iPhone 4S "Other" category taking up 7.5 gbs
What are methods for reducing the space taken up by the other category? I deleted a ton of pictures, apps, and text messages, but the "Other" went up from 6.5 to 7.5 gigabytes. I'd rather not restore my phone; I've had to do that 3 times in the past year for this same reason. Are there any other ways to free up more space?
iPhone 4S, iOS 6.1.4
