Yesterday, Apple released iOS 14.2.1 to fix bugs users have encountered on new iPhones since the launch of iOS 14.2 on November 5. Unlike many other iOS releases, this release was not accompanied by updates to all of the company’s other operating systems.
The update addresses a bug that caused an unresponsive lock screen on the iPhone 12 mini specifically, and resolved an issue that prevented MMS messages from arriving. Additionally, 14.2.1 resolves an issue with sound quality on connected hearing aids.
Here are Apple’s release notes for iOS 14.2.1:
iOS 14.2.1 fixes the following issues for your iPhone:
- Some picture messages may not be received
- Made for iPhone hearing aids may have sound quality issues when listening to audio from the iPhone
- Lock screen may become unresponsive on iPhone 12 mini
The previous update, iOS 14.2, was a bit bigger. Among other things, it added over 100 new emoji, included Shazam in the control center, and introduced new audio and AirPlay features. That update was accompanied by updates to watchOS, tvOS, and others.
Typically, updates with two decimal places are minor bug fix updates, updates with only one decimal place are minor feature updates, and updates with only an integer (such as iOS 14) are annual major releases.
iOS 14.2.1 should now be available to all users on supported devices (anyone named iPhone 12).
