I've not got a Samsung, but on my LG G3, 'Others' is called 'Miscellaneous'. I could be way-off, but 'Others' is likely your system software (which you you don't want to delete!).
BTW, I think you may have it the wrong way 'round in your post - I think your device monitor is showing that you have 11gb free, as opposed to 11gb used.
