http://en.m.wikipedia.org/wiki/Special:Uploads  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:
- Move to core as is
- Fold functionality into an existing page. e.g. Special:ListFiles - adding infinite scroll and mobile styling
- Delete from MobileFrontend
- Link to the page from somewhere else in the UI (possibly on the multimedia viewer username  when you open an image to see other images by that user)
