My iphone has something wrong- other is taking up almost 6 gig

So I have an iphone 4. The category "other" is taking up literally All MY SPACE. I've had to delete all my music, apps, only have a few pictures, not too many contacts or anything like that, yet "other" keeps eating up more and more space. It started taking up around 5gig and now it's taking up almost 6gig. It's making me hate my iphone, since there's no room for even 5 songs anymore. What could this be?

"I had the same problem, and I've found a solution.

You don't need to reset the phone or install any apps to sort it out.

The 'other' space is the area where things like text messages, emails, documents, etc are stored. It is also where data from apps are stored; things like settings, it's web cache, etc.

All these things are backed up when you back-up the phone, which is why it's still there when you restore from a back-up.

You'll never get rid of it completley, but you can get rid of big chunks of it.

My phone uses iOS 6, I'm not sure about earlier iOS versions.

1. Make sure your phone and apps are synced in iTunes.

2. If possible, make sure you have backed up or copied off any documents or data you might need, as you will loose it. A lot of apps allow you to email documents and data.

3. On the phone, go to Settings/General/Usage. You should find a list of all the apps. The list is mainly 3rd party apps, not apps that come with the phone.

4. On the right hand side, is a list of the total storage space the app is using including the app inself. The list is also handily listed in decending order of size. If you tap on on one of the apps on the list, it shows you how much space is being used by documents and data. You also have the option to delete the app.

5.To delete the app, simply tap on Delete App. The app is deleted, and so is the data which is stored in the 'other' area. Repeat for other apps if neccesary.

6.To re-install the app(s), plug it in to your iTunes and re-sync your phone. The app(s) are re-installed with no data taken up in the 'Other' area.

This worked for me. I had one app that was taking up 2 gig of space in the 'Other' area alone. I did exactly what I've described, and cleared off a chunk of space."
