Shooting on an analog camera already requires a lot of manual work, and the app adds to it by having too many controls. It switching between the settings and controls caused it to brick my iPhone12 which is the first time ever that an app has done that on my phone. The display is not built for a device which has no home button at the bottom like the iPhone 12. If you’re developing an app for a store, at least keep it updated to the last 3 versions of the devices and os design.
