iOS 17.3.1: A Swift But Important Update for iPhones

Apple recently rolled out the iOS 17.3.1 update for compatible iPhone models. While not a major overhaul, this small point release fixes a fairly annoying bug and offers the usual round of performance patches and improvements.

In this blog post we’ll unpack everything you need to know about updating to iOS 17.3.1. What devices does it support? What bugs have been resolved? And what other changes should you expect? Read on for the full scoop.

Supported iPhone Models

iOS 17.3.1 can be installed on any iPhone model capable of running the overarching iOS 17 platform. This spans a wide range of devices dating back several generations. iPhones compatible with the 17.3.1 release include:

  • iPhone X
  • iPhone XS/iPhone XS Max
  • iPhone XR
  • iPhone 11/iPhone 11 Pro/iPhone 11 Pro Max
  • iPhone SE (2nd and 3rd generation)
  • iPhone 12 mini/iPhone 12/iPhone 12 Pro/iPhone 12 Pro Max
  • iPhone 13 mini/iPhone 13/iPhone 13 Pro/iPhone 13 Pro Max
  • iPhone 14/iPhone 14 Plus/iPhone 14 Pro/iPhone 14 Pro Max

Essentially, iOS 17 and above supports all iPhone models dating back nearly 6 years. So basically any iPhone still in active use today can install the 17.3.1 update.

What’s New in iOS 17.3.1

As a minor point update, iOS 17.3.1 does not introduce major new features or interface changes. Instead, it focuses on fixing bugs, patching security flaws and optimizing performance issues.

Addresses Annoying Keyboard Lag Issue

The main highlight of iOS 17.3.1 is eliminating an obnoxious bug that caused keyboard lag and text overlap when typing quickly. Affecting messaging, emails and other text entry, it resulted in delayed letter rendering and overlapping scrambled text.

Many users complained of this headache-inducing glitch following the iOS 17.3 update. Fortunately 17.3.1 squashes this issue once and for all. Typing responsiveness feels far snappier as a result.

Other Bug Fixes and Patches

Beyond vanquishing the infamous keyboard bug, iOS 17.3.1 likely packs under-the-hood patches solving unpublicized software flaws and optimization issues.

While Apple no longer provides detailed patch notes, expect fixes addressing performance hiccups, app crashes, battery drain complaints, CarPlay problems and similar stability issues.

Possible Undisclosed Security Updates

Another possibility is that iOS 17.3.1 quietly addresses one or more security vulnerabilities recently reported to Apple.

Hackers and researchers frequently responsibly report exploits allowing unauthorized access or manipulation. Apple subsequently diagnoses these reports and issues silent fixes.

So there’s a chance iOS 17.3.1 neutralizes an undisclosed number of security threats. Updating eliminates any associated risks.

Updating to iOS 17.3.1

Installing the iOS 17.3.1 update is straightforward and only takes a few minutes.

Over-The-Air (OTA) Update

The easiest way to update is wirelessly over Wi-Fi by going to Settings > General > Software Update and following the prompts.

Your device will automatically download and install the latest iOS release. Make sure you back up your data first in case anything gets corrupted or lost.

Updating With Finder/iTunes

Alternatively, connect your iPhone, iPad or iPod Touch directly to your computer. Launch Finder on a Mac or iTunes on Windows.

Then select your device, check for the software update availability, and proceed to download and install iOS 17.3.1 to your device.

What to Expect After Updating

The iOS 17.3.1 installation process is pretty seamless and runs automatically after initiating. Here’s the gist of what happens:

  1. Download iOS update OTA or via USB
  2. iPhone restarts and begins installing the release
  3. Apple logo displays with progress bar underneath
  4. Device optimizes apps and finalizes update
  5. Lock screen appears signaling successful update!

Your iPhone should immediately feel snappier with iOS 17.3.1 installed. Try furiously typing messages to confirm the keyboard lag vanishes. And report back if you experience any new issues!

The Bottom Line

While a relatively minor entry in Apple’s iOS update history, iOS 17.3.1 still provides valuable fixes you’ll want to snag. Squashing the typing lag alone makes the quick upgrade worthwhile.

And as always, keeping up to date with the latest iOS version ensures your iPhone benefits from the newest features, security enhancements and device optimizations. So go ahead and update for an all-around improved experience!
