5 Things to Know About the iOS 17.4 Update

Apple’s released its new iOS 17.4 update for iPhone and the software is available to download right now.

iOS 17.4 is a milestone upgrade, the fourth for the iPhone’s iOS 17 operating system. As such, it brings more than just bug fixes and security patches to iPhone users. It delivers new features as well.

In this guide we’ll outline iOS 17.4’s changes, offer some thoughts about the software’s performance, go over the current list of  problems plaguing the software, highlight the iOS 17 jailbreak status, and more.

We’ll start with a quick look at iOS 17.4’s performance.

iOS 17.4 Review

If your iPhone’s running iOS 17.3.1, you’ll see the smallest iOS 17.4 download size. The download is around 1.6GB. If your iPhone is running low on storage, you may have to make room for the download.

The iOS 17.4 download size depends on your iPhone model and the version of iOS it’s currently running. If you skipped previous versions of iOS, the download could be quite large because the software brings the changes from updates you skipped.

As for the installation, it took about eight minutes to complete on an iPhone 12 Pro. Mileage will vary, but it should take around the same for most iPhone models.

iOS 17.4 Problems

iOS 17.4 went through an extensive testing process, but the firmware’s causing problems for some iPhone users.

The list of problems includes Wi-Fi issues, random reboots, abnormal battery drain, Bluetooth issues, installation issues, Exchange issues, and problems with first and third-party apps.

If you run into trouble on iOS 17.4, take a look at our list of fixes for the most common iOS 17 problems. We’ve also released tips that could help you improve your phone’s performance and some tips that could help fix battery life issues.

Apple’s signing on iOS 17.3.1 which means you can drop your iPhone’s software back to older software if iOS 17.4 starts causing problems.

You can’t drop back to anything older than iOS 17.3.1. The downgrade path to older software like iOS 17.3 and iOS 17.2.1 is closed and won’t re-open.

iOS 17.4 Features

Apple’s milestone updates (iOS x.x) typically bring new features, enhancements, security patches, and bug fixes to iPhone users and that’s what iOS 17.4 brings to the table.

iOS 17.4 delivers changes to iOS, Safari, and the App Store in the European Union. The changes comply with the EU’s Digital Markets Act (DMA).

Apple says the “changes include more than 600 new APIs, expanded app analytics, functionality for alternative browser engines, and options for processing app payments and distributing iOS apps.”

In addition to these changes, iOS 17.4 brings new emoji characters to the iPhone’s keyboard. The list includes a phoenix, a lime, and an edible mushroom.

The iOS 17.4 update also includes an upgrade to the Podcasts app. The app now features auto-generated transcripts which can be viewed within the app itself.

iOS 17.4 also ushers in quantum security protection for iMessage. The company says the upgrade gives iMessage “the strongest security properties of any at-scale messaging protocol in the world.”

Here are the official iOS 17.4 release notes:

Emoji

• New mushroom, phoenix, lime, broken chain, and shaking heads emoji are now available in the emoji keyboard
• 18 people and body emoji add the option to face them in either direction

Podcasts

• Transcripts let you follow an episode with text that highlights in sync with the audio in English, Spanish, French and German
• Episode text can be read in full, searched for a word or phrase, tapped to play from a specific point and used with accessibility features such as Text Size, Increase Contrast, and VoiceOver

Enhancements & Bug Fixes

• Music recognition lets you add songs you have identified to your Apple Music Playlists and Library, as well as Apple Music Classical
• Siri has a new option to announce messages you receive in any supported language

iOS 17.4 also carries a bunch of new security patches and you can learn more about them on Apple’s security site.

iOS 17.4 Jailbreak

If you still jailbreak, make sure you avoid the iOS 17.4 update.

We don’t expect developers to release a tool that’s compatible with the iOS 17.4 today or at any point in the near future.

If you want to jailbreak your iPhone, you must stay put on older software.

What’s Next

iOS 17.4 was the last confirmed iOS 17 update in Apple’s pipeline, but we expect the company to put new software into beta testing sooner rather than later.

Keep an eye out for the iOS 17.5 beta. We expect it to enter beta testing in the near future ahead of its official release in April or May.

We may also see Apple push iOS 17.4.1 to bridge the gap between iOS 17.4 and iOS 17.5. We’ll let you know if we hear anything concrete.
