Well here's the thing with cameras. You need to learn how to best use the tool you own. Apple, Samsung, Google, Huawei, LG, etc., all use different cameras in their phones. If you own a Pixel, you learn how to best use the cameras in the Pixel. Just as you need to learn how to use the cameras in iPhone. I won a Nikon DSLR with lenses costing far more than my iPhone 12 Pro Max. My Nikon takes great photos. It also can take really crappy photos. I need to know how to take the best photos with my Nikon, just like I need to learn how to take great photos with my iPhone.
And that's what's wrong with this thread in total. People are expecting a degree of perfection no camera system is capable of. The expectation that all you have to do is point your phone, take a picture and EVERY picture will be perfect is unrealistic and frankly not possible. If you take a bad photo, which ALL photographers, even professionals do, you look at the photo, figure out what didn't work, learn how to avoid whatever went wrong and learn to take better photos.
There's an old saying in photography, "It's not the camera, it's the person behind the camera."
On a final note about 22 pages of this thread. Do you honestly think that's a high portion of the number of people who own iPhone 12? Not even close by a magnitude of millions upon million upon millions of iPhone 12 phones in use today. The number of individual (not repeat posters like you and me) in this thread is actually statistically insignificant in comparison to the number of people out in the world happily using their iPhone 12 cameras.
