Apple is busy beta testing its big iOS 14.3 update, but today is also released a new, smaller update to the public.

iOS 14.2.1 is now available for download. This is update is focused on fixing bugs, including an issue where some MMS messages may not be received and a bug that could cause the iPhone 12 mini's lock screen to become unresponsive.

Here's Apple's full changelog for the iOS 14.2.1 update:

iOS 14.2.1 addresses the following issues for your iPhone:

• Some MMS messages may not be received
• Made for iPhone hearing devices could have sound quality issues when listening to audio from iPhone
• Lock Screen could become unresponsive on iPhone 12 mini

Small bug-fixing updates like this may not be super exciting, especially compared to big updates like iOS 14.2 that bring a ton of new features. Releases like iOS 14.2.1 help to ensure that your phone is working smoothly, though, and that's important especially as many people rely on their smartphone as their main computer.

To get this iOS 14.2.1 update, launch the Settings app on your device and tap on "General" followed by "Software Update".
