How to clear up the other space on an iphone?

I have literally NO room on my phone left. And 9.4 GB is taken up by the "Other" section and its really bugging me as to how much space it's taking up. How can i clear it up?

I would go through and delete some pictures you may have, another big thing would be some videos you may have in your camera roll. I also would also recommend deleting apps you may have that you do not use. Those are the first options that I have done to opening up some space, of course you can always remove and songs or other media you have on the phone.
