It's the Device Care widget summer. It should have it. I th8nk I stacked 5 or so widgets on the same space. My best was 5.4GB after the update. But that 4.9GB is now the lowest.
I suppose so. And I think it starts at 256GB. If you're getting one look out for the last push promos next month or here in the Members App. You could still snag free 1 yr care+ and storage bump.
