The iOS 26.4 update that Apple plans to release as soon as next week includes improvements for the built-in iOS keyboard. In its notes for the software, Apple says iOS 26.4 offers "improved keyboard accuracy when typing quickly". There was a bug in iOS that caused some characters to be missed when a user was typing quickly. The character appeared to be tapped in the keyboard, but was ultimately not inserted.
I really wonder if it’ll fix the issue I have. It seems somewhere along the way, the keyboard went from prioritizing where my finger lands to where it lifts from. I am great at striking down where I want, but when my finger starts to travel to the next key, it lifts diagonally instead of vertically, and they keyboard senses it as still touching and moving to the next key over.
That could be part of it. The iOS keyboard has swipe type now, and it’s been kinda shitty at touch typing since around the same time.
