*sigh*
yeah one of the unfortunate things about Google's camera software is that it is designed specifically for their devices, and they have a lot of resources to make their camera software top class.
It's one of the unfortunate side effects of having sovereign tech. A little bit of luxary in exchange for privacy/freedom.
Though the more people like yourself to use this freedom tech, the more devs come to improve the project.
Maybe a solution, for now, is to get a stand alone camera. Maybe the bug is a feature, and you're more in the moment and less distracted when you take photos with it.
