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.

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
