"Apple fans across the world are noticing that everytime they type the letter "i", their phones try to swap it for "a" followed by a "?".
"Also included in the update is the Love-You Gesture, designed after the "I love you" hand sign in American Sign Language".
These fixes aren't flawless but they'll do the trick until Apple issues an update to A [?] OS 11.1.
Apple has since described a workaround for the issue using its text replacement feature.
In a support note, Apple confirmed that some iPhones, iPads, and iPod touch devices running the latest version of its mobile operating system are autocorrecting the letter "i" to the letter "A" with a symbol. In order to turn off Predictive Text just go to Settings General Keyboard Turn Off Auto-Correction and Predictive.
"For Phrase, type an upper-case 'I, '" Apple explains. Given the frequency with which people type the letter "i", this is understandably upsetting many customers.
Apple is aware of the flaw and is working on a fix, and has provided a fix that requires a small amount of work.
User @mcwm tweeted: 'I have a $1,150 [£877] telephone that can't read the letter "i"'.
"For some reason inside the keyboard replacement settings pane, typing an uppercase I works".
The problem likely comes from the autocorrect software, or it could be linked to emojis. Recent revelations note the iOS 11.1 Upgrade Guide suggests users only upgrade if they face battery problems, sound advice considering they already have less to lose.
