So it looks like you're right about the pixel binning. These phones default to the pixel binned output since the quality of the full resolution images is more prone to degradation. My S24 Ultra's 200MP sensor uses a 16-in-1 binning method to produce 12.5MP images, while the 50MP sensor uses a 4-in-1 method to produce 12.5MP. And I tested a few other apps which also only allow for 12.5MP default pixel-binned resolution.
Thanks for your patience with this and at least we now have the funationality we need for the photogrammetry system. When I'm out of the field, I'll test if the resolution is sufficient for our purposes and let you know if we're able to use your app to drastically advance how biologists document species!

I understand what everyone is saying about pixel binning But on my S24 Ultra, at least with the latest version of the Samsung camera app, when you select the 50 megapixel option, the output is not binned to 12 megapixel.
Please see attached. The image is 38 megapixel because it's in a 16 to 9 aspect ratio instead of four to three which would result in the full 50 megapixels

So you understand that the manufacturer (Samsung) can do whatever they want with their app and it will work on their smartphone.
Well, I think there was something with the moon and a telephoto lens, or am I mistaken? (how beautifully you can see the moon and every crater)
You did it yourself (Samsung or another manufacturer), you produced it, you wrote all the code for a given smartphone, and somehow it works. If it didn't work in Samsung's app, they would probably fire the entire team responsible for it.
This is just my insignificant opinion.

I'm not certain of the details either, but some explanation at https://www.androidauthority.com/what-is-pixel-binning-966179/ . Basically more mega pixels in an image isn't necessarily better beyond a certain point.

Hope it goes okay. Either way it seems a useful feature (and bug fix) to have added to Open Camera.

Hi, please see reply at https://sourceforge.net/p/opencamera/discussion/photography/thread/6b223428b3/?limit=25#4930/fd33 . Note that what a device allows for third party camera applications doesn't have to match what they expose for the built-in camera.
