When your iPhone camera is not working, take these steps to test it and solve the problem.

1. Test with FaceTime. Perhaps the quickest way to test both front and back cameras is with the FaceTime app. Open the app with a friend and switch between the front and back cameras. It is the best app for testing whether the problem occurs with one or both cameras.
   

2. Quit the Camera application. The problem with your camera may be the Camera app. Whether it's frozen or not loading correctly, quitting the application could be all you need to do.
   

3. Restart the iPhone. While restarting the phone may sound like an unlikely solution, you'd be surprised how many times this resolves problems. When you restart your iPhone, you clear the temporary memory of errors or hung-up apps. While some tech folks joke about turning things off and back on, it fixes many problems.
   

4. Update the iOS software. Apple continuously improves and updates the operating system (iOS) on your phone. Updates to the Camera app are included in those iOS updates. If you haven't updated your phone's iOS software recently, your camera issues may be the result of outdated software. Check to see if your phone has the most current version of iOS that is appropriate for your iPhone.
   

5. Reset the iPhone to default settings without erasing your content. Sometimes you or another app may change settings on your iPhone that cause your camera or Camera app to stop working or malfunction. One way to eliminate this possibility is to reset all the settings on your iPhone. The nice thing with the iPhone is that you can reset settings without losing your data, photos, and other personal documents. It is almost like a factory reset without the hassle of reloading and backing up everything.
