not enough storage space? I deleted every mail
My icloud inbox is empty. I deleted all the mail from the icloud on the desktop browser website version AND from my Iphone 4S. All 3000 inbox mail is gone so why does my Iphone keep telling me that my storage space is full? I only have 400 photos. No video. No games except angry bird. I have a 16GB and my iphone is updated.
iPhone 4S, iOS 9.3.1
