A few nights ago I discovered that at less than 12 º C the flash did not work (even forced in "yes" position). Once I got home, it worked again. I asked for an appointment at Apple Barcelona and they told me it was the first case they heard. They changed the terminal to me but it continues acting the same. I already know several cases in different world forums. Does anyone know more cases? I invite you to take the test please and comment here. If it is confirmed, it will be necessary to get Apple to solve this problem. Thank you
