Hi @EcoBubbleUser944 I think the focus increasingly moving to Cloud services and I think unlikely to come back to the flagships. Personally have not used an SD card on a mobile for a little while, though they obviously have their fans. Must be said not the fastest technology though and can be prone to errors. one article on the change at the time here. https://www.androidpolice.com/2021/01/14/samsung-ditches-microsd-card-slot-for-galaxy-s21-series/#:~...
Agree it is advisable not to rely on one cloud service, one review of services here https://uk.pcmag.com/file-syncing-and-backup/3682/the-best-cloud-storage-and-file-sharing-services-f... another option is to use an Flash Drive. some options detailed here https://pocketnow.com/best-microsd-alternatives-galaxy-s22/
I do not work for Samsung or make Samsung Products but provide independent advice and valuable contributions.
