Although it's not supposed to be out until tomorrow, you can download and install the Fuji Xapp for Android & IOS - see the play store (Android) or the app store (Ios) to find it.
I just installed it on my Android phone and it worked OK. I was able to connect and take a picture remotely. I also backed up my settings. I'm not sure what settings are included, but I hope all of them.
