Phone camera not working

@moanas you have not told us which camera has failed. The very first thing you want to do is to try using your camera in Safe Mode. If it works in safe mode, you know that the issue is a Third-Party App that prevents access to your camera. You will have to uninstall that software.

To enter Safe Mode, hold the power button, then press and hold the "Power off" option on the screen until the "Reboot to safe mode" prompt appears. Select OK to restart in safe mode

Now, if it does not work in safe mode as well, it could very well be that the camera module has failed. Since iFixit does not yet have any guides for this, use something like this video to work on replacing the camera module.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has the same issues with their device. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
