Imagine every possible pro mode setting combination had a code. This would allow users to easily share their pro mode settings, making it possible for beginners to take pictures like people that have more experience with the pro mode settings.
You can copy paste someone your code and they can enter it in pro mode and have the same pro mode settings as you.
This would benefit content creators and users, the content creators can take images and just put the code in the description of for example the Instagram post or the YouTube video, making it possible for the viewers to just copy paste the code and take pictures with the same settings used by the content creator.
This could also motivate people to experiment with the pro mode settings and build a community around that.
Like that Samsung could see what the most used pro mode settings are (what the users like the most) and maybe update the camera in future phones so that it focuses more on the aspects the users like most ( improve portrait mode, night mode and so on)
