Hi This has happened twice now and both times I have missed a great photo op. I press the home button and then try swiping the camera icon up to take a photo. Nothing happens so I try over and over. No change. I can't even swipe the control centre up when it does this. To fix, I have to unlock the phone and then it starts to work from the lock screen again. Please could you tell me if this has been mentioned so far as another ios 8 bug or is my iPhone 6 broken? Thanks.
