Vibrate on silent: iPhone only vibrates when it is not muted. Display Rotation: Display does not rotate when iPhone is held portrait or landscape. Which causes that all the pictures taken and all incoming text messages are tagged with the same time are again sorted wrong. it stays at the last time when it is manually set. Date and time progression: This is the most interesting! iPhone clock for indicating the time does not change. Location Services: iPhone cannot locate itself. But as I said, there is more: After I realized that WiFi switch grayed out, I also realized that following functions started not to work either.

For sure Ive tried hardware restart (almighty 10 secs of two-button press), syncing with iTunes and updating firmware but the most annoying is to be limited with cellular data. I have the same problem with my iPhone 6 and more to that.
