Fortnite on S8 Plus?

I have an S8 Plus and I would like to gamble on Fortnite. However, the game is completely mine even though I have the lowest setting. Do you have any suggestions on how I can get more FPS?

Stop unneeded tasks in memory.

Could be on the Internet but in general Fortnite on cell phones is not so good. I myself have a Honor 10 and there it is relatively good, but only with good Internet connection and in the endgame or if a lot is going on the FPS drop anyway
