My question about the Galaxy Camera has still not been resolved. It has changed somewhat but still not working properly. When I take a picture no pictures appear in Gallery or My Files, only the frame. But pictures from WhatsApps do appear in the Gallery. I've contacted Samsung support and after taking over the phone still can't solve the problem.
The Community couldn't solve this one, ie camera not saving pictures. I contacted Samsung Support and spoke to a technician (three times). The last one managed to solve the problem - I don't know how but he took remote control of of phone and uninstalled Alfred Camera app and did other things. I don't know if that was the source of the problem but it is now working fine.
