Nevertheless, the Cupertino-based tech giant has recently released a statement which provides a temporary fix for this inconvenient situation. All that you have to do is configure a keyboard typing shortcut to bypass the above mentioned typing bug. Apple confirms that the issue will be permanently fixed in an upcoming software update!
Update: iOS 11.1.1 has just been released to fix this Keyboard autocorrect bug as well as the ‘Hey Siri’ crashing glitch!How To Fix The iOS 11.1 Letter “i” Autocorrect Problem
1. Open Settings from your iPhone / iPad Home screen.
2. Browse for General -> Keyboard -> Text Replacement.
3. Tap the blue “+” icon.
4. Type a capital “I” in the Phrase filed.
5. For Shortcut use the lower-case “i”. Hit Save and you’re ready!
