Why are my front and back camera black?
I bought an iPhone 7 Plus off of eBay and once the phone was shipped, turns out that the iPhone’s front and back camera do not work. They both are black when I open the camera app. FaceTime, my screen is just blank. On Snapchat , it says “Sorry, we can’t access your camera.” Any clue what’s wrong and what I can do? Maybe a replacement? I’m not sure.
