Camera app issues with front camera

Front facing camera issues. Camera app is missing option for front facing camera which was there only a week ago. Last update seemed to cause an issue. I went to access front camera and app froze and wouldn't work and had to restart phone. Similar issue using snapchat and trying to access front camera. I had this exact same problem before after water damage but the icon in the camera app came back.

What is wrong with my phone and how can it be fixed? I tried clearing camera data but it did nothing. Please help.
