Apple has released beta versions of iOS 16.4 to testers, so Apple will likely release that update to the public soon. But you should still download iOS 16.3.1 as soon as possible.
Apple released iOS 16.3.1 on Feb. 13, a few weeks after the release of iOS 16.3. Though iOS 16.3 included new features like security keys for Apple ID and support for the second-generation HomePod, the latest update fixes some issues that iPhone users might've run into recently, including a bug that Apple said might be actively exploited.
Here's what's included in Apple's iOS 16.3.1 update.
What's in iOS 16.3.1
The latest iOS update includes bug fixes and security updates that address issues with iCloud, Siri, Find My and crash detection.
Apple's security notes say this latest update patches an iPhone bug that may've been actively exploited. Apple writes that the bug may lead to arbitrary code execution, and the bug affects iPhone 8 models and later. According to Okta, arbitrary code execution could allow hackers to steal your data.
The update could also fix an iCloud issue some users ran into after the release of iOS 16.3. Some users on Reddit and Twitter have said they haven't been able to back up to iCloud since the release of the previous update.
Another issue that iOS 16.3.1 could address has to do with crash detection on iPhone 14 and 14 Pro models. Crash detection has helped alert first responders to some car crashes, but it has also been triggered when some users ride roller coasters with their phones.
Here's what Apple says is fixed with iOS 16.3.1.
- iCloud settings may be unresponsive or incorrectly display if apps are using iCloud.
- Siri requests for Find My may not work.
- Crash detection optimizations on iPhone 14 and iPhone 14 Pro models.
