Thank you. Im not sure what the solution was but I closed down all open apps, updated all apps in need and then sort of forgot about the issue as all the apps were updating. Next thing I know, I opened Snapchat to check a message and noticed the camera was fine so I checked the phones camera and everything was back to normal. So I cant say which step fixed my issue but upon following your steps it was fixed, thank you. The S8 remains the best.!
