Apps using the camera API crash after taking a picture on an iPhone 4S running iOS 7 Ever since I updated to iOS 7 in June, I have been having issues using the camera on my phone in apps other than the default Camera app. Regardless of settings, using my camera in any non-Apple app (such as Instagram or Tumblr) will result in that particular app crashing immediately. I have tried everything to remedy the issue short of a full restore on my phone. I'm convinced it's some sort of low memory or high CPU utilization issue, since iOS 7 seems to be much more taxing on my phone's resources than iOS 6 was. Is there some way to fix this issue without simply buying a newer, faster iPhone?
Rebooting always fixes the problem for me.

As for permanent solutions, haven't tried this myself but this comment has a possible solution (pre-iOS 7 however iOS users have reported success):  http://www.iphoneincanada.ca/how-to/how-to-fix-iphone-camera-roll-crash-and-photos-turned-to-other-in-itunes/#comment-347059180
