Q: iPhone 5 camera

Hello Sara8800,

Thanks for using the Apple Support Communities!

From your post, it sounds like you are seeing a closed sense or black screen using the rear camera on your iPhone. If this is the case, I would suggest working through the suggested steps in the following article to help resolve this issue.

You see a closed lens or black screen

If you see a closed lens or black screen when you open the Camera app, try these steps:

1. Make sure that there’s nothing blocking the camera lens. If you’re using a case, try removing it.
2. Force the app to close, then open the Camera app again.
3. Restart your device, then open the Camera app again.
4. If your device has a front and rear camera, try both cameras by tapping  . If you see the closed lens or black screen on only one camera, take your device to an Apple Retail Store or Authorized Service Provider for more help.

Have a great day!
