ArtemisssMoon I posted the codes for the sharing of filters and LUTs and it’s extremely simple. When sharing a filter or LUT, a zip file gets stored at a website owned by NOTHING. This web address is then converted into a QR code that is shared and decoded by other phones. When decoded, the receiving phone gets the URL and downloads the ZIP file with an image and a .JSON file with the presets. It might also have a LUT attached.
It’s quite simple really and would be very simple to roll out to all phones. Also, you get share from whatever Google drive that you wanted.
I am tempted to recompile NOTHING’s camera APK to allow this (sharing on all phones) but my holiday ends in a few days and I won’t have time.
