Q: Iphone 5 camera black screen

Hello steliosjamesbar,

After reviewing your post, it sounds like one camera works on the phone but the other is black. I would recommend that you read this article, it may be able to help the issue.

Get help with the camera on your iPhone, iPad, or iPod touch - Apple Support

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  (camera swap icon). 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.

Thanks for using Apple Support Communities.

Have a nice day,

Mario
