A Microsoft file hosting and synchronization service.
Hello,
Please open OneDrive > Settings > Camera backup > Back up device folders, and make sure Categorize is enabled.
Keep in mind that this setting applies to NEW backups. It will not automatically reorganize photos already uploaded to Camera Roll.
I would also like to clarify one thing.
Are these actual folders visible in Samsung's My Files app, or are they albums you created in Samsung Gallery?
The distinction matters because OneDrive does not necessarily preserve Samsung Gallery's album organization.
