5 Things to Know About the iOS 12.3.1 Update

    5 Things to Know About the iOS 12.3.1 Update is a post by Adam Mills from Gotta Be Mobile.

    Apple’s released a surprise iOS 12.3.1 update for iPhone, iPad, and iPod touch and the new version of iOS 12 brings bug fixes for a trio of issues.

    Without warning, Apple’s released a new version of iOS 12. iOS updates typically go through a beta testing period, but the fixes on board iOS 12.3.1 apparently couldn’t wait to wait for iOS 12.4.

    Unlike iOS 12.3, iOS 12.3.1 is a maintenance release which means it’s focused on fixing problems with the operating system. It doesn’t bring any new features to the iPhone, iPad, or iPod touch.

    If you’re currently running iOS 12.3, you just get the bug fixes with your upgrade. If you’re running an older version of iOS, your iOS 12.3.1 update is more substantial because you’ll get the features and fixes from any iOS updates you skipped.

    With that in mind, we want to take you through everything there is to know about Apple’s newest version of iOS 12.

    In this guide we’ll take you through iOS 12.3.1’s known changes, iOS 12.3.1 problems, places to look for feedback about the software, and our early impressions of its performance.

    iOS 12.3.1 Reviews

    The iOS 12.3.1 requires a small download.

    If you’re upgrading from iOS 12.3, your download should be right around 80MB. The iOS 12.3.1 update is a 77.9MB download for iPhone X owners and it’s similar download size for other iPhone models.

    If you’re running an older version of iOS 12, you’re going to see a larger download size because, again, the features and fixes from updates you skipped are baked into your update.

    If you’re currently running iOS 12.3, installing the iOS 12.3.1 update should take less than 10 minutes. It took about five minutes to install on an iPhone X.

    For more on the iOS 12.3.1 download and installation, take a look at our guide.

    We’ve been using the iOS 12.3.1 update on our iPhones and iPads for a short time and here’s what we’ve found thus far:


    • Battery life is stable right now.
    • Wi-Fi connectivity is stable and fast.
    • Bluetooth is working normally.
    • GPS and cellular data are currently stable.


    • Third-party apps including Netflix, Dark Sky, Twitter, Slack, Asana, Gmail, Chrome, and Spotify are all working normally.
    • First party apps like Safari, Podcasts, and Calendar are working fine.


    • iOS 12.3.1 feels as fast as iOS 12.3. iOS 12.3 was fast on all of our iPhones.

    If you’re dealing with bugs or performance issues on iOS 12.3 or another version of iOS 12, you’ll probably want to install iOS 12.3.1 right away.

    If you need help making a decision, check out our reasons to, and not to, install the iOS 12.3.1 update on your iPhone, iPad, or iPod touch right now.

    We’re in the process of publishing our iOS 12.3.1 reviews for the iPhone X, iPhone 8, iPhone 7, iPhone 6s, iPhone 6, iPhone 5s, and iPhone SE so check those for additional feedback if you need it.

    If you’re having a great experience on iOS 12.3 or an older version of iOS, make sure you dig into additional feedback before jumping up to iOS 12.3.1.

    iOS 12.3.1 Problems

    iOS 12.3.1 users are encountering a variety of bugs and performance issues in the early going.

    The early list of iOS 12.3.1 problems includes download and installation issues, connectivity issues, data issues, issues with Exchange, abnormal battery drain, random reboots, crashes, UI lag, and issues with first and third-party apps.

    If you run into an issue while running iOS 12.3.1 have a look at our list of fixes for the most common iOS 12 problems. We’ve also released some tips to improve iOS 12 performance and tips to improve iOS 12 battery life.

    If you can’t stand iOS 12.3.1’s performance on your phone or tablet, you can try downgrading to the previous version of iOS 12. It might help.

    Apple is signing on iOS 12.3 which means you use a loophole to downgrade to the previous version. If iOS 12.3 was running well on your device, this is a solid option.

    You can’t downgrade to anything older than iOS 12.3. Apple recently closed up the iOS 12.2 downgrade path.

    iOS 12.3.1 Update: What’s New

    The iOS 12.3.1 update is a small release and it carries a few fixes for issues with the Messages app and VoLTE calls. Here’s the full change log:

    • Fixes an issue that could prevent making or receiving VoLTE calls.
    • Fixes issues in Messages that could cause messages from unknown senders to appear in your conversation list even though Filter Unknown Senders is enabled.
    • Fixes an issue that could prevent the Report Junk link from appearing in Messages threads from unknown senders.

    iOS 12.3.1 doesn’t carry any new security patches for the iPhone, iPad, or iPod touch.

    iOS 12.3.1 Jailbreak

    You can’t jailbreak iOS 12.3.1 right now.

    If you want to jailbreak your device you can jailbreak using the Chimera tool, but only if you’re running iOS 12.0-iOS 12.1.2. It’s a semi-tethered jailbreak and it supports newer models like the iPhone XS.

    You can also use the unc0ver jailbreak tool. Unfortunately, devices that use the A12 processor (like iPhone XR, iPhone XS and iPhone XS Max) aren’t supported.

    Unfortunately, there’s no way to downgrade to any of these versions of iOS 12. So if you’re running iOS 12.3.1, iOS 12.3, iOS 12.2, iOS 12.1.4, or iOS 12.1.3 you’ll have to wait for developers to release a new tool.

    What’s Next

    Unless Apple releases a surprise iOS 12.3.2 update, the next version of iOS 12 will likely be iOS 12.4.

    Apple’s confirmed iOS 12.4 and the update is in beta testing ahead of a release later this year. We expect the software to launch sometime this summer alongside the Apple Card credit card.

    Like iOS 12.3, iOS 12.4 is a milestone update which means it will carry a mix of bug fixes, security patches, enhancements, and features.

    If you’re struggling on iOS 12.3.1 or simply want to give iOS 12.4 a try before its official release date, you can do so via the iOS 12.4 beta.

    Before iOS 12.4 arrives, we’ll probably get the first version of iOS 13.

    WWDC 2019 kicks off on June 3rd and it’s there that we’ll likely learn about Apple’s upcoming iOS 13 operating system. We’ve heard quite a bit about it already and the company should fill in some more blanks during its keynote.

    Shortly after the conclusion of the keynote, we expect Apple to release the first iOS 13 beta for iPhone, iPad, and iPod touch giving users a chance to test the software long before its release this fall alongside the 2019 iPhones.
