The localization team wants us to change the id when we change the string. So you'll have to change emtpy-text to empty-text-v2 or something like that.  And unfortunately, that requires changes in the JS.  (Or in the HTML).

Also, I think that this string no longer makes sense with "to the memory card" in the string. Please change it so it just says "Download or record videos".  

Or, just leave the string unmodified and leave the wording change for another bug.
