In this guide we’ll take a look at the iOS 11.4 problems currently plaguing Apple’s mobile devices. We’ll also help those of you running into bugs and performance issues on iOS 11.4 and previous versions of iOS 11.
This walkthrough will show you where to find potential fixes for the most common iOS 11.4 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 what to know about the iOS 11.3.1 downgrade and a few things you can expect from Apple and its iOS updates going forward.
iOS 11.4 Problems
The iOS 11.4 update is 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.
iPhone and iPad users have run into various iOS 11.4 installation problems including errors in iTunes and frozen downloads. If your iOS 11.4 download gets stuck, hard reset your phone or tablet. This typically resolves the issue.
iOS 11.4 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.
A report from MacRumors reveals a microphone issue impacting select iPhone 7 and iPhone 7 Plus models running iOS 11.3.1 and iOS 11.3.
Some iPhone 7 users are seeing a grayed-out speaker button during phone calls and some claim they’re unable to be heard during regular phone calls and FaceTime video calls.
Apple is reportedly aware of the issue, but it’s unclear if the company will fix the issue with a software update. For now, iPhone 7 and iPhone 7 Plus users dealing with these issues are encouraged to get in contact with Apple customer service and escalate the issue to a senior AppleCare advisor.
I downloaded iOS 11.4 and still have the issue unfortunately :( Everytime I charge my phone to 100% battery the bug is triggered. I have to power my phone off and back on and it’s fine until I charge it again..

@AppleSupport the latest update iOS 11.4 has a major battery bug. Watched Battery percentage dropped 13% in literally less than 2 minutes.

@AppleSupport @beoplay Are you aware of an issue causing some (all?) Bluetooth headphones to produce very loud popping on R channel when playing audio on iOS (incl 11.4) recorded using stereo / binaural microphones?
Same audio with the same headphones play normally from Macs.

How to Fix iOS 11.4 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, iOS 11.3, iOS 11.3.1, or iOS 11.4 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 from iOS 11.4
If you run into trouble on iOS 11.4 you no longer have the option to downgrade to an older version of iOS 11.
Apple’s no longer signing on iOS 11.3.1 which means you can no longer use a loophole and downgrade from iOS 11.4 in an effort to improve your device’s performance.
Unfortunately the company’s also stopped signing on iOS 11.3, iOS 11.2.6, 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. Once you move to iOS 11.4, there’s no going back.
For more about how the downgrade process works, take a look at our detailed walkthrough.
Apple’s confirmed an iOS 11.4.1 update, but there’s a much larger update in testing right now.
The company’s released an iOS 12 beta for the iPhone, iPad, and iPod touch and the upgrade comes with a suite of new features and a focus on reliability and performance. This should be music to the ears of those who have struggled on iOS 11.
Beta software typically isn’t a viable alternative to official software, but those of you struggling on iOS 11.4 could try the iOS 12 beta and see if it helps. The final release won’t be out until the fall.
As for iOS 11.4.1, it’ll be out sometime before the final version of iOS 12 this fall. If you’re struggling on iOS 11.4, you’ll want to monitor the update as it passes through beta.
We expect it to stay in there for a few weeks while Apple and its army of beta testers poke and prod it for issues.
Install iOS 11.4 for Better Security
The iOS 11.4 update comes with 30+ patches aimed at improving your device's security making it an essential download for most iPhone and iPad users.
iOS 11.4 also reportedly comes with a USB Restricted Mode that disables the Lightning port on your iPhone or iPad if a device hasn't been unlocked or connected to a computer using a passcode within the last week.
If you missed any of Apple's previous iOS updates, your iOS 11.4 update could come with a lot more.
If you skipped iOS 11.3.1, your iOS 11.4 update comes with iOS 11.3.1's four security patches.
If you skipped iOS 11.3, your iOS 11.4 update comes with 27 additional patches for potential exploits. Those of you lingering on iOS 11.2.6 would be wise to make the move sooner rather than later.
If you missed iOS 11.3, your iOS 11.4 update 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 currently 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 11.4.
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.
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 11.4 right now.
If you skipped iOS 11.2, you'll get a few more patches with your iOS 11.4 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 11.4 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 11.4 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 11.4 update will come with even more 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 want to protect the data you store on your iPhone, iPad, or iPod touch, you should make your move to the latest version of iOS. This is particularly important for those of you running older versions of iOS.
