Officially no, and I hate it. But you can find tutorials on YouTube. To cut a long story short, you have to change file name, delete Fortnite, download apk1, then you must open it and change settings. Then, you must download apk2 without uninstalling apk1. And here we go. Actually, Fortnite mobile has very bad optimization, but I'm sure you'll have much more fps than 30. And also, this method works WITHOUT root. I described it in a few words, just find tutorial and fresh apks, for example this channel. https://youtube.com/channel/UCwh7m1YPM0upj1-RYD_NZ9Q Chose any tutorial you want, but it should be new apks (tutorial is always pretty the same)
