iOS 11.0.3 Problems: 5 Things You Need to Know

Apple’s new iOS 11.0.3 update comes with fixes for lingering issues, but it’s also brought some frustrating problems to iPhone, iPad, and iPod touch users.

Apple’s new version of iOS 11 brings fixes for iPhone 7 sound problems, but some iPhone and iPad users are already reporting installation problems, abnormal battery drain, Wi-Fi problems including a serious issue called KRACK (Key Reinstallation Attack), lag, and issues with Bluetooth.

The update is only a few hours old so we expect the list of iOS 11.0.3 problems to grow as more iOS 10 users upgrade to iOS 11 and as more iOS 11 users move to the new version.

Today we want to take a quick look at the iOS 11.0.3 problems plaguing Apple’s devices and help those of you running into trouble.

This guide will show you where to find potential fixes for the most common iOS 11 issues and provides some resources that could come in handy if your version of iOS 11 starts acting up.

Our walkthrough also takes you through the downgrade and a few things we expect from Apple going forward.

iOS 11.0.3 Problems

The iOS 11.0.3 update is very new, but we’re already starting to see complaints from iPhone and iPad users. Some of these iOS 11.0.3 problems are new, but many of them have carried over from the first three versions of iOS 11.

iPhone and iPad users are running into various installation problems including errors in iTunes and abnormally long download times.

One of our devices was unable to find the iOS 11 update in settings and we continually got an “Unable to Check for Update” error. The issue went away after several attempts to download the software.

iOS 11 users are reporting heavy battery drain, lag, random reboots, Touch ID problems, touchscreen issues, problems with sound, issues with Siri, and problems with first and third-party apps including GarageBand.

The company’s also confirmed a serious Wi-Fi vulnerability called KRACK. KRACK stands for Key Reinstallation Attack and it’s an exploit that targets the common WPA2 encryption protocol. A fix for this issue will be made available in the company’s upcoming iOS 11.1 update.

Apple’s official discussion forums, Reddit, and social media sites like Twitter are filling up with complaints about iOS 11 and we expect to see new problems emerge in the weeks ahead.

You can’t predict what kind of performance you’ll see on your phone or tablet and that’s why we recommend doing some prep work before you install iOS 11.0.3 on your iPhone, iPad or iPod touch.

We’ve put together a step-by-step process and our checklist will take you through the iOS 11.0.3 pre-installation process. A little prep work can go a long way toward preventing issues.

Where to Find Feedback

As we push away from the iOS 11.0.3 release date it’s important to keep your eyes on feedback coming from your fellow iPhone, iPad, and iPod touch owners.

Digging into ongoing iOS 11 feedback will alert you to potential benefits (if you haven’t installed iOS 11 yet) and potential problems. Again, the problems discovered today are just the tip of the iceberg.

We’ve put together some reasons to and not to install the iOS 11.0.3/iOS 11 update to help get you started. If you’re on the fence about making the move to iOS 11 and iOS 11.0.3, start there.

We also recommend keeping an eye on YouTube, Apple’s discussion forums, social media sites like Twitter/Facebook, and the MacRumors forums for additional feedback about the current version of iOS 11.

We’ve also put together some first impressions of iOS 11.0.3 on the iPhone. We plan to cover more iOS 11.0.3 updates in the near future so keep an eye out for our quick reviews.

How to Fix iOS 11 Problems

If you start running into trouble on iOS 11.0, iOS 11.0.1, iOS 11.0.2, or iOS 11.0.3 there’s no need to panic. Most iOS issues can be fixed in a matter of minutes from the comfort of a computer chair or couch.

Before you take your phone or tablet down to an Apple Genius you should try fixing the problem on your own.

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 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 Downgrade

You can also try downgrading back to a previous version of iOS 11 if you think that might help.

Apple is signing off on iOS 11.0.1 and iOS 11.0.2 which means you can drop back down to an older version of iOS 11 in an effort to improve your device’s performance.

Apple will only sign off on iOS 11.0.1 and iOS 11.0.2 for a short time which means you’ll need to move quickly. It won’t announce anything ahead of time.

The company is no longer signing on iOS 11.0 or iOS 10.3.3 which mean there’s no going back to iOS 10. Once you move to iOS 11, you’re stuck.

If you’re curious about the downgrade process and how it works, take a look at our detailed walkthrough.

What’s Next

Apple hasn’t confirmed an iOS 11.0.4 update so it could be a few days before we see the next bug fix update. That said, the company’s confirmed a major iOS 11 release in the form of iOS 11.1.

iOS 11.1 is currently in beta ahead of a public release. The first beta is light on features, but it does come with a few fixes for ongoing iOS 11 problems. Milestone upgrades typically come with a solid list of bug fixes so don’t be surprised if Apple loads iOS 11.1 up.

Apple hasn’t confirmed an iOS 11.1 release date, but our best guess at this point is an arrival in late October or early November alongside the iPhone X.

Keep an eye out for new details, including new iOS 11.1 betas, as we cruise through October.

4 Reasons Not to Install iOS 11.0.3 & 9 Reasons You Should

Install iOS 11 for Better Security

Install iOS 11 for Better Security

If the security of your device is important to you you'll probably want to install iOS 11.0.3 today or sometime in the near future. 

The iOS 11.0.3 update doesn't come with any new security patches. It simply features the patches from the iOS 11.0 update. (Note: iOS 11.0.1/iOS 11.0.2 didn't come with any new patches either.)

Apple's initial iOS 11.0 update delivered several patches for potential exploits. These patches address serious vulnerabilities in iOS. If you're coming from iOS 10, the iOS 11.0.3 update delivers eight patches to the iPhone, iPad, and iPod touch. 

That's not all. iOS 11 also comes with new security features aimed at keeping your data safe. Elcomsoft recently discovered a change to the way iOS deals with trusted devices. 

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 previous versions of iOS, your iOS 11.0.3 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 in iOS 11.0.3. And if for some reason you missed iOS 10.3, you'll get 60 security patches with your version of iOS 11.0.3. 

If you want to protect the data you store on your iPhone, iPad, or iPod touch, you should make your move to iOS 11/iOS 11.0.3 soon. This is particularly important for those of you running older versions of iOS.

    Since upgrade 11.0.2 I keep getting and error that says iTunes Store error and when I try to go into iTunes all I get is cannot connect! I’ve tried several recommendation but nothing helps. Is there anyone out there that can help and why has Apple not fixed this if they know about it. So frustrating!

    Since I’ve installed the iOS 11.0.2 on Wednesday, 10/4/17 I’ve had problems with my, iPad mini, my iPhone s.e and my Mac Pro. I can’t send to receive emails, messages or sign into iCloud. I have been in communications with 3 different people trying to help me. They wrote a ticket to the engineering department. I’ve never ever been so frustrated with apple as I am now.

    I can’t believe that apple would roll out a new software with so many bugs and problems. The real explanation for the long waiting time. I’m afraid that while everything is glitchy and down that my devices may be vulnerable to hackers.

    Don’t down load the iOS 11.0.2 !!!!!

    iOS 11.x (in my case 11.0.2) also broke USB connectivity for hands free and music for 2011/2012 (possibly other years with the same receiver) Hyundai cars/trucks.

    As I have an iPhone 6s, I was able to roll back to 10.3.3, then update to 11.0.1 to repair the issue (but had to upgrade to beta 11.1 first to facilitate the rollback).

    That door will now be closed as 11.0.3 fixes the screen issue with the 6s that Apple left the downgrade to 10.3.3 open for.

    People should also be aware, once you downgrade iCloud backups are no longer possible with your device. Apple also hides any iCloud backups for older iOS revisions. They don’t support rolling back.


  24. […] iPad iOS 11.0.2 update is also causing a variety of problems for iPad users. iPad users are complaining about poor performance, connectivity issues, problems apps and […]


  25. […] The most recent iOS 11.1 beta brought a fix for an annoying Reachability bug and the update will also patch up a nasty Wi-Fi exploit. […]
