There’s a bug in iOS versions prior to 11.2 that causes apps with local notifications to crash your iPhone or iPad once your date is set to December 2nd (or later). Apple has fixed this with iOS 11.2, released yesterday. Normally waiting a day or three to update to a new iOS release can be prudent, but not in this case. If your iPhone isn’t crashing yet, update to iOS 11.2 now to avoid this 12/2 notification bug altogether.
If your iPhone is crashing due to this bug, Apple has published steps to allow you to update and fix it:
If your device with iOS 11 unexpectedly restarts repeatedly on or after December 2, 2017, learn what to do.
Use these steps to turn off notifications for all the apps on your device, then update your device to iOS 11.2:
- Tap Settings > Notifications.
- Tap an app, then turn off Allow Notifications. Repeat this step for each app.
- Update your device to iOS 11.2.
- After updating, tap Settings > Notifications and turn Allow Notifications on again for each app.
For steps 1 and 2 you really only need to disable notifications for apps that deliver local notifications – since that’s the only thing this December 2 notification bug affects – though sometimes that’s not necessarily obvious.
Apps that set local alarms (sleep trackers, White Noise apps) are one general type. The Deliveries app is another one that doesn’t receive push notifications and instead delivers them locally from itself.
Depending upon how many apps you have on your iPhone it might be worthwhile to just disable those and see if it helps. If you find a specific app that does local vs. push notifications, leave it in the comments below to make life easier for the next person who comes along. We’ll get through this one together, folks!
