Apple’s replaced its iOS 11.0.1 update with a new iOS 11.0.2 update and the new firmware delivers key bug fixes for the iPhone 8 and iPhone 8 Plus.
Apple usually puts its iOS updates through beta testing, but the company’s rushed out the last two updates in order to fix iOS 11 problems on the iPhone, iPad, and iPod touch.
The iOS 11.0.1 update fixed serious issues with Exchange and Outlook and the iOS 11.0.2 update is focused on fixing annoying iPhone 8 problems and a few lingering iOS 11 issues.
iOS 11.0.2 is a maintenance update, but it’s still a fairly big download. The iOS 11.0.2 update is another 278MB for the iPhone 7. The iOS 11.0.1 was a similar size.
If you’re coming to iOS 11.0.2 from an older version of iOS, your download will be larger (in some cases, substantially larger) because the features from the updates you skipped are baked in.
Apple’s latest iOS 11 update fixes problems on the iPhone and iPad, but we’re already hearing about iOS 11.0.2 problems plaguing iPhone, iPad, and iPod touch users. Some iOS 11.0.2 users are dealing with installation problems, others are noticing performance issues like abnormal battery drain.
Our iOS 11.0.2 update guide goes over the most important things to know, right now, about the new iOS 11 update for iPhone, iPad, and iPod touch.
It includes our impressions of the iOS 11.0.2 update on the iPhone and iPad, a quick look at iOS 11.0.2 problems, the iOS 10 downgrade, and what to expect next from Apple.
iOS 11.0.2 Review
Apple’s maintenance releases sometimes are just a few megabytes, but the iOS 11.0.2 update is much larger than your standard bug fixer.
Again, the iPhone 7 iOS 11.0.2 update is a pretty big download, 278MB if you’re coming from iOS 11.0.1, though it should only take you a minute or two to download over a fast Wi-Fi network.
The installation process will take you a little bit longer. iOS 11.0.2 took about five minutes to install on our iPhone 7 and you can expect the same if you’re currently running iOS 11.0.1.
We’ve only been using the iOS 11.0.2 update for a week now, and the update is, for the most part, holding up fine on the iPhone 7, iPhone 5s, and other iOS 11-powered devices.
We haven’t experienced any weird battery life drain. We didn’t see any on iOS 11.0.1 either. We’ve also managed to connect to Wi-Fi and Bluetooth devices. Cellular data also appears to be normal. We’re running the iPhone 7 on AT&T’s network.
As of right now, our core apps are stable. We haven’t experienced issues with Asana, Slack, Twitter, Spotify, Podcasts, YouTube, Gmail, or the Mail app. That could change down the road.
The iPhone 7 is also fast with iOS 11.0.2 on board. We haven’t noticed any user interface lag, freezes or lockups. Random reboots were an issue for us on iOS 10, but we haven’t noticed any yet.
That said, you’ll want to be careful with iOS 11.0.2. New software, even small updates like iOS 11.0.2, can cause problems. Older devices like the iPhone 5s are particularly susceptible to performance problems.
If you need additional feedback about iOS 11.0.2 and iOS 11, take a look at our reasons to, and not to, install the iOS 11.0.2 update on your device right now.
We’ve also put together guides to the iPhone 7 (a little more extensive than our impressions here), iPhone 6s iPhone 6, iPhone 5s, iPhone SE, and iPad iOS 11.0.2 updates with more impressions coming soon.
iOS 11.0.2: What’s New
The iOS 11.0.2 doesn’t bring a long list of bug fixes or security updates with it. Instead, it’s focused on patching up iOS 11 and iOS 11.0.1 problems.
The iOS 11.0.2 change log notes that it comes with a fix for a crackling sound issue on the iPhone 8 and iPhone 8 Plus, a fix for a bug that could cause photos to become hidden, and a fix for an issue where attachments in S/MIME encrypted emails would not open.
If you’re moving from iOS 11.0.1, that’s all you’ll get. iOS 11.0.2 doesn’t come with any additional security patches. Apple says that iOS 11.0.2 includes the security content from iOS 11.0.
iOS 11.0.2 Problems
While some iOS 11.0.2 users are having a good experience, others are running into trouble. Some of these issues are new, others carried over from the previous versions of iOS 11.
iPhone and iPad users are noticing installation problems (the update’s getting stuck during the download/installation process), various connectivity problems, abnormal battery drain, issues with first and third-party applications, Bluetooth issues, and UI lag.
Apple’s also acknowledged an iOS 11 Reachability bug and it says it’s working on a fix in an upcoming version of iOS 11.
If you’re already noticing bugs or problems, take a look at our list of fixes for the most common iOS 11 problems. Our list should have you covered.
iOS 10 Downgrade Closed
If you can’t stand iOS 11.0.2’s performance on your device you can always downgrade.
If you’re looking to move off iOS 11.0.2, you can drop back down to iOS 11.0.1 in an effort to improve performance. Apple’s closed off the iOS 11.0. and iOS 10 downgrades which means once you download iOS 11 on your device you’re stuck. There’s no going back to anything older than iOS 11.0.1.
Apple will, at some point, stop signing off on iOS 11.0.1 so those of you interested in downgrading will need to move pretty quickly.
Our guide will take you step-by-step through the downgrade process.
iOS 11.0.2 fixes some bugs, but there still are iOS 11 problems. We could see another iOS 11 update roll out in the near future though Apple hasn’t confirmed an iOS 11.0.3 release.
One thing we do know is that the company is planning to deliver an iOS 11.1 update. Apple recently released the second iOS 11.1 beta for iPhone, iPad, and iPod touch.
Apple hasn’t confirmed an iOS 11.1 release date, but it could arrive in late October with two brand new features for iPhone and iPad users.
The company’s promised to deliver several new iOS 11 features in 2017 including Apple Pay Cash and person-to-person Apple Pay payments in Messages.
It’s also planning to bring Unicode 10.0 and its new emoji characters to the iOS 11.1 keyboard. The list of new emojis includes a zombie, a genie, an elf, an exploding head, a mage, a coconut, a sandwich, and a vampire. The iOS 11.1 update will also bring back the 3D Touch App Switcher gesture.
Keep an eye out for new iOS 11.1 betas, and iOS 11 updates, as we push into October.
Install iOS 11.4.1 for Better Security
Apple's iOS 11.4.1 update comes with 15 patches for potential security issues. If you value your security, you should think about installing it today.
iOS 11.4.1 also 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 a certain amount of time.
The new setting is located in Settings > Face ID/Touch ID & Passcode. There you’ll see a new toggle for USB Accessories. It's toggled off by default.
This provides an added layer of protection and prevents the use of cracking tools like GrayKey.
If you skipped iOS 11.4, your iOS 11.4.1 update comes with 30+ patches aimed at improving your device's security. This makes it an essential download for most iPhone and iPad users.
If you missed any of Apple's previous iOS updates, your iOS 11.4.1 update comes with a lot more.
If you skipped iOS 11.3.1, your version of iOS 11.4.1 comes with iOS 11.3.1's four security patches.
If you skipped iOS 11.3, your iOS 11.4.1 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 11.4.1 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 11.4.1.
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 11.4.1 right now.
If you skipped iOS 11.2, you'll get a few more patches with your iOS 11.4.1 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 11.4.1 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 11.4.1 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 11.4.1 update will come with even more security-related 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.
