Apple's new update fixes a bug that autocorrects the letter "i" to the letter "A" and a symbol. Users started reporting the issue on Nov 6.
Apple has addressed a glitch that caused some iPhones to unexpectedly start auto-correcting the letter "i" to a capital "A" and a question mark. The issue emerged when people updated their phones to version 11.1 of the iOS operating system.
In a tweet, Apple said people could "fix it by installing the latest software update". The update also addresses an issue with Siri.
The problem was highlighted last week when people trying to tweet messages such as "I got a new iPhone" found their posts were appearing as "A[?] got a new iPhone". At the time, Apple outlined a temporary fix for the problem on its website.
