Any app claiming to run PS4 games on a $200 Android phone is obviously fake.
Unlike older consoles (like PS1 or PS2) where a single BIOS file is often enough to start an emulator, the PS4 uses a complex Operating System (Orbis OS). Most current PS4 "emulators" for PC actually require a PS4 Firmware Update file (PUP) or specific decrypted modules rather than a simple BIOS file. ps4 bios download for android
