Any ideas what we have to do?

iOS, one ui,  android,

I guess you want to install IOS in your S9 .
First of all you need to unlock the BOOTLOADER of your device and install any custom recovery .

Then search the net for IOS like roms or IOS modded roms for S9 . Download any of them and just flash it .
It's that simple .
