http://en.m.wikipedia.org/wiki/Special:Uploads [1] was an artifact from the mobile uploads days and with the removal of Special:UserProfile it becomes an orphan page not being linked to from anywhere.
The page is an infinite scrollable list of all the things you've ever uploaded, a feature that doesn't seem to exist elsewhere on mediawiki.
Depending on whether the page is useful or not we have the following options:
1) Move to core as is
2) Fold functionality into an existing page. e.g. Special:Upload
3) Delete from MobileFrontend
4) Link to the page from somewhere else in the UI (possibly on the multimedia viewer username [2] when you open an image to see other images by that user)
