Autocorrect can seemingly have a mind of its own.

Some users are seeing "A[?]" as the predictive text and autocorrect whenever "I" is typed using the iOS keyboard, according to MacRumors.

The problem seems to affect devices with iOS versions 11.0.3 and 11.1.

Apple support staff recommends using the text replacement function in the settings menu as a temporary fix, according to MacRumors.
