iOS 26.4 will address a long-standing keyboard accuracy issue affecting iPhone users, as revealed in Apple's software notes. The update targets a problem where the autocorrect keyboard sometimes inserts incorrect letters even when users type the right characters, particularly during fast typing. This glitch gained significant attention last year after a viral YouTube video highlighting the issue amassed over a million views, drawing widespread user complaints and media coverage. The fix is expected to prevent the keyboard from inserting wrong letters during rapid typing, resolving a frustrating flaw that disrupted everyday communication.

Apple's patch arrives as the next scheduled iOS release, potentially offering relief to affected users within weeks.
