Apple is working on a fix for a bug in iOS 26 that removed the Czech keyboard's caron character (ˇ), locking users out of iPhones whose passcodes used it. Connor Byrne, a 21-year-old student, discovered the issue when his iPhone 13 became inaccessible after the September 2025 update removed the diacritical mark. The fix is expected in an upcoming iOS 26 release after Apple's engineers were alerted via his Reddit post.
