I am having issues with my camera. The front camera is working just fine, but the option to flip it, it black. Any suggestions for fixing this? I have reset my phone multiple times trying to fix it and it hasn't worked

See this, If the camera or flash on your iPhone, iPad, or iPod touch isn't working - Apple Support and if necessary, contact Apple Support.

The link I posted is all that is available to troubleshoot the camera. If that does not work, then contact Apple Support.

My rear cam also started to have problems after the latest update. it’s shaking real bad and making noises coming from the rear cam like a shutter problem

I also have this problem and tried all of the suggested fixes but nothing works...

Then you have to contact Apple Support. Use the link at the top of the page here.

Same problem with my iphone X-the Face ID works but facetime will not work with camera facing me or and camera app screen is black when in selfie mode.
