HELP! My phone takes pictures but won't save them.

Question

I have an iPhone 4, when I updated to iOS 7, the camera stopped working. Screenshots and taken pictures show up on the bottom left of the camera screen, showing that they were taken, but don't exist in the camera roll when I click on them (or in any other folders). As for video, the blinking red dot appears and goes away instantaneously, then the app crashes.

Also sync again to transfer any recent purchases to your iTunes library, then restore as you did before (by clicking on the name of your phone on the left side of iTunes, going to the Summary tab to the right and clicking on Restore).  But this time, when you go through the setup assistant at the end of the process select Set up as New iPhone (see image below).  Then take a photo and test whether or not you can see it now.  If not, you'll have to make an appointment at the genius bar at a nearby Apple Store.
If it's working now, turn on iCloud syncing for calendars, contacts, etc. again (in Settings>iCloud) to recover your iCloud data (if prompted, choose merge), and sync with iTunes to transfer your apps, music, and other iTunes media back to your phone.  You can sync any videos back to your phone by selecting to do so on the Movies tab of your iTuens sync settings., and put your imported photos into a folder and sync that back to your phone by selecting to do so on the Photos tab.
