Hi MoonJ.
I tried steps 1-3 and these have not resolved the issue. For step 4, a walk-in visit to my local apple store caused some confusion and a pricey repair/replace option was suggested that was not guaranteed to work, as my Phone was just out of warranty when the new OS was installed.
I do believe this could be related to the latest iOS as the timing seems very coincidental, therefore I am reluctant to spend money on this issue until there is a reasonable argument to do so. The reason that I brought this problem to the Communities page is that it doesn’t appear to be one of those run-of-the-mill issues that already has plenty of online coverage, even the Apple support pages don’t describe this issue or give any solutions.
As a student, I regularly use my camera in seminars and lectures, this is proving difficult at the current time as this problem persists. I hope there are other people out there with the same issue that are able to replicate the issue that I am experiencing and perhaps find/suggest a solution.
