Is your iOS device rebooting endlessly? This is a well-known bug and it has already been fixed by Apple but if you haven't updated your iOS device you might still have this issue. What causes the iPhone or iPad to reboot in a loop? A glitch in the notifications system is crashing springboard, the part of iOS that handles your home screen. Apps with daily notifications (workout apps, medication reminder apps, etc), in particular, seem to be triggering the crash but only after your device’s clock passes 12:15 AM on December 2nd, 2017. That it originates from apps with daily notifications means it’s not affecting everyone — but it also makes it pretty hard to narrow down the list of impacted apps. There are just too many. How to fix it? If you can get your device to boot for a few minutes without crashing and you can remember which apps send daily notifications, turn off notifications for those apps by going to Settings > Notifications > the app in question > toggle “Allow notifications”. As a last resort, you can go through and manually turn off notifications for each and every third-party app and work backward in turning them back on. Once you’ve got your device to stop resetting, update iOS. Apple has officially released iOS 11.2, and it appears to fix this issue — but you’ll still need to get your device stable enough to update, first. Once you’re on 11.2, you can turn all those notifications back on.
