The release of Fortnite is currently in beta, and available only for Galaxy users for a short time. How long exactly? That hasn't been announced. You can sign up for a beta invite to Fortnite on Android by following the instructions here, but before doing so, it's a good idea to make sure the app will even work on your Android phone or tablet. Thankfully, Epic Games has posted such a list. Here it is, in its entirety, directly from Epic's FAQ page.
If you do have a device that's fast enough to run the most popular game on the planet, you can find instructions on how to install it.
The Android beta currently works on these devices.
- Samsung Galaxy: S7 / S7 Edge, S8 / S8+, S9 / S9+, Note 8, Note 9, Tab S3, Tab S4
- Google: Pixel / Pixel XL, Pixel 2 / Pixel 2 XL
- Asus: ROG Phone, Zenfone 4 Pro, 5Z, V

If your phone is not on this list, it might still work assuming if you have the following specs:

- RAM: 3GB or higher
- GPU: Adreno 530 or higher, Mali-G71 MP20, Mali-G72 MP12 or higher
So there you have it. Fortnite, it appears, will more or less be limited to higher-end devices that are capable of handling the game's fast-paced action.
