To fix your iPhone camera, you should close and reopen the Camera app, as well as restart your phone and make sure it’s updated to the latest iOS. If this doesn’t work, you could try resetting your iPhone to its factory settings — back it up first so you don’t lose all your data — or contact Apple for further support.
