Apple’s iOS 11.3 update fixes a ton of lingering iOS 11 issues, but its also brought its own collection of problems to iPhone, iPad, and iPod touch.
While some iPhone and iPad users have seen a performance boost, other iOS 11.3 users are running into installation problems, abnormal battery drain, Wi-Fi problems, lag, and issues with Bluetooth.
In this guide we’ll take a look at the iOS 11.3 problems currently plaguing Apple’s mobile devices. We also want to help those of you running into bugs and performance issues on iOS 11.3 and older versions of iOS 11.
This walkthrough will show you where to find potential fixes for the most common iOS 11 issues. It also lists off some resources that could come in handy if your version of iOS 11 starts acting up.
Our walkthrough also takes you through how to downgrade from iOS 11.3 and a few things you can expect from Apple and its iOS updates going forward.
iOS 11.3 Problems
The iOS 11.3 update is already causing problems for some iPhone, iPad, and iPod touch users. Some of these problems are brand new, others have carried over from the previous versions of iOS 11.
iOS users have run into various iOS 11.3 installation problems including errors in iTunes and locked up downloads. If your iOS 11.3 download gets stuck, hard reset your phone or tablet. This typically resolves the issue.
iOS 11.3 users are also reporting heavy battery drain, AirPlay issues, Touch ID problems, abnormal amounts of lag, problems with sound, missing battery indicators, and problems with various first and third-party apps. We’re also hearing about issues with the iPhone X’s Face ID.
According to VICE, the iOS 11.3 update’s also killed touch functionality on iPhone 8 models repaired with aftermarket displays. A new report from iFixit claims the issue isn’t malicious and that it’s simply a bug that Apple needs to work out.
It’s unclear when or even if Apple will release a software fix for the issues.
@AppleSupport Evening! My iPhone X has stopped auto filling information on sites I use – normally picks up my Face ID and good to go, now it’s not. It’s since updating to iOS 11.3

How to Fix iOS 11.3 Problems
If you start running into trouble on iOS 11.0, iOS 11.0.1, iOS 11.0.2, iOS 11.0.3, iOS 11.1, iOS 11.1.1, iOS 11.1.2, iOS 11.2, iOS 11.2.1, iOS 11.2.2, iOS 11.2.5, iOS 11.2.6 or iOS 11.3, there’s no need to panic. You can manually fix most issues from the comfort of a computer chair or couch.
We’ve put together a list of fixes for the most common iOS 11 problems. The list is a great starting point for those of you dealing with iOS 11 issues.
We’ve also released a list of tips that could help you improve your device’s performance and some ways to fix iOS 11 battery life problems.
If you’re unable to find a fix for your issue in those guides, you should go to Apple’s discussion forums for help. If Apple’s forums aren’t helpful, you can get in contact with Apple Support via Twitter or via the company’s website.
If Apple’s online support can’t help, you should schedule an appointment to see a Genius at your local Apple Store. They should be able to diagnose your issue and provide you with a fix or a replacement depending on your warranty.
You Can’t Downgrade to iOS 11.2.6
If you run into trouble while on iOS 11.3 you’re on your own until Apple releases a brand new version of iOS 11.
Apple’s no longer signing off on iOS 11.2.6 which means you can no longer drop back down to the older version in an effort to improve your device’s performance.
Unfortunately, the company’s also stopped signing on iOS 11.2.5, iOS 11.2.2, iOS 11.2, iOS 11.1.2, iOS 11.1.1, iOS 11.1, iOS 11.0.3, iOS 11.0.2, iOS 11.0.1, iOS 11.0, and iOS 10.3.3.
If you’re curious about how the downgrade process works for next time, take a look at our detailed walkthrough.
Given the amount of bugs on board iOS 11.3, there’s a chance Apple releases an iOS 11.3.1 update in the near future. The company hasn’t confirmed, but those struggling on the software should keep an eye out in the days ahead,
If you’re dealing with iOS 11.3 problems relief will definitely come in a few weeks. Apple says it plans to push out a new iOS 11.4 update ahead of iOS 12.
iOS 11.4 is a milestone upgrade and Apple’s iOS milestone upgrades typically come with a long list of features, enhancements, bug fixes, and patches.
The iOS 11.4 update is currently available via a beta. If you’re really struggling on iOS 11.3 downloading the iOS 11.4 beta is an option. That said, this is an early version of iOS 11.4 and pre-release software is often extremely buggy. iOS 11.4 beta testers are complaining about several bugs and performance issues.
Apple is also reportedly working on an iOS 12 update for the iPhone, iPad, and iPod touch and sources claim the company is planning to delay some features in order to focus on reliability and performance.
While some iOS 12 features will likely be pushed into 2019, Apple’s next operating system should make its debut this summer at the company’s annual WWDC conference in California.
Install iOS 11.3 for Better Security
iOS 11.3 also includes a new privacy feature. When an Apple feature wants to use your personal information, an icon now appears with a link to access detailed information about how your data will be used and protected.
If you're running iOS 11.2.5 or older, you're exposed to an issue that lets people send a specific character that will crash an iOS-powered device and block access to the Messages app. It can also block apps like Facebook Messenger, Gmail, Outlook, and WhatsApp.
The iOS 11.2.6 update's main purpose was to patch up this issue. If you skipped iOS 11.2.6, you'll get these enhancements with iOS 11.3.
If you're running iOS 11.2.2 or below and receive a certain GitHub link through your Messages app, your iPhone or iPad can lockup or respring. The Messages app will also become unusable.
If you're on iOS 11.2.1, your iOS 11.3 update includes security improvements to Safari and WebKit to mitigate the effects of Spectre. If you're running an older version of iOS, your iOS 11.3 update will come with a lot more.
Apple's iOS 11.2 update fixed several problems, but it also brought problems of its own including a potentially nasty zero-day iOS HomeKit vulnerability.
The vulnerability, discovered by Tian Zhang, allowed for unauthorized control of HomeKit accessories including garage door openers and smart locks.
Apple quickly rolled out a server-side fix, but the company restored full functionality with the release of iOS 11.2.1. If you skipped iOS 11.2.1 and use HomeKit, you should download iOS 11.3.
If you skipped iOS 11.2, you'll get a few more patches with your iOS 11.3 update. Apple's iOS 11.2 update delivered 11 patches including one for Mail and one for Wi-Fi.
The iOS 11.2 and iOS 11.2.1 updates also patched up a widespread security issue called "Meltdown." Apple says its analysis suggests it "has the most potential to be exploited."
Meltdown affects all iOS 11 powered devices so we highly recommend downloading iOS 11.3 if you skipped iOS 11.2.
If you skipped iOS 11.1.2, iOS 11.1.1, and iOS 11.1, you'll get additional patches with your iOS 11.3 update.
The iOS 11.1 update delivered eight security patches including a fix for a serious Wi-Fi vulnerability called KRACK or Key Reinstallation Attack. KRACK is an exploit that targets the common WPA2 encryption protocol.
If you're just now making to move from iOS 10 (or whatever you're on) to iOS 11, your iOS 11.3 update will come with additional security features.
In iOS 11 you can't establish trust with a PC using fingerprints alone. You'll also need to put in a full passcode in order to gain that trust.
If you skipped older versions of iOS, your iOS 11.3 update will come with an even longer list of security patches.
Apple's iOS 10.3.3 update delivered 24 security patches addressing potential issues with Contacts, Messages, Notifications, and Safari. It also included a patch for a potentially dangerous Wi-Fi exploit called "Broadpwn."
If you skipped iOS 10.3.2 you'll get 23 additional patches with iOS 11.3. And if for some reason you missed iOS 10.3, you'll get 60 security patches with your iOS 11.3 update.
If you want to protect the data you store on your iPhone, iPad, or iPod touch, you should make your move to iOS 11 and iOS 11.3 soon.
This is particularly important for those of you running older versions of iOS.
