What is the white flash or shadow appearing on the screen when opening various apps?
My iPhone 5 iOS 7.1.1 shows a large white spot flashing on the upper left side when opening various apps. It's not consistent to a certain app, but happens frequently. I have (not too) many apps and I suspect one of them is the polluting culprit. It's like a damage or disturbance to the animation effect. One has to be really quick to take a screen shot, still I have seen one on a different Apple community discussion but I'm not able to retrieve it now.
