This iOS 8 thing is beginning to feel like the worst iOS upgrade ever. On my 5S, the screen sometimes gets stuck in a particular orientation. It will only let go if I quit the app or restart the phone. Also, when taking a picture, viewing it and then returning to the camera, the screen is often frozen. To unfreeze it, I have to preview the pic again. Most annoying bug so far is the wifi connection that just drops suddenly, with the phone switching back to LTE. Need to disable/enable wifi to restore functionality. Minor annoyance is the fact that background pictures seem to be weird in many apps, showing edges that were previously invisible. All in all, not a happy customer at the moment. Most 'advantages' of iOS8 have yet to materialize.
