If your iPhone started c.rashing at midnight on Dec. 2, iOS 11.2 will fix it.
It’s like Y2K all over again for iPhone users. When the clock struck midnight on December 2, 2017, many iPhones that were running iOS 11.1.2 began inexplicably rebooting and crashing. But if you’re one of the affected users, there’s already a fix.
The bug involves iOS’s “local” notifications, alerts that happen on your iPhone rather than Apple’s push notification service. It’s difficult to know which apps use local notifications and which use remote notifications, but one example is meditation app Headspace, which sends users daily reminders to relax and breathe. Any app that sends local notifications could be a culprit.
Users on Twitter are complaining about their phones randomly restarting.
As a result, Apple pushed out iOS 11.2 in the middle of the night, a major update that also brings Apple Pay Cash, faster wireless charging for the iPhone 8 and X, and a number of bug fixes and visual changes. The sixth beta of iOS 11.2 was released yesterday, just days after beta 5 landed. It was presumably released early as a result of the bug, as Apple doesn’t usually push out major iOS updates after midnight on a Saturday.
