Had the S8, then upgraded to S9, then the S20 then the S20+ and finally the S20 Ultra.... at the time of upgrading to the Ultra, 2 weeks ago, I could have gotten the S21 series device, but I refuse to because of the lack of SD card.
I do not want to rely on another service (cloud storage) for my files and photos. I want the ease of just popping a card into a new phone as simply as just moving a book from one shelve to another! This cloud storage option is just a lure to later charge us for storage. I'll not fall for it, and think I'll be rocking this S20 Ultra ( which by the way is a awesome device) for awhile yet.
