Why won’t my front/ facing camera work?

My camera will. not. work. I have an iPhone7, and recently it just stopped working. I tried the Normal camera, which just displayed a black screen. I then switched over to another app that uses a camera and no dice. I have tried everything from cleaning the camera to restarting my phone at least three times, but had yet to yield any results. If you have experienced anything like this and managed to fix it, please text me the details at ***.

Thank you so much!
