Might I ask if you were doing anything specifically when it started happening? For example, a lot of the photos of this problem that have been posted on this thread show that the users’ iPhones were having some other kind of problem at the same time, such as a bunch of notifications stating that text messages failed to send. Additionally, several people were live chatting with Apple when it happened. So have you been having any other issues that might explain why this issue is coming up? Additionally, I would be interested to know whether these incidents are more common in certain countries or regions (e.g. Middle East), not sure how to determine that though.
