Hello there, I got 3 x iPhone 6 with same issue of crashing iOS this morning. It just goes to black screen with loading sign and comes back to ask Passcode. It is not App just happens without even opening any App. It is not battery or any other hardware as I did check. As per clients it happened over night in Auckland NewZealand. It is quite strange issue because it didn’t happen straight after update. Any one has any idea? What it could be and possible solution?
Hello Ben, The manual time thing didn’t fix the issue but I found a solution, actually, it is due to notifications, So I just turned off notifications. Settings > Notifications > Show Previews > Never Source: https://www.theverge.com/2017/12/2/16727… Phones are working normally. It worked for me… Thanks Regards Danesh
The recent iOS update has a bug where if the system date and time is not set correctly the phone would keep rebooting every 5 minutes. Chances are apple will release a hotfix update for this in a few days. The solution to this for the time being is to manually set the date and time and leave it manually set.
