Why is the other section on my iPhone so high

Why is the other section on my iPhone taking up 4.77 GB? I only have 16gb so that is a HUGE problem. I already restored it once from backup and it even takes up more after! Please help me.

Jailbroken? My iphone was jailbroken and the others section was taking 6.2 GB. Restore it

  • Why is my other section so large? Here is a screenshot of my iphone 5 storage. As you can see, the "other" section takes just about 40% of all of my space. Which stinks because I barely have space for anything else. Can anyone tell me why this could be so large? Or what I could to reduce this?
  • Why is my music not showing up in the artist section of my iPhone? I just started adding music to my Iphone 5 and quite a bit of the music will not show up in the Artist section. After searching for it I can usually find what I was looking for in either the Album or Song section, but I find it kind of annoying to have to search so hard just for music. Any idea what's causing this?
  • Why does my imported videos go to the picture section on Windows 8? I Uploaded some Videos on my Desktop, whenever i connect my Iphone 4s to the Computer, it takes me to the Pictures section, and my videos end up in the Pictures section, which is a problem because my video editor thinks that I'm trying to upload a picture not a video. I have windows 8!
