Apple in the iOS 26.4 update, expected to be released next week, promises “improved keyboard accuracy when typing quickly.” Apparently, this is a fix for a long-standing and extremely annoying bug that caused the iOS keyboard to insert incorrect letters — even when the user accurately tapped the right key. The problem was so widespread that a YouTube video demonstrating it garnered over a million views.
iOS 26.4: Apple finally fixed the annoying iPhone keyboard bug that ruined the lives of millions of users
iPhone Types Wrong Letters
The bug looked like this: the user presses the correct letter, the keyboard visually highlights exactly that letter — but a different one appears in the text field. This wasn’t a typo or a finger miss: the glitch occurred after the system had already correctly recognized the tap.
The problem was thoroughly documented by YouTube blogger Michi NekoMichi, who recorded the typing process in slow motion. For example, when typing the phrase “thumbs up,” the keyboard periodically replaced the correctly tapped letter “H” with “U.” Disabling autocorrect didn’t help — the bug appeared regardless of this setting.
What was especially frustrating was that many users had spent years blaming their own clumsiness. On MacRumors forums and in video comments, thousands of people wrote that they finally had an explanation for their constant typos. The bug was reproducible on various iPhone models — from iPhone 14 to iPhone 17.
Has Fast Typing on iPhone Been Fixed in iOS 26.4
In the iOS 26.4 update description, Apple concisely states: “improved keyboard accuracy when typing quickly.” The company reveals no details about the technical nature of the bug.

However, as MacRumors notes, there is a high probability that this refers specifically to fixing the very glitch where the keyboard inserted the wrong letter after correctly recognizing the tap. The wording “when typing quickly” matches the conditions under which the bug appeared most frequently.
An important caveat: until iOS 26.4 is released in its final version, the effectiveness of the fix cannot be confirmed. The update is in the beta testing stage — the fourth beta is currently available. The public release is expected by the end of March or in the first days of April 2026.
Should You Update to iOS 26.4
If you’ve noticed that your iPhone “drops” letters or inserts wrong characters when typing quickly — this update is aimed directly at you. The problem was particularly bothersome for those who frequently chat in messengers and type on the go.
For those who haven’t experienced such glitches, the update will still be useful: iOS 26.4 is a major update with new features in Apple Music, Podcasts, and CarPlay, as well as new emoji and other improvements.
Key takeaway: if the iPhone keyboard has been frustrating you with “inexplicable” typos — now there’s a specific reason to update as soon as iOS 26.4 becomes available. For those who haven’t had typing issues, there’s no rush, but there’s also no reason to delay the update.
