5 Things to Know About the iOS 12.1.2 Update



Apple’s released a new version of iOS 12 and the iOS 12.1.2 update is currently available for all iPhone, iPod, and iPod touch models capable of running iOS 12.

In late 2018, Apple put the iOS 12.1.2 update into beta with new bug fixes. The release came just a few days after the company released its iOS 12.1.1 update.

In a bit of a surprise, the company’ quickly pulled the iOS 12.1.2 update out of beta and released it for all iOS 12 users bringing additional bug fixes and changes to the mobile platform.

The iOS 12.1.2 is another point upgrade, but it contains important bug fixes for lingering iOS 12 problems on the iPhone XR, iPhone XS, and iPhone XS Max.

In this guide to the iOS 12.1.2 update we’ll take you through the most important things to know about the new firmware. Our walkthrough includes a quick look at iOS 12.1.2’s performance and download size, iOS 12.1.2 problems, the iOS 12 downgrade, and what’s next from Apple.

iOS 12.1.2 Reviews

iOS 12.1.1 was a point upgrade but it required a significant chunk of space to download. iOS 12.1.2 is a much smaller release for the iPhone, iPad, and iPod touch.

If you’re moving your phone from iOS 12.1.1, your download is tiny. The iPhone X’s iOS 12.1.2 update is just 83.5MB. You should be able to download it in seconds.

If you’re running an older version of iOS 12 or if your device is still running iOS 11, you’re going to see a much bigger download size because you’ll get the features and fixes from the updates you skipped inside your version of iOS 12.1.2.

As for the iOS 12.1.2 installation, it shouldn’t take more than 5-10 minutes to complete if you’re coming from iOS 12.1.1. It took just five minutes to install on the iPhone X and about five minutes on the iPhone 5s as well.

For more on the iOS 12.1.2 download and installation, take a look at our guide.

We’ve been using the iOS 12.1.2 update on a handful of devices for an extended period of time (we also used the iOS 12.1.2 beta) and here are our quick impressions of its performance:


  • Battery life is stable on our phones and tablets.
  • Wi-Fi is stable and fast.
  • No Bluetooth issues thus far.
  • GPS and cellular data are functioning normally.


  • Third-party apps including Twitter, Slack, Asana, Gmail, Chrome, and Spotify are working fine.
  • First party apps like Safari, Podcasts, and Calendar are stable.
  • Netflix has crashed once already.


  • iOS 12.1.2 is as fast as iOS 12.1.1.

If you’ve been dealing with bugs and performance issues you should think about installing iOS 12.1.2 in the near future. If you’re having a great experience on iOS 12.1.1 or an older version of iOS, you might want to wait for more long-term feedback to emerge.

iOS 12.1.2 Update: What’s New

iOS 12.1.2 is a maintenance update which means it comes with bug fixes and under-the-hood improvements. It doesn’t have any security patches on board.

Apple’s official change log notes two bug fixes:

  • Fixes bugs with eSIM activation for iPhone XR, iPhone XS, and iPhone XS Max,
  • Addresses an issue that could affect cellular connectivity in Turkey for iPhone XR, iPhone XS, and iPhone XS Max.

There’s also a new animation for force closing apps in China which you can see in the video below. Apple did this to address Qualcomm patents.

Developers digging through the beta discovered a few other changes. These included:

  • Audio performance when using some third-party apps is improved on iPad Pro 12.9-inch (3rd generation) and iPad Pro 11-inch.
  • An issue with the brightness jumping up and down around 15% on XS Max (maybe on XS too) when True Tone or Night Shift are enabled.
  • An issue where the lock screen keyboard would still register clicks and prevent clicking on home screen icons if it’s not displayed on the home screen right after.

Apple’s released a new version of iOS 12.1.2 for the iPhone with build number 16C104″ (the original iOS 12.1.2 update is called “16C101”) though it’s unclear what the new build has on board. We assume there are bug fixes but Apple hasn’t released an updated change log.

Those who haven’t updated to iOS 12.1.2 yet will likely see the new build. Those who’ve already moved to iOS 12.1.2 won’t see a prompt.

iOS 12.1.2 Jailbreak

Jailbreak developers haven’t released an iOS 12 jailbreak and it’s unclear if we’ll get one in 2019.

The only way you can jailbreak a device right now is if it’s running an older version of iOS 11. Unfortunately, there’s no way to downgrade to iOS 11.

What’s Next

Apple’s confirmed an iOS 12.1.3 update and the software is in beta ahead of an unknown release date.

The company is currently on iOS 12.1.3 beta 2 which means an official release is likely coming sometime in early 2019.

If you’re struggling on iOS 12.1.2 or just want to give the new software a try before it’s officially released to the public, you can do so via the iOS 12.1.3 beta.

The iOS 12.1.3 beta is available for all devices capable of running iOS 12.
