Developers @Lunarixus, Dyneteve and AnanJaser1211 have managed to boot the read-only images from a Galaxy S22 Ultra on a Pixel 6 Pro, booting the latest OneUI 5.1. This is NEITHER any port NOR any GSI as the system and product are untouched. Images are directly flashed straight up from Galaxy S22 Ultra.
Google Camera (GCAM) works perfectly straight away downloading from PlayStore. Samsung adaptive codec along with Dolby Audio with SoundAlive fully functions in this Pixel 6 pro too. Calling works fine along with audio but in Emergency mode only yet
Bluetooth, NFC, UWB, Wi-FI, Audio, Screen Resolution switcher, HWC, etc. Almost everything works including SSC (Samsung Seamless Codec).
RIL and some issues exist with the touchscreen.
It might be released to Pixel 6 pro users just for LOLz if RIL gets fixed.
