How to play?
If you don’t own a Samsung Galaxy device, you’ll have to wait a bit before you can start playing. Epic will begin sending out invites after a short exclusivity period for Samsung users expires. Visit Fortnite.com/Android on your phone to request an invite to the beta.
Samsung Galaxy users can exclusively install Fortnite for the next few days and are given the choice to install the Fortnite Installer directly from Epic Games or through Samsung’s Galaxy Store.
All you have to do is go to the Fortnite website and just follow the instructions.
