Oreo for Dual Messenger
The Galaxy S7 Oreo update comes with Dual Messenger, a feature that's currently available on flagship phones like the Galaxy S8 and Galaxy Note 8, but is slowly spreading to other devices via Android 8.0.
If you aren't familiar with the company's Dual Messenger solution, it allows you to use two accounts for the same messaging application on your Galaxy S7, Galaxy S7 Edge, or Galaxy S7 Active.
So once you get Android Oreo installed on your phone, head into your Settings > Advanced Features > Dual Messenger. There, you'll find all of the apps that support Dual Messenger.
Popular apps like Facebook, WhatsApp, WeChat, Viber, LINE, and Skype all work with the Dual Messenger platform.
