With a patch of Bug #62598 (https://gerrit.wikimedia.org/r/#/c/143778/) we hide the link to page Special:Uploads for users, who aren't autoconfirmed, form MobileMenu.
I think this isn't the best design for this. The user can still upload images on desktop and maybe want to use them when editing with mobile. We prevent him the simple access, because he is not an autoconfirmed user (and in future maybe other rules, too) to a page, which can only show him his uploads. I think we should show him the link (The page is still accessable directly); the upload button is hidden, when the user haven't the permission to upload (not autoconfirmed) after this change: https://gerrit.wikimedia.org/r/#/c/143822/.
