[Xiaomi 12S Ultra] Jdorman12:
I have been trying to find mods/tweak the camera. Unfortunately don't know how to hex edit so and bin files so until someone helps, full raw isn't capable unless you use a modified opencamera with camxoverridesettingsOfUltra.txt edit.

echo exposeFullSizeForQCFA=TRUE >> /vendor/etc/camera/camxoverridesettingsOfUltra.txt

Otherwise here are some prop files I have found specific to the 12s ultra. I know these make some good tweaks and don't add multiple at once and write down the ones you do. Lanthanum toolbox or any good prop editor makes it easy.

It took me hours to do this, and I did not write down all the specific things that they do, as some of them didn't have much info. I will try to update the info per prop when I have time, or you guys can post what it does, thanks.

There will be more to come mod wise and tweaks. I wish there was more people attempting to bring out the full capabilities of this camera.
